Difficult and failed intubation in 3430 obstetric general anaesthetics*

P>A retrospective audit was performed of all obstetric general anaesthetics in our hospital over an 8 year period to determine the incidence of difficult and failed intubation. Data was collected from a number of sources to ensure accuracy. A total of 3430 rapid sequence anaesthetics were given. None of the patients had a failed or oesophageal intubation (95% CI, 0-1:1143). There were 23 difficult intubations (95% CI, 1:238-1:100). This was anticipated in nine cases, requiring awake fibreoptic intubation in three cases. Consultants or specialist registrars were involved in the management of all cases. We attribute the low incidence of airway complications to the above average rate of general anaesthesia in our hospital, senior cover and specialised anaesthetic operating department assistants.
