Supplemental Postoperative Oxygen and Wound Infection in Morbidly Obese Patients

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00315822

Brief Summary:
The investigators propose to test the hypothesis that the incidence of major complications related to infection or inadequate healing is reduced in morbidly obese patients given 80% inspired oxygen during, and for 12-18 hours after, surgery compared with patients given 80% oxygen only during surgery. The primary outcome will be a composite of major complications plausibly related to infection or healing.

Arm Intervention/treatment
Placebo Comparator: 30% oxygen
Subjects undergoing surgery will receive routine administration of oxygen
Other: 30% oxygen
Subjects undergoing surgery will receive routine administration of oxygen

Active Comparator: 80% oxygen
