AbstractC1-esterase inhibitor deficiency is a rare disorder of the complement system characterised by episodes of cutaneous and mucosal oedema. Life-threatening airway oedema can follow airway instrumentation or minor trauma. We describe the successful management of a 37-year-old primiparous woman with inherited C1-esterase inhibitor deficiency who was admitted at 38 weeks' gestation for elective caesarean section. Whilst undergoing general anaesthesia 18 months previously she had experienced facial and pharyngeal oedema despite prophylaxis (one unit of fresh frozen plasma). On this occasion she underwent elective caesarean section following intrathecal anaesthesia with 0.5% hyperbaric bupivacaine 2 mL and diamorphine 300 microg. Cardiovascular stability was ensured using glycopyrolate and intravenous Hartmann's solution 2 L; a live female infant was delivered successfully. There were no peri- or postoperative complications. Regional anaesthesia is the safest method for providing surgical anaesthesia in the obstetric patient. We believe elective caesarean section under regional anaesthesia should be considered if there are predicted difficulties with vaginal delivery.
