French obstetric anaesthetists and acid aspiration prophylaxis.

In 1988, a confidential postal questionnaire was prepared in order to assess the techniques used routinely in France for prophylaxis of aspiration of gastric contents in obstetrics. Of the 297 anaesthetists who responded, 81% (237) worked almost always and 19% worked occasionally in obstetric anaesthesia. Although obstetric anaesthesia is considered to carry a particular risk of aspiration of gastric contents (88.5% of responders), only 23% used in every case a complete set of prophylactic measures. The use of antacids has recently increased in France. Particulate antacids are no longer used whereas sodium citrate, cimetidine and ranitidine are prescribed by about 30%, 50% and 15% respectively of practitioners. Among the users of cricoid pressure, 52% were able to describe precisely the technique. Tracheal intubation is considered mandatory when general anaesthesia is performed for Caesarean section but not for uterine revision or instrumental manoeuvre. 74% of obstetric anaesthetists believe that regional anaesthesia is the best anaesthetic technique for Caesarean section. This survey has shown both positive results indicating that continuing medical education of French anaesthetists follows at least in part the 'state of the art' and insufficiencies indicating that training continues to be necessary to reduce the mortality related to aspiration of gastric contents.
