Does High Intraoperative Inspired Oxygen Reduce Postoperative Arterial Oxygen Saturation?

Atelectasis Clinical Trial

Official title:
Does High Intraoperative Inspired Oxygen Reduce Postoperative Arterial Oxygen Saturation?

Clinical Trial Summary

The purpose of this study is to determine whether breathing high levels of oxygen during surgery affects oxygen levels after surgery. The second purpose of this study is to determine whether giving positive end expiratory pressure PEEP and high oxygen together affects patients oxygen levels after surgery.

Clinical Trial Description

This is a randomized, controlled, blinded trial in patients undergoing non-abdominal surgery of the effect of intraoperative increased inspired oxygen used (FiO2>0.9 vs. FiO2 = 0.3) on non-invasive oxygen saturation (pulse oximetry, SpO2) and amount of required supplemental oxygen in the post-anesthesia care unit (PACU); arterial oxygen partial pressure (PaO2) after 45 minutes in the PACU; room air SpO2 24 hours after surgery, and amount of supplemental oxygen required 24 hours after surgery. The purpose of the study is to determine whether absorption atelectasis induced by use of inspired oxygen concentrations in excess of 90% leads to a higher risk of hypoxemia, as evidenced by room air oxygen values and the need for supplemental oxygen. The objective of this study is to determine whether high inspired oxygen (>0.8), which has been demonstrated to reduce the risk of surgical site infection in patients undergoing colon surgery and other major surgical procedures has side effects that limit its use to prevent infection in lower risk operations.

There are four groups of intraoperative ventilation management in this study. Fi02 0.3 plus PEEP, Fi02 0.3 without PEEP, Fi02 greater than 0.9 plus PEEP 3 to 5 cm of water, Fi02 greater than 0.9 without PEEP. ;
