Failed tracheal intubation in obstetrics: A 6-year review in a UK region

Abstract

In the South Thames (West) region of the United Kingdom, during a 6-year period from 1993 to 1998, there was a significant increase in the Caesarean section rate accompanied by a significant decrease in the use of general anaesthesia for operative delivery. During this time, there were 36 failed tracheal intubations occurring in 8970 obstetric general anaesthetics (incidence 1/249). There was no significant difference in the incidence of failed tracheal intubation in each of the six years. In 24 of the 26 cases for which the patients' notes could be examined, there was either no recording of preoperative assessment, a failure to follow an accepted protocol for failed tracheal intubation, or no follow-up.
