Chapter 9: Guidelines for the Provision of Anaesthesia Services for an Obstetric Population 2024

Published: 31/01/2023


Pregnancy and childbirth remains a risky time for both mother and baby. In recent years, we have seen the maternal mortality rate plateau.7,8,9 

However, the confidential review of every maternal death over the past seven decades continues to identify that substandard care, frequently caused by deficiencies in service provision, has led to avoidable deaths in the majority of cases. Areas where improvements can be made to reduce the risk for mothers and babies are identified in every report. It is vital that we use this shared learning and the available evidence to shape our provision of care to pregnant and recently delivered women, both here in the UK and with the wider population globally.

Working on delivery units can be incredibly rewarding, but it can also be highly challenging and dynamic. It is not possible to identify all women or babies who are at risk of rapid deterioration but we do need to be able to respond appropriately and in a timely manner in the event of an emergency. Obstetrics accounts for a large proportion of the emergency surgery performed in hospitals.10,11 

Provision of obstetric care is by its nature multidisciplinary. The team, which includes, obstetricians, anaesthetists, neonatologists, midwives, theatre staff, anaesthetic assistants and others, has to be able to work closely under stress in dynamic situations. To ensure that teams can function effectively in this environment, they need to train together and have the appropriate infrastructure and necessary resources in place to deliver a high-quality service.

The role of the anaesthetist on the delivery unit encompasses that of a peripartum physician and has expanded markedly in recent years. Over 50% of women require anaesthetic intervention around the time of delivery of their baby12. It is currently difficult to quantify other areas of care provided by anaesthetists on delivery suites.13  Some evidence suggests that there has been a recent increase in the requirement for labour induction; in addition, anaesthetic care is required for operative/assisted deliveries and other procedures during pregnancy or the peripartum period.14 

Anaesthetists are also involved in planning the care of high-risk women during the antenatal period and with providing higher levels of care in the peripartum period.

The obstetric population is changing; over half of pregnant women are now considered to be at high risk for complications during their pregnancies.15 In 2015, the greatest increase in fertility rate was for women aged 40 years and over (a group that has been identified as at high risk of mortality) and a large proportion of pregnancies in this age group are the result of assisted conception. In the UK, one in six couples seeks fertility treatment. The resulting pregnancies are associated with more complications for both women and their babies. The incidence of obesity also continues to rise across the UK population.10,16,17 

The number of women who have had a previous caesarean birth is rising, increasing the risks of associated placenta accreta syndrome and uterine rupture. The number of pregnant women with significant pre-existing conditions (e.g. congenital cardiac disease) who are proceeding with their pregnancies is increasing. These women require specialised services to support them during this time. These guidelines include recommendations for areas of service where anaesthetists are expected to take a lead role but, as a pregnant woman may present anywhere, all maternity units should be ready to recognise and manage acute deterioration, with pathways in place to obtain expert guidance when required.

Public expectations of maternity services are high; through media, internet and educational resources, pregnant women and their families are often well informed. Many are keen for a particular mode of delivery or type of analgesia. We have to deliver an anaesthesia service that is safe and effective and that also aims to meet these expectations, where appropriate. It is vital that we adopt the principles of shared decision making and that we recognise the need to support autonomy by building good relationships, respecting both individual competence and interdependence on others.14,18

In 2022, two major reports related to maternity services were published; Ockenden and Kirkup.19 The Ockenden Report made several recommendations specifically relating to obstetric anaesthetic services. These align with existing GPAS recommendations and are referenced in the text.

1. Staffing requirements

The duty anaesthetist

The duty anaesthetist is responsible for providing care to those in labour or who, in the antenatal, perinatal or postpartum period, require anaesthetic, medical or surgical attention. The duty anaesthetist can be a consultant, an SAS doctor, clinical fellow or anaesthetic trainee.


To act as the duty anaesthetist without direct supervision from a consultant or autonomously practising anaesthetist, the duty anaesthetist should meet the basic training specifications and have attained the RCoA’s Initial Assessment of Competence in Obstetric Anaesthesia.20,21

B Strong

There should be a duty anaesthetist immediately available for the obstetric unit 24/7. As their primary responsibility is to provide care to those in labour or who require medical or surgical interventions, ante or peripartum, the role should not include undertaking elective work during the duty period.22

C Strong

Busier units (see Glossary) should consider having two duty anaesthetists available 24/7, in addition to the supervising autonomously practising anaesthetist.23

C Strong

In units offering a 24-hour regional analgesia service, the duty anaesthetist should be resident on the hospital site where the regional analgesia is provided (not at a nearby hospital).

