An unusual case of sudden desaturation following induction of anaesthesia for caesarean section.
In the following case report an episode of sudden and rapid desaturation, occurring soon after induction of anaesthesia in a fit preoxygenated obstetric patient, resulted from the use of a Manley minute volume divider which had become purged with nitrous oxide.

A survey of airway management during induction of general anaesthesia in obstetrics: are the recommendations in the confidential enquiries into maternal deaths being implemented?
Recommendations were made in the last two triennial reports on maternal deaths regarding airway management prior to obstetric general anaesthesia. Forty-four hospitals were surveyed to determine departmental practice. Our survey suggests that obstetric anaesthetic practice varies widely between departments and several of the recommendations in the above reports have yet to be implemented.

Spinal anaesthesia for caesarean section following epidural analgesia in labour: a relative contraindication.
Three cases are described in which epidural analgesia was performed during labour using an infusion of bupivacaine 0.125-0.25%. When, in all 3 cases, caesarean section was required for failure to progress, hyperbaric bupivacaine was given in doses of 10 mg, 12.5 mg and 15 mg respectively. Within 2-4 min all 3 patients had a high block, complained of difficulty in breathing and subsequently developed apnoea. ⋯ All three mothers remain in good health and do not regret having had spinal anaesthesia for caesarean section. In contrast to previously reported cases of high spinal anaesthesia following unsuccessful epidural anaesthesia for caesarean section, this report describes 3 cases of high spinal following the administration of spinal anaesthesia upon an ongoing epidural infusion of local anaesthetic during labour. As no guidelines are available as to the recommended dose of spinal anaesthetic under such circumstances and, in view of the several case reports describing a similar complication under different circumstances, we suggest that spinal anaesthesia is contraindicated upon ongoing epidural analgesia or following a failed epidural.
