Abstract:
Objective To explore the delirium incidence and risk factors among patients undergoing abdominal surgery in the post-anesthesia care unit(PACU),and establish a column chart prediction model.Methods A total of 1851 patients who underwent abdomi-nal surgery,with a surgery duration exceeding 4hours and were routinely transferred to the PACU after surgery in the First Affiliated Hos-pital of Wenzhou Medical University from January 2022 to December 2023 were selected.The patients were divided into a delirium group and a non-delirium group based on a nursing delirium screening scale score≥2.The relative factors of before and during the surgery were analyzed retrospectively.The LASSO regression was used to screen the variables,and the independent influencing factors were deter-mined using univariate and multivariate Logistic regression before creating a forest plot.The predictive efficacy of the column chart predic-tion model was evaluated by area under the curve(AUC)of receiver operating characteristic(ROC)and the Hosmer-Lemeshow test.Results A total of 113(6.1％)patients experienced delirium in the PACU.The result of the multivariate Logistic regression analysis in-dicated that gender,age,flurbiprofen,hypotension,hypothermia,hypercapnia,and surgery duration were independent influencing factors for delirium in the PACU,while a long surgery duration and using flurbiprofen were protective factors.The nomogram model was construc-ted based on the result and the AUC value of this model was 0.738.The Hosmer-Lemeshow goodness-of-fit test for the model demon-strated a good fit(P=0.686).Conclusion Medical staff should enhance intraoperative management,ensure sufficient analgesia,main-tain hemodynamic stability,reduce the incidence of intraoperative adverse events,pay attention to elderly male patients,and decrease the occurrence of delirium in the PACU.