GPP Strong

The duty anaesthetist should have an effective and rapid means of communication with their supervisor at all times.23 Staff working in the maternity unit should be aware of their supervisor’s identity, location and how to contact them. The name(s) of the autonomously practising anaesthetist(s) covering the delivery suite and how to contact them should be clearly displayed and easily visible to all staff.24 There should be guidelines for escalation to the consultant on-call with specific guidance for consultant attendance.25

B Strong

It is recognised that, in smaller units, the workload may not justify having an anaesthetist exclusively dedicated to the delivery unit. If the duty anaesthetist does have other responsibilities, these should be of a nature that would allow the activity to be immediately delayed or interrupted should obstetric work arise. Under these circumstances, the duty anaesthetist should be able to delegate care of their non-obstetric patient to be able to respond immediately to a request for care of obstetric patients. They would therefore, for example, not simultaneously be able to be a member of the on-call resuscitation team. If the duty anaesthetist covers general theatres, another anaesthetist should be ready to take over immediately should they be needed to care for obstetric patients.

GPP Strong

Adequate time for formal multidisciplinary team (MDT) handovers between shifts should be built into the timetable. In the case of the anaesthetist being otherwise engaged with work at the time of the MDT labour ward handover, a briefing from the midwifery and obstetric team should be sought at the earliest opportunity to facilitate a shared mental model of the existing workload/potential patients.2,24

GPP Strong

A structured tool should be considered for handover between shifts and its formal documentation.23,24,26

B Moderate

The duty anaesthetist should participate in MDT delivery suite handovers and ward rounds.24,27

C Strong

The lead obstetric anaesthetist


Every obstetric unit should have a designated lead anaesthetist (see Glossary) with specific programmed activities allocated for this role.2

GPP Strong

The lead obstetric anaesthetist should be responsible for the overall delivery of the service, including:

  • ensuring that evidence based guidelines and protocols are in use and are up to date
  • monitoring staff training
  • workforce planning
  • service risk management
  • ensuring that national specifications are met
  • auditing the service against agreed standards, including anaesthetic complication rates, as set out in the RCoA QI Compendium Chapter 7.
GPP Strong

The lead obstetric anaesthetist should ensure representation of the anaesthetic department at multidisciplinary meetings for service planning and governance purposes, including labour ward forum, risk management groups and incident reviews.22,24

C Strong

The lead obstetric anaesthetist should ensure that there are continuing quality improvement projects to maintain and improve the care in their units.28

C Strong

Consultant or other autonomously practising anaesthetist


As a basic minimum for any obstetric unit, a consultant or other autonomously practising anaesthetist should be allocated to ensure senior cover for the full daytime working week; that is, ensuring that Monday to Friday morning and afternoon sessions (see Glossary), are staffed.22 This cover is to provide urgent and emergency care, not to undertake elective work.

C Strong

In busier units, increased levels of consultant or other autonomously practising anaesthetist cover may be necessary and should reflect the level of consultant obstetrician staffing in the unit.29 This may involve extending the working day to include senior presence into the evening session and/or increasing numbers of autonomously practising anaesthetists.

C Moderate

Additional programmed activities for consultant or autonomously practising anaesthetists should be allocated for elective caesarean birth lists and antenatal anaesthetic clinics (or to review referrals if no formal clinic is in place).23 Time is required to identify and follow up potential anaesthetic morbidity and to arrange continuing investigation and referral.

C Strong

In units where anaesthetists in training work a full or partial shift system and/or rotate through the department every three months (or more frequently), provision of additional programmed activities for autonomously practising anaesthetists should be considered, to allow initial orientation, training and supervision into the evening.30

C Moderate

There should be a named consultant or other autonomously practising anaesthetist responsible for every elective caesarean delivery list. This anaesthetist should be immediately available. The named person should have no other concurrent clinical responsibilities.

GPP Strong

Consultant or other autonomously practising anaesthetist support should be contactable at all times and have a response time for attendance on site of not more than half an hour to attend the delivery suite and maternity operating theatre. The supervising anaesthetist should not therefore be responsible for two or more geographically separate obstetric units.

GPP Strong

The anaesthetist’s primary responsibility is care of the woman. A separate healthcare professional should be responsible for neonatal resuscitation and the care of the newborn baby.167,31

B Strong

Anaesthetic assistance


Women requiring anaesthesia in the peripartum period should have the same standards of perioperative care as for any surgical and medical patient.6,32

B Strong

The anaesthetist should have a competent trained assistant immediately available for the duration of any anaesthetic intervention and this practitioner should not have any other duties.33

C Strong

All theatre staff acting as anaesthesia assistants should comply fully with current national training standards, and should be required to have attained and maintained the relevant competencies to perform the role (an example of these competencies is referenced).33,34

C Strong

Anaesthetic practitioners who cover obstetrics should demonstrate additional knowledge and skills specific to the care of pregnant women.34

C Strong

Anaesthetists and anaesthesia assistants working without direct supervision in obstetric theatres and on the delivery suite should be familiar with the environment and working practices of that unit and work there on a regular basis to maintain that familiarity.

