Analyzing Anesthetic Techniques in Diabetic Foot Amputation

Since this study was conducted retrospectively, the choice of anesthesia method was made based on our own experience. For every patient undergoing LEA under PNB, a popliteal sciatic nerve block was carried out. A saphenous nerve block was also carried out if the procedure was on a level that was close to the metatarsal bone. In some circumstances (distal surgery, such as the metatarsal bone), a sensory block on the surgical site was tried following the popliteal sciatic nerve block to demonstrate that the saphenous nerve's anatomic abnormalities required an additional saphenous nerve block. The related block was later carried out, if needed. Under ultrasound guidance, every PNB was finished.
