【摘要】目的:研究不同负压值在轻、中度缺血性糖尿病足创面NPWT治疗中的应用效果。方法:选取重庆医科大学附属第二医院急诊外科病房住院的缺血性糖尿病足患者80例,按照踝肱指数(ABI)将其分为中度缺血组(0.5≤ABI<0.7)(n=40)和轻度缺血组(0.7≤ABI<0.9)(n=40)。在兩个缺血组内再随机分为4个处理组,每组10例创面,分别施加-20~-50 mm Hg、-50~-80 mm Hg、-80~-125 mm Hg、-125~-150 mm Hg的负压,观察患者的踝肱指数、创面温度、舒适度和创面愈合率。结果:ABI值与创面愈合率比较,A组显著高于B、C、D组(P<0.05),E组显著高于F、G、H组(P<0.05);创面温度及舒适度评分比较,A组显著高于B、C、D组(P<0.05),E组显著高于F、G、H组(P<0.05)。结论:给予轻中度缺血性糖尿病足患者-20~-50 mm Hg负压引流效果更佳。

Abstract: Objective: To study the effect of different negative pressure values in the treatment of foot NPWT with mild and moderate ischemic diabetes. Methods :80 patients with ischemic diabetic foot in the emergency surgical ward of the second affiliated hospital of Chongqing Medical University were divided into moderate ischemia group (0.5≤ABI<0.7)(n=40) and mild ischemia group (0.7≤ABI<0.9)(n=40) according to ankle brachial index (ankle brachial index). Two ischemic groups were randomly divided into four treatment groups, each group of 10 wounds, respectively applied -20~-50 mm Hg、-50~-80 mm. Hg、-80~ negative pressure of mm Hg-125-150 to observe the ankle brachial index, wound temperature, comfort and wound healing rate. Results: Compared with wound healing rate, A group was significantly higher than B、C、D group (P<0.05), E group was significantly higher than F、G、H group (P<0.05), and wound temperature and comfort score was significantly higher than B、C、D group (0.05). Conclusion: Patients with mild to moderate ischemic diabetic foot -20~-50 mm Hg negative pressure drainage effect is better.

由于糖尿病足患者创面渗液较多,特别容易感染,因此对糖尿病足患者来说,每日清洁创面以及敷料的更换非常重要。伤口负压疗法(NPWT)是治疗缺血性糖尿病足的重要手段,可加快溃疡创面的愈合,但是负压值的选择差异较大,关于最佳负压值也一直存在争议。现选取我院80例缺血性糖尿病足患者,应用NPWT,探究不同负压值在糖尿病足创面治疗中的应用,结果报告如下。
1资料与方法
1.1一般资料
选取2016年4月~2019年12月在重庆医科大学附属第二医院急诊外科80例缺血性糖尿病足患者,Wagner分级2~3级,患者生命体征平稳,均接受NPWT治疗。按照ABI将其分为中度缺血组和轻度缺血组,每组40例。两组再随机分为4个处理组,每组10例创面,具体分组见表1。中度缺血组男性21例,女性19例,年龄41~70岁,平均(59.32±4.27)岁;轻度缺血组男性20例,女性20例,年龄40~70岁,平均(59.19±4.22)岁。2组患者基本资料比较差异无统计学意义(P>0.05)。详见表1。……p>
