Use of the intubating laryngeal mask airway: are muscle relaxants necessary?

摘要: Background The intubating laryngeal mask airway (ILMA) is designed to facilitate blind tracheal intubation. effect of a muscle relaxant on the ability perform intubation through ILMA device has not been previously evaluated. This randomized, double-blind, placebo-controlled study was evaluate rocuronium, 0.2 or 0.4 mg/kg administered intravenously, success rate and incidence complications associated with ILMA-assisted Methods A total 75 healthy patients were induced propofol 2 fentanyl 1 microg/kg intravenously. After insertion device, either saline, rocuronium mg/kg, in volume 5 ml. At 90 s after administration drug, attempted using disposable polyvinyl tube. If unsuccessful, reusable silicone tube tried. In addition recording time number attempts required secure airway, during placement removal noted. Results Tracheal successful 76-96% patients. overall rates times similar all three treatment groups. high-dose group experienced less patient movement (8 vs. 28 48%) coughing (12 20 52%) than low-dose saline groups, respectively. Use also dose-related decrease requirement for supplemental bolus doses device. Conclusions did significantly improve performing ILMA. However, it produced decreases reduced difficulties
