Background: The rationale for hyperoxygenation in controlling surgical site infection (SSI) has been described in many studies yet has not been defined clearly. Some studies in colorectal surgery have reported beneficial effects, whereas studies in gynecologic surgery have reported either no effect or a deleterious effect. This study assessed the effectiveness of hyperoxygenation on the reduction of SSI in patients undergoing emergency abdominal surgery.

围手术期高氧合对急诊腹部手术患者手术部位感染的影响：一项随机对照试验

背景：在许多研究中已经描述了控制手术部位感染 (SSI) 的过度氧合的基本原理，但尚未明确定义。一些结直肠手术研究报告了有益效果，而妇科手术研究报告了无效果或有害效果。本研究评估了高氧合对减少急诊腹部手术患者 SSI 的有效性。
