Surgical-site infections (SSIs) increase morbidity and mortality in surgical patients and represent an economic burden to healthcare systems. Experiments have shown that triclosan-coated sutures (TCS) are beneficial in the prevention of SSI, although the results from individual randomized controlled trials (RCTs) are inconclusive. A meta-analysis of available RCTs was performed to evaluate the efficacy of TCS in the prevention of SSI.
A systematic search of PubMed, Embase, MEDLINE, Web of Science(®), the Cochrane Central Register of Controlled Trials and internet-based trial registries for RCTs comparing the effect of TCS and conventional uncoated sutures on SSIs was conducted until June 2012. The primary outcome investigated was the incidence of SSI. Pooled relative risks with 95 per cent confidence interval (c.i.) were estimated with RevMan 5.1.6.
Seventeen RCTs involving 3720 participants were included. No heterogeneity of statistical significance across studies was observed. TCS showed a significant advantage in reducing the rate of SSI by 30 per cent (relative risk 0·70, 95 per cent c.i. 0·57 to 0·85; P < 0·001). Subgroup analyses revealed consistent results in favour of TCS in adult patients, abdominal procedures, and clean or clean-contaminated surgical wounds.
TCS demonstrated a significant beneficial effect in the prevention of SSI after surgery.
手术部位感染(SSI)会增加外科患者的发病率和死亡率,并给医疗保健系统带来经济负担。实验表明,三氯生涂层缝线(TCS)有益于预防 SSI,尽管个别随机对照试验(RCT)的结果尚无定论。我们对现有的 RCT 进行了荟萃分析,以评估 TCS 在预防 SSI 中的效果。
系统检索了 PubMed、Embase、MEDLINE、Web of Science(®)、Cochrane 中央对照试验注册库和互联网临床试验注册库,以查找比较 TCS 和常规未涂层缝线对 SSI 影响的 RCT,检索时间截至 2012 年 6 月。主要结局是 SSI 的发生率。采用 RevMan 5.1.6 软件计算合并相对风险(RR)及其 95%可信区间(95%CI)。
纳入了 17 项 RCT 共计 3720 名患者。各研究间无统计学意义的异质性。TCS 显著降低了 30%的 SSI 发生率(RR 0·70,95%CI 0·57 至 0·85;P<0·001)。亚组分析显示,TCS 对成人患者、腹部手术以及清洁或清洁污染手术伤口均有一致的有益作用。
TCS 在预防手术后 SSI 方面具有显著的有益效果。
