Neuromuscular blocking drugs (NMBDs) are the most common cause of intraoperative anaphylaxis in Western Australia. Differences in the rates of anaphylaxis between individual agents have been surmised in the past, but not proven, and are an important consideration if agents are otherwise equivalent. ⋯ Rocuronium has a higher rate of IgE-mediated anaphylaxis compared with vecuronium, a result that is statistically significant and clinically important. Cisatracurium had the lowest rate of cross-reactivity in patients who had previously suffered anaphylaxis to rocuronium or vecuronium.

Anaphylactic reactions during anaesthesia: neuromuscular blocking agents, latex and antibiotics.
A French team investigated hypersensitivity reactions that occurred during locoregional or general anaesthesia over an 8-year period. They estimated that the incidence of anaphylactic reactions was about 1 per 10 000 anaesthetic procedures. Among the 1816 reports of anaphylactic reactions, the most commonly implicated drugs were neuromuscular blocking agents (1067 cases), latex (361 cases), and antibiotics (236 cases). ⋯ Most reactions in children were due to latex, followed by neuromuscular blocking agents and antibiotics. In practice, exposure to latex devices should be minimised, or simply avoided when possible. A history of sensitization to substances sharing allergenic sites with neuromuscular blocking agents should be investigated, and measures should be taken to protect patients.

Residual neuromuscular blockade affects postoperative pulmonary function.
Residual neuromuscular blockade (RNMB) is known to be associated with respiratory complications in the postoperative period after muscle relaxant usage. The authors hypothesized that RNMB causes reductions in pulmonary function test (PFT) parameters in the immediate postoperative period. ⋯ RNMB results in reductions in forced vital capacity and peak expiratory flow in the immediate postoperative period indicating impaired respiratory muscle function.
