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 investigate the clinical significance of WIFi classification in the risk factors of small amputation in patients with diabetic foot (DF). Methods From January 2015 to June 2016, 98 cases of DF patients admitted to our department were divided into two groups. Fifty-two small amputees were included in the observation group and the remaining 46 were non-amputated control group. Retrospective analysis of clinical data, WIFi classification, and the use of logistic regression analysis of DF patients with small amputations independent risk factors. Results There were no significant differences in gender, age, Hb A1c, body mass index (BMI), fasting blood glucose, duration of diabetes and history of hypertension between the observation group and the control group (P> 0.05) (W), ischemia (I) and foot infection (Fi) were higher than the control group (P <0.01). Multivariate logistic regression showed that W and Fi were independent risk factors of minor amputation in DF (P <0.01). Conclusions The WIFi grading issued by the American Society of Vascular Surgery for Severe Limb Ischemia (CLI) may have a role in assessing the risk of small amputations in DF patients.
