For below-knee procedures, adductor canal block is a promising alternative to femoral nerve block because it allows for better conservation of the functioning of the muscle strength of the quadriceps, easy visualisation, high success rate and lesser incidence of adverse effects. Hence, we aimed to estimate the time required for onset of sensory and motor block,variations in the hemodynamic parameters, associated adverse events and duration of post-operative analgesia for below – knee surgery under ultrasound guided combined popliteal sciatic and adductor canal block METHODS: This was a Descriptive study, data collection was done for the period of 18 months. Universe Sampling method done for the selection of study subjects with computerized randomisation for the allocation of interventions. Patient variables are recorded and the data were entered into Microsoft excel and analysed using SPSS 16. RESULTS: The Haemodynamic parameters such as pulse rate, diastolic blood pressure, and mean arterial pressure were stable throughout,and there was a slight increase of systolic blood pressure at 30 and 40 minutes. The Post-Op Analgesia NRS Scale score from 30 min to 150 min among the subjects were 0, The mean scores increased to nearly 0.5 from180 min to 240 min. The mean scores increased to nearly 1.5 from270 min to 300 min, to nearly 2 at 330 min and 4 at 4 hours. CONCLUSION: Ultrasound – Guided Popliteal Sciatic and Adductor Canal Block can be safe andeffective with good success rate, onset of motor and sensory blockade, haemodynamic stability, Post-Operative Analgesia, and patient satisfaction, can be recommended widely for below knee surgeries.
