Summary

The purpose of this study is to compare volume- and pressure- controlled ventilation with laryngeal mask airway Guardian in obese patients undergoing laparoscopic gynecologic surgery in terms of ventilatory efficacy, airway leak pressure (airway protection), ease-of-use and complications.

Detailed description

The Guardian Laryngeal Mask (Ultimate Medical Pty Ltd, Richmond, Vic, Australia) is a new silicone-based single-use extraglottic airway device that forms a seal with the glottis for ventilation and with the hypopharynx for airway protection, and provides a gastric drainage port. The aim of the following perspective, randomized, blind trial study id to compare how the volume-controlled ventilation and pressure-controlled ventilation modes using the Laryngeal Mask Guardian affect the pulmonary mechanics, the gas exchange and the cardiovascular responses particularly in obese patients undergoing gynecological laparoscopy.

Conditions

• Gynecologic Disease

Interventions

Type	Name	Description
PROCEDURE	tidal volume	In the volume controlled ventilation group using laryngeal mask airway Guardian,a tidal volume of 8-12ml/kg,respiratory rate12-16bpm.
PROCEDURE	peak airway pressure	In the pressure controlled ventilation group using laryngeal mask airway Guardian,a peak airway pressure that provides a tidal volume of 8-12ml/kg with an upper limit of 35 centimeter water column,respiratory rate12-16bpm.
