Summary: postoperative quality of recovery (qor) could be related to anesthesia and postoperative analgesia. this study is exploring early qor after radical prostatectomy in the two groups of anesthesia. the first group had a light general anesthesia with lumbal epidural anesthesia and postoperative epidural analgesia with morphine and ropivacaine. the second group had general anesthesia and a continuous postoperative analgesia with tramadol. the postoperative qor was evaluated 24 hours after surgery.

all participants were premedicated with diazepam 5 mg 12 hours and 1 hour before surgery. thromboprophylaxis ( 4,000 - 6000 iu) depending on the body weight was given at least 12 hours before surgery. all participants were warmed to prevent unintended hypothermia. participants were allocated by permuted block randomisation into one of two groups: general anesthesia group and epidural anesthesia. the randomisation list was obtained from r program version 3.5.3. the group allocations were contained in a closed envelope that were opened before surgery after the completed enrollment procedure. all patients and infusions were wormed to prevent unintended hypothermia. induction of general anesthesia was with midazolam 2.5 mg, fentanyl 100 μg, propofol 1-2 mg/kg and vecuronium 0.1 mg/kg. balanced crystalloid fluids were used to treat hypovolemia. additionally, 6% hydroxyethyl starch was used before blood transfusion products to treat profound hypovolemia. blood transfusions were given according to blood loss and clinical situation. bradycardia was treated with atropine. hypotension was treated with ephedrine boluses. anti-inflammatory drug metamizole (dipyrone) 2.5 g was given intravenously before the end of the surgery and after 12 hours after the surgery. neostigmine 2.5 mg with atropine 1 mg was used for the reversal of the effects of non-depolarizing neuromuscular blocking agents after surgery. participants were placed for one day in a urology high care unit provided with constant and vigilant nurse care. crystalloid infusions were used for maintaining diuresis. gastroprotection was done with pantoprazole 40 mg. metoclopramid 10 mg was given for postoperative nausea and vomiting (ponv). the postoperative qor was evaluated with three qor scales. scales for pain, anxiety and ponv were also examined. the 36-item short form survey (sf-36) questionnaire evaluated quality of life one month before and one month after surgery.
