Inverse Ratio Ventilation on Bariatric Operation

Not Applicable

Completed

• Conditions: Hypoxia
• Interventions: Other: inverse ratio ventilation

• Registration Number: NCT01922401
• Lead Sponsor: Gachon University Gil Medical Center

Brief Summary

for evaluating inverse ratio ventilation of laparoscopic bariatric surgery

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
inverse ratio ventilation	inverse ratio ventilation	in one group change the I:E ratio during pneumoperitoneum 1:2-1:2-2:1

Primary Outcome Measures

Name	Time	Method
Arterial oxygenation (PaO2)	baseline PaO2-2hour after pneumoperitoneum	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
