改良负压封闭引流技术在腹部术后切口感染中的临床应用

Clinical use of modified vacuum sealing drainage in abdominal wound infections

目的:探讨改良负压封闭引流技术(VSD)在腹部切口感染中的应用效果。方法:选择2014年3月至2015月3月本科收治的胃肠外科腹部手术后发生切口感染患者40例作为研究对象,其中VSD组(20例)采用改良VSD换药,传统换药组(20例)采用外科传统换药。比较两组创面愈合、切口清洁、切口间距、换药次数。结果:改良VSD组和传统换药组1周内总有效率、治愈率分别为达100%、75%和75%、30%,两组比较,差异均有统计学意义(P<0.05)。改良VSD组和传统换药组切口清洁时间、切口最大间距、愈合时间、换药次数、换药费用比较,差异均有统计学意义(P<0.05)。结论:改良VSD可缩短切口愈合时间,提高治愈率,减轻患者经济负担。

Objective：To investigate the efficacy of modified vacuum sealing drainage （ VSD） in abdominal wound infections. Methods：Included in this study were 40 patients with wound infections developed after gastrointestinal surgery in our hospital between March 2014 and March 2015. The patients were divided into the modified VSD group （ n=20） to receive wound dressing with VSD and the conventional dressing group （ n=20） to receive wound dressing with conventional surgical dressing. The two groups were compared for outcomes of wound healing, wound cleansing, incison spacing, and number of dressings. Results： Within one week postoperatively,the overall rate of effectiveness and rate of wound healing were 100% and 75% in the modified VSD group, compared with 75%, and 30% in the conventional dressing group with statistically significant between-group differences （ P〈0.05） . There were also statistical differences in time to wound cleansing,maximum incision spacing, wound healing time, number of dressings, and medical costs of dressing between the modified VSD group and conventional dressing group （ P〈0. 05 ） . Conclusion：Modified VSD may shorten the wound healing time,improve the wound healing rate and reduce the economic burden of patients.
