  1. Sodium Bicarbonate 8.4%

    Trade Name
    Sodium Bicarb
  2. Sodium Bicarbonate 8.4%

    Class
    • Buffer
    • Alkalinizer
  3. Sodium Bicarbonate 8.4%

    Mechanism of Action
    Reacts with hydrogen ions to form water and carbon dioxide thereby acting as a buffer for metabolic acidosis
  4. Sodium Bicarbonate 8.4%

    Indications
    • Known pre-existing bicarbonate-responsive acidosis
    • Upon return of spontaneous circulation after long arrest interval
    • TCA overdose
    • Hyperkalemia
    • Phenobarbital overdose
    • Alkalinization for treatment of specific intoxications
  5. Sodium Bicarbonate 8.4%

    Contraindications
    • Metabolic and respiratory alkalosis
    • Hypocalcemia and hypokalemia
    • Hypocloremia secondary to GI loss and vomiting
  6. Sodium Bicarbonate 8.4%

    Adverse Reactions
    • Metabolic alkalosis
    • Hypokalemia
    • Hyperosmolarity
    • Fluid overload
    • Increase in tissue acidosis
    • Electrolyte imbalance
    • Tetany
    • Seizures
    • Tissue sloughing at injection site
  7. Sodium Bicarbonate 8.4%

    Drug Interactions
    • May precipitate in calcium solutions
    • Half-lives of certain drugs may increase through alkalinization of the urine
    • Vasopressors may be deactivated
  8. Sodium Bicarbonate 8.4%

    How Supplied
    50 mEq in 50 ml of solvent
  9. Sodium Bicarbonate 8.4%

    Dosage and Administration
    Adult
    • 1 mEq/kg IV; may repeat with 0.5 mEq/kg every 10 minutes
    • Infusion: 1 to 4 amps in 1 liter D5W or NS, rate determined by sending physician
  10. Sodium Bicarbonate 8.4%

    Dosage and Administration
    Pediatric
    • Same as for adult
    • Infusion: Same as for adult
  11. Sodium Bicarbonate 8.4%

    Duration of Action
    • Onset: 2-10 minutes
    • Peak effect: 15-20 minutes
    • Duration: 30-60 minutes
  12. Sodium Bicarbonate 8.4%

    Special Considerations
    • Pregnancy safety: Category C
    • Must ventilate patient after administration
    • Whenever possible, blood gas analysis should guide use of bicarbonate
    • Intracellular acidosis may be worsened by production of carbon dioxide
    • May increase edematous states
    • May worsen CHF
