Use of adrenaline in obstetric analgesia.

A questionnaire on the use of adrenaline in obstetric analgesia was completed by 87 obstetric anaesthetists: 71% of consultants in teaching hospitals were prepared to use adrenaline mixed with local anaesthetics compared with 33% of consultants in district hospitals; they had a similar duration of obstetric anaesthetic experience. Test doses containing adrenaline were not commonly used in labour, but were more often used prior to elective Caesarean section. Adrenaline was used with either lignocaine or bupivacaine; few consultants used both solutions. Contraindications to the use of adrenaline in the nonuser group were in decreasing order of rank: neurological damage, pregnancy-induced hypertension, stenotic valvular heart disease, sickle cell disease or trait of fetal distress. Overall, the contraindications related to the systemic absorption of adrenaline were most common.
