What do we do with such a Value?
Repolarize!
Calcium gluconate
10 to 20 mL of 10 percent solution IV over two to three minutes
Immediate
30 minutes
Protects myocardium from toxic effects of calcium; no effect on serum potassium level
Can worsen digoxin toxicity
Insulin
Regular insulin 10 units IV with 50 mL of 50 percent glucose
15 to 30 minutes
Two to six hours
Shifts potassium out of the vascular space and into the cells; no effect on total body potassium
Consider 5 percent dextrose solution infusion at 100 mL per hour to prevent hypoglycemia with repeated doses. Glucose unnecessary if blood sugar elevated above 250 mg per dL (13.9 mmol per L)
