采用WIFi分级分析糖尿病足小截肢相关危险因素

Analysis of risk factors of minor amputation among patients with diabetic foot by WIFi classification system

目的探讨WIFi分级分析糖尿病足(DF)患者发生小截肢危险因素的临床意义。方法2015年1月至2016年6月我科收治的98例DF患者分为两组,52例小截肢者列入观察组,其余46例为非截肢对照组。回顾性分析患者临床资料、WIFi分级情况,并采用logistic回归分析DF患者发生小截肢的独立危险因素。结果观察组与对照组在性别、年龄、糖化血红蛋白(Hb A1 c)、身体质量指数(BMI)、空腹血糖、糖尿病病程、高血压病史统计学无差异(P﹥0.05),观察组足部创面(W)、缺血(I)、足部感染(Fi)的平均分级较对照组高,差异具有统计学意义(P﹤0.01)。多元logistic回归显示W、Fi是DF发生小截肢风险的独立危险因素(P﹤0.01)。结论美国血管外科协会发布的针对严重下肢缺血(CLI)的WIFi分级对DF患者小截肢风险具有一定的评估作用。

Objective To evaluate the risk factors of minor amputation among patients with diabetic foot(DF) by WIFi classification system.Methods A total of 98 patients with DF admitted between January2015 and June 2016 were divided into two groups.Fifty-two patients underwent minor amputation were set into observation group,while 46 patients without amputation as the controlled group.Clinical data,WIFi classification of these patients were analyzed retrospectively.The high risk factors of DF minor amputation were analyzed by logistic regression method.Results Clinical data such as gender,age,hemoylobin Alc(Hb A1 c),body mass index(BMI),blood glucose,the history of diabetes and hypertension were not significantly different between two groups(P﹥0.05).There was significant difference between two groups in the WIFi classification system(P﹤0.01).Multivariate logistic regression analysis showed that serious foot wound and infection in the WIFi classification system were independent risk factors of DF minor amputation(P﹤0.01).Conclusion It is feasible using WIFi classification system issued by Society for Vascular Surgery of USA to evaluate the risk of minor amputation among patients with DF.
