本文分析87例肺性脑病与多器官功能衰竭的关系。结果表明，肺性脑病100％并发多器官功能衰竭。最常见的受损器官是肺、心、脑、肝或肾。随衰竭器官数目的增多，病死率亦增加，5个以上器官衰竭者的病死率为100％。肺性脑病时呼酸代酸、低钠血症、低氯血症明显增多，提示酸碱失衡及电解质紊乱与多器官功能衰竭有关。 This article analyzes the relationship between 87 cases of pulmonary encephalopathy and multiple organ failure. The results show that 100% of pulmonary encephalopathy complicated by multiple organ failure. The most common damaged organ is lung, heart, brain, liver or kidney. As the number of failing organs increases, the case fatality rate also increases, with more than 5 organ failure cases with a 100% mortality rate. Lung acidosis, acidosis, hyponatremia, hypochlorosis increased significantly, suggesting that acid-base imbalance and electrolyte imbalance and multiple organ failure.