GPP Strong

Postanaesthetic recovery staff


Those requiring postoperative recovery care should receive the same standard of care as the non-obstetric postoperative population.6,34,35,36,37

B Strong

All staff caring for the obstetric population following anaesthesia should be familiar with the area for recovery of obstetric patients and be experienced in the use of the different early warning scoring systems for obstetric patients. They should have been trained to the same standard as for all recovery practitioners working in other areas of general surgical work, should maintain their skills through regular work on the theatre recovery unit and should have undergone a supernumerary preceptorship in this environment before undertaking unsupervised work.35,38

B Strong

Other members of the team


An adult resuscitation team trained in resuscitation of the pregnant patient should be immediately available.39

C Strong

There should be secretarial support for the department of anaesthesia, including the obstetric anaesthetic service.

GPP Strong

Provision should be made to ensure access to other allied healthcare professionals, such as clinical pharmacists, dieticians, outreach nurses and physiotherapists, is available if required.40

C Strong

Hospitals should have approved documentation defining safe staffing levels for anaesthetists and anaesthetic practitioners, including contingency arrangements for managing staffing shortfalls; annual reviews of compliance with these standards should be performed.

GPP Strong

2. Equipment, services and facilities



Blood gas analysis (with the facility to measure serum lactate and the facility for rapid estimation of haemoglobin and blood sugar) should be available on the delivery suite.

GPP Strong

Delivery suite rooms should be equipped with monitoring equipment to measure non-invasive blood pressure, oxygen saturation and heart rate.

GPP Strong

C Strong

A fluid warming device allowing rapid infusion of blood products and intravenous fluids should be immediately available to the delivery suite.44

C Strong

In tertiary units with a high-risk population it is recommended that there should be equipment to enable near-patient estimation of coagulation.44

C Moderate

Cell salvage may be considered for women who refuse blood products or where massive obstetric haemorrhage is anticipated but it should not be used routinely for caesarean birth. When cell salvage is required, staff who operate this equipment should have received training and should maintain the appropriate skills to continue to do so.45,46,47,48

A Strong

Devices such as warming mattresses and forced air warmers should be available to prevent and treat hypothermia.49,50

C Strong

A difficult intubation trolley with a variety of laryngoscopes including video laryngoscopes, tracheal tubes (size 7 and smaller), second-generation supraglottic airway devices, equipment for emergency front of neck and other aids for difficult airway management should be available in theatre. Videolaryngoscope should always be available. The difficult intubation trolley should have a standard layout that is identical to trolleys in other parts of the hospital so that users will find the same equipment and layout in all sites. The Obstetric Anaesthetists Association/Difficult Airway Society difficult and failed tracheal intubation algorithms should be displayed.4551,52

B Strong

Patient controlled analgesia equipment should be available for postoperative pain relief, and staff should be trained in its use and how to look after women using the equipment.53

C Strong

Ultrasound imaging equipment should be available to anaesthetists trained in its use for central vascular access and transversus abdominis plane blocks. Where staff have the relevant competencies, ultrasound may also be useful for other tasks.54,55,56,57

C Strong

An intraosseous access insertion device should be immediately available.

GPP Strong

Synchronised clocks should be present in all delivery rooms and theatres to facilitate the accurate recording of events and to comply with medicolegal requirements.58

C Strong

Resuscitation equipment as described by the Resuscitation Council UK should be available on the delivery suite and should be checked regularly.59 A resuscitative hysterotomy pack containing a scalpel, surgical gloves and cord clamp should be available on all resuscitation trolleys in the Maternity Unit and areas admitting pregnant women e.g. emergency departments.60 A range of sizes of endotracheal tubes of 7 mm internal diameter or less should also be kept on the resuscitation trolleys.9,61

B Strong

Support services


There should be arrangements or standing orders in place for agreed preoperative laboratory investigations.62

GPP Strong

There should be a standard prescription or a local patient group directive for preoperative antacid prophylaxis.63,64

GPP Strong

Haematology and biochemistry services to provide analysis of blood and other body fluids should be available 24/7. Anaesthetists should be represented on blood user groups.

GPP Strong

A local policy should be established with the transfusion services to ensure that blood products, once available, are transferred to the delivery suite rapidly for the management of major haemorrhage.44

C Strong

Group O Rhesus negative blood should be immediately (see Glossary) available. To enable immediate availability, most units will require a blood fridge located within the delivery suite.

GPP Strong

There should be rapid availability of radiology services.65

GPP Strong

In tertiary referral centres, there should be 24-hour access to interventional radiology, computed tomography and magnetic resonance imaging services.65,66,67

GPP Moderate

Echocardiography services should be available at all times in units that routinely deal with cardiac patients.6

B Moderate

Robust and reliable local arrangements should be in place to ensure the supply and maintenance of all medicines required for obstetric anaesthesia. There must be a system for ordering, storage, recording and auditing controlled drug use, according to legislation.68,69,70

M Strong

There should be access to a clinical pharmacist of an appropriate competency level and expertise in obstetrics. They should advise on day-to-day medication or prescribing issues in the obstetric population and should provide input in local policies and procedures about any aspects of medicines management.71,72 Where possible, hospitals should follow national guidance for drug shortages and this should guide local practice.73

