Brief summary
Our primary aim is to evaluate the relationship between preoperative anxiety as assessed by Beck Anxiety Scale and mean platelet volume (MPV) as assessed by whole-blood assay. Our secondary aims are to evaluate the relationship between preoperative MPV and propofol induction time as assessed by observation and stopwatch and preoperative MPV and propofol consumption.as assessed by directly calculating the propofol volume infused by the perfusion device. One day before the operation the anxiety levels of the patients will be measured by Beck Anxiety Scale. The patients will be alllocated into two groups. The patients with axiety score lower than 8 points will be included in the first group (GRUP A, n=40).The patients with axiety score above 8 points will be included in the second group (GRUP NA, n=40). Then the propofol induction time and propofol consumption at the 30 minutes after induction of anesthesia will be measured for each patient.
Interventions
The preoperative anxiety levels of the patients will be assessed by Beck Anxiety Inventory at one day prior to surgery. The Beck Anxiety Inventory will be administered by an anaesthesist who is blind to study. The first 40 patients with a Beck score less than 8 will be enrolled into the first group(control group) and the first 40 patients with a Beck score equal to or greater than 8 will be enrolled into the second group.

Propofol and remifentanyl infusions and intravenous rocuronium bromide will be applied for induction and maintenance of anaesthesia. The time needed for entropy less than 60 will be recorded. Calculated total propofol consumption at the intraoperative 30th minute and time needed for eye opening will be recorded.
