title: Issues of consent for regional analgesia in labour: a survey of obstetric anaesthetists.
abstract: Anaesthetists are legally obliged to obtain consent and inform patients of material risks prior to administering regional analgesia in labour. We surveyed consultant members of the Australian and New Zealand College of Anaesthetists with a special interest in obstetric anaesthesia, in order to identify and compare which risks of regional analgesia they report discussing with women prior to and during labour. We also asked about obstetric anaesthetists' beliefs about informed consent, the type of consent obtained and its documentation. Of 542 questionnaires distributed, 291 responses (54%) were suitable for analysis. The five most commonly discussed risks were post dural puncture headache, block failure, permanent neurological injury, temporary leg weakness and hypotension. Obstetric anaesthetists reported discussing a mean of 8.0 (SD 3.8) and 10 (SD 3.8) risks in the labour and antenatal settings respectively. Nearly 20% of respondents did not rank post dural puncture headache among their top five most important risks for discussion. Seventy percent of respondents indicated that they believe active labour inhibits a woman's ability to give 'fully informed consent'. Over 80% of respondents obtain verbal consent and 57 (20%) have no record of the consent or its discussion. Obstetric anaesthetists reported making a considerable effort to inform patients of risks prior to the provision of regional analgesia in labour. Verbal consent may be appropriate for labouring women, using standardized forms that serve as a reminder of the risks, and a record of the discussion. Consensus is required as to what are the levels of risk from regional analgesia in labour.
