喉罩通气全麻在腹腔镜胆囊切除手术中的应用

目的比较普通型喉罩（LMA）和气管插管（IT）在腹腔镜下胆囊切除术的应激反应，观察置人喉罩或气管导管的血流动力学变化，观察拔除喉罩或气管导管的血流动力学变化。方法选择拟行腹腔镜下胆囊切除手术患者60例，随机分为两组LMA组和IT组，LMA组为3或4号普通型喉罩IT组应用7．5或8．0号气管导管，记录插管前，插入后1min，拔除后1min的HR、SBP、DBP、结果插入拔除喉罩或气管导管时，IT组血流动力变化较LMA组明显（P〈0．05）。结论LMA全麻通气完全适用腹腔镜下胆囊切除术麻醉，应激反应小及并发症少。

Application of laryngeal mask airway ventilation anesthesia in laparoscopic cholecystectomy

Objective To comparie the stress response of laryngeal mask airway and endotracheal intu- bation during laparoseopic cholecystectomy , and observe hemodynamies change of placement and extraction of laryngeal mask airway or tracheal tube. Methods Sixty paitiens underment laparoseopic cholecystectomy were randomly assigned to two groups ： in group LMA 3 or d laryngeal mask airway were selected and in group IT 7.5 or 8. 0 tracheal tubes were applied. The HR,SBP and DBP before placement , 1 min after placement and 1 mira after extraction were recorded. Results Hemodynamics in group IT were obviously changed more than that in group LMA when placement extraction of laryngeal mask airway or tracheal tube （P 〈 0.05）. Conclusion LMA ventilation is fully applicable for the general anesthesia of laparoscopic cholecystectomy with small stress ro- sponse and less complications.
