Abstract

Background . Effective intrapartum analgesia attenuates pain, stress, and anxiety which cause release of stress hormones as well as beta-endorphins. Aim . The purpose of this study was to determine the effect of adding dexmedetomidine to hyperbaric bupivacaine for neuraxial analgesia for labor. Methods . Ninety laboring multiparous women were allocated to have single shot intrathecal bupivacaine alone (B), bupivacaine with fentanyl (BF), or bupivacaine with dexmedetomidine (BD). Sensory and motor block characteristics; time from injection to two dermatome sensory regression, sensory regression to S1 dermatome, and motor block regression to Bromage 1 were recorded. Labor pain was assessed with a 10 cm verbal pain scale. Results . Peak sensory block levels in the three groups were essentially the same (). The time for sensory and motor blocks to reach T10 dermatome and Bromage 1, respectively, was faster in group BD than in the other groups (). The time for sensory regression to S1 was significantly prolonged in the group BD (). Motor block regression time to Bromage 1 was also prolonged in the group BD (). Neonatal outcome was normal in all groups. Conclusion . Single shot intrathecal bupivacaine/dexmedetomidine significantly prolonged sensory block in laboring women.
