Application of Supreme laryngeal mask airway to the anesthesia of poster laparoscopic surgery with lateral position / 中国医师进修杂志

ABSTRACT

Objective To study the application of Supreme laryngeal mask airway (SLMA) with new type to the general anesthesia of lateral position. Methods Sixty patients with ASA Ⅰ - Ⅱ who planned to receive selective poster laparoscopic surgery were divided into SLMA group and general tracheal tuber (GTT) group with 30 cases of each by random digits table. After fast intravenous induction SLMA and GTT were intubated respectively to obtain artificial airway in each group. The time of intubation, efficiency of success,heart rate(HR), invasive blood pressure(IVBP),airway pressure,side effects were observed and recorded. Results The intubation time in SLMA group [(15.1 ±4.0) s] was shorter than that in GTT group [(30.5 ± 16.2) s] (t' =-5.05,P ＜0.05); there was no significant difference in efficiency of success between two groups [96.7%(29/30) vs. 76.7%(23/30),P＞ 0.05]. There was no significant difference in HR and IVBP during the time of intubation and extubation in SLMA group(P＞ 0.05), but not in GTT group(P＜0.05). There was no significant difference in the change of the airway pressure between two groups during the ventilation. There were no complications in two groups. Conclusions The time of SLMA intubation in the general anesthesia with lateral position is short. The effect of intubation and extubation to HR and blood pressure is light. The SLMA intubation is another way to set up safely artificial airway.
