简要总结
Regional anaesthesia for lower limb surgeries has emerged as a target oriented approach as it has minimum side-effects, complications and is more cost effective. In lower limb surgeries popliteal block is a good alternative to subarachnoid block as it prevents the side-effects and complications particularly haemodynamical changes following subarachnoid block. Popliteal block can be given via prone approach or posterior approach. It can be performed using nerve stimulator technique or ultrasound technique. The present study aims to compare efficacy of popliteal block: ultrasound versus nerve stimulator technique for foot and ankle surgeries using prone approach in patients undergoing foot and ankle surgeries in Government medical college and hospital, Amritsar(Punjab). Patient will receive 30ml of 0.75% of injection ropivacaine for the block. The onset of sensory and motor block, procedure time will be assessed among the two techniques. Haemodynamics will be assessed. Intraoperative and postoperative complications will also be noted.