C Strong

Preprepared drugs should be used where available, including sterile ampoules or bags of low-dose local anaesthetic combined with opioid solutions for regional analgesia. Prefilled syringes of commonly used emergency drugs (e.g. suxamethonium and phenylephrine) should be used where available.74

C Strong

Local anaesthetic solutions intended for epidural infusion should be stored separately from intravenous infusion solutions to minimise the risk of accidental intravenous administration of such drugs.75

C Strong

Medication for life threatening anaesthetic emergencies should be immediately available to the delivery suite and their location should be clearly identified. There should be a clear local agreement on the responsibility for maintenance of these emergency medicines (i.e. regular checks of stock levels, integrity and expiry dates).59

GPP Strong

Physiotherapy services should be available 24/7 for patients requiring higher levels of care.76

GPP Strong



There should be easy and safe access to the delivery suite from the main hospital at all times.77

GPP Strong

An emergency call system should be provided.77

GPP Strong

There should be at least one fully equipped obstetric theatre within the delivery suite or immediately adjacent to it. Appropriately trained staff should be available to allow emergency operative deliveries to be undertaken without delay.167 The number of operating theatres available for obstetric procedures will depend on the number of deliveries and the operative risk profile of the women delivering in the unit

C Strong

Medication storage facilities should be available within maternity theatres to provide timely access to medicines when clinically required, while maintaining integrity of the medicinal product and allowing the organisation to comply with regulations on the safe and secure storage of medicines.71,79

C Strong

Adequate recovery room facilities that comply with the Association of Anaesthetists’ recommendations for standards of monitoring during anaesthesia and recovery should be available within the delivery suite theatre complex.43

C Strong

Anaesthetic machines, monitoring and infusion equipment and near-patient testing devices should be maintained, repaired and calibrated by medical physics technicians.80

GPP Strong

An anaesthetic office, located within five minutes’ walk of the delivery suite, should be available to the duty anaesthetic team. The room should have a computer with intra/internet access to specialist reference material and local multidisciplinary evidence based guidelines and policies. The office space, facilities and furniture should comply with the Association of Anaesthetists' standards.81 This office could also be used to allow teaching, assessment and appraisal.82


A communal rest room should be provided in the delivery suite to enable staff of all specialties to meet.83

GPP Strong

A seminar room should be accessible for training, teaching and multidisciplinary meetings.83

GPP Strong

All hospitals should ensure the availability of areas that allow those doctors working night shifts to take rest breaks, which are essential for the reduction of fatigue and improve safety.28 These areas should not be used by more than one person at a time and should allow the doctor to fully recline.84

C Strong

Standards of accommodation for doctors in training should be adhered to.29 Where a consultant or other autonomously practising anaesthetist is required to be resident, on-call accommodation should be provided.28

C Strong

Hotel services should provide suitable on-call facilities, including housekeeping services for resident and non-resident anaesthetic staff. Refreshments should be available 24/7.84

GPP Strong

C Strong

3. Special populations


Care for the acutely ill obstetric patient and NICE guidance on the recognition of and response to acute illness in adults in hospitals should be implemented.40,93,94

C Strong

An early warning score system, modified for use in obstetrics, with a graded response system should be used for all obstetric patients to aid early recognition and treatment of the acutely ill woman.95,96,97,98

B Strong

All units should be able to escalate care to an appropriate level; critical care support should be provided if required, regardless of location.40

C Strong

Whenever possible, escalation in care should not lead to the separation of mother and baby. When separation is unavoidable, the duration should be minimised.9,40,99

B Strong

Midwives working in enhanced care areas or providing enhanced care to patients should have the appropriate training.40,100

C Strong

There should be a named consultant or other autonomously practising anaesthetist and obstetrician responsible 24/7 for all women requiring a higher level of care.40

GPP Strong

Women requiring critical care in a non-obstetric facility should be reviewed daily by a maternity team that includes an obstetric anaesthetist.11

B Strong

The obstetric anaesthetist should be informed and should be consulted when there is a multidisciplinary transfer of care of a pregnant or postpartum woman. This is particularly important when there is a physical transfer of care (e.g. transfer to or from a critical care ward or another hospital), which should necessitate direct communication between the obstetric anaesthetist and the other anaesthetists/intensivists involved in the transfer of care.

GPP Strong

All units should have facilities, equipment and appropriately trained staff to provide care for acutely ill obstetric patients. If they are unavailable, patients should be transferred to the general critical care area in the same hospital with staff trained to provide care to obstetric patients.

GPP Strong

All patients should be able to access level 3 critical care if required. Units without such provision on site should have an arrangement with a nominated level 3 critical care unit and an agreed policy for the stabilisation and safe transfer of patients to this unit when required.40,59 Portable monitoring with the facility for invasive monitoring should be available to facilitate safe transfer of obstetric patients to intensive care.101

GPP Strong

Care for the obese woman

Obesity is associated with an increased incidence of both obstetric and medical complications.102


There should be a system in place for antenatal anaesthetic review by a senior anaesthetist for women who are morbidly obese.103 Assessment should be arranged to ensure that timely delivery planning can take place.104

C Strong

The duty anaesthetist should be informed as soon as a woman with a BMI above a locally agreed threshold is admitted.

