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

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.

Summary
Brief summary
High dose opioid usage causes intraoperative and postoperative complications. Measuring the perioperative analgesia sufficiency and individual titration of opioids may help to decrease the complications. ANI (analgesia nociception index) technology is used for this purpose. This technology calculates parasympathetic reflex loop and shows nociceptive/antinociceptive balance. The ANI is represented as an index on a scale between 0-100 and this index reflex the parasympathetic nervous system activity and relatively intraoperative analgesia sufficiency.
Aim of this study is searching the efficacy of ANI monitorisation intraoperatively in the patients undergoing transsphenoidal pituitary surgery under general anesthesia.
