Interventions
Arm 1: single dose intraoperative intravenous parecoxib 40 mg Arm 2: single dose intraoperative intravenous paracetamol 2 g Arm 3: single dose intraoperative intravenous parecoxib 40 mg and intravenous paracetamol 2 g Arm 4: single dose intraoperative intravenous placebos This 2 x2 factorial design allows efficient evaluation of two treatments and in this case comparison not only of parecoxib versus placebo and paracetomol versus placebo but also the interaction of these two drugs (both versus placebo) and evaluation of all patients receiving each drug eg. Arms 1 & 2 vs Arm 4 and Arms 2 & 3 vs Arm 4.
