水动力清创系统在上肢电弧灼伤创面的应用

目的:观察水动力清创系统(水刀)用于上肢电弧灼伤创面清创的效果.方法:2014年5月—2015年5月上海电力医院收治的53例上肢电弧灼伤患者,随机分为观察组(26例)和传统组(27例).观察组创面采用水刀技术治疗;传统组采用磨痂、削痂技术治疗.两组创面清创后均给予生物敷料(基因转染猪皮)覆盖创面.比较两组患者清创手术时间、创面愈合时间及瘢痕增生情况.结果:所有患者术后随访3~6个月.与传统组比较,观察组的手术时间、创面愈合时间均明显缩短,愈后瘢痕增生轻,差异均有统计学意义(P<0.05).结论:水刀技术可缩短上肢电弧灼伤创面的手术时间、创面愈合时间,创面愈合情况良好,瘢痕增生轻.

Observation of the therapeutic efifcacy of hydrosurgery debridement system in treatment of upper extremity arc burns

Objective:To observe the effects of hydrosurgery debridement system (hereinafter referred to as Waterjet technology) on the treatment of upper extremity arc burns.Methods: Of 53 patients with upper extremity arc burns admitted in the Shanghai Electric Power Hospital from May 2014 to May 2015, 26 cases received Waterjet debridement (observation group) and 27 cases were treated with conventional debridement techniques, including eschar grinding and shaving (conventional treatment group). After debridement, the wound surfaces in both groups were covered with biological dressing (gene transfected-pigskin). The operative time of debridement, the wound healing time and the scar hyperplasia were compared between the two groups.Results: All the patients were followed-up for 3-6 months. The operative time of debridement and the wound healing time were shorter, and the scar hyperplasia was milder in observation group than in conventional treatment group with statistical significance (P<0.05).Conclusions: Waterjet technology may shorten the operative time of debridement and the wound healing time in treatment of upper extremity arc burns with good wound healing and mild scar hyperplasia.