GPP Strong

Equipment to facilitate the care of women with morbidly obesity (including specialised electrically operated beds, operating tables with suitable width extensions and positioning aids, such as commercially produced ramping pillows, extra-long spinal and epidural needles, weighing scales, sliding sheets and hover mattresses or hoists) should be readily available. Staff should receive training on how to use the specialised equipment.105 The maximum weight that the operating table can support should be known and alternative provision made for women who exceed this weight.

C Strong

Care for women under the age of 18 years

The following recommendations apply to units that admit young women and girls under the age of 18 years for obstetric services.


There should be a multidisciplinary protocol governing care of young women and girls under the age of 18 years that includes consent, the environment in which patients are cared for, and the staff responsible for caring for these young women.

GPP Strong

Anaesthetists should be aware of legislation and good practice guidance relevant to children and according to the location in the UK.106,107,108,109,110,111,112 These documents refer to the rights of the child, child protection processes and consent.

M Strong

Anaesthetists must undertake at least level 2 training in safeguarding/child protection,110 and must maintain this level of competence by regular annual updates on current policy and practice and case discussion.114

M Mandatory

At least one anaesthetist in each anaesthesia department, not necessarily an obstetric anaesthetist, should take the lead in safeguarding/child protection; they should undertake training and maintain core level 3 competencies.115 The lead anaesthetist for safeguarding/child protection should liaise with their multidisciplinary counterparts within the obstetric unit.

C Strong

Care for women requiring specialist services


There should be policies defining how women are referred to and access specialist or tertiary services (e.g. neurosurgery, acute stroke services).9,116,117

C Strong

Patients who decline to have transfusion of blood and blood products


Those who refuse transfusion of blood or blood products, whether because of adherence to the Jehovah’s Witness faith or for other reasons, should be identified early in the antenatal period. They should meet with an anaesthetist to discuss their specific wishes and should receive information about the potential risks associated with their decision to ensure informed consent process.118,119,117 Such conversations should be conducted with appropriate privacy to avoid the risk of coercion. Their decision should be documented and shared with the MDT to plan for delivery with the appropriate equipment and resources available.

C Strong

4. Training and education


All anaesthetists involved in the care of pregnant women should be competent to deliver high quality safe care that considers the physiological changes and other specific requirements of these pregnant women.121

C Strong

There should be a nominated anaesthetist responsible for training in obstetric anaesthesia, with adequate programmed activities allocated for these responsibilities.59

GPP Strong

A process should be in place for the formal assessment of anaesthetists before allowing them to join the on-call rota for obstetric anaesthesia with distant supervision.20,122

C Strong

In-situ simulation training can help to identify system process gaps.123 Simulation based learning techniques should assist anaesthetists in resolving these issues and developing the necessary technical and non-technical skills.124,125,126,127,128,129,130,131,132

B Strong

All anaesthetists working in the maternity unit should have received training in human factors, addressing key factors including situational awareness, effective teamworking and communication, decision making and the effect of biases.133,134

B Strong

There should be induction programmes for all new members of staff, including locum doctors. Induction for a locum doctor should include the following and should be documented:

  •  familiarisation with the layout of the labour ward
  • the location of emergency equipment and drugs (e.g. massive obstetric haemorrhage trolley/intralipid/dantrolene)
  • access to guidelines and protocols
  •  information on how to summon support/assistance

assurance that the locum is capable of using the equipment in that obstetric unit.

GPP Strong

Any autonomously practising anaesthetist providing cover for the labour ward regularly or on an ad hoc basis must undertake continuing professional development (CPD) in obstetric anaesthesia and must have enough exposure to obstetric patients to maintain appropriate skills. This could be achieved through allocation of supernumerary sessions on the labour ward or in elective caesarean lists while reviewing appropriate CPD during the appraisal process.25,135

M Mandatory

Any non trainee anaesthetist who undertakes anaesthetic duties in the labour ward should have been assessed as competent to perform these duties in accordance with RCoA guidelines.20

C Strong

Anaesthetists who primarily work on the labour ward during the night should be given opportunities to work on the labour ward during the daytime on weekdays.25

GPP Strong

Any anaesthetist working on the labour ward should also regularly undertake non-obstetric work to ensure maintenance of a broad range of skills.

