The posterior approach to sciatic nerve block has wide clinical applicability for surgery and pain management of the lower extremity. Consequently, a sciatic block is one of the more commonly used techniques in our practice. In contrast to a common belief, this block is relatively easy to perform and associated with a high success rate. It is particularly well-suited for surgery on the knee, calf, Achilles tendon, ankle, and foot. It provides complete anesthesia of the leg below the knee with the exception of the medial strip of skin, which is innervated by the saphenous nerve. When combined with a femoral nerve or lumbar plexus block, anesthesia of the entire lower extremity can be achieved
Aims: To Study usefulness of Sciatic Block and 3 in 1 Block for lower limb surgeries contraindicated to spinal Anesthesia.
Material and Method: This procedure was evaluated in 30 patients (ASA I to IV) undergoing elective and or emergent orthopedic surgeries in our hospital.
Results: All 30 patients were given sciatic nerve block through classic posterior approach and 3 in 1 block through inguinal perivascular approach with success rate of 90%.
Conclusion: This technique could avoid centroneurexis block in haemodymic unstable patients. This is safe simple and effective alternative to spinal anesthesia for power limb surgeries especially in patients with poly trauma.
