摘要【目的】探讨不同充气量双管喉罩在妇科腹腔镜手术麻醉中的效果和安全性。【方法】选择2010年6月至2013年6月来本院接受妇科腹腔镜手术的121例患者作为研究对象，按囊内充气容量不同随机分为A组（30例）、B组（30例）、C组（30例）和D组（31例）。采用全身麻醉诱导，将4号喉罩套囊内气体放尽后置入患者喉部。向四组患者喉罩套囊充入不同容量气体：A组12mL，B组18mL，C组24mL，D组30mL。记录各组患者喉罩置入前后的血液动力学变化以及置入喉罩后的囊内压与并发症的关系。【结果】四组患者在置入不同充气量的喉罩前后血流动力学指标变化两两比较差异无统计学意义（P ＞0．05），围术期并发症比较显示，A组患者并发症明显低于B组、C组和D组，差异具有统计学意义（ P ＜0．05）；四组患者喉罩置入后套囊内压比较显示，A组囊内压最低，且4组间两两比较，差异均具有统计学意义（ P ＜0．05）。【结论】在妇科腹腔镜麻醉中使用充气12 m L的4号喉罩，能够显著减少围术期并发症的发生率，值得临床借鉴使用。
Abstract：To explore the efficacy and safety of different inflated double-barreled laryngeal mask in gynecological laparoscopic anesthesia .[Methods] Totally 121 patients undergoing gynecological lapa-roscopy in our hospital from June 2010 to June 2013 were enrolled in the study .According to different intra-cuff inflation capacity in cyst ,all patients were randomly divided into group A ( n =30) ,group B( n =30) , group C( n = 30) and group D( n = 31) .After the induction of general anesthesia ,NO .4 laryngeal masks without gas were intubated in laryngeal of patients .The mask cuffs of patients in 4 groups were filled with dif-ferent capacity of gases(group A with 12ml ,group B with 18ml ,group C with 24ml and group D with 30ml) . The hemodynamic changes and the relationship between intra-cuff pressure(ICP) and complications after the intubation of laryngeal mask in 4 groups were recorded .[Results]There was no significant difference in hemo-dynamic changes among 4 groups after filled with different capacity of gases ( P > 0 .05) .The incidence of perioperative complications in group A were lower than that in group B ,C and D ,and there was significant difference( P <0 .05) .By comparison of ICP among 4 groups ,ICP of group A was the lowest ,and there was significant difference between 4 groups( P < 0 .05) .[Conclusion]The use of NO .4 inflated laryngeal mask with 12ml gases in gynecological laparoscopic anesthesia can reduce the incidence of perioperative complications markedly .Therefore ,it is worthy of clinical application .
