Objective: To explore the safety, efficacy and side effect of Supreme laryngeal mask airway (LMA) used in gynecological laparoscopy.
Methods: From Oct. 2009 to Apr. 2010 in First Hospital of Peking University, 125 patients undergoing general anesthesia for elective gynecological laparoscopy were reviewed, 69 of which were dealt with Supreme LMA (S) and 56 with endotracheal tube (T). After anesthesia induction, changes of HR and MAP were observed during intubation and extubation. The peak inspiratory airway pressure (P(peak)) and P(ET)CO(2) were monitored. Relevant perioperative side effects were recorded.
Results: HR and MAP in group T were increased right after intubation and during extubation (P < 0.05), which were significantly decreased in group S (P < 0.01). P(peak) and P(ET)CO(2) were comparable in the two groups at all the time points (P > 0.05). There was no body movement or coughing at the time of intubation. Group S had less incidence of body movement, coughing and sore throat than group T during extubation (P < 0.05).
Conclusion: Supreme LMA can provide the same safe and effective ventilation as intubation and less stress response and side effects in gynecological laparoscopy.
