重症肝炎可以分为急性(暴发性)、亚急性两型。急性重症肝炎又称为暴发性肝衰竭,常为急起黄疸,早期出现精神、神经症状;国外以药物中毒引起者多见,国内主要为乙型肝炎病毒所致,也可见于甲型及非甲、非乙型肝炎。亚急性重症肝炎又称亚急性肝衰竭,常有深度黄疽、出血、腹水,神经、精神症状出现较迟。Gimson报告英国以非甲、非乙型肝炎病毒引起者较为多见,我国仍以乙型肝炎病毒为主。Ro-ger Williams认为亚急性肝衰竭的预后较急性者预后为差,存活率各为7.1％及31.1％。由于临床过程及预后均有所不同,发病机理可能也有所区别,但由于重症肝炎引起肝细胞广泛坏死的机理十分复杂,各
Severe hepatitis can be divided into acute (fulminant), subacute two types. Acute severe hepatitis, also known as fulminant hepatic failure, often acute jaundice, early mental, neurological symptoms; caused by drug poisoning abroad more common, mainly due to hepatitis B virus, but also found in A and non A, non-Hepatitis B Subacute severe hepatitis, also known as subacute hepatic failure, often depth of jaundice, bleeding, ascites, nerves, mental symptoms appear later. Gimson reported that the United Kingdom non-A, non-hepatitis B virus caused more common in our country is still based on hepatitis B virus. Roger Ger Williams believes that the prognosis of subacute liver failure is worse than the prognosis of acute and the survival rates are 7.1% and 31.1% respectively. As the clinical course and prognosis are different, the pathogenesis may also be different, but due to severe hepatitis caused by a wide range of mechanisms of liver cell necrosis is very complicated, each
