Efficacy of Intravenousalpha2 Agonists / Opioids to Atenuate Shivering in Parturiants Undergoing Elective LSCS under Intrathecal Bupivacaine

Introduction: Post spinal shivering is very unpleasant, uncomfortable to the 55% population of parturients. Shivering increases metabolic heat production upto 600% after general or regional anesthesia.There are various methods available to control shivering during anaesthesia.We conducted study of 3 different drugs ,2 alpha agonists and 1 opioid to attenuate shivering after intrathecal bupivacaine. In present study to compare the relative efficacy of Dexmedetomidine, Clonidine and Tramadol for control of intraoperative shivering under spinal anaesthesia for Lower Segment Caesarean Section (LSCS) Study design: Randomised double blind Observation study. Aims and Objectives: The present study is undertaken to clinically compare the efficacy, haemodynamic effects, Adverse effects of Alpha2 agonists, Dexmedetomidine , Clonidine and opioid Tramadol on control of postspinal shivering in parturients. Methods: After obtaining written informed consent, We conducted a randomised Observation study in 90 parturients (30 in each group) and compared the efficacy of intravenous Dexmedetomidine Clonidine and Tramadol for controlling postspinal shivering. Patients were given inj. Dexmedetomidine(Group D) 0.5 mcg/kg,injection Clonidine (Group C I.V Clonidine 0.5mcg/kg),Tramadol (Group T - I.V Tramadol 1mg/kg)when shivering of grade 2 to 4 was noted which lasted for minimum period of 2 minutes after spinal anaesthesia. Conclusion: Intravenous Tramadol is a better alternative than I.V Alpha 2 agonists (Dexmedetomidine and Clonidine) in treatment of postspinal anesthesia shivering.
