Acute type A aortic dissection is a life-threatening disease associated with high morbidity and mortality that requires urgent surgical intervention. Hemodilution is inevitable in cardiac operations performed with cardiopulmonary bypass, which leads to nadir hematocrit levels. Studies have shown that nadir hematocrit levels are associated with poor postoperative outcomes. The management strategy of intraoperative anemia in these operations is still controversial. Should we follow the patients with intraoperative low hematocrit values or should we transfuse them? In addition to intraoperative nadir hematocrit, cannulation strategies play an important role in early postoperative outcomes after aortic dissection surgery.
急性 A 型主动脉夹层是一种危及生命的疾病，发病率和死亡率都很高，需要紧急手术干预。体外循环下心内直视手术不可避免地会发生血液稀释，导致最低红细胞压积水平。研究表明，最低红细胞压积水平与术后不良结局有关。这些手术中术中贫血的管理策略仍存在争议。我们应该遵循术中低红细胞压积值的患者，还是应该给他们输血？除了术中最低红细胞压积外，插管策略在主动脉夹层手术后的早期术后结果中也起着重要作用。
