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.
