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。
Valvular replacement of early postoperative hypokalemia is more common, and often have serious consequences, need to be quickly corrected. The traditional method of potassium, it is difficult to do this. Since 1990, 112 cases of patients undergoing valve replacement have received high concentrations of potassium to rapidly correct postoperative hypokalemia and have received good results. Practice has proved that 2g potassium chloride dissolved in 100ml liquid intravenous infusion, more than 1h, is very safe. High concentrations of potassium in order to quickly correct hypokalemia this method is conducive to valve replacement early low potassium patients.
