Full description

Approval from Ethical Committee of Faculty of Medicine Universitas Indonesia was acquired prior conducting the study. Subjects were given informed consent before enrolling the study. Non-invasive blood pressure (NIBP) monitor, ECG and pulse-oximeter was set on the subjects in the operation room. After a tourniquet made from NIBP cuff were inflated, subjects were given either Ondansetron 8 mg or Lidocain 20 mg intravenously, then the tourniquet was set off. Hemodynamic data was recorded. Propofol 1 mg/kg of body weight (BW) injection was given. Verbal rating scale was used to measure pain at 0 s, 5 s and 30 s. Data was analyzed using Statistical Package for the Social Sciences (SPSS), for numeric data using uni-variate analysis and bi-variate analysis. Significant value is p<0.05.
