伤口湿性愈合的新理念

湿性愈合的概念是近几年来，国外新型敷料不断进入医疗市场，并为伤口治疗、换药提出一个关于伤口愈合的新理念。同时为换药、伤口护理带来了新的措施和新的方法。更重要的是对传统的、常规的换药方法提出了挑战。     

湿性愈合疗法在腹部二期愈合手术切口中的应用

目的比较湿性与干性愈合疗法对腹部二期愈合手术切口的疗效。方法腹部手术后切口二期愈合患者60例,随机分为治疗组(31例)和对照组(29例)。治疗组采用湿性愈合疗法处理伤口,对照组采用常规方法换药。结果治疗组治愈率为83.9%,总有效率为96.8%,对照组治愈率为51.7%,总有效率为69.0%,两组比较有统计学差异(P0.05)。治疗组换药(6.8±2.0)次,明显少于对照组的(26.6±6.8)次(P0.05);治疗组治疗时间为(16.2±4.0)d,明显短于对照组的(28.5±7.2)d(P0.05)。结论湿性愈合疗法治疗时间短,换药次数少,治愈率及总有效率高,优于传统的干性愈合疗法,值得临床推广。

Moist Wound Healing with Occlusive Dressings: A Clinical Focus

The concept of moist wound healing, which is facilitated by the application of occlusive dressings, dates back to 1615 BC, and the technique is currently supported by a relatively large volume of data. It is clear that occlusive dressings are in many cases associated with more rapid reepithelialization, a reduced risk of infection, and more rapid wound healing than the alternatives. Nevertheless, many clinicians have been slow to accept this therapeutic technique. This article traces the history of moist wound healing from its earliest inception, examines the theoretical mechanisms of its effect, and explores its advantages and disadvantages. It also reviews the literature supporting the use of occlusive dressings in a variety of wound settings and examines the possible reasons behind the apparent reluctance on the part of the medical community to accept a potentially valuable therapy.     

新型湿性敷料在高位肛瘘术后创面中的应用

为探讨新型湿性敷料联合应用对促进高位肛瘘术后创面愈合的疗效,将35例高位肛瘘手术患者随机分为治疗组（新型湿性敷料）和对照组（传统方法）,进行创面愈合疗效的比较。结果显示,治疗组在减轻创面疼痛、渗出及创面愈合率方面均明显优于对照组（P〈0．01）。结果表明,新型湿性敷料联合应用在肛瘘术后的创面,能较好地控制局部感染,促进肉芽组织增生,加速上皮生长,并能缩短创面愈合时间,具有临床应用价值。     

光动力疗法在皮肤创面愈合中的作用

光动力疗法（PDT）是一种物理疗法,其作用机制在于利用光、光敏剂及氧的互相作用,从而发挥治疗疾病的作用,逐渐广泛应用于肿瘤疾病、皮肤疾病的临床治疗中。皮肤伤口愈合的生理过程较为复杂,是一种动态化改变。正常情况下皮肤可以通过自我更新和分化来维持皮肤代谢,但皮肤发生创伤后,皮肤中剩余的扩展多能干细胞（EPSCs）被激活并产生更多的扩增细胞。当EPSCs受损,皮肤则失去了自我修复的功能。随着PDT在临床的应用,其可对受损皮肤组织进行重建,对于促进皮肤感染和非感染性伤口的愈合具有积极作用。本文对PDT在皮肤创伤愈合中的作用、机制及临床意义作一综述,以期为同类皮肤疾病的治疗提供一定参考依据。

Low-Level Laser Therapy for Wound Healing: Mechanism and Efficacy

BACKGROUND: Given the recent interest in light-emitting diode (LED) photomodulation and minimally invasive nonablative laser therapies, it is timely to investigate reports that low-level laser therapy (LLLT) may have utility in wound healing. OBJECTIVES: To critically evaluate reported in vitro models and in vivo animal and human studies and to assess the qualitative and quantitative sufficiency of evidence for the efficacy of LLLT in promoting wound healing. METHOD: Literature review, 1965 to 2003. RESULTS: In examining the effects of LLLT on cell cultures in vitro, some articles report an increase in cell proliferation and collagen production using specific and somewhat arbitrary laser settings with the helium neon (HeNe) and gallium arsenide lasers, but none of the available studies address the mechanism, whether photothermal, photochemical, or photomechanical, whereby LLLT may be exerting its effect. Some studies, especially those using HeNe lasers, report improvements in surgical wound healing in a rodent model; however, these results have not been duplicated in animals such as pigs, which have skin that more closely resembles that of humans. In humans, beneficial effects on superficial wound healing found in small case series have not been replicated in larger studies. CONCLUSION: To better understand the utility of LLLT in cutaneous wound healing, good clinical studies that correlate cellular effects and biologic processes are needed. Future studies should be well-controlled investigations with rational selection of lasers and treatment parameters. In the absence of such studies, the literature does not appear to support widespread use of LLLT in wound healing at this time. Although applications of high-energy (10-100 W) lasers are well established with significant supportive literature and widespread use, conflicting studies in the literature have limited low-level laser therapy (LLLT) use in the United States to investigational use only. Yet LLLT is used clinically in many other areas, including Canada, Europe, and Asia, for the treatment of various neurologic, chiropractic, dental, and dermatologic disorders. To understand this discrepancy, it is useful to review the studies on LLLT that have, to date, precluded Food and Drug Administration approval of many such technologies in the United States. The fundamental question is whether there is sufficient evidence to support the use of LLLT.
