EFFECT OF ONDANSETRON IN MITIGATION OF POST-OPERATIVE SHIVERING IN COMPARISON TO FORCED AIR WARMER AND DEXAMETHASONE IN PATIENTS UNDERGOING INFRA UMBLICAL SURGERIES UNDER SUBARACHNOID BLOCK - A PROSPECTIVE RANDOMISED STUDY

Background: Subarachnoid block in a ubiquitous technique used in the field of anaesthesia to facilitate any number of surgeries below the level of the umbilicus. However, this technique is frequently associated with post anaesthesia shivering caused by the sympathetic blockade and peripheral vasodilatation. Materials and Methods:We compared the efficacy of Ondansetron against dexamethasone and isolated forced air warming in the mitigation of sub arachnoid blockade induced shivering. We enrolled a total of 120 individuals scheduled to undergo elective infra umbilical surgeries and randomly allocated them into three groups designating each other to receive Dexamethasone (Group D), Ondansetron (Group O) and Forced air warming (Group W). we compared the three group inn respect to pre operative and post operative temperature and onset of shivering. Shivering was graded according to the Crossley Mahajan Scale. Results: We found that the statistical analysis yielded comparable results in term of demographic parameters and no statistical significance among the three group with respect to mitigation of Shivering(Chi square value = 8.5, P = 0.075).
