ABSTRACT
Objective To explore the clinical efficacy of nibble debridement combined with silver ions dressing in treatment of diabetic foot ulcer.Methods The data of 238 patients with diabetic foot ulcer in people's hospital of Meishan from January 2012 to December 2016 were retrospectively analyzed.Of which 125 patients were treated by nibble debridement combined with silver ions dressing(nibble debridement group),113 patients were treated with surgical debridement combined with silver ions dressing(surgical debridement group).The clinical efficacy,wound healing time and complication between two groups were compared.Results The wound healing time of nibble debridement group was (37.5 ± 10.8) days,which was shorter than (45.3 ± 11.7) days of surgical debridement group,the difference was significant (P ＜0.05).The total effective rate of nibble debridement group was 92.80％,which was higher than 73.45％ of surgical debridement group,the difference was significant(P ＜ 0.05).No complication occurred in two groups.Conclusion The method of nibble debridement combined with silver ions dressing treatment has a better satisfactory clinical result,shorter wound healing time and lower medical costs for patients with diabetic foot ulcer.
ABSTRACT
Objective To explore the distribution characteristics of ankle-brachial index ( ABI) examination for peripheral arterial dis-ease in diabetic patients, and to provide basis for clinical diagnosis. Methods Randomly selected 110 cases of patients who were admitted into our hospital from February 2014 to January 2015, and divided them into the observation group (34 cases with diabetic lower extremity peripheral vascular lesions) and the control group (76 cases without diabetic lower extremity peripheral vascular lesions). Measured the ABI of the two groups, and analyzed the value of ABI data range for the diagnosis of diabetic lower extremity peripheral vascular lesions. Mean-while, analyzed the risk factors of peripheral arterial disease in diabetic patients according to ABI. Results The sensitivity of ABI for diag-nosis of diabetic lower extremity peripheral vascular lesions was 91. 18%, and the coincidence rate was 95. 36%, the specificity was 98. 68%, the misdiagnosis rate was 8. 82%, and the omission diagnostic rate was 8. 82%. ABI of the observation group was obviously lower than that of the control group, and the difference was statistically significant (P<0. 05). Conclusion ABI examination could be basis of clinical diagnosis and important standard of disease assessment for peripheral arterial disease in diabetic patients. It is suggested to strengthen the control of blood glucose, blood pressure and weight of patients with diabetes in order to reduce the risk of morbidity.
