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 .
