AbstractGuidelines about the use of neuromuscular blocking agents based on a national consensus conference have been published in 2000. A survey was carried out to assess adherence to these guidelines. An online questionnaire was designed from the different guidelines concerning the use of muscle relaxant for tracheal intubation and surgery, monitoring and antagonism of neuromuscular blockade. In addition, question about the knowledge of the pharmacodynamics of neuromuscular blocking agents were asked. Analysis concerned 1230 answers from senior anaesthetists. Tracheal intubation is facilitated by the use of a competitive agent or by succinylcholine by 58 and 8% of responders respectively. Atracurium and cisatracurium were most frequently used (49 and 44%, respectively). The duration of effect of an intubating dose of atracurium, vecuronium or rocuronium was estimated equal or below 60 min by more than half of responders, whereas that of cisatracurium was longer. Fifty-two or 74% of responders used neuromuscular monitoring, whether a single or repeated dose of muscle relaxant was administered. Antagonism of neuromuscular blockade was systematic, frequent, and episodic or excluded by 6, 26, 55 and 13% of responders, respectively. Monitoring and antagonism of neuromuscular blockade are underused despite the guidelines. Underestimation of the risk of postoperative residual curarization is linked to the underestimation of the duration of competitive neuromuscular blocking agents.
