Unlike general patients, patients with diabetic foot disease often have diabetic neuropathy and thus have increased sensitivity to local anesthetics. Therefore, when performing sciatic nerve block, it is essential to properly adjust the dose to prevent neurotoxicity and delay in recovery due to local anesthetics.~If the appropriate effective dose of local anesthetic for sciatic nerve block is found in patients with diabetic foot through this study, it is expected that it will be a useful basis for establishing a safe anesthetic method in the case of diabetic foot surgery.
The purpose of this study was to determine the minimum effective dose of a local anesthetic for proper anesthesia for popliteal sciatic nerve block under ultrasound guidance in patients undergoing surgery for diabetic foot disease.
