选用健康家兔20只,从耳缘静脉注入12％磷酸二氢钠(5ml/kg体重),观察了注药前及注药后20、60、120min及4～5h的心电图和k~+、cl~-、Ca~(++)变化。结果:心电图以P波、Q—T间期、S—T段及T波变化为明显,S—T段的降低、T波的高尖尤为显著;血气分析,部分代偿性及失代偿性酸中毒典型模型约各占50％;血钾由实验前的15.55mg％增至21.3mg％,血钙由实验前的11.72mg％降至8.31mg％,血氯变化轻微。 Twenty rabbits with healthy rabbits were selected and 12% sodium dihydrogen phosphate (5ml / kg body weight) was injected into the ear vein. The electrocardiogram and k ~ + of 20, 60, 120min and 4 ~ cl ~ -, Ca ~ (++) changes. Results: The changes of P wave, Q-T interval, S-T band and T wave were obvious. The S-T band was decreased and the T-wave peak was more prominent. The blood gas analysis, partial compensatory and decompensated Typical models of acidosis accounted for about 50% of each; serum potassium from 15.55mg% before the experiment increased to 21.3mg%, serum calcium from the pre-test 11.72mg% to 8.31mg%, slight changes in blood chlorine.
