Abstract: Introduction: Spinal anesthesia remains a popular and effective technique for lower abdominal surgeries, providing reliable sensory and motor blockade. Among local anesthetics, bupivacaine has been widely used due to its prolonged action, though its cardiovascular and central nervous system toxicity are concerns. Ropivacaine, a relatively newer agent, offers less toxicity and a more favorable recovery profile. This study aims to compare the anesthetic efficacy of intrathecal 0.5% isobaric ropivacaine with 0.5% isobaric bupivacaine in lower abdominal surgeries. Objective: To compare the onset, duration of sensory and motor block, and the hemodynamic effects of intrathecal 0.5% isobaric ropivacaine and 0.5% isobaric bupivacaine in patients undergoing lower abdominal surgeries. Materials and Methods: A prospective, randomized, double - blind study was conducted with 90 patients undergoing elective lower abdominal surgeries. The patients were divided into two groups of 45 each: Group IR received 3 ml of 0.5% isobaric ropivacaine, and Group IB received 3 ml of 0.5% isobaric bupivacaine. Onset and duration of sensory and motor block were recorded, along with hemodynamic parameters and any adverse effects. Results: The onset of both sensory and motor block was significantly faster in Group IB compared to Group IR. However, the duration of sensory and motor block was longer in Group IB. Both groups showed stable hemodynamics with no significant differences in adverse effects, such as bradycardia and hypotension. Conclusion: Intrathecal 0.5% isobaric ropivacaine offers a shorter duration of motor blockade, making it a favorable option for shorter procedures, while 0.5% isobaric bupivacaine is more suited for surgeries requiring prolonged anesthesia due to its longer duration of action.
