负压吸引治疗糖尿病合并压疮的疗效观察

The clinical observation in vacuum-assisted aspiration in diabetic patients associated with pressure sores

目的探讨封闭式负压引流技术(VAC)治疗糖尿病合并压疮的临床效果。方法回顾性分析2011年1月至2013年2月间28例糖尿病合并压疮患者彻底清创术后行VAC治疗的临床资料。结果所有患者经(4.8±1.6)d引流后,创面缩小,可见新鲜肉芽组织生长。25例患者愈合,愈合率为89.3%;3例压疮明显好转,好转率为10.7%,行局部植皮治疗后愈合。全组患者平均(4.5±0.8)d天更换一次VAC装置,平均VAC治疗(14.5±5.2)d。结论封闭式负压引流技术可以缩小创面,促进肉芽组织生长,加快压疮愈合,值得临床推广应用,维持有效的负压吸引是成功的关键。

Objective To observe the clinical effect of vacuum - assisted aspiration （VAA） technique in diabetic patients associated with pressure sores. Methods The clinical data of 28 diabetic patients associated with pressure sores were included into this study. All these patients underwent VAC after thorough debridement from January 2011 to February 2013. Results The injured area of all patients after （4.8 ± 1.6） days drainage was reduced. The fresh granulation tissue grow in the surface of the wound. Twenty five patients healed. The recovery rate is about 89. 3%. The pressure sores improve markedly in 3 patients, who underwent the partial skin graft treatment. The improvement rate is about 10.7%. The VAC installment was replaced after average （4.5 ± 0.8 ） days. The average VAC treatment time is （ 14.5 ± 5.2 ） days in all patients. Con- clusion Vacuum - assisted aspiration can reduce the wound area, speed up the granulation tissue growth, accelerate pressure sores healing. It is an effective and simple to treatment in diabetic patients associated with pressure sores. However, the key of success VAA is to maintain the effective negative pressure attraction.
