Review Meta Analysis
High-concentration oxygen and surgical site infections in abdominal surgery: a meta-analysis.
There has been recent interest in using high-concentration oxygen to prevent surgical site infections (SSIs). Previous meta-analyses in this area have produced conflicting results. With the publication of 2 new randomized controlled trials (RCTs) that were not included in previous meta-analyses, an updated review is warranted. Our objective was to perform a meta-analysis on RCTs comparing high- and low- concentration oxygen in adults undergoing open abdominal surgery. ⋯ There is moderate evidence that high-concentration oxygen does not reduce SSIs in adults undergoing open abdominal surgery.
