Abstract:
Objective:To identify the risk factors for postoperative hyperlactatemia in the patients with type A aortic dissection.
Methods:Medical records of patients with type A aortic dissection who underwent cardiovascular surgery from January 2012 to October 2017 were retrospectively collected.The patients were divided into hyperlactatemia group and non-hyperlactatemia group according to the occurrence of hyperlactatemia (blood lactic acid ≥6 mmol/L) at 8 h after surgery.The variables of which P values were less than 0.05 in univariate analysis would enter the logistic regression analysis to stratify the risk factors for postoperative hyperlactatemia in this type of patients.
Results:A total of 295 patients were included, of which 80 cases developed postoperative hyperlactatemia, and the incidence was 27.1%.Logistic regression analysis showed that preoperative acute pericardial tamponade, intraoperative deep hypothermic circulatory arrest time>35 min) and massive transfusion of blood (>1 000 ml) within 8 h after operation were independent risk factors for postoperative hyperlactatemia in the patients with type A aortic dissection.
Conclusion:Preoperative acute pericardial tamponade, intraoperative deep hypothermic circulatory arrest time>35 min and massive transfusion of blood (>1 000 ml) within 8 h after operation are independent risk factors for postoperative hyperlactatemia in the patients with type A aortic dissection.
