  1. aR. Analgesic: Rescue analgesic use
  2. bMin-Max values. Group T: Tramadol group; Group C: Control Group. VAS scores were expressed in median. Acetaminophen 1 g (10 mg/ml,100 ml) intravenously was given at arrival to the recovery room as a rescue analgesic, Acetaminophen with codeine analgesic 325/ 30 mg (p.o) was given at other time points as a rescue analgesic; 0: analgesic was not given; 1: one dose was given; 2: two doses were given
