Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
dexmedetomidine in a dose of 0.5Ug/Kg intravenous(i.v.) or Nefopam in a dose of 0.15mg/Kg I.v. In the respective groups.each drug was diluted into 5 ml by isotonic saline and given by slow I.v.( one minute) at the onset of shivering.either of the two drugs was given according to the group in the postoperative spinal anesthesia period to patients who develop grade III or IV shivering . When shivering recures additional dose of either of the two drugs according to the group can be given as the same previous dose and recorded.

Dexmedetomidine group is being compared to Nefopam group.
Control group
Active

Outcomes
Primary outcome [1] 293233 0
Time of stoppage of postspinal anesthesia shivering after treatment with either dexmedetomidine or Nefopam.
Timepoint [1] 293233 0
We record shivering every minute after I. V. Injection of either dexmedetomidine or Nefopam for the first five minutes of the injections and record time of its stoppage after treatment.
Secondary outcome [1] 310650 0
Duration of effective postspinal analgesia after treatment with either dexmedetomidine or Nefopam. It is calculated from intrathecal bupivacaine injection to patient first request for rescue analgesic guided by visual analogue scale . Adverse effects are not outcome of the study.
Timepoint [1] 310650 0
Duration of effective postspinal analgesia from intrathecal bupivacaine administration to first rescue analgesic request.

Safety/efficacy
Statistical methods / analysis
Numerical data will be presented as mean+/- SD and categorical data as proportions. The unpaired t- test will be used for comparison of the means of all variables between the two groups.p. value of less than 0.05 will be considered statistically significant. We hypothesized that a detectable difference between the means of time taken for cessation of post spinal shivering after treatment with either dexmedetomidine or Nefopam = 180 seconds. If we estimated a S.D. For this prospective power analysis as 20%and an alpha value of 0.05,the power of the study would be 90%.Sample size calculated to be 45.7 patients per group .To increase the power we enrolled 50 patients per group.
