Evaluation of Postoperative Pain in Laparoscopic Radical Prostatectomy Surgery With Tranexamic Acid: Analgesia? Hiperalgesia?

Prostate cancer is the most diagnosed cancer among men today. Radical prostatectomy is a surgery that significantly reduces disease-related mortality. The laparoscopic technique, on the other hand, is preferred because it shortens the hospital stay, faster recovery and less postoperative pain.In this study, it was planned to investigate the analgesic or hyperalgesic effects of tranexamic acid, which is widely used in the management of bleeding in trauma, orthopedic, genitourinary and gynecological surgeries. Routine noninvasive monitoring (ECG, Spo2, NIBP) will be performed when participatient are taken to the operating table without premedication. After midazolam is administered, intubation will be performed by administering 1mg/kg lidocaine, 3mg/kg propofol, 2mcg/kg fentanyl, 0.6mg/kg rocuronium. Anesthesia will be maintained with desflurane with a MAC of 1. A 0.1-0.5 mcg/kg/min remifentanil infusion will be administered by targeting 40-60 values with BIS monitoring. After intubation, 15mg/kg tranexamic acid will be given 10 minutes before the incision, and 100 mg/h infusion will be administered until the skin is closed. The control group will be given 100 ml of saline.1mg/kg tramadol and 1gr parol will be administered 30 minutes before the end of the operation. The primary objectives of the study were to learn the VAS (Visual analog scale) score at 0.6,12, 24,48,72 hours, time to first analgesic requirement, and analgesic requirement within 24 hours. Secondary purposes are to determine the amount of antiemetic used, at the beginning of the operation, Hg at the first hour and postoperative 6 hours, complications and side effects (such as DVT, pulmonary embolism).
