3. Fig 2
Percentage of patients receiving nalbuphine in the postoperative period, when the VAS was ≥50 (VAS scale 0–100 mm). Ketoprofen administered before induction of anaesthesia decreased the number of patients with high pain intensity and nalbuphine requirement in the postoperative 4 and 8 h compared with the preoperative propacetamol group (*P<0.05).
