Spinal anesthesia (SA) with hyperbaric bupivacaine 0.5% is standard for lower segment cesarean sections (LSCS). This study compared the effects of slow versus fast injection speeds on block quality, hemodynamic stability, and recovery. Sixty patients were randomly allocated: Group A received injection over 25 sec, Group B over 50 sec. Outcomes included sensory block onset, maximum block level, hemodynamic trends, recovery parameters, analgesia requirements, and adverse events. Results showed no significant differences in block onset, maximum sensory level, hemodynamic stability, or recovery times between the groups. Rescue analgesia and adverse events were equivalent. Conclusion: Slow and fast injection speeds demonstrated equivalent efficacy and safety, supporting flexibility based on clinical context.
