During intraoperative period, starting with remifentanil infusion after anesthesia induction and ending with termination of anesthesia in every 5 minutes
Secondary outcome [1] 342597 0
Hemodynamic stability as assessed by invasive arterial blood pressure monitoring
Timepoint [1] 342597 0
During intraoperative period, starting before anesthesia induction and ending with discharge from PACU in every 5 minutes
Secondary outcome [2] 342598 0

Timepoint [2] 342598 0
At postoperative 1th, 2nd, 6th, 12th, 24th hours
Secondary outcome [3] 342599 0
Postoperative nausea-vomiting via The Postoperative Nausea And Vomiting Intensity Scale
Timepoint [3] 342599 0
Start after PACU admission and repeated at 24th hour in the ward

Statistical methods / analysis
Descriptive analyses were presented using mean ± standard deviation (Min-Max) for the continuous variables and using frequencies and percentage for the categorical variables. The variables were investigated using Kolmogorov-Smirnov test to determine whether or not they are normally distributed. Student-t test was conducted to compare two normally distributed groups and Mann-Whitney-U test was conducted to compare two non-normally distributed groups. The distribution of categorical data among the groups was analyzed by Pearson’s Chi-square test. The sphericity assumption was assessed using Mauchly’s Test, which tests the hypothesis that the variances of the differences between conditions are equal.
Therefore, if the sphericity assumption was met, repeated-measures ANOVA was used to compare the within-group averages. If not, Multivariate ANOVA (MANOVA) was used to compare the within-group averages. Bonferroni correction was used as a multiple comparison test. Statistically significant level of p <0.05 was accepted.