GPP Strong

All staff working on the delivery suite should have annual resuscitation training, including the specific challenges of pregnant women.91

C Strong

Anaesthetists should contribute to the education and updating of midwives, anaesthesia assistants, obstetricians and intensive care staff involved in the care of maternity patients.25

GPP Strong

Anaesthetists should help to organise and participate in regular multidisciplinary courses and ‘skills and drills’ for emergencies.8,25,88,129,130,131

B Strong

5. Organisation and administration



A system should be in place to ensure that those requiring antenatal and postnatal anaesthetic referral are seen and assessed by a senior obstetric anaesthetist, usually an autonomously practising anaesthetist, within a suitable time frame. Where the workload is high, consideration should be given to risk stratification so that not all women are required to attend in person, by using targeted telemedicine and/or distribution of relevant literature.25,32,136

C Strong

An anaesthetist should be included in the MDT antenatal management planning for those with complex medical needs.3 Planning should be in the form of shared decision making and include consideration of the woman’s wishes and preferences.136,137

GPP Strong

All pregnant women requiring caesarean birth should, except in an extreme emergency, be visited and assessed by an anaesthetist before arrival in the operating theatre. This should allow sufficient time to weigh up the information to give informed consent for anaesthesia.137

GPP Strong

There should be a local guideline on monitoring of women after regional anaesthesia and the management of postanaesthetic neurological complications.

C Strong

All women who have received an anaesthetic intervention for labour and/or delivery should be reviewed postnatally. Locally agreed discharge criteria should be met before they go home and written information should be provided.25,138

C Strong

There should be local guidelines on preoperative, intraoperative and postoperative care for those cases where an enhanced recovery process is appropriate.139

C Strong

Units with high numbers of caesarean births should have specific lists to minimise disruption due to emergency work.140 Any elective caesarean delivery list should have dedicated obstetric, anaesthetic and theatre staff and should take place in a separate theatre to where emergency cases are undertaken.141

B Strong



All pregnant women must be assumed to have capacity unless there is evidence to the contrary, as per the Mental Capacity Act.137,142,143

M Mandatory

There should be documentation of any discussions involving informed consent for any procedures undertaken by the anaesthetist.137,142

M Strong

Those with potential issues with their capacity to consent should be identified early in the antenatal period. Arrangements should be made to both to maximise their capacity and to ensure that they are adequately represented and advocated for, in keeping with current legislation.137,142,143

M Strong

The provision of analgesia on the labour ward


Obstetric units should be able to provide regional analgesia on request. Smaller units may be unable to provide a 24-hour service; those booking at such units should be made aware that regional analgesia may not always be available.59

GPP Strong

Midwifery care of a pregnant woman receiving regional analgesia in labour should comply with local guidelines that have been agreed with the anaesthetic department. Local guidelines should include required competencies, maintenance of those competencies and frequency of training. If the level of midwifery staffing is considered inadequate, regional analgesia should not be provided.165

C Strong

Units should have local guidelines on the recognition and management of complications of regional analgesia that include training on the recognition of complications and access to appropriate imaging facilities when neurological injury is suspected. The patient’s general practitioner should be informed in the event of any of these complications.15,136

C Strong

Units should provide low-dose regional analgesia.144,145

A Strong

Regional analgesia should not be used in labour unless the obstetric team is immediately available.

GPP Strong

There should be a locally developed regional analgesia record and a protocol for the prescription and administration of drugs.

GPP Strong

When the anaesthetist is informed of a request for regional analgesia (and the circumstances would be suitable for this type of analgesia) the anaesthetist should attend within 30 minutes of being informed. Only in exceptional circumstances should this period be longer, and in all cases attendance should be within one hour. There should be a clear escalation plan for instances where analgesia cannot be performed within this timeframe. This should be the subject of regular audits.28,146

C Strong

Units that provide remifentanil patient controlled anaesthesia for labour analgesia should have policies and processes in place to ensure that it is used safely, that midwives who care for women using it are familiar with its use and have received specific training. Unit staffing levels should permit continuous midwifery supervision of its use.

GPP Strong

Emergency caesarean birth


There should be a clear line of communication between the duty anaesthetist, theatre staff and anaesthetic practitioner once a decision is made to undertake an emergency caesarean birth.

GPP Strong

The anaesthetist should be informed about the category of urgency of caesarean birth and the indication for surgery at the earliest opportunity.147

C Strong

A World Health Organization (WHO) checklist adapted for maternity should be used in theatre.148

B Strong

There should be clear arrangements for contingency plans and an escalation policy should two emergencies occur simultaneously, including whom to call.

GPP Strong

The multidisciplinary team

Teams rather than individuals deliver care to pregnant women. Effective teamwork has been shown to increase safety, while poor teamwork has the opposite effect.95,126 It is, therefore, important that obstetric anaesthetists develop effective leadership and team membership skills, with good working relationships and lines of communication with all other professionals. This includes midwives, obstetricians, neonatologists and professionals from other disciplines such as intensive care, physicians (including neurology, cardiology and haematology), radiology, general practitioners and surgeons.


