Anaesthesia for Caesarean section. The potential for regional block.
This study of the obstetric and anaesthetic circumstances relating to 100 consecutive Caesarean sections under general anaesthesia suggests that the general anaesthesia rate for Caesarean section could be reduced from the present 37 to 27% by making maximum use of epidural block and to 16% by using subarachnoid block in addition. The need for general anaesthesia on account of urgency to deliver can be greatly reduced by the administration of epidural analgesia during labour in patients identified as being more likely than average to require Caesarean section, and by the use of subarachnoid block when the need for section arises unexpectantly. Patients' objections to undergoing Caesarean section while conscious were analysed, and suggestions are made for minimising the number of patients who decline. Technical problems with blocks may sometimes be overcome without resort to general anaesthesia, while patients at risk from haemorrhage or coagulopathy will continue to require general anaesthesia.
