However, ten minutes later the QRS abnormalities recur. may be accompanied by hyperirritability or tetany. Patients with salicylate poisoning are often alkalemic on presentation with hyperventilation. In vitro studies in human cardiac myocytes suggest that the bicarbonate component promotes dissociation of the tricyclic antidepressant imipramine from sodium channels at higher serum pH. Should alkalosis result, the bicarbonate should be stopped and the patient managed according to the degree of alkalosis present. ​Sodium bicarbonate administration is a suggested treatment modality for a variety of toxicologic and nontoxicologic conditions such as poisonings by tricyclic antidepressants, toxic alcohols, and salicylates, and other conditions such as hyperkalemia. The benefit of sodium bicarbonate in the setting of TCA overdose is probably due to both an increase in serum pH and the increase in extracellular sodium. The evidence for sodium bicarbonate in TCA overdose consists largely of case reports and animal studies. You may report side effects to FDA at 1-800-FDA-1088. The high sodium load increases the electrochemical gradient across cardiac cell membranes, potentially attenuating the TCA-induced … While some have advocated the use of continuous sodium bicarbonate infusions, this has not been well studied.

Sodium bicarbonate (NaHCO3) is used primarily to combat acidosis, although it’s the treatment of choice in certain cases of overdose. Although physostigmine is considered an acceptable antidote for severe DPH toxicity, adverse effects such as seizures and cholinergic crisis may occur. Hyperosmolar sodium bicarbonate solutions are widely used in clinical toxicology both as an antidote to drugs that impair fast sodium channel function and as an alkalinising agent to manipulate drug distribution and excretion (salicylate and phenobarbitone). Generally, the target for serum pH is 7.4 – 7.5. Over the course of the next several hours, the patient receives ten ampules of sodium bicarbonate. The clinical scenarios in which sodium bicarbonate may be utilized vary widely. In addition to use in treatment of poisonings with sodium channel blocking activity, sodium bicarbonate may also be used as adjunctive therapy in poisonings due to methanol, ethylene glycol, and salicylates. Sodium bicarbonate is also used to treat certain drug intoxications, including barbiturates, or salicylates or methyl alcohol poisoning. Typical EKG findings include prolonged QRS duration, prolonged QT duration, or ventricular dysrhythmias. It is used to treat aspirin overdoses since sodium bicarbonate can cause alkalosis, and the acidic environment helps in the absorption of aspirin. Should alkalosis result, While the possible association with Rye’s syndrome significantly reduced the utilization of aspirin in this country years ago, its presence has been rejuvenated as the drug’s cardio-protective activity has been realized. Drugs and toxins that act as sodium channel antagonists include agents listed in List 1. Salicylate poisoning often presents with a mixed metabolic acidosis and respiratory alkalosis, due to the mixed effects of aspirin on the pulmonary system and cellular respiration. Laboratory test for serum concentrations to gauge the degree of toxicity will not be available for most of these agents. or phlebitis extending from the site of injection, extravasation, and hypervolemia. Severe alkalosis may be controlled by parenteral injections Severe alkalosis may be controlled by Urinary alkalinization will ionize the drug in the urine preventing resorption by the kidneys back into the blood, thus enhancing toxin elimination. Because many agents with sodium channel blocking properties also have antimuscarinic effects, poisoned patients may also experience signs and symptoms in Table 2. Should alkalosis result, the bicarbonate should be stopped and the patient managed according to the degree of alkalosis present.
