High Perioperative Oxygen Fraction for Abdominal Surgery and Risk of Surgical Site Infection

JAMA. 2010;303(6):515. doi:10.1001/jama.2010.90

To the Editor: In their randomized controlled trial, Dr Meyhoff and colleagues1 reported that administration of 80% oxygen compared with 30% oxygen during and for 2 hours after abdominal surgery did not result in a difference in risk of surgical site infection. This conclusion conflicts with those reported in previous large studies,25 a difference that might reflect unrecognized confounding.
