A Comparative Study of two Doses of Intrathecal Clonidine with Hyperbaric Bupivacaine in Elective Lower Abdominal and Lower Limb Surgeries
Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 10
Abstract
Introduction: For lower limb and lower abdominal surgeries, the standard anaesthetic technique is subarachnoid block. Adrenaline being the first spinal adjuvant used to increase the duration and to reduce the toxicity of spinal anaesthesia in 1903. From then on many drugs have been tried in search for an ideal adjuvant. They are opioids, sodium bicarbonate, ketamine, neostigmine, midazolam and the latest inclusion is clonidine. Aim: To study the effects of adding two doses of clonidine (30 and 45 mcg) to 12.5 mg hyperbaric bupivacaine in lower abdominal and lower limb surgeries. Sensory and motor parameters and analgesia were monitored. Materials and Methods: After getting the ethical committee approval the study was conducted in 90 patients undergoing elective lower abdominal and lower limb surgeries in Rajah Muthiah Medical College and Hospital, Chidambaram. It was a double blinded study in which patients were randomly allocated into 3 groups I, II and III. Group I received only intrathecal bupivacaine 2.5mg. Group II received bupicaine 2.5mg + clonidine 30µg. Group III received bupivacaine 2.5mg + clonidine 45µg. Sensory and motor parameters and analgesia were monitored along with the vitals of the patient. Results and Conclusion: This study shows that adding 45µg of clonidine significantly results in more duration of post operative analgesia than adding 30µg of clonidine to bupivacaine and bupivacaine alone without any side effects.
