双管喉罩与标准型喉罩用于妇科腹腔镜麻醉的比较

Comparison of LMA-ProSeal with LMA-Classic used in gynaecological laparoscope

目的比较双管喉罩(PLM)与标准型喉罩(CLM)用于妇科腹腔镜麻醉的实用性和安全性。方法100例妇科腹腔镜择期患者随机分成PLM组(P组)和CLM组(L组),每组50例。观察两组插入时间与成功率、肺通气情况、气道密封压值、胃胀气情况、注意反流、拔管情况和术后有无咽痛。结果P组平均置入时间明显长于L组(P<0.05),P组首次置入成功率明显高于L组(P<0.05)。P组肺通气满意度、气道密封压明显优于L组(P<0.05);结论与CLM相比,PLM增加插入成功率,能最大程度减少反流误吸风险,改善气道密封,减少漏气,术后并发症少。

Objective To compare the practicability and the security of LMA-ProSeal（PLM） with that of the LMA-Classic （CLM） used in gynaecological laparoscope . Methods One hundred patients undergoing selective operation under gynaecological laparoscope were randomized to two groups PLM（P） and CLM（L） with 50 cases each. The average time and success rate of tracheal intubation, lung ventilation satisfaction, airway seal pressure, flatulence, backflow, extubation response and post-operational sore throat were recorded. Results The average time of tracheal intubation in group P was 10 s longer than that in group L. The success rate of first attempt of intubation in group P was significantly highter than that in group L. Lung ventilation satisfaction and airway seal pressure in group P was better than those in group L （P〈0. 05）. Conclusion Compaered to CLM, PLM has some advantages of increasing success rate of intubation reducing aspiration risk and improving airway seal.
