通过对122例各种脏器功能衰竭病儿的动脉血气测定,发现呼吸衰竭时的酸碱失衡类型主要为呼吸性酸中毒(63.0％),但亦可发生呼吸性碱中毒(14.8％);休克与心力衰竭病例中,代谢性酸中毒分别为82.6％和63.3％,且大多合并乳酸酸中毒;脑水肿患者中65％为单纯型呼吸性碱中毒;肾功能衰竭的病例均表现为代谢性酸中毒;严重心律失常无固定的失衡类型;外科术后2～6日内常因电解质发生紊乱而呈代谢性碱中毒。 Through the determination of arterial blood gases in 122 cases of various organ failure patients, it was found that the main types of acid - base imbalance in respiratory failure were respiratory acidosis (63.0%), but respiratory alkalosis (14.8%) could also occur. In the cases of shock and heart failure, metabolic acidosis was 82.6% and 63.3%, respectively, and most of them were complicated with lactic acidosis. 65% of patients with cerebral edema were simple respiratory alkalosis; renal failure cases showed metabolic Acidosis; severe arrhythmia no fixed type of imbalance; 2 to 6 days after surgery, often due to electrolyte imbalance and metabolic alkalosis.
