Sodium Bicarbonate Injection may also be used for purposes not listed in this medication guide. these results, the suspicion of methanol poisoning was reinforced and the patient was admitted to the Intensive Care Unit (ICU) to receive the treatment, requiring mechanical ventilation, serum therapy, antidote with intravenous ethanol, sodium bicarbonate and folic acid, and hemodialysis to purify methanol molecules.  |  Decreased cardiac oxygen supply and arterial vasoconstriction may also occur secondary to metabolic alkalosis [16, 17].

Amantadine overdose may result in a similar cardiac sodium channel toxicity though IV sodium bicarbonate was not specifically used in the reported cases because of concomitant hypokalemia [48]. There were 52430 exposures to alcohols resulting in 174 fatalities in 2013 [55]. The basic steps in approach must be carried out in the emergency department and followed-up with meticulous monitoring in the intensive care unit for salvage as well as prevention of long term sequelae. This article elucidates the clinical presentation and emergency management of these cases under the framework of basic physiological and biochemical phenomena after methanol exposure. Laboratory results were significant for a severe metabolic acidosis, a serum osmolality of 465 and serum methanol level of 493 mg/dl. A. Vale, “American Academy of Clinical Toxicology practice guidelines on the treatment of methanol poisoning,”, A. Protti, A. Lecchi, F. Fortunato et al., “Metformin overdose causes platelet mitochondrial dysfunction in humans,”, J.-C. Orban, E. Fontaine, and C. Ichai, “Metformin overdose: time to move on,”, B. 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 potential benefits of exogenous intravenous sodium bicarbonate include the correction of metabolic acidosis with its associated detrimental effects. Continue dialysis until alcohol level is <20 mg/dL and acidosis resolves. Ionized calcium may be decreased, such as in metabolic alkalosis [11], which may cause tetany, decrease cardiac contractility, and potentially predispose to cardiac arrhythmias via prolongation of QT interval [12]. Since sodium bicarbonate can cause alkalosis, it is sometimes used to treat aspirin overdoses. It is important to note that mild alkalemia from a respiratory alkalosis (arterial pH < 7.55) is not a contraindication to sodium bicarbonate therapy in salicylate poisoning. A simplified view on the bicarbonate chemistry is provided in Figure 1. Methanol toxicity can have devastating visual consequences and retinal specialists should be aware of the features of this toxic optic neuropathy. The suggested regimen for IV sodium bicarbonate is similar to the above-discussed indications. [Kidney transplants from donors burdened metabolic acidosis in the course of poisoning with methanol and carbon monoxide]. Copyright © 2017 Aibek E. Mirrakhimov et al. 1. Metabolic acidosis that occurs in cases of hemodynamic deterioration potentiates the sodium blocking activity of TCA medications by increasing the binding to sodium channels [29–31]. Aibek E. Mirrakhimov, Taha Ayach, Aram Barbaryan, Goutham Talari, Romil Chadha, Adam Gray, "The Role of Sodium Bicarbonate in the Management of Some Toxic Ingestions", International Journal of Nephrology, vol. While receiving sodium bicarbonate, patients must be monitored for the development of associated side effects including electrolyte abnormalities, the progression of metabolic alkalosis, volume overload, worsening respiratory status, and/or worsening metabolic acidosis.
