Routine administration of sodium bicarbonate is not recommended in cardiac arrest. (Class III, LOE B)

Sodium bicarbonate may be administered for treatment of some toxidromes (see “Toxicological Emergencies,” below) or special resuscitation situations such as hyperkalemic cardiac arrest.

Precautions

During cardiac arrest or severe shock, arterial blood gas analysis may not accurately reflect tissue and venous acidosis.1,2 Excessive sodium bicarbonate may impair tissue oxygen delivery;3cause hypokalemia, hypocalcemia, hypernatremia, and hyperosmolality;4,5 decrease the VF threshold;6and impair cardiac function.