Team briefing and the WHO checklist should be in routine use on the labour ward to promote good communication and teamworking and reduce adverse incidents.147,148,149,150

B Strong

If any major restructuring of the provision of local maternity services are planned, the lead obstetric anaesthetist should be involved in that process.22,25

GPP Strong

Anaesthesia should be represented on all committees responsible for maternity services (e.g. the maternity services liaison committee, delivery suite forum, obstetric multidisciplinary guidelines committee, obstetric risk management committee).22,25.59

C Strong

Hospitals should have systems in place to facilitate multidisciplinary morbidity and mortality meetings.25,151

C Strong

Anaesthetists should be an integral part of locally developed networks looking at obstetric services.25

GPP Strong

Serious incidents


When members of the healthcare team are involved in a critical incident, they can be profoundly affected. A team debriefing should take place immediately after a significant critical incident. The lead clinician should review the clinical commitments of the staff concerned promptly. Further practical and psychological support may be necessary to assist individuals to recover from a traumatic event.25

GPP Strong

There should be local governance measures in place to respond to serious incidents. These measures should protect patients and ensure that trained safety leads carry out robust investigations. When an incident occurs, it should be reported to all relevant bodies within and beyond the hospital. A system of peer review or external evaluation of serious incident reports should be in place.25,152,153

C Strong

An anaesthetist should be involved in all case reviews where the case includes anaesthetic input.2

C Strong

6. Quality improvement, audit and research


The lead obstetric anaesthetist should audit and monitor the duty anaesthetist’s workload to ensure that there is sufficient provision within the unit. Senior management should be made aware of any deficiencies found.

GPP Strong

There should be effective governance systems and processes in place to assess, monitor and improve the quality and safety of services with particular reference to local guidelines, reviews of adverse events, and record keeping.23,25

C Strong

There should be organisational support provided to facilitate data collection and analysis in obstetric anaesthesia to assist with quality improvement and benchmarking.25,154

C Strong

All cases of maternal death, significant permanent neurological deficit, failed intubation or awareness during general anaesthesia should undergo case review, with learning from this shared locally and/or nationally (by reporting to MBRRACE).29

C Strong

Research in obstetric anaesthesia and analgesia should be encouraged. Research must follow strict ethical standards as stated by the GMC and Good Clinical Practice guidelines.155

M Mandatory

7. Patient communication and information

It is important that a patient is acknowledged as an individual and that care and services are tailored to respond to their needs, preferences and values. Part of that process is providing information, oral and written, to enable patients to have informed participation in their care.

For the obstetric population requiring anaesthetist delivered care, examples of information resources, both written and visual, are available on the public information website ( provided by the Obstetric Anaesthetists’ Association, which includes translations of these resources in over 20 languages. The Royal College of Anaesthetists has developed a range of Trusted Information Creator Kitemark accredited patient information resources not specific for the obstetric population that can be accessed from the RCoA website. Our main leaflets are now translated into more than 20 languages, including Welsh.


Early on in the antenatal period women should be informed of the analgesic options available in their planned delivery location, so that they can make informed decision about their place of birth.59

GPP Strong

Every unit should provide, in early pregnancy, advice about pain relief and anaesthesia during labour and delivery. An anaesthetist should be involved in preparing this information and should approve the final version.142

C Strong

Pregnant women should have access to information about the differing modes of delivery during the antenatal period and should be offered the opportunity to speak to an anaesthetist if they wish to discuss how this might affect their choices around analgesia and anaesthesia.142,156,157,158

C Strong

Information should be made available to non-English speaking women in their native languages.159,160

C Strong

Units should consider local demographics, such as the prevalence of particular languages, when designing information or commissioning interpreting services.

GPP Strong

Hospitals should ensure that the individual need for information in other languages should be assessed and recorded during antenatal care so that interpreting services can be planned for.

GPP Strong

Interpreting services should be made available for non-English speaking women, with particular attention paid to how quickly such services can be mobilised and their availability out of hours.

GPP Strong

Face to face interpreting services should be considered as most suitable, given the practical requirements for women in labour. However, telephone based services may be able to serve a greater number of languages and be more quickly mobilised, particularly out of hours.

GPP Strong

The use of family members to interpret or translate should be avoided unless absolutely necessary or an independent interpreter is specifically declined. It should be a rare occurrence that there is no alternative translation method available.161,162

C Strong

All information given to women and their consent to undergo obstetric anaesthetic procedures should be clearly documented in their records.

GPP Strong



If complaints are made about anaesthetic aspects of care, a consultant or other autonomously practising anaesthetist should review and assess the patient’s complaint, discussing her concerns and examining her where appropriate. This should be clearly documented alongside any subsequent action taken. Referral for further investigations may be required.

GPP Strong

Complaints should be handled according to local policies.

GPP Moderate

The lead obstetric anaesthetist should be made aware of all complaints.

GPP Strong

8. Financial considerations

There is a paucity of evidence regarding the financial implications of many of the recommendations we make here, The vast majority of units will already adhere to most of the standards outlined. Many of the recommendations represent a financial impact on workforce and time allowance and this should be dealt with in robust job planning and specification in each anaesthetic department and, if required, at trust or board level.

The acquisition of specific equipment and its continuing use and maintenance may have implications for capital and operational expenditure. Recommendations are made based on evidence that there is a cost-effective benefit to patients in terms of outcome and/or improved safety. Local business cases and action plans may need to be developed. The cost of implementing any recommendations should always be considered in relation to the financial risks and human cost of providing substandard care.

