溶血是指红细胞生存期缩短,可由红细胞内、外因素所致。在短期内发生的急性溶血可引起严重贫血及组织器官缺血、缺氧,加之大量红细胞破坏形成碎片,可导致心、肝、肾等脏器的损害,严重者可危及生命。急性溶血是一种内科急症。病因血型不合引起的急性溶血溶血多发生在血型不合输血后,少数表现为母婴血型不合引起的新生儿溶血症。多属ABO血型或Rh。(O)血型不合。误输血型不合血常可引起即刻溶血反应,若发生在昏迷或麻醉中的病人则常发现较晚,致使较多异型红细胞进入患者体内引起严重溶血,常伴发急性肾功能不全,死亡率高。另外,输入ABO血型不合的 Hemolysis refers to shortened survival of red blood cells, red blood cells can be caused by internal and external factors. Acute hemolysis that occurs in a short period of time can cause severe anemia and tissue ischemia and hypoxia. In addition, a large number of erythrocytes break down and form fragments, which can cause damage to organs such as heart, liver and kidney, and can seriously threaten life. Acute hemolysis is a medical emergency. Acute hemolysis and hemolysis caused by the cause of blood incompatibility occur in the blood incompatible transfusion, a small number of manifestations of neonatal hemolytic disease caused by maternal and child blood incompatibility. Mostly ABO blood group or Rh. (O) blood group incompatibility. Misdiagnosis of blood transfusion often cause immediate hemolysis, if occurred in patients with coma or anesthesia are often found later, resulting in more heterogeneous red blood cells into the patient’s body caused by severe hemolysis, often accompanied by acute renal insufficiency, high mortality . In addition, enter the ABO blood group
