ObjectiveTo investigate the completion of early ambulation in patients with gastric cancer under the enhanced recovery after surgery (ERAS) management mode in the West China Hospital of Sichuan University, and analyze the influencing factors. MethodsFrom November 1, 2021 to March 31, 2022, the patients with gastric cancer who met the inclusion criteria of this study in the West China Hospital of Sichuan University were selected as the survey objects. At 48 h after the operation, the patients were enquired at the bedside and the electronic medical records were accessed to collect the general information, diseases information, etc. of the patients. The postoperative data were also investigated, and the time of early ambulation was investigated, and the influencing factors were analyzed by logistic regression. ResultsAccording to the inclusion and exclusion criteria of this study and the sample size requirements, 140 eligible patients with gastric cancer were investigated, 34 of whom got out of bed early, and the rate of early ambulation was 24.3%. The results of binary logistic regression analysis showed that indwelling urinary catheter within 48 h after operation [OR=10.031, 95%CI（1.037, 97.061）, P=0.046] and American Society of Anaesthesiologists (ASA) grade Ⅲ [OR=4.209, 95%CI（1.792, 9.886）, P=0.001] decreased the probability of early ambulation after operation in patients with gastric cancer. ConclusionsFrom the results of this survey, the completion rate of early ambulation in patients with gastric cancer under ERAS mode is lower, which may be improved by reducing the placement of the urinary catheter or shortening the indwelling time of the urinary catheter. For patients with ASA grade Ⅲ having functional decline before surgery, doctor or nurse needs to evaluate their mobility after surgery and help them to finish early ambulation or exercise on hospital bed within their tolerances.
