Abstract:
Objective:To explore the current status of postoperative delirium in elderly patients with heart valve replacement and to analyze the relationship between preoperative weakness and postoperative delirium.Methods:The convenient sampling method was used to select 156 elderly patients who received heart valve replacement surgery in Department of Cardiovascular Surgery of Guangdong Provincial People's Hospital Zhuhai Hospital (Zhuhai Golden Bay Central Hospital) from August 2018 to August 2021 as the research objects. The general information questionnaire and Frailty Scale were used to investigate the patients before operation, and Confusion Assessment Methods was used to evaluate the patients on the 3rd day after operation. Binomial logistic regression analysis was used to investigate the risk factors of postoperative delirium in elderly patients with heart valve replacement. A total of 156 questionnaires were distributed, 11 invalid questionnaires were excluded and 145 valid questionnaires were finally collected, with an effective recovery rate of 92.95% (145/156) .Results:Among 145 elderly patients with heart valve replacement, 42 cases (28.97%) developed delirium after operation and 103 cases (71.03%) did not develop delirium after operation. 76 cases (52.41%) were frailty before operation, 69 cases (47.59%) were non-frailty before operation. Among which 31 cases (40.79%, 31/76) of preoperative frailty patients developed postoperative delirium and 11 cases (15.94%, 11/69) of preoperative non-frailty patients developed postoperative delirium. Binomial Logistic regression analysis showed that age, preoperative frailty and preoperative cardiac dysfunction were the influencing factors of postoperative delirium in elderly patients undergoing heart valve replacement ( P<0.05) . Conclusions:The incidence of postoperative delirium is high in elderly patients with heart valve replacement. Patients older than 75 years, in a frailty state before surgery and in combination with cardiac insufficiency are prone to postoperative delirium.
