EFFICACY OF DEXMEDETOMEDINE AND BUTARPHANOL ON POST SPINAL ANESTHESIA SHIVERING---A COMPARATIVE STUDY

Dr. Krishna Priya Poda, Dr. Praveen Kumar Moturi

Abstract


Purpose of the study: The most common adverse event after spinal anesthesia is shivering. Multiple etiologies have
been made responsible for this. .Opiods have been used extensively for control of shivering, but opiods are associated
with increased incidence of nausea and vomiting. So there is a need to find a drug to control shivering with fewer side
effects. In the present study we are comparing the efficacy of dexmedetomedine and butarphanol in the treatment of
post spinal anesthesia shivering along with the side effects of both the drugs
Materials and Methods: A prospective double blind randomized controlled trial was conducted in tertiary care
hospital in Visakhapatnam over a period of six months. Total 60 patients who developed shivering after spinal
anesthesiawere taken into consideration for study and were randomly allotted into two groups; Group D, where
dexmedetomedine was given and Group B where Butarphanol was given.Time for cessation of shivering with response
rate was noted. Any incidence of side effects were noted. All the results were analyzed using students T test and chisquare
test
RESULTS: In both groups D and B there was cessation of shivering. GroupDexmedetomedine had faster onset with
cessation of shivering in lesser time i.e.(170.12+12.3sec) than with butarphanol (275.06+21.725). The recurrence rate of
shivering was less with dexmedetomedine (6.66%) as compared to butarphanol (16.60%). Incidence of nausea and
vomiting was high in butarphanol , while moderate sedation of Ramsay sedation score 3-4 was noted in
dexmedetomedine group.
CONCLUSION: Dexmedetomedine is more efficacious than butarphanol in control of post spinal anesthesia shivering
with lesser side effects.
