Flashcards in Sodium Bicarbonate Deck (13):
1

Trade name

Sodium Bicarbonate 8.4%

2

Class

Buffer, Alkaline agent

3

Mechanism of action

Reacts with hydrogen ions to form water and carbon dioxide thereby acting as buffers for metabolic acidosis and increases ph. Rapid onset of action in the blood. Delayed onset of action in the tissues

4

Indications

Pre-existing metabolic acidosis; overdose of asprin, cyclic antidepressants (alkalization of blood); cardiac arrest after other interventions and ventilation is adequate, hyperkalemeia

5

Contraindications

Alkalosis; non-patent vascular access

6

Adverse effects

Congestive heart failure, edema secondary to sodium overloads; hyperosmolarity, metabolic, alkalosis, hypernatremeia, in cardiac arrest may cause extracellular alkalosis and intracellular acidosis; digitalis excess hypokalemia from sodium bicarbonate administration may worsen dysrhythmias

7

Incompatibilities/ Drug interactions

Must flush line before and after administration all drugs

8

Routes of admin

IV/IO

9

Onset of action

Onset: seconds, peak effect 1-2min, duration 10min

10

Adult dose

1mEq/kg IV

11

Pediatric dose

1mEq/kg IV

12

Special considerations

Flush tubing before and after administration, especially with concurrent use of calcium chloride
Sodium bicarbonate administration should be considered only for treatment of documented severe acidosis associated with prolonged cardiac arrest or an unstable hemodynamic state , hyperkalemia or certain overdoses (cyclic antidepressants, ASA, phenobarbital, etc)

Severe tissue necroses will occur with extravasation, asses for IV patentcy
