A comparative study of the efficacy of dexmedetomidine versus tramadol on post-spinal anesthesia shivering at tertiary health care center

Background: Postoperative shivering is a frequent complication of anaesthesia; it has been reported to range from 20 to 70% in general anaesthesia Aims and Objectives: A study of the efficacy of dexmedetomidine versus tramadol on postspinal anesthesia shivering at tertiary health care center. Methodology: This was a cross-sectional study carried out in the patients undergoing various surgeries under spinal anesthesia during the one year period i.e. June 2018 to June 2019 in the one year period with written and explained consent there were 50 patients were enrolled for the study. Out of these 50 patients 25 given Tramadol (Group A) and remaining 25 given dexmedetomidine (Group B) for the management of Shivering .Statistical analysis done by unpaired t-test and Chi –square test and calculated by SPSS 19 version software. Result: mean age in both the groups was comparable i.e. 38 ± 3.12 and 39± 2.97 (t=0.76,df=48,P>0.05) and the Male to Female ratio was comparable i.e. 1.5 :1 and 1:33(X2=0.35,df=1,p>0.05) .Time of onset of shivering (min) was comparable i.e. 69 .45±20.13 and 71.38±25.76 (t=1.23,df=48,p>0.05); Severity of shivering was significantly lower i.e. 4.56±0.12 and 2.93±1.02 (t=4.53,df=48,p<0.05) ; Time to disappearance of shivering (s) was significantly lesser i.e. 179.34±8.93 and 263.35±25.76 (t=5.67,df=48,p<0.01) ; Time of recurrence (min) was significantly higher i.e. 68.13±13.45 and 75.98±29.13 (t=7.84,df=48,p<0.001) respectively in Group B as Comparable Group A . Conclusion: It can be concluded from our study that dexmedetomidine was superior to tramadol with respect less severity, less time of disappearance of shivering significantly higher time for recurrence
