Cocaine Toxicity

1-2 mEq/kg IV push bolus

Cyanide Toxicity

1-2 mEq/kg IV push bolus

Salicylate Toxicity

100-150 mEq IV with 40-80 mEq of potassium chloride in each liter of D5W; administer at 150-250 mL/hr to maintain higher than normal urine output

Barbiturate Toxicity

Maintenance: 0.5 mEq/kg/dose q10min or as indicated by arterial blood gases

Tricyclic Antidepressant Toxicity

Use if QRS >100-200 ms or hypotension

Initial bolus: 1-2 mEq/kg IV push over 1-2 minutes; not to exceed 100 mEq/dose

Pregnancy & Lactation

Pregnancy Category: C

Pregnancy Categories

A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

NA:Information not available.

Pharmacology

Mechanism of Action

Increases blood and urinary pH by releasing a bicarbonate ion, which in turn neutralizes hydrogen ion concentrations

1g of sodium bicarbonate is equivalent to 11.9 mEq each of sodium and bicarbonate

Pharmacokinetics

8-10 min (PO); 1-2 hr (IV)

Excretion: Urine (<1%)

Onset of action: Rapid (PO); 15 min (IV)
