15例急性肾功能衰竭患者，在透析前所有病例均有呼吸障碍。该类呼吸功能障碍可分为两类：继发于急性肾功能衰竭的单纯性肺水肿和急性肾功能衰竭合并成人呼吸窘迫综合征。透析疗法可有效地支持肾脏，并可迅速超滤体内过多的水份，纠正酸中毒，对以容量负荷为主要因素的急性肺水肿疗效明显；而急性肾功能衰竭合并成人呼吸窘迫综合征时，其发生机制复杂，透析疗法不足以改善这类患者的呼吸障碍，因此，除积极采取透析疗法支持肾脏外，还必须同时采取呼吸支持和其他脏器支持措施。
Fifteen patients with acute renal failure had a respiratory disorder in all cases before dialysis. This type of respiratory dysfunction can be divided into two categories: simple pulmonary edema secondary to acute renal failure and acute renal failure combined with adult respiratory distress syndrome. Dialysis therapy can effectively support the kidneys, and can quickly ultrafiltration of excessive body water, correct acidosis, to capacity load as the main factor of acute pulmonary edema obvious effect; and acute renal failure combined with adult respiratory distress syndrome , Its mechanism of occurrence is complicated. Dialysis therapy is not enough to improve the breathing disorders of these patients. Therefore, in addition to actively taking dialysis therapy to support the kidneys, respiratory support and other organ support measures must also be taken.
