Surgical site infections (SSI) cause excess morbidity and mortality in modern surgery. Several different approaches to reduce the incidence of SSI have been investigated with variable results.
This is to our knowledge the first systematic randomized evaluation in patients undergoing laparotomy in visceral surgery to clarify whether widely used subcutaneous drains (Redon) affect wound infection as the primary outcome measure.
In 200 patients, we were unable to show a statistically significant impact on the postoperative healing process in patients with the full variety of abdominal surgical interventions. Overall, we observed surgical site infection in 9.5% of all patients (n = 19), of these n = 9 (47.4%) were in the control group without a drain, and 10 (52.6%) were in the experimental group with a Redon drain (not significant).
As this study could not demonstrate a reduction of SSI by the use of Redon drains, there is no indication for prophylactic subcutaneous suction drains after laparotomy.
手术部位感染（SSI）会给现代外科手术带来过多的发病率和死亡率。已经研究了几种不同的方法来降低 SSI 的发生率，但结果各不相同。
这是我们所知的首例针对内脏外科剖腹手术患者的系统随机评估，旨在明确广泛使用的皮下引流管（雷顿管）是否会影响伤口感染作为主要观察指标。
在 200 名患者中，我们无法证明在接受各种腹部外科干预的患者的术后愈合过程中具有统计学意义的影响。总体而言，我们观察到所有患者中有 9.5%（n=19）发生了手术部位感染，其中 n=9（47.4%）在无引流管的对照组中，n=10（52.6%）在有雷顿引流管的实验组中（无显著差异）。
由于本研究未能证明使用雷顿引流管可降低 SSI 的发生率，因此剖腹术后不建议预防性使用皮下抽吸引流管。
