Brief Summary

Supplemental perioperative oxygen has been reported to halve or double the risk of surgical wound infection. We tested the hypothesis that supplemental oxygen reduces infection risk following colorectal surgery. Colorectal surgery patients (n=300) were randomly assigned to 30% or 80% FiO2 intraoperatively and 6 hours postoperatively. Wound infections were diagnosed by blinded investigators using Centers for Disease Control criteria. Baseline patient characteristics, anesthetic management, and potential confounding factors were recorded. Wound infection rates were compared with chi-square analysis. Logistic regression identified the contribution of potential confounding factors. Surgical wound infection occurred in 24.4% of patients receiving 30% oxygen, but only 14.9% of those receiving 80% oxygen (P\<0.039). According to logistic regression, the relative risk of infection in patients given supplemental oxygen was 0.46 (P=0.035). Supplemental inspired oxygen reduced wound infection risk by roughly a factor of two. We thus recommend that supplemental oxygen be provided to patients undergoing colorectal surgery.

Study Arms (2)

80% perioperative oxygen

ACTIVE COMPARATOR

Perioperative supplemental oxygen: Patients were randomly assigned to 80% fraction of inspired oxygen (FIO2) intraoperatively and for 6 hours after surgery. Anesthetic treatment and antibiotic administration were standardized.

Procedure: Perioperative supplemental oxygen

30% perioperative oxygen

PLACEBO COMPARATOR

Standard oxygen: Patients were randomly assigned to 30% fraction of inspired oxygen (FIO2) intraoperatively and for 6 hours after surgery. Anesthetic treatment and antibiotic administration were standardized.

Procedure: Standard oxygen

Interventions

Patients were assigned to 80% fraction of inspired oxygen (FIO2) intraoperatively and for 6 hours after surgery. Anesthetic treatment and antibiotic administration were standardized.

80% perioperative oxygen

Patients were assigned to 30% fraction of inspired oxygen (FIO2) intraoperatively and for 6 hours after surgery. Anesthetic treatment and antibiotic administration were standardized.

30% perioperative oxygen
