A national survey of atropine use by Australian anaesthetists.

All Fellows of the Faculty of Anaesthetists, Royal Australasian College of Surgeons (now Australian and New Zealand College of Anaesthetists) were surveyed by mail regarding their use of prophylactic atropine. They were asked whether their usual practice was to give atropine for the following indications: premedication, induction of anaesthesia, intubation of the trachea, one dose of suxamethonium, a second dose of suxamethonium, halothane anaesthesia, oropharyngeal surgery, bronchoscopy and eye surgery. For each indication they were asked for details regarding their practice concerning neonates, infants, children and adults. The large response rate of 86% of Fellows returning a survey form ensured that the survey was representative of Australian anaesthetic practice. Results indicate a wide variation in practice regarding the prophylactic use of atropine, with neonates, infants and children more likely to receive prophylactic atropine than adults. The majority do not give prophylactic atropine as premedication, but may give it in the younger age groups at induction, and many (67%) only give it if they are to administer suxamethonium to a child. The only indication for which a convincing majority (> 80%) of anaesthetists agreed that prophylactic atropine should be given was when a repeated dose of suxamethonium was to be given to neonates, infants or children. A large proportion of anaesthetists (> 80%) agreed that atropine is not necessary prior to halothane anaesthesia in all age groups, nor as premedication, at induction, at intubation, prior to oropharyngeal surgery or prior to eye surgery in adults. These results were compared with the practice at a major paediatric hospital where the practice is not to use routine prophylactic atropine.