Any service implications will have to be considered against the background of the need for all NHS trusts in England and Wales to reduce expenditure.114 It is not the purpose of this guidance to dictate how these recommendations are met – that is to be decided locally. Individual trusts/boards and their executives will need to consider the continuing viability of any maternity unit that continues to fail to meet these standards. The amalgamation or formalised intertrust/board partnerships of smaller consultant-led units, for example, which are an effort to pool resources more efficiently, may require consideration if service provision consistently falls short of the expected standards.

9. Implementation support

The Anaesthesia Clinical Services Accreditation (ACSA) scheme run by the RCoA aims to provide support for departments of anaesthesia to implement the recommendations contained in the GPAS chapters. The scheme provides a set of standards and asks departments of anaesthesia to benchmark themselves against them using a self-assessment form available on the RCoA website. Every standard in ACSA is based on recommendation(s) contained in GPAS. The ACSA standards are reviewed annually and republished approximately four months after GPAS review and republication to ensure that they reflect current GPAS recommendations. ACSA standards include links to the relevant GPAS recommendations so that departments can refer to them while working through their gap analyses.

Departments of anaesthesia can subscribe to the ACSA process on payment of an appropriate fee. Once subscribed, they are provided with a ‘College guide’ (a member of the RCoA working group who oversees the process) or an experienced reviewer to assist them with identifying actions required to meet the standards. Departments must demonstrate adherence to all ‘priority one’ standards listed in the standards document to receive accreditation from the RCoA. This is confirmed during a visit to the department by a group of four ACSA reviewers (two clinical reviewers, a PatientsVoices@RCoA reviewer and an administrator) who submit a report back to the ACSA committee.

The ACSA committee has committed to building a ‘good practice library’, which will be used to collect and share documentation such as policies and checklists, as well as case studies of how departments have overcome barriers to implementation of the standards or have implemented the standards in innovative ways.

One of the outcomes of the ACSA process is to test the standards (and by doing so to test the GPAS recommendations) to ensure that they can be implemented by departments of anaesthesia and to consider any difficulties that may result from implementation. The ACSA committee has committed to measuring and reporting feedback of this type from departments engaging in the scheme back to the chapter development groups updating the guidance via the GPAS technical team.

Areas for future development

Areas of research currently identified as deficient by the GPAS chapter development group include:9

  • criteria for defining obstetric or obstetric anaesthetic workload (may be different)
  • organisation of elective obstetric services
  • optimal service provision for acutely ill obstetric patients.


Autonomously practising anaesthetists – a consultant or a staff grade, associate specialist or specialty (SAS) doctor who can function autonomously to a level of defined competencies, as agreed within local clinical governance frameworks.

Busy units – the workloads of a unit cannot be defined solely by the number of births. For an individual anaesthesia department the workload comprises the number of women seen in the anaesthetic antenatal clinics, the number of anaesthetic procedures for labour, delivery and other operative intervention, the complexity of the case mix, the number of critically ill patients requiring anaesthetic input and the number of patients requiring obstetric anaesthetic follow up post-delivery for anaesthesia-related morbidity and debriefing.163 In this document, the term 'busier units' is used to denote those units that, due to the number of anaesthetic interventions and/or other local factors, require higher levels of resources to deliver the necessary service.

Duty anaesthetist – the term ‘duty anaesthetist’ is used here to denote the anaesthetist who is the doctor immediately responsible for the provision of obstetric anaesthetic services during the duty period.

Lead anaesthetist – the autonomously practising anaesthetist who has overarching responsibility for the governance of the obstetric anaesthetic service in the organisation and oversees the provision of a service that meets the standards outlined in this chapter. Individuals should be fully supported by their clinical director and be provided with adequate time and resources to allow them to effectively undertake the lead role.

Immediately within five minutes.

Obstetric unit an NHS clinical location in which care is provided by a team, with obstetricians taking primary professional responsibility for women at high risk of complications during labour and birth. Midwives offer care to all pregnant women in an obstetric unit, whether or not they are considered at high or low risk, and take primary responsibility for those with straightforward pregnancies during labour and birth. Diagnostic and treatment medical services, including obstetric, neonatal and anaesthetic care, are available on site 24 hours a day.164

Obstetrician-led care care in labour where the obstetrician is responsible for the pregnant woman’s care. This should only be provided in an obstetric-led unit in a hospital. Much of the their care will still be provided by a midwife.165,166

Obstetric team the term ‘obstetric team’ is used here to denote all the members of the multidisciplinary team that work in the maternity unit167

Session – a session typically describes a notional half day. Traditionally, this would have been confined to mornings or afternoons but, increasingly, hospitals are expanding the working day to accommodate a third evening session.

Supervising anaesthetist – denotes the autonomously practising anaesthetist with overall clinical responsibility for the delivery of obstetric anaesthetic services during the duty period.
