目的:观察负压封闭技术对下肢大面积皮肤撕脱伤的治疗效果。方法:抽取化州市人民医院2013年6月-2014年12月收治的下肢大面积皮肤撕脱伤患者共50例,对其行原位植皮+自制负压封闭技术治疗,设为观察组。选择2007年1月-2009年1月接受原位植皮+打包换药治疗的60例患者为对照组,对两组创面愈合效果、住院时间、并发症情况进行比较。结果:观察组创面一期愈合率与对照组相比,差异具有统计学意义(P<0.05)。观察组创面愈合时间、换药次数及住院时间比较与对照组相比,差异均有统计学意义(P<0.01)。结论:负压封闭技术能明显提高下肢大面积皮肤撕脱伤患者创面一期愈合率,缩短愈合时间,并发症少。
Objective: To observe the effect of negative pressure occlusion on the skin avulsion of large area of lower limbs. Methods: A total of 50 patients with extensive skin avulsion of the lower extremities who were treated in Huazhou People’s Hospital from June 2013 to December 2014 were enrolled in this study. They were treated by in situ skin grafting and self-made negative pressure occlusion technique. Sixty patients who underwent skin graft + dressing change from January 2007 to January 2009 were selected as the control group. The wound healing, hospitalization time and complications were compared between the two groups. Results: The wound healing rate in the observation group was significantly lower than that in the control group (P <0.05). Compared with the control group, the healing time, dressing change frequency and hospital stay of the observation group were significantly different (P <0.01). Conclusion: The negative pressure occlusion technique can significantly improve the rate of primary wound healing and shorten the healing time of patients with extensive skin avulsion of the lower extremities, with fewer complications.
