背景:目前对于糖尿病肢体血管病变,临床上尚缺乏可靠、迅速的评价方法。目的:探讨红外热像技术在糖尿病肢体血管病变诊断及预后评价方面的应用。设计:以诊断为依据的病例对照研究。地点、对象和方法:选择在解放军第三军医大学附属新桥医院内分泌科住院治疗过的合并轻度血管病变的糖尿病患者10例,合并重度血管病变的糖尿病患者10例,糖尿病多并发症患者20例,无并发症糖尿病患者20例进行双下肢红外线热像检查。而后对有并发症患者予以并发症治疗,作为治疗组;对无并发症患者予以降糖治疗,作为对照组,治疗结果用红外热像仪进行评价,观察治疗前后两组间的肢体温差变化。主要观察指标:两组患者治疗前后红外热像图观察的肢体变化。结果:治疗前两组患者热像检查结果比较,差异无显著性意义(P>0.05)。治疗后治疗组与对照组的肢体温差犤(0.27±0.26)℃犦较治疗前明显减小(t=6.13,P<0.001)。可见微循环明显改善。结论:红外热像技术对于糖尿病肢体血管病变的诊断及效果评价是一种可靠、迅速的方法。
BACKGROUND: At present, there is a lack of reliable and rapid clinical evaluation of diabetic limb vascular disease. Objective: To explore the application of infrared thermography in the diagnosis and prognosis of diabetic limb vascular disease. Design: A case-control study based on diagnosis. Location, Subjects and Methods: Ten patients with mild vascular disease, 10 patients with diabetes mellitus with severe vascular disease, and 20 patients with diabetic complications who were hospitalized in Department of Endocrinology, Xinqiao Hospital, Third Military Medical University of PLA Cases, 20 cases of non-diabetic patients with lower limbs infrared thermography. Then the patients with complications were treated as complication, as the treatment group. The patients without complication were given hypoglycemic treatment. As the control group, the results of the treatment were evaluated by infrared thermography. The changes of limb temperature difference between the two groups were observed before and after treatment. MAIN OUTCOME MEASURES: Changes in limbs observed by infrared thermography before and after treatment in both groups. Results: There was no significant difference between the two groups before treatment (P> 0.05). After treatment, the limb temperature difference (0.27 ± 0.26) ℃ 治 between treatment group and control group was significantly lower than that before treatment (t = 6.13, P <0.001). Micro-circulation can be seen significantly improved. Conclusion: Infrared thermography is a reliable and rapid method for the diagnosis and evaluation of diabetic limb vascular disease.
