Hyperkalaemia can lead to life-threatening cardiac arrhythmias. A good understanding of the physiological basis of management can help us rationalise treatment and reduce plasma potassium levels efficiently and effectively. Management focuses on avoidance of arrythmias, rapid intracellular movement of potassium and finally reduction of total body potassium. Fluid management in hyperkalaemia should be carefully considered, with balanced solutions providing theoretical benefits compared to 0.9% saline in certain situations.
高钾血症可导致危及生命的心律失常。深入了解管理的生理学基础有助于我们合理治疗并有效降低血浆钾水平。管理重点在于避免心律失常、钾的快速细胞内转移以及最终减少体内总钾量。高钾血症的液体管理应仔细考虑，平衡溶液在某些情况下相对于 0.9%生理盐水具有理论优势。
