Introduction: Diabetic foot syndrome (DFS) is the major cause of hospitalization for diabetes-related complications. Protective sensation loss and impaired vision increase the susceptibility for minor feet trauma, which results in diabetic foot ulceration with or without subsequent infection. Peripheral arterial disease is a major cause of impaired ulcer, wound healing and gangrenous diabetic foot. The most important intervention to prevent diabetic foot ulceration and its consequences is early recognition of high-risk patients and their risk factors and referral to appropriate medical departments. There are various risk factors for major lower extremity amputations related to diabetic foot, which includes microvascular diseases, infections, long duration of diabetes, poor glycemic control, peripheral arterial disease, old age and associated cardiovascular comorbidities.
Material and Methods: This study was done on the review of medical records of consecutive type 2 diabetic patients. Admitted patients were treated and managed according to the standard protocol of the hospital. History, clinical and physical examination were carried out on each patient. Ulcer characteristics like infection and depth of the ulcer, site of ulcer were assessed. Associated diabetic neuropathy and peripheral arterial disease was assessed by a clinical method. Age, sex, body mass index (BMI), smoking, duration of diabetes, diabetic control therapy, associated hypertension, cardiac diseases were recorded. The glycated haemoglobin level (HbA1c) were recorded.
Results: A total of 128 patients with diabetic foot were included in the study of which 76(59.4%) were male and 52(40.6%) were female. Of the 76 male 6 (4.7%) had major amputation and out of 52 female 4(3.1%) had major amputation, thus total number of major amputations were 10(7.8%). Statistically significant difference was observed in HbA1C and duration of diabetes group in amputation. High HbA1C and more duration of diabetes was associated with the higher number of amputation. The rate of amputation was much higher among patients hypertension, smoking, cardiac diseases and stroke. Conclusion: Poor glycemic controls and duration of diabetes are the important independent risk factors for diabetes-related major lower extremity amputations.
