摘要
目的:探讨Stanford A型急性主动脉夹层孙氏手术(全主动脉弓替换、胸降主动脉支架"象鼻"术)术后低氧血症的危险因素,为临床防治策略的制定提供理论依据。方法:回顾性分析2017年1月到2019年1月,Standord A型急性主动脉夹层76例患者的相关临床资料,将其中45例发生低氧血症的患者分为A组,未发生术后低氧血症的31例患者分为B组。对比两组患者的相关临床资料,并通过多因素Logistic回归分析Stanford A型急性主动脉夹层行全主动脉弓替换、胸降主动脉支架"象鼻"术术后低氧血症的危险因素。结果:A组患者入院时脉搏次数为(86.31±9.06)次/min,术中输注红细胞悬液量为(8.25±2.96)U,显著高于B组(P<0.05);多因素Logistic回归分析显示,术中输注红细胞悬液量是Stanford A型主动脉夹层支架置入术后发生低氧血症的危险因素(P<0.05)。结论:术中输注红细胞悬液量是Stanford A型急性主动脉夹层孙氏手术术后发生低氧血症的危险因素。临床应注意控制术中输血量,以降低术后低氧血症的发生风险。
Objective:To investigate the risk factors of hypoxemia after Stanford A-type acute aortic dissection,total aortic arch replacement,descending thoracic descending aortic stent elephant trunk surgery,and to provide a theoretical basis for the formulation of clinical prevention strategies.Methods:The clinical data of 76 patients with Standord type A acute aortic dissection from January 2017 to January 2019 were retrospectively analyzed.Among them,45 patients with hypoxemia were divided into group A.No postoperative symptoms occurred.The 31 patients with hypoxemia were divided into group B.The clinical data of the two groups of patients were compared,and the risk factors of hypoxemia after Stanford Type A acute aortic dissection with total aortic arch replacement and descending thoracic aortic stent elephant nose surgery were analyzed by multivariate logistic regression.Results:The number of pulses of patients in group A was(86.31±9.06)times/min.The amount of red blood cell infusion during operation was(8.25±2.96)U,which was significantly higher than that in group B(P<0.05).Multivariate logistic regression Analysis showed that the amount of red blood cell infusion during the operation was a risk factor for hypoxemia after implantation of Stanford Type A aortic dissection stent(P<0.05).Conclusions:The amount of red blood cell infusion during operation is a risk factor for hypoxemia after Stanford Type A acute aortic dissection with total aortic arch replacement and descending thoracic aortic stent elephant trunk surgery.Clinical attention should be paid to control the amount of blood transfusion during the operation to reduce the risk of postoperative hypoxemia.
