Application of I-gel laryngeal mask airway in general anesthesia for laparoscopic surgery in neonates / 实用医学杂志

ABSTRACT

Objective To evaluate the effect of I-gel laryngeal mask airway in general anesthesia for lapa-roscopic surgery in neonates. Methods 40 neonates to undergo neonatal laparoscopic surgery were divided into I-gel laryngeal mask group(group I)and tracheal intubation group(group E)randomly,20 in each group. After the induction of anesthesia,I-gel laryngeal mask(size 4 each)was used for ventilation in Group I,and tracheal intu-bation with ID(3.0 or 3.5 mm)was performed for ventilation in group E. The two groups were compared in terms of intubation duration,success rate,the hemodynamic parameters like mean arterial pressure (MAP),heart rate (HR)and plus oxygen saturation(SpO2)at each time point.,the end-tidal carbon dioxide pressure(PETCO2), peak airway pressure (Ppeak),the airway sealing pressure (Pleak),and the postoperative complications. Results There was no significant difference between the two groups in the success rate of intubation (laryngeal mask). However,the duration required for laryngeal mask insertion in I group was significantly shorter than that in E group(P<0.01). MAP and HR were significantly lower than group E at the time point of T1(P<0.05). Pleak in group I was significantly lower than E group at the time points of T1 ~ T3(P < 0.01). The adverse reactions was significantly lower than that in the E group (P < 0.05). There was no reflux aspiration in both groups. Conclusion I-gel laryngeal mask airway can achieve the same effect as tracheal intubation does for general anes-thesia during laparoscopic surgery. It is easy to operate ,with high success rate and few complications.
