目的 探讨嗅物位在全身麻醉气管插管手术患者中的应用效果.方法 选择我院腹腔镜胆囊切除全身麻醉手术患者140例,采用随机数字表法分为观察组和对照组各70例.对照组患者采取常规去枕仰卧位,观察组采取嗅物位,观察比较2组手术患者的气管插管时间、Cormack-Lehane喉头分级、并发症及生命体征.结果 观察组气管插管时间及并发症发生率低于对照组(P<0.05),观察组首次气管插管成功率高于对照组(P<0.05),Cormack-Lehane喉头分级优于对照组(P<0.05),观察组气管插管后心率和平均动脉压优于对照组(P<0.05).结论 手术患者气管插管时采用嗅物位,能提高首次气管插管成功率,降低恶心呕吐、咽喉部不适发生,并维持血流动力学稳定.

Objective To investigate the effect of sniffing position on endotracheal intubation under general anesthesia operational patients.Methods A total of 140 patients with laparoscopic cholecystectomy were divided into the observation group and the control gro
