脑出血后除了因血肿使颅内压骤然升高外,随之而起的脑水肿亦是颅内压增高的重要原因。已有许多尸检资料证实,死于脑出血急性期的患者,均有明显之脑水肿。脑实质内的大块出血和脑水肿常引起脑移位、脑疝和脑干受压,从而造成呼吸和循环中枢麻痹,以致死亡。根据本科的经验,急性期脑出血病人有脑干损伤症状者占38.4%;44例尸检中见有天幕疝和枕大孔疝者占70— In addition to cerebral hemorrhage after intracranial pressure due to hematoma suddenly increased, the accompanying brain edema is also an important reason for increased intracranial pressure. There have been many autopsy data confirmed that patients died of acute cerebral hemorrhage, have obvious cerebral edema. Large intracranial hemorrhage and hydrocephalus within the parenchyma often cause brain displacement, hernia and brainstem compression, resulting in respiratory and circulatory center paralysis, resulting in death. According to the experience of undergraduate, patients with acute cerebral hemorrhage have symptoms of brain stem injury accounted for 38.4%; 44 autopsy see the cantilevered hernia and hernia accounted for 70-
