Background and Aims: Adjuvant to the local anesthetic agent has proven benefits when used intrathecally. With regards to intrathecal bupivacaine as control, we have compared in this study the effects of clonidine and neostigmine when co-administered intrathecally with hyperbaric (0.5%) bupivacaine for abdominal hysterectomy. Materials and Methods: This prospective, randomized, double-blind study was conducted from May 2009 to June 2011. A total of 150 patients of American Society of Anaesthesiology grades I and II scheduled for abdominal hysterectomy under spinal anesthesia were randomly allocated into three groups. A volume of 3 ml of 0.5% hyperbaric bupivacaine was respectively added 1 ml solution containing 5% dextrose and 75 mcg of neostigmine in Group N, 1 ml containing 5% dextrose and 30 mcg of clonidine in Group C and 1 ml of 5% dextrose in Group D (control). We compared the sensory and motor block, the surgical condition, the duration of spinal analgesia and the side-effect profile. Results and Observations: Sensory and motor blocks and duration of spinal analgesia were significantly increased in both Group C and Group N compared to Group D. More incidences of Nausea and vomiting were observed in Group N compared to other groups. The surgical condition was poorer in Group N compared to Group C. Conclusion: Both intrathecal clonidine and neostigmine increase the bupivacaine-induced spinal block. However, clonidine provides better surgical condition and fewer incidences of nausea and vomiting.
