危重病儿都存在着不同程度的水、电解质和酸碱平衡紊乱,为此给予输液进行纠正,无疑是抢救工作中的重要组成部分。电解质紊乱及其处理一、低钾血症:临床表现不仅决定于血清钾的浓度,更重要的是缺钾发生的速度,这是因为低血钾症状的发生还和细胞内外钾的浓度差有关。起病缓慢者,细胞内外均缺钾,浓度差相对小,故临床症状不一定严重;起病急骤者,首先表现为细胞外大量缺钾,细胞内缺钾在当时尚不严重,这样细胞内外钾浓度
In critically ill children there are varying degrees of water, electrolyte and acid-base balance disorders, to give infusion correction, is undoubtedly an important part of the rescue work. Electrolyte disorder and its treatment First, hypokalemia: clinical manifestations not only depends on the concentration of serum potassium, more importantly, the rate of occurrence of potassium deficiency, which is due to the occurrence of hypokalemia and intracellular potassium concentration difference . Slow onset, intracellular and extracellular potassium, the concentration difference is relatively small, so the clinical symptoms are not necessarily severe; sudden onset, first showed a large number of extracellular potassium deficiency, intracellular potassium deficiency was not serious at that time, so that cells inside and outside Potassium concentration
