Abstract: Background: Elderly diabetic Patients often have unstable hemodynamic states. Spinalor general anesthesia in such patients, requiring lower limb surgeries carry high risk. Surgery under effective peripheral nerve blocks is relatively safer. Aims and Objectives: To test the clinical efficacy of Sciatic Nerve Block (SNB) in elderly diabetic patients undergoing lower limb surgeries without interfering with cardiovascular stability. Methods: Anterior & Posterior approach of SNB, were performed on 100 diabetic patients of ASA I,II,III and IV, of either sex in a randomized prospective study. All blocks were performed with the use of a nerve stimulator, with 20 ml of local anesthetic mixture (10 ml 2% lignocaine, 9 ml of 0.5% bupivacaine and 1ml of sodium bicarbonate). The time of onset of sensory and motor block was assessed. Duration of analgesia following block was recorded. Data was subjected to statistical analysis. Results: Out of 100 patients 2 of anterior approach and 4 of posterior approach had a failed block and the difference had no statistical significance. Onset of block was faster with anterior group than posterior group. Duration of analgesia was significantly more with Anterior group (3.152Hrs, p=0.9864) than posterior group (2.606Hrs, p=0.9864) Conclusion: SNB for diabetic patients requiring lower limb surgeries is effective in providing excellent analgesia not interfering with cardiovascular stability. Anterior approach is more effective than posterior approach.
