Description
Background and Objectives: Most of the below knee surgeries are done under spinal anaesthesia. Due to more haemodynamic stability, better postoperative analgesia, early mobilization and less hospital stay, popliteal-sciatic nerve block more preferable over conventional methods. Popliteal-sciatic nerve block at branching point of tibial and common peroneal component prevents nerve sparing effects and saphenous nerve block along with it provide better analgesia over medial aspect of leg. There are various methods to perform block. In this prospective observational study, we used dual technique (USG & PNS guided technique) for popliteal-sciatic-saphenous nerve block to observe technical difficulty, ease of insertion, onset, duration and complications of block. Methods: Thirty patients were included in this study. Under all aseptic precautions, we performed popliteal-sciatic nerve block with posterior approach in prone position and saphenous nerve block in supine position by using dual technique with local anesthetic agent inj. Bupivacaine 0.5% 30ml and 10ml respectively. Data were analyzed by using STATA 14.2 version. Results: The average mean time for performing block was 33.4min while, in in-plane and out of plane techniques were 33.2min and 34min respectively. The mean onset time of sensory and motor blockade were 16.1min and 19.03min respectively. The average total mean duration of sensory blockade, motor blockade and analgesia were 8.16hours, 6.83hours and 9hours. Conclusion: We observed that dual technique for popliteal-sciatic-saphenous nerve block is very helpful for achieving analgesia and anesthesia in below knee surgeries.
