- Type: 8.4% is common cardiac formulation
- 8.4% is 1 mEq/mL
- Dosage Forms: 5% ; 7.5% ; 8.4% ; 4.2% ; 4% ; 325mg ; 150 mEq/1000 mL-D5% ; 150 mEq/1150 mL-D5%
- Routes of Administration: IV
- Common Trade Names: N/A
- Abbreviation: NaHOC3
50 mL (1 amp) IV push for severe acidemia and patient is adequately ventilated
- 1 mEq/kg IV bolus dose initially (~1-2 amps for average adult)
- 0.5 mEq/kg/dose q10min
- OR tailor to serial ABGs
Severe Metabolic Acidemia (pH<7.1)
- IV drip
- 150 mEq/1000 mL inD5W
- May reduce 28 day mortality in patients with severe AKI and decrease need for dialysis (although this study used 4.2% sodium bicarbonate, a product not widely available within the United States)
Serum alkalinization (toxicology)
- Enhance urinary elimination of salicylates, methotrexate and phenobarbital
- Goal: serum pH of 7.5, urinary pH of 8.0
- Check K+ as well
- IV drip
- 150 mEq (3 amps) of 8.4% solution in 1000 ml D5W + potassium 20-40 mEq, max. 250 cc/hour
- 1 mL/kg IV push for severe acidemia and patient is adequately ventilated
- Sodium bicarbonate administration in cardiac arrest has not been shown to improve survival to discharge
- ACLS guidelines recommend against routine use of sodium bicarbonate in cardiac arrest although there may be benefit in the setting of cardiac arrest caused by hyperkalemia or tricyclic antidepressant overdose
- Allergy to class/drug
- Ongoing chloride loss (vomiting, gastrointestinal suction, with concurrent diuretics that induce hypochloremia)
- Extravasation- cellulitis, tissue necrosis, ulcer
- Metabolic alkalosis
- Hypernatremia 
Mechanism of Action
- Sodium acetate can be used as a substitute for sodium bicarbonate during times of critical shortages
- Can be used to treat TCA and ASA toxicity
- Cannot be given as a rapid bolus - give 1 mEq/kg over 15-20 minutes to avoid hypotension
