Maggots Faster Than Scalpel in Wound Debridement
蛆虫应用于清创术中效果优于手术刀? December 19, 2011 — Maggot debridement therapy (MDT) appears to be more effective for wound debridement compared with conventional therapy, but only at 1 week; after that time, another type of dressing should be used, new research suggests. 2011-12-19——与常规疗法相比,在清理伤口上蛆虫清创术疗法(MDT)看起来更为有效,但是仅仅在1周时间内有效。最新的研究显示,之后应该使用另一种敷料。 Kristina Opletalovà, MD, from the Department of Dermatology, University of Caen, France, and colleagues published online December 19 in the Archives of Dermatology. 来自法国里昂大学皮肤科医务部的Kristina Opletalovà和她的同事12月19日在皮肤病档案馆上在线发表了他们的成果。 Medical maggots were approved by the US Food and Drug Administration as a medical device for wound debridement in 2004. According to the researchers, use of maggots in treating wounds is associated with effective wound debridement, antibacterial effects, and stimulation of wound healing. 2004年美国食品药品监督管理局允许将医用蛆虫作为医疗器械在伤口清创上使用。据研究人员说,使用蛆虫治疗伤口有效的清理了伤口,抑制细菌生长并且刺激伤口愈合。 However, they point out, "Relatively few clinical studies have been conducted and the results are not clear, partly owing to methodologic assessment problems." 但是他们指出,“相对来说,几乎没有进行过什么临床研究,结果也不是很明确,一定程度上是由于方法学验证的问题。” In the current prospective, randomized controlled, phase 3 clinical trial, the researchers sought to determine the efficacy of bagged larvae on wound debridement in comparison with conventional treatment. 以目前的视角来看,在3期临床试验中进行随机对照试验,研究人员试图确定与常规治疗相比,蛆虫清创术更为有效。 The primary objective was to compare the mean percentage of slough in wounds treated with MDT with that of conventional treatment at day 15. The study included 119 patients with a nonhealing, sloughy wound that was 40 cm2 or smaller and less than 2 cm deep. Patients also had an ankle brachial index of 0.8 or higher. 主要目的是在15天内比较常规治疗与蛆虫清创术中脱落的伤口死组织的平均百分比。这项研究中的119名病人身上都有未愈合、有腐肉伤口,面积为40cm2或更小,深度不超过2cm,同时患者具有0.8或更高的踝肱指数。 Treatment was administered during a 2-week hospital stay. Conventional treatment consisted of surgical debridement 3 times a week with a scalpel, with use of topical anesthesia. The MDT was administered using an enclosed dressing (Vitapad, BioMonde Laboratories) containing 80 sterile maggots. At discharge, a conventional dressing was applied, and patients were followed-up at day 30. 住院治疗时间为期2周。常规治疗包括每周3次在局部麻醉下使用清创手术用手术刀。蛆虫清创术治疗是使用含80个无菌蛆的封闭的敷料(Vitapad, BioMonde实验室)。出院时才用常规的换药方式,并在第30天对患者随访。 Debridement by MDT was significantly faster than surgical debridement during the first week of treatment, reaching the same level the control group reached at day 15. No benefit for MDT compared with conventional treatment in healing rates was observed. At day 8, 54.5% in the MDT group vs 66.5% in the control group (P = .04) had evidence of slough and wound healing. However, by day 15, the mean percentage of slough was 55.4% in the MDT group and 53.8% in the control group (P = .78). 在第一周蛆虫清创术的效果显著高于外科手术清创术,达到对照组在第15天的清创水平。在治愈率上,没有观察到蛆虫清创术较常规治疗更为有益。在第8天, 54.5%的MDT组与66.5%的对照组中(P =0.04)有伤口组织愈合的证据。但是在第15天,死组织脱落的百分比MTD组为55.4%,而对照组为53.8%(P =0.78). "Athough MDT shows no significant benefit at day 15 compared with conventional treatment, debridement by MDT is significantly faster and occurs during the first week of treatment," the researchers conclude. "Because there is no benefit in continuing the treatment after 1 week, another type of dressing should be used after 2 or 3 applications of MDT." “虽然与常规治疗相比,在第15天,蛆虫清创术没有明显的优势,但是在治疗的第一周,蛆虫清创术的治愈速度明显要更快。”研究者如是说,“由于在治疗1周后,蛆虫清创术已没有益处,所以在用蛆虫清创术治疗2到3次后就需要其他的敷料了。” Pain scores were similar and mild in both groups, although in contrast to conventional treatment, MDT was performed without topical anesthesia. 两组患者的疼痛评分相似且为轻度,虽然与常规治疗相比,蛆虫清创术没有使用局部麻醉。 According to the researchers, none of the patients were reticent about undergoing MDT. "[A] crawling sensation on the wound was rarely and almost equally noted in both groups, revealing that the sensation was subjective," Dr. Opletalovà and colleagues point out. 据研究人员介绍,接受蛆虫清创术的患者没有沉默寡言的人。Opletalovà博士和他的同事指出:“几乎没有蛆虫在伤口上蠕动的感觉,两组的记录也显示在感觉上他们大体相当,可见感觉是很主观的。” Two questions regarding MDT remain unanswered, the authors note. "Can debridement be improved using more maggots per dressing? If so, would these dressings be more painful? Further studies are needed to answer these questions." 作者指出,就蛆虫清创术而言还有两个问题尚未解决。“使用含更多蛆虫的敷料能提高清创的效果吗?如果可以,这种敷料是否会更痛苦?需要进一步的研究来解决这些问题。” The study was supported by grants from the Clinical Research Hospital Program and from the French Society of Dermatology. The authors have disclosed no relevant financial relationships. 这项研究由临床研究医院和法国皮肤科学会资助支持。 作者没表明相关的财务关系。 |
