title: [Auditing of drug use practices in anesthesia].
abstract: OBJECTIVE
  Internal pharmaceutical practice guidelines were produced in a department of anaesthesia of a University hospital in 1995, after a preliminary evaluation showing controversial and expensive practices. After approval, these recommendations were circulated to all members of the department. Phase I of this study was started 18 months later, to evaluate the compliance of anaesthetists with these guidelines.
  
  
  METHODS
  Prospective survey.
  
  
  METHODS
  An audit was performed by a research assistant pharmacist, previously trained, who compared anaesthetic agents and fresh gas flows used during anaesthetics with those recommended in the internal guidelines.
  
  
  RESULTS
  Implementation of guidelines was observed in more than 90% of cases for all agents studied, except for non-depolarizing neuromuscular relaxants. Relaxants of intermediate duration were used in 52% of cases with an expected surgery duration of more than 90 min, in opposition to the guidelines stating that pancuronium should have been administered in such circumstances. These results were presented and discussed. Slight changes in the guidelines (especially concerning monitoring of neuromuscular blockade) were made and evaluated again, using the same method (Phase II). A small but significant improvement was seen with induction agents (use of propofol in non-approved situations: 5 versus 0%, P = 0.03), while a non significant trend toward better implementation of guidelines was seen with non-depolarizing agents (use of pancuronium in surgery of expected duration > 90 min: phase I vs phase II = 47 vs 52%, NS; use of pancuronium in surgery of expected duration < 90 min: phase I vs phase II = 3.5 vs 0%, NS).
  
  
  CONCLUSIONS
  This study suggests that implementation of internal guidelines is easy when clinical indications of the agents are not controversial.
