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 olfactory position in patients undergoing general anesthesia for tracheal intubation. Methods 140 patients undergoing laparoscopic cholecystectomy in our hospital were divided into observation group (70 cases) and control group (70 cases) by random number table. The patients in the control group were given conventional supine position. The observation group was given the sniffing position. The tracheal intubation time, Cormack-Lehane throat classification, complications and vital signs were compared between the two groups. Results The tracheal intubation time and complication rate in the observation group were lower than those in the control group (P <0.05). The success rate of the first intubation in the observation group was higher than that in the control group (P <0.05), and Cormack-Lehane laryngeal classification was superior to the control group P <0.05). The heart rate and mean arterial pressure in the observation group after tracheal intubation were superior to those in the control group (P <0.05). Conclusions The tracheal intubation of patients with surgery using sniffing bit, can improve the success rate of the first intubation, reduce nausea and vomiting, throat discomfort, and maintain hemodynamic stability.
