Abstract:
A postal survey of obstetric anaesthetic units in the UK was conducted by questionnaire to gain information about current acid aspiration prophylaxis. Information regarding the delivery rate and the caesarean section rate under regional techniques was also requested. Replies were received from 202 obstetric anaesthetic units in the UK, a 75% response rate. The results are compared to similar surveys carried out in 1984 and 1988. Sodium citrate and the H(2) antagonist ranitidine remain the drugs most commonly used for acid aspiration prophylaxis. However, the number of departments carrying out routine prophylaxis for patients in active labour has fallen from 75% in 1988 to 57% in the current survey.
