Muscle weakness after muscle relaxants: an audit of clinical practice.

摘要: Residual muscle weakness after general anaesthesia, assessed using handgrip strength, was audited in a teaching hospital. The relationships between residual weakness, the use of relaxants and patient characteristics were examined. Handgrip strength measured preoperatively, one hour postoperatively day hand dynamometer 151 patients having anaesthesia. Forty-nine received no relaxant, 34 vecuronium 68 rocuronium. Patients managed by their anaesthetist according to that anaesthetist's clinical choice. All who neostigmine. One postoperatively, there decline 16% for relaxant group, 24% 29% degree groups unrelated age (P=0.89) but strongly influenced patient's sex. Almost all increased with found female patients. mean male either or rocuronium similar seen when had not been used (P=0. 40). showed marked decrease both (32% 34% respectively, combined P=0.01). These results suggest usual practice at our institution, are more likely have relaxants.
