摘要
报告两种实验性代谢性酸中毒以及外源性肾上腺素对血浆钾离子浓度的影响。静脉输入２Ｍ乳酸溶液造成酸中毒（ｐＨ７．００）时对血钾水平的影响不明显（从３．３４±０. ２７升至３．７１±０．４０ｍｍｏｌ／Ｌ，Ｐ＞０．０５），而输入 ２Ｍ盐酸造成同样程度的酸中毒则引起血钾水平明显升高（从 ３． ７８± ０．４９升至 ４． ５８±０．５８ｍｉｎｏｌ／Ｌ，Ｐ＜０．０５）。外源性肾上腺素在酸中毒环境下对血钾浓度影响不明显，而在对照组可引起血钾浓度的降低。
The influences of lactic/hydrochloric acidosis and epinephrine on plasma optassium level were investigated in 18 dogs. The iv infusion of lactic acid for inducing arterial pH to 7. 00 did not elicit a significant changes of plasma potassium (form 3. 43 0. 27 to 3.71 0. 40 mmol/L, P 0.05 ). However, the infusion of hydrochloric acid can increase plasma potassium concentration consistently (from 3. 78 0. 49 to 4.58 0. 58mmol/L, P). Exogenetic epinephrine led to decrease plasma optassium concentration in normal acid-base state but had little effects on plasma optassium in the metabolic acidosis.
