The study aims to systematically examine the efficacy of dermal regeneration templates (DRTs) in comparison to split thickness skin grafting (STSG) in the management of acute burn injuries post-excision and debridement.
Systematic literature search was conducted by two independent reviewers from the following databases: MEDLINE, EMBASE and Cochrane Library with selection criteria set a priori. Only randomized controlled trials (RCTs) were included. Main outcomes extracted were percent of STSG take, infection rate and scar quality.
Seven studies were included. Three of the seven studies reported no significant difference in STSG take between burn wounds treated with dermal substitute and or STSG only. Three of the seven studies reported either low rates of infection or no significant difference in infection rates between dermal substitute and control. Four of the seven studies reported no significant difference in scar quality. Statistical pooling of data was not performed due to heterogeneity of the studies.
Current RCTs available are generally of small sample size with poor methodological reporting. Given the results of more recent RCTs, the risk associated with DRTs is low and it can be a useful alternative for immediate wound coverage post-burn excision. However, there is still no strong evidence to support that DRTs have significant impact on scaring.
本研究旨在系统地比较真皮再生模板(DRTs)与中厚皮片移植(STSG)在急性烧伤创面切除和清创术后处理中的疗效。
由两名独立评审员从以下数据库进行系统文献检索:MEDLINE、EMBASE和Cochrane图书馆,预先设定选择标准。仅纳入随机对照试验(RCTs)。提取的主要结局指标为中厚皮片移植成功率、感染率和瘢痕质量。
共纳入7项研究。7项研究中的3项报告称,使用真皮替代物治疗的烧伤创面与仅使用中厚皮片移植的创面在中厚皮片移植成功率方面无显著差异。7项研究中的3项报告称,真皮替代物组的感染率较低,或与对照组在感染率方面无显著差异。7项研究中的4项报告称,瘢痕质量无显著差异。由于研究的异质性,未进行数据的统计合并。
目前可用的随机对照试验样本量普遍较小,方法学报告质量较差。鉴于近期随机对照试验的结果,与真皮再生模板相关的风险较低,它可作为烧伤创面切除后即时创面覆盖的一种有用替代方法。然而,仍没有强有力的证据支持真皮再生模板对瘢痕形成有显著影响。
