评价血液酸碱平衡状态,国际上皆用PCO_2作为判定呼吸性酸碱障碍的指标,然而如何判定代谢性障碍尚无一致意见。波士顿派主张用碳酸氢(HCO~-_3)的可信限(significance band)作为诊断标准,而哥本哈根派主张用剩余碱(Base excess)作为诊断标准。本文就所争论问题的发展加以论述。一、判定酸碱平衡障碍的历史1.储备碱(Reserve alkali) 向试管的血液内加入CO_2以外的酸(非碳
Evaluation of blood acid-base balance, the international community are using PCO_2 as a sign of respiratory acidosis, but there is no consensus on how to determine the metabolic disorders. The Boston School advocated the use of the significance band of bicarbonate (HCO ~ -_3) as a diagnostic criterion, whereas the Copenhagen school advocated the use of base excess as a diagnostic criterion. This article discusses the development of the issues under debate. First, determine the history of acid-base balance obstacles 1.
