Potassium

  • Usual dose is 40meq IV or PO unless the level is <2.5, then both should be used.
  • 10meq will raise the serum level by 0.1
  • Intravenous K+ typically runs at 10meq/hour, burns when infused, and may cause phelbitis/sclerosis if run faster
  • Oral Potassium more quickly absorbed and preferred
  • KCl elixir easily swallowed, but tastes terrible, KDur oral tablet is large and hard to swallow.
  • Serum K+ will not respond if patient has concurrent hypomagnesmia

Magnesium

  • Replete if serum level if less than 1.7
  • Usual dose is 2g over 1 hour
  • If level is less than 1.2, double the dose
  • Oral repletion may done if level is above 1.2 and the patient is asymptomatic
  • Magnesium Oxide 400mg is approximately equal to 2g of MgSO4

Phosphorus

  • Replete if level is less than 2.4
  • Oral: Neutra-Phos 2 packets PO Q6 hours x 48 hours
  • IV: 30mmol Sodium Phosphate.
  • If level is less than 1.0, 45mmol IV Sodium Phosphate should be used.
