Abstract:
【Objective】 To investigate the factors affecting the length of hospitalization after the Sun's procedure in patients with type A aortic coarctation. 【Methods】 From January 2018 to June 2023, the clinical data, related laboratory indicators and perioperative blood transfusion data of patients with type A aortic dissection who underwent Sun's procedure in the First Hospital of Lanzhou University were collected. LASSO regression was used to screen the characteristics related to the length of hospital stay, and linear regression analysis was used to determine the risk factors for prolonged length of hospital stay. 【Results】 The statistical analysis of 242 patients showed that the amount of red blood cell transfusion, plasma transfusion, platelet transfusion and autologous blood transfusion were the influencing factors of the length of hospital stay in patients with type A aortic dissection after operation. The total sum of squared deviations of the linear regression equation fitting the total length of hospital stay was statistically significant (F= 10.504, P<0.001). 【Conclusion】 Perioperative red blood cell transfusion,plasma transfusion,platelet transfusion and autologous blood transfusion are risk factors for prolonged postoperative hospitalization in patients undergoing the Sun's procedure for type A aortic coarctation. Control of operation time and reduction of intraoperative blood loss may help to prevent prolonged postoperative hospital stay and other adverse conditions.
