We studied 60 children, aged 12 months to 8 yr, undergoing plastic surgery under general anaesthesia supplemented by regional anaesthesia. Patients were allocated randomly to have the laryngeal mask airway removed either on awakening or while anaesthetized. Subsequent observation of respiratory factors and oxygen saturation showed a significant difference between the groups for coughing (P < 0.001), with a greater incidence (17 of 33) in the awake group compared with those from whom the laryngeal mask airway was removed while anaesthetized (two of 27). There were no differences in the incidences of laryngospasm, desaturation (< 95%) and excess salivation between the groups. Removed of the laryngeal mask airway during deep anaesthesia reduced coughing in the immediate postoperative period.
我们研究了60名年龄在12个月至8岁之间、接受全身麻醉并辅以区域麻醉的整形手术儿童。患者被随机分配在苏醒时或麻醉状态下拔除喉罩气道。随后对呼吸因素和血氧饱和度的观察显示，两组在咳嗽方面存在显著差异（P < 0.001），苏醒组的发生率更高（33例中有17例），而在麻醉状态下拔除喉罩气道的组（27例中有2例）发生率较低。两组在喉痉挛、血氧饱和度降低（< 95%）和唾液过多的发生率方面没有差异。在深度麻醉期间拔除喉罩气道可减少术后即刻的咳嗽。
