Comparison of Proseal Laryngeal Mask Airway with Endotracheal Intubation in General Anesthesia during Gynecologic Laparoscopic Surgery

Objective To explore the safety and efficacy of proseal laryngeal mask airway (PLMA) in general anesthesia during gynecologic laparoscopic procedure. Methods A total of 60 patients from January to May of 2009, ASA Ⅰ to Ⅱ, undergoing electively gynecologic laparoscopic surgery, were randomly assigned into PLMA group(group P)or endotracheal intubation group (group T). SBP, DBP, HR and SpO_2 were monitored on patients’arrival operating room,before and 5 min after PLMA insertion or endotracheal intubation, 5 min after PLMA or endotracheal extraction airway.Maximum pressure (P_max), vital volume (V_T), end tidal CO_2 (P_ETCO_2) were recorded before and after artificial pneumoperitoneum (APP). Results SBP, DBP and HR of group T were higher after endotracheal intubation than that of group P after PLMA insertion (P0.05). There were no significant differences in P_max, V_T and P_ETCO_2 between group T and group P before and during APP. There were no significant differences in successful rate of PLMA insertion or endotracheal intubation between the two groups,but the complications in group P were lower than that in group T after surgery (P0.05). Conclusion PLMA is safe and efficient in general anesthesia during gynecologic laparoscopic procedures.
