Abstract:
Objective:To explore the risk factors of subsyndromal delirium (SSD) after cardiac surgery in adults and construct a risk model.Methods:The convenience sampling method was used to select 620 adult patients undergoing cardiac surgery admitted to the Surgical Intensive Care Unit (SICU) of Zhejiang Provincial People's Hospital from January 1, 2017 to December 31, 2018 as the research object. Patients with postoperative SSD were included in the SSD group, and patients without postoperative SSD were included in the non-SSD group. The preoperative, intraoperative and postoperative clinical data and various indicators of all patients were recorded in detail. Through univariate analysis and binary Logistic regression analysis, the risk factors of SSD after cardiac surgery in adults were explored, and the risk model function was constructed.Results:A total of 569 cases were included in the study. Among them, 399 cases of postoperative subdelirium did not occur (non-SSD group) , 170 cases of postoperative subdelirium occurred (SSD group) , and the incidence of SSD was 29.9%. Univariate analysis found that the influencing factors of adult SSD after cardiac surgery were age, emergency surgery, Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score, aortic occlusion time, deep hypothermia circulatory arrest time, intraoperative plasma transfusion, SICU stay time and the use of dexmedetomidine, and the differences between the two groups were statistically significant ( P<0.05) . The binary Logistic regression analysis found that age>76 years [odds ratio ( OR) =4.332, 95% confidence interval ( CI) : (2.103, 8.965) , P<0.001], emergency surgery [ OR=3.453, 95%CI: (1.143, 7.534) , P<0.05], APACHEⅡ score> 15 [ OR=5.453, 95% CI: (1.453, 9.536) , P<0.001], deep hypothermia circulatory arrest time > 34.2 min [ OR=2.132, 95% CI: (1.053, 5.532) , P<0.05] and SICU stay time > 50.0 h [ OR=1.675, 95% CI: (0.832, 5.233) , P<0.05] were independent risks of SSD after cardiac surgery in adults, and the use of dexmedetomidine [ OR=1.536, 95% CI: (0.763, 4.862) , P<0.05] was a protective factor. Conclusions:Age > 76 years, emergency surgery, APACHE Ⅱ score > 15, deep hypothermia circulatory arrest time > 34.2 min, and SICU stay time >50.0 h are independent risk factors for SSD after cardiac surgery in adults, and the use of dexmedetomidine can reduce the occurrence of SSD.
