摘要:

文题释义:

控制性清创:气动/电动取皮刀在深Ⅱ度烧伤创面削痂时可准确控制深度,清创后创面深度均一,在清除坏死真皮层时本着“宁浅勿深”的原则,尽可能不损伤正常真皮组织及皮肤附件,改善瘀滞带血运,从而促进深Ⅱ度烧伤愈合。尽管该技术在临床已经逐步推广使用,但目前尚无科学设计、严格对照的临床试验研究,更缺乏远期的效果观察,也没有统一的操作规范和技术应用标准,其治疗是否真正优于传统换药尚需大规模随机对照临床研究证实。

表皮细胞种植技术:是一个可迅速采集自身表皮细胞并将其用于治疗自身创面的综合技术,其治疗面积可达供皮区的40-80倍,在深Ⅱ度烧伤创面削痂保留正常真皮组织的创面上实施表皮细胞种植技术有望加速创面愈合过程,该技术特点在于以微小的供皮区为代价,加速40-80倍的烧伤创面愈合。该技术在国外应用较广泛,由于价格昂贵,在国内使用尚处于起步阶段。

背景:针对目前深Ⅱ度烧伤创面治疗修复方法多样,效果不一,缺乏规范与统一,有必要开发的新技术。

目的:观察控制性清创与传统型方法对深Ⅱ度烧伤创面的治疗效果。

方法:2015年6月至2018年6月共入选80例深Ⅱ度烧伤患者,分成阳性对照组和控制性清创组进行研究,每组40例。阳性对照组外涂邦尔康烧伤抑菌霜,油纱覆盖加压包扎,分别于伤后第3,6,9,12天换药;控制性清创组按创面制备要求,制备表皮细胞悬液,喷洒至创面,用Recell套装自带保护膜覆盖创面,术后第3天打开保持干燥,随后观察术后第6,9,12天创面情况。该研究得到空军军医大学西京医院伦理委员会的批准,所有患者均自愿参加,知情并签署知情同意书。采用在线登记患者信息,并根据随机(软件在线提供)分组治疗方案进行相应治疗准备。

结果与结论:控制性清创组创面细菌含量、创面疼痛评分、创面感染评分、促炎性因子水平明显低于阳性对照组,差异有显著性意义(P < 0.05),且均未发生不良反应。该结果表明,表皮细胞种植技术结合控制性清创用于深Ⅱ度创面的治疗方案具有促进创面愈合、减轻感染、降低患者痛苦的作用,效果显著。

Abstract:

BACKGROUND: There are various methods for the treatment and repair of deep second-degree burn wounds, which have diverse effects and have no uniform standards. Therefore, new technologies need to be developed.

OBJECTIVE: To observe the therapeutic effect of controlled debridement and traditional treatment on deep second-degree burn wounds.

METHODS: A total of 80 patients with deep second-degree burns from June 2015 to June 2018 were enrolled and divided into a positive control group and a controlled debridement group, with 40 patients in each group. The positive control group was coated with Bangerkang burn bacteriostatic cream, and the oil gauze was pressure-wrapped. The dressing was changed at 3, 6, 9, and 12 days after the injury. In the controlled debridement group, epidermal cell suspension was prepared according to the requirements of wound preparation and was sprayed onto the wound surface. The wound was then covered with Recell Kit self-contained protective film. The film was removed to keep the wound dry on the 3rd day after operation, and then the wound was observed at 6, 9, and 12 days after operation. The study protocol was approved by the Ethics Committee of the Xijing Hospital of the Air Force Military Medical University. All patients volunteered to participate in the study and sign an informed consent. Patient information was registered online and appropriate treatment was performed according to a random (software online) assignment.

RESULTS AND CONCLUSION: At 3, 6, 9, and 12 days after operation, the bacterial content, wound pain score, wound infection score and pro-inflammatory factor level in the controlled debridement group were significantly lower than those in the positive control group (P < 0.05). Moreover, there was no complication in both groups. These findings reveal that epidermal cell implantation combined with controlled debridement for deep second-degree burn wounds can achieve remarkable outcomes, which can significantly accelerate wound healing, reduce infection and alleviate the suffering of patients.
