一、高氯性代谢性酸中毒的鉴别诊断代谢性酸中毒可分为阴禽子间隙(AG)增大的正常血氯性酸中毒和AG正常的高血氯性酸中毒。典型的AG增大型见于糖尿病酮症酸中毒、尿毒症酸中毒、乳酸性酸中毒,此时酸中毒的血清氯浓度正常。而正常AG型代谢性酸中毒的血清氯浓度增高,见于肾小管性酸中毒、腹泻等消化液丢失造成的酸中毒及NH_4Cl输入过多等引起的酸中毒等。肾性HCO_3~-丢失性酸中 First, the differential diagnosis of high-chloride metabolic acidosis Metabolic acidosis can be divided into Yin-child gap (AG) increased normal blood chlorine acidosis and AG normal hyperclinical acidosis. Typical increase in AG found in diabetic ketoacidosis, uremic acidosis, lactic acidosis, acidosis at this time the serum concentration of chlorine normal. The normal AG-type metabolic acidosis increased serum concentrations of chlorine, found in renal tubular acidosis, diarrhea and other digestive juices caused by acidosis and excessive input of NH_4Cl caused acidosis. Renal HCO 3 ~ - Loss of acid
