Univariate and multivariate logistic regression analyses were used to identify the risk factors of postoperative pain.Results In total, 2180 patients were included in the final analysis. 183 patients (8.4%) suffered moderate-to-severe pain within 24 hours after operation. The independent risk factors associated with moderate-to-severe pain 24 hours after procedures were younger age (OR, 0.97; 95% CI 0.95 to 0.98, p<0.001), lower body mass index (BMI) (OR, 0.94; 95% CI 0.89 to 0.98, p=0.018), open surgery (OR, 0.34; 95% CI 0.22 to 0.52, p<0.001), and postoperative analgesia protocol with sufentanil (OR, 4.38; 95% CI 3.2 to 5.99, p<0.001). Postoperative hospital stay was longer in patients with inadequate analgesia (p<0.05).Conclusion Age, BMI, laparoscopic surgery, and different analgesic drugs were significant predictors of postoperative pain after major hepatobiliary and pancreatic surgery.Trial registration ChiCTR2100049726.Data are available upon reasonable request.
