Outcomes
Primary outcome [1] 302928 0
Determination effect of pregabalin on tourniquet induced ischemia reperfusion injury. For this purpose we will measure catalase, ischemic modified albumin, total antioxidant status, total oxidant status in blood samples.
Timepoint [1] 302928 0

Secondary outcome [1] 337501 0
Patient's anxiety levels will be evaluated. We will use visual analog scale for anxiety levels.
Timepoint [1] 337501 0
We have three timepoints for secondary outcome: 1 day before surgery just before given pregabalin first dose, just before second pregabalin dose, before patients go into operation room.
