Description of intervention(s) / exposure
35-65 year-old, 45 ASA I and II patients, undergoing elective total abdominal hysterectomy (TAH) with or without bilateral salpingo-oopherectomy (BSO) under general anesthesia in Ankara EZH Research and Teaching Hospital, were enrolled (1:1:1) into this prospective, randomized, double-blind study. All patients received 1 mg/kg intravenous (iv) tramadol (infused in 100 ml NS over 15 minutes) and 75 mg intramuscular (im) diclofenac sodium 30 minutes before surgery. The patients were randomized into three groups (using computer-generated random numbers list with codes in sealed envelopes) to receive either placebo (Group I), 0.5 mg/kg (Group II) or 1 mg/kg (Group III) iv tramadol at the begining of the fascia closure, about 30 minutes before the end of surgery. The different doses of tramadol, prepared and labeled according to codes, were in equal volume syringes (in normal saline). Our hypothesis was ‘iv tramadol combined with im diclofenac sodium administered 30 minutes before the operation, reduces intraoperative loading dose’.
