Surgical wounds that become infected are often debrided because clinicians believe that removal of this necrotic or infected tissue will expedite wound healing. There are numerous methods available but no consensus on which one is most effective for surgical wounds.
To determine the effect of different methods of debridement on the rate of debridement and healing of surgical wounds.
In March 2013, for this third update, we searched the Cochrane Wounds Group Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL.
We included randomised controlled trials (RCTs) with outcomes including at least one of the following: time to complete debridement or time to complete healing.
Two review authors independently reviewed the abstracts and titles obtained from the search, extracted data independently using a standardised extraction sheet and independently assessed methodological quality. One review author was involved in all stages of the data collection and extraction process, thus ensuring continuity.
Five RCTs (159 participants) were eligible for inclusion; all compared treatments for infected surgical wounds and reported time required to achieve a clean wound bed (complete debridement). One trial compared an enzymatic agent (streptokinase/streptodornase) with saline-soaked dressings. Four trials compared the effectiveness of dextranomer beads or paste with other products (different comparator in each trial) to achieve complete debridement. Meta-analysis was not possible due to the unique comparisons within each trial. One trial reported that dextranomer achieved a clean wound bed significantly more quickly than Eusol, and one trial comparing enzymatic debridement with saline-soaked dressings reported that the enzyme-treated wounds were cleaned more quickly. However, methodological quality was poor in these two trials.
AUTHORS' CONCLUSIONS: There is a lack of large, high-quality published RCTs evaluating debridement per se, or comparing different methods of debridement for surgical wounds, to guide clinical decision-making.
手术伤口发生感染时通常会进行清创,因为临床医生认为清除这些坏死或感染组织将加快伤口愈合。现有多种方法,但对于哪种方法对手术伤口最有效尚无共识。
确定不同清创方法对手术伤口清创率和愈合率的影响。
2013年3月,为进行本次第三次更新,我们检索了Cochrane伤口小组专业注册库;Cochrane对照试验中央注册库(CENTRAL)(Cochrane图书馆);Ovid MEDLINE;Ovid MEDLINE(在研及其他非索引引文);Ovid EMBASE;以及EBSCO CINAHL。
我们纳入了随机对照试验(RCT),其结局包括以下至少一项:完成清创的时间或完成愈合的时间。
两位综述作者独立审查检索获得的摘要和标题,使用标准化提取表独立提取数据,并独立评估方法学质量。一位综述作者参与了数据收集和提取过程的所有阶段,从而确保了连续性。
五项RCT(159名参与者)符合纳入标准;所有研究均比较了感染手术伤口的治疗方法,并报告了实现清洁伤口床(完全清创)所需的时间。一项试验比较了一种酶制剂(链激酶/链道酶)与盐水浸湿敷料。四项试验比较了葡聚糖凝胶珠或糊剂与其他产品(每项试验中的比较对象不同)实现完全清创的有效性。由于每项试验中的比较独特,无法进行荟萃分析。一项试验报告称,葡聚糖凝胶比优琐尔更快实现清洁伤口床,一项比较酶清创与盐水浸湿敷料的试验报告称,酶处理的伤口清洁得更快。然而,这两项试验的方法学质量较差。
缺乏大型、高质量的已发表RCT来评估清创本身,或比较手术伤口的不同清创方法,以指导临床决策。
