Introduction: Bupivacaine and ropivacaine have identical PKA values, however ropivacaine is less fat soluble, implying that ropivacaine will block A-alpha fibers more slowly than bupivacaine. Isobaric solution has the extra benefit of not affecting the intrathecal dissemination of local anaesthetic during and after injection. The purpose of this study was to compare the anaesthetic efficacy of intrathecal isobaric ropivacaine 0.5% to isobaric bupivacaine 0.5% in lower abdominal procedures in terms of: 1. Onset and duration of sensory block, 2. Onset, quality, and duration of motor block, and 3. Hemodynamic alterations. Material and Methods: The present study was a Prospective randomized comparative Study. This Study was conducted January 2021 to December 2022 at department of Anesthesiology, Iqcty medical College nd hospital, Durgapur. Total 100 patients were included in this study. Results: Intrathecal isobaric 0.5% ropivacaine causes a delayed onset but identical length of sensory block and a statistically significant shorter duration of motor block. Both groups have identical haemodynamics and block height (highest sensory level). Conclusion: Because of the shorter length of motor blockade and comparable duration of sensory blockade, haemodynamics, and blockade height, 0.5% isobaric ropivacaine is a superior choice for ambulatory anaesthesia.
