Background: Spinal anaesthesia remains a well-established and important technique for lower limb surgeries but with proven hemodynamic changes especially in patient with grade 3 or 4. We therefore tested the hypothesis that ultrasound guided popliteal sciatic nerve block along with saphenous nerve block is an effective alternative to central neuraxial blockade in patients undergoing below knee surgery and can be used as an sole anaesthetic technique Methods: Patients undergoing below knee surgery in Mahatma Gandhi Medical College from March 2021 to June 2022 were included in this prospective analysis. Exposures were defined as patients undergoing ultrasound guided saphenous nerve block along with saphenous nerve block with 15 ml of 0.5% Ropivacaine for each Nerve. The outcome was defined as percentage of successful block, onset time for sensory and motor block onset time and intraoperative hemodynamic changes, duration of post operative analgesia. Descriptive statistics of the study were calculated and the data was analyzed using an SPSS 23.0 software program.
