Analgesia with bupivacaine under subarachnoid block in patients undergoing lower abdominal surgeries

Background and Aim: To study and compare the hemodynamic stability and duration of analgesia in spinal anaesthesia among bolus versus lower fractional doses of bupivacaine in the arachnoid block for the patients undergoing lower abdominal surgeries specifically urologic, pelvic, and lower limb surgeries. Methods: Interventional Randomized Comparative case-control study done among 70 study participants to compare analgesia with bupivacaine under subarachnoid block in patients undergoing lower abdominal surgeries. Results: To sum up, we found that the time for onset of the sensory block with a fractionated dose of bupivacaine in spinal anesthesia was significantly lesser than the time taken with a bolus dose and took a significantly longer time to regress. Conclusion: We found that patients who received a fractionated dose of bupivacaine had a faster onset of motor blockade compare
