Sodium Bicarbonate Flashcards
Sodium Bicarbonate Trade Name
Baking soda
Sodium Bicarbonate Classification
Buffer, Alkalinizing agent
Sodium Bicarbonate Mechanism
Medscape:
Bicarbonate reacts with H+ ions to form water & carbon dioxide. It acts as a buffer against acidosis by raising blood pH
CT Protocols:
A buffer used in acidosis to increase the pH in cardiac arrest
Sodium channel blocker overdose to increase the sodium gradient across the cell membrane
Sodium Bicarbonate Onset of Action
Medscape:
15 min (IV)
Sodium Bicarbonate Duration of Action
Medscape:
1-2 hr (IV); 8-10 min (PO)
Sodium Bicarbonate Indications
CT Protocols:
* A buffer used in acidosis to increase the pH in
Cardiac Arrest.
* Sodium Channel Blocker Overdose to
increase the sodium gradient across the cell
membrane.
Capital:
Metabolic acidosis during cardiac arrest, Tricyclic antidepressant overdose,
Hyperkalemia, Crush injuries
Sodium Bicarbonate Contraindications
Capital:
Metabolic alkalosis, Hypokalemia
Sodium Bicarbonate Side Effects/ Precautions/ Comments
Capital:
Hypernatremia, Metabolic alkalosis
Deactivates sympathomimetics
Decreases effects of benzodiazepines
Repeat as needed in tricyclic antidepressant overdose until QRS narrows
Use in caution with fluid-restricted patients due to high sodium content
