Analysis of postoperative delirium and its risk factors in elderly patients with cerebral hemorrhage in ICU
Objective To analyze the occurrence and risk factors of postoperative delirium(POD)in elderly patients with cerebral hemorrhage in intensive care unit(ICU).Methods The clinical data of 80 patients who underwent cerebral hemorrhage surgery in ICU of First Affiliated Hospital of Xinjiang Medical University from January 2020 to January 2023 were retrospectively analyzed.They were divided into POD group(n =34)and non-POD group(n =46)according to the occurrence of POD.The general data,operation time,duration of anesthesia,minimum mean intraoperative arterial pressure,postoperative hypoxemia rate,mechanical ventilation rate,postoperative catheter time and postoperative Glasgow Coma score(GCS)were compared be-tween the two groups.Logistic regression was used to analyze the risk factors for POD in elderly ICU patients with cerebral hem-orrhage.ROC curve was used to analyze the predictive value of related factors for POD occurrence in patients with cerebral hem-orrhage.Results The incidence of POD in 80 elderly ICU patients with cerebral hemorrhage was42.50%(34/80).Compared with the non-POD group,the average age of the POD group was higher.The average hospital stay,the proportion of diabetes pa-tients,operation time,cerebral hemorrhage volume,duration of anesthesia,the proportion of postoperative hypoxemia patients and mechanical ventilation patients,and postoperative catheter time were higher/longer,and the minimum mean arterial pressure and postoperative GCS score were lower,with statistical significance(P＜0.05).Logistic regression analysis showed that ad-vanced age,postoperative hypoxemia,low GCS score and excessive intracerebral hemorrhage were risk factors for POD in elderly ICU patients(P＜0.05).ROC curve analysis showed that age(AUC =0.779),postoperative hypoxemia(AUC =0.734),GCS score(AUC =0.781),and cerebral hemorrhage volume(AUC =0.711)could predict the occurrence of POD in patients with cerebral hemorrhage(P＜0.05).Conclusion Advanced age,postoperative hypoxemia,low GCS score,and excessive cerebral hemorrhage may all contribute to the development of POD in elderly ICU patients with cerebral hemorrhage.
