〔Abstract〕 Objective To analyze the influencing factors of postoperative incomplete recovery in patients with type A aortic dissection. Methods A total of 88 patients with type A aortic dissection treated surgically in our depart-ment from January 2018 to November 2019 were selected as the study subjects. According to the postoperative recovery assessment,they were divided into the postoperative incomplete recovery group( n = 52) and the postoperative complete recovery group( n = 36). The body mass index( BMI),extracorporeal circulation( CPB) time,ascending aorta occlusion time,deep hypothermia cycle arrest time,intraoperative cerebral oxygen saturation,history of hypertension,and surgical treatment timing within 24 hours of onset were retrospectively analyzed. Results Univariate analysis showed that there were statistically significant differences in body mass index( P = 0. 002) and CPB time( P<0. 001),time of ascending aorta occlusion( P<0. 001),deep and low temperature shutdown cycle time( P<0. 001),history of hypertension( P = 0. 024),surgery within 24 hours of onset( P = 0. 006),and intraoperative brain oxygen saturation( P<0. 001). For the single factor analysis indicators to be statistically significant in two classifications dependent variable Logistic regression analysis,the results showed that extracorporeal circulation time( OR = 1. 150,P = 0. 001),the cycle time of cryogenic stop( OR = 1. 450,P = 0. 001),brain oxygen saturation( OR = 0. 918,P = 0. 002),hypertension( OR = 0. 682,P = 0. 015),and within 24 hours of surgery( OR = 0. 525,P = 0. 020) were statistically significant independent predictors. Conclusion Extracorporeal circulation time,deep hypothermia shutdown time,intraoperative cerebral oxygen saturation,history of hypertension,and surgery within 24 hours of onset were independent predictors of patients' recovery after type A dissection.
