Overview

for evaluating inverse ratio ventilation of laparoscopic bariatric surgery

inverse ratio ventilation had been improve the oxygenation and respiratory mechanics during care of ARDS patients or during general anesthesia. We hypothized inverse ratio ventilatio could improve the oxygenation and respiratory mechanics on the obese patient also.

Primary Outcomes

Arterial oxygenation (PaO2)

sampling for arterial blood from arterial cannular weill be analysed 10 min after anesthetic induction, 20 min after pneurmoperitoneum (PP)with 1:2 of IE ratio, 20 min after after pneurmoperitoneum (PP)with 1:1 of IE ratio, after pneurmoperitoneum (PP)with 2:1 of IE ratio and end of operation

Time frame: baseline PaO2-2hour after pneumoperitoneum
