静脉输入高浓度氯化钾快速纠正心脏瓣膜替换术后早期低钾血症

Rapid correction of hypokalemia at early stage in valve replacement patients using high concentrated intravenous potassium chloride infusions

瓣膜替换术后早期低血钾较为多见，并常常带来严重的后果，需要快速予以纠正。而传统的补钾方法，难以做到此点。自１９９０年以来，我们对１１２例换瓣术后的病人行高浓度补钾以快速纠正术后低钾血症，收到了较好的疗效。实践证明，将２ｇ氯化钾溶于１００ｍｌ液体中静脉滴入，时间超过１ｈ，是非常安全的。高浓度补钾以快速纠正低钾血症这一方法，有益于换瓣术后早期低钾的病人。

Hypokalemia in patients at the early stage of valve replacement appears frequently,and it must be rapidly corrected.Since 1990,there are 112 patients whose hypokalemia was rapidly corrected using high concentrated intravenous potassium chloride infusions.The practice suggested the method that high concentrated potassium chloride was intravenously given to correct low potassium quickly was fine for patients with hypokalemia at the early stage of valve replecement.
