Abstract

Objective The purpose of this study was to assess dexmedetomidine as an adjuvant to bupivacaine as a good alternative to other adjuvants like fentanyl in epidural anesthesia. Patients and methods Ninety patients between the age of 40 and 60 years with American Statistical Association status I–III planned for elective lower abdomen surgery were enrolled in a double-blind comparative study. Patients were randomized to one of three group: group A (n = 30) patients received bupivacaine, group B (n = 30) patients received bupivacaine and fentanyl, and group D (n = 30) patients received bupivacaine and dexmedetomidine. Result Regarding demographic data, no statistically significant difference was observed among the three groups. There was a statistically highly significant difference in onset of sensory block, time to achieve peak sensory level, two-segment regression time, and duration of sensory block among the three groups. In motor block, there was a statistically highly significant difference in onset of motor block and duration of motor block. Conclusion The use of dexmedetomidine as an adjuvant to bupivacaine was a good alternative to other adjuvants like fentanyl in epidural anesthesia, and dexmedetomidine had an edge over fentanyl as an adjuvant when used with bupivacaine in epidural anesthesia.
