sodium bicarbonate

SODIUM BICARBONATE
CLASSIFICATION
Alkalinizing agent
TRADE NAME(S)
None
DESIRED EFFECTS
Treats and prevents arrhythmias in tricyclic overdoses;
rapidly drops potassium levels in serious cases of
hyperkalemia especially in dialysis and renal failure
patients; improves coronary perfusion when given with
epinephrine.
MECHANISM OF ACTION
Acts as a source of bicarbonate ions; increases pH
(alkalization) in blood and urine; acts as a buffering
(neutralizing) agent for acids in the blood and interstitial
fluid.
INDICATIONS
•
•
•
•
Metabolic acidosis
Prolonged resuscitation efforts
Tricyclic antidepressant overdose
Hyperkalemia
CONTRAINDICATIONS
•
•
•
•
Congestive heart failure
Metabolic or respiratory alkalosis
Hypokalemia
Hypocalcemia
ADVERSE REACTIONS
•
•
•
•
•
•
Hypoxia
Paradoxical CNS acidosis
Metabolic alkalosis
Hypernatremia
Seizures
May slough tissue at injection site (cytotoxic)
DRUG INTERACTIONS
•
May precipitate when given with atropine,
calcium chloride, morphine aminophylline, and
magnesium.
Epinephrine, dopamine, and isopreterenol are
inactivated when given with sodium bicarbonate
•
PRECAUTIONS
•
•
SPECIAL CONSIDERATIONS
Effective 7/1/11
Be sure to have good flow in IV prior to giving
slowly
May worsen CHF
Adequate ventilation is the mainstay of acid-base balance
in cardiac arrest. Sodium bicarbonate is reserved for
patients with severe acidosis, or empirically for prolonged
resuscitation efforts after ventilation, oxygenation, and
perfusion has been established.

DOSING REGIMEN
•
Adult –
o Full Arrest (Special Considerations) –
1 mEq/kg IV push.
o Renal Emergencies – 50 mEq IVP
o Crush Injury – 1 mEq/kg IVP the add
50 mEq to each 1000 ml of NS wide
open; additional 1 mEq/kg IVP just
before extrication
