K+ correction

Potassium correction....
noraml value= 3.5 to 5 meq/l

Supplement K+ if it is below 3.5 meq/l
in Renal failure pt( look at s. cr...) supplement if k+ below 3.o meq/l

availble forms:
K-Dur 10mEq PO (tablet)
K-Lyte 25mEq PO (liquid): Has a lot of bicarb so if pt is alkolotic give KCl
K-Phos 2 tabs PO
K-Phos 10mmol IV (run over one hour)
Give 10mEq for every 0.1 below 4.0 so if K+ = 3 then give 100 meq
KCl 10mEq IV (run over one hour)

available forms: Potassium chloride (also citrate, acetate, bicarbonate, gluconate)
Adult
IV replacement: 10-40 mEq IV infused over 2-3 h; infusion rate not to exceed 40 mEq/h; may repeat q3-4h prn; modify infusion rate for specific requirements
PO supplementation: 50-100 mEq/d PO divided bid/tid or qd as SR formulation; larger doses may be needed in severe depletion to replenish potassium body storage

Pediatric
Usual dose for potassium replacement: 0.5-1 mEq/kg IV; not to exceed 30-40 mEq/dose
Infusion rate not to exceed 0.3-0.5 mEq/kg/h for noncritical hypokalemia; however, this rate may be inadequate in life-threatening hypokalemia
Infusion rates: >0.5 mEq/kg/h can be delivered but requires ECG monitoring to detect potentially fatal arrhythmia, especially ventricular dysrhythmia, because it can rapidly lead to cardiac arrest
PO supplementation is based on body weight, ranging from 2-4 mEq/kg/d PO in divided doses to avoid gastric distress
