Abstract
Preemptive analgesic efficacy of caudal ropivacaine vs bupivacaine- A randomized study in patients undergoing single level lumbar discectomy
Objective: The objective of the present study was to compare the preemptive analgesic efficacy of single preincisional caudal epidural injection of 0.2% bupivacaine with 0.2% ropivacaine in patients undergoing single level lumbar discectomy.
Materials and Methods: 100 patients of ASA physical status I undergoing single level lumbar discectomy under general anesthesia.Patients were randomized into two groups of 50 each. After tracheal intubation, patients were placed in prone position. Caudal block was given with 50 microgm of fentanyl and 20ml of either 0.2% ropivacaine (group R) or 0.2% bupivacaine (group B).
Results: The mean intraoperative and postoperative heart rates were significantly lower in bupivacaine group compared to ropivacaine group. Incidence of sinus bradycardia (HR
