来自主题: Nursing版 - 请教一个potassium的问题呢
为什么potassium高时, 给病人glucose 和insulin, 而不是kayexalate, 这个药不
是antipotassium吗, 总是confuse这个问题。 请高手指点一下,什么时候用glucose
和insulin, 什么时候给kayexalate。
先谢谢!

glucose 和insulin可以使K 进入细胞内,从而降低血K,kayexalate 是通过Na-K通道,我
的理解是两个办法都可,如果病人NPO或没有TUBING FEEDING的话,就不能用kayexalate,
因为它是肠道吸收

是啊。一般病人如果没有口服禁忌,都是先上kayexalate。
D50+insulin+葡萄糖醛酸钙一般是比较紧急的情况。

透析过程本身就交换了钾。钾在透析后就平衡了。
排尿是针对不做透析的情况。
尿排不出,那么肠道就是第二选择。
美国这边是给口服Kayexalate。就是你说的那种树脂。

Insulin and glucose combination works much faster and more efficient than
Kayexalate, remember BIGK, Sodium Bicarb, insulin/glucose, and Kay( we dont
use much in ICU )

Kayexalate permanent removes potassium, since potassium is removed with BM.
However, insulin plus glucose just shifts potassium from blood stream into
cells.The potassium still in the system.

来自主题: Nursing版 - 说说TELE FLOOR 吧
2。electrolyes
在CARDIAC FLOOR, 我们有standing order for potassium and magnesium
replacement. 保持 K> 4/4.5, MAG> 2。当然,如果病人有renal insufficiency , MD
会自己写医嘱。 低钾低镁有可能引发各种arrhythmias, 如果病人run NON-SUSTAIN
VT, 先看清楚是不是artifact, 量血压,问问病人当时在干什么,再数EKG STRIP有多
少BEATS,打电话给医生前,最好查查病人最近的POTASSIUM和MAGNESIUM是多少,因为
医生第一句话就会问。
还有hyperkalemia 也很常见。处理的方法 IVD50 PLUS 10U REGULAR INSULIN,
KAYEXALATE 30G PO, IV ca gluconate 1amp if EKG changes, 最后可能上DIALYSIS。
