Choice of anaesthesia for category‐1 caesarean section in women with anticipated difficult tracheal intubation: the use of decision analysis

Summary A predicted difficult airway is sometimes considered a contra‐indication to rapid sequence induction of general anaesthesia, even in an urgent case such as a category‐1 caesarean section for fetal distress. However, formally assessing the risk is difficult because of the rarity and urgency of such cases. We have used decision analysis to quantify the time taken to establish anaesthesia, and probability of failure, of three possible anaesthetic methods, based on a systematic review of the literature. We considered rapid sequence induction of general anaesthesia with videolaryngoscopy, awake fibreoptic intubation and rapid spinal anaesthesia. Our results show a shorter mean (95% CI) time to induction of 100 (87–114) s using rapid sequence induction compared with 9 (7–11) min for awake fibreoptic intubation (p
