The primary outcome was incidence of postoperative infection; the secondary outcome was length of hospital stay. The associations between perioperative factors and postoperative infectious complications were analyzed using multivariable logistic regression models and the classification tree method.Results: A total of 880 patients were included in the study; of these, 111 (12.6%) had postoperative infectious complications during hospitalization, including 78 surgical site infections and 62 remote infections. After correction for confounding factors on logistic multivariable analysis, perioperative use of glucocorticoids was associated with a lower incidence of postoperative infection (hazard ratio 0.968, 95% confidence interval 0.939 to 0.997, P=0.029), and intraoperative systolic blood pressure < 90 mmHg for > 10 min was associated with a higher incidence of postoperative infection (hazard ratio 2.112, 95% confidence interval 1.174 to 3.801, P=0.013). In addition, older age, preoperative hypoproteinemia, and total gastrectomy were identified as independent predictors of postoperative infection.Conclusion: For patients with gastric cancer, perioperative use of glucocorticoids and avoiding intraoperative hypotension may decrease the incidence of postoperative infectious complications.Keywords: gastric cancer, surgery, glucocorticoids, hypotension, infection
