Any process that causes a decrease in the pH of the body as a result of the retention of acids or the loss of bicarbonate buffers. Metabolic acidosis is usually categorized by the presence or absence of an abnormal anion gap. The anion gap metabolic acidoses include diabetic, alcoholic, and...
治疗的重点是纠正原发病,应用碱性液的指征为:①HCO3-丢失过多或肾功能障碍。②酸中毒严重,应适当纠正以便进一步明确诊断。一般主张pH<7.2时才可使用。临床常用的碱性药有碳酸氢钠、乳酸钠,对慢性肾功能衰竭及肾小管酸中毒患者可选用枸橼酸钾钠口服液。
Definition Tissue acidosis is present whenever the pH is below 7.0 (or the H + -concentration is higher than 10 -7 mol/L).DefinitionTissue acidosis is present whenever the pH is below 7.0 (or the H + -concentration is higher than 10 -7 mol/L).+-7...
Acidosis in which the pH of body fluids has returned to normal. Compensatory mechanisms maintain the normal ratio of bicarbonate to carbonic acid (approx. 20∶1) in blood plasma even though the bicarbonate level is decreased or the carbon dioxide level is elevated. ...
碳酸、碳酸氢盐是体液中最重要作用最大的缓冲对,代谢性酸负荷时,H+与HCO3结合成H2CO3,H2CO3极不稳定,大部分分解成CO2和H2O,CO2通过呼吸排出体外,使血液中HCO3与H2CO3的比值保持在20:1,pH值也将保持不变,可是代偿是有限度的,如果超过了机体所能代偿的程度,酸中毒将进一步加剧。代谢性酸中毒是指体内固定酸过...

休克和严重的乳酸性酸中毒(pH值小于7.2)通常是合并症,死亡率约为50%。当pH值降至7.0以下时,尚无严重乳酸性酸中毒伴休克的存活率的报道。有趣的是,这与非休克状态相关的乳酸性酸中毒形成对照,例如在二甲双胍诱导的乳酸性酸中毒中产生的pH值为7.0,而观察到的死亡率仅...
Acidosis and alkalosis are conditions in which there is a disturbance in the pH balance (acid-base balance) of the body. Acidosis is a condition in which the bodily fluids become too acidic, with an abnormally low pH level. In alkalosis, the opposite is true: the fluids of the body are...
