Effects on Hemodynamic Parameters in Patients Undergoing Caesarean Section Under Low Dose Spinal Anaesthesia

Background: The purpose of our study was to compare the level of an adequate block with hemodynamic stability with a low dose of Hyperbaric bupivacaine and a conventional dose of bupivacaine in spinal anesthesia for patients undergoing lower uterine cesarean section in a sitting position. Methods: 60 pregnant patients belonging to ASA I and II undergoing elective cesarean section under spinal anesthesia were studied in this prospective, randomized double-blinded study. First group A (n=30) was given inj. Hyperbaric Bupivacaine 12.5 mg and group B (n=30) were given inj. Hyperbaric Bupivacaine 10 mg. Parameters like time for an adequate level of analgesia, peak sensory, and motor level reached, duration of sensory, motor block, and incidence of complications was noted in both groups. Result: The time of onset of an adequate level of sensory block (T10) and motor block was longer for group B than group A. Duration of sensory block and motor block was slightly more for group A but the duration was sufficient to conclude the surgery. Conclusion: It is concluded that subarachnoid block with inj. Hyperbaric Bupivacaine 10 mg is more hemodynamically stable and a better option for pregnant patients undergoing lower uterine cesarean section under spinal anesthesia
