Fourth, the data on the role of sodium bicarbonate in the management of salicylate poisoning will be provided. Continue dialysis until alcohol level is <20 mg/dL and acidosis resolves. It is important to remember that the pharmacopathogenesis of TCA toxicities is more complex than just sodium channel blockade and also includes inhibition of muscarinic, alpha-1 adrenergic, and antihistamine receptors [23]. A. Nierenberg, “A critical review of pharmacotherapy for major depressive disorder,”, W. A. Watson, T. L. Litovitz, G. C. Rodgers Jr. et al., “2004 Annual report of the American Association of Poison Control Centers Toxic Exposure Surveillance System,”, P. K. Gillman, “Tricyclic antidepressant pharmacology and therapeutic drug interactions updated,”, K. H. Choi and K.-U. It is commonly known to cause blindness but it also can be lethal, particularly if the patient has deliberately ingested methanol with a suicidal intent. IV administration of sodium bicarbonate represents only one aspect of the complex management of medication and chemical toxicities, and, for a thorough discussion of the management of these toxicities, the reader is referred to focused reviews. In rare circumstances (such as acute illness and worsening renal function), metformin administration may result in the development of lactic acidosis that is believed to be secondary to mitochondrial dysfunction, with a shift towards anaerobic glycolysis [60–62]. Carbon dioxide (CO2) is a major byproduct of energy metabolism in living organisms and a conjugate acid. Sodium bicarbonate has also been used in the treatment of tricyclic antidepressant overdose. Lukasik-Głębocka M, Sommerfeld K, Kapala M, Adamek R, Panieński P, Zielińska-Psuja B, Samborski W. Peces R, Fernández R, Peces C, González E, Olivas E, Renjel F, Jiménez M, Costero O, Montero A, Selgas R. Kołaciński Z, Skrzypek-Mikulska A, Pitrus E, Matych J, Winnicka R, Czyzewska S, Krakowiak A. Clin Toxicol (Phila). Diagnosis of methanol poisoning is based on the sus-picion of ingestion, the presence of visual disturbances, the onset of metabolic acidosis with elevated anion and osmolar gaps, and markedly increased liver enzymes. 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. Pharmacological agents targeting sodium channels are used in cardiac electrophysiology and neurology (particularly in the areas of pain management and epilepsy) [19, 20], as well as depression [21]. Methanol is not found in Australian methylated spirits. Field, H. Nohara, and K. Yamashita, “Counterproductive effects of sodium bicarbonate in diabetic ketoacidosis,”, W. A. Neill and M. Hattenhauer, “Impairment of myocardial O2 supply due to hyperventilation,”, J. R. Wilson, S. Goldberg, J. W. Hirshfeld, and A. H. Harken, “Effects of respiratory alkalosis on coronary vascular dynamics and myocardial energetics in patients with coronary artery disease,”, C. H. Peters and P. C. Ruben, “Introduction to sodium channels.,”, M. R. Rosen and P. J. Schwartz, “The Sicilian gambit. Bicarbonate is an essential chemical regulating the acid-base balance acting as a buffer [2]. Constituents and characteristics of commonly used crystalloids and plasma. As in the management of other discussed toxidromes, the literature on the benefits of IV sodium bicarbonate originates from case reports and consensus guidelines [58, 59]. Due to greater permeability of the blood-brain barrier to hydrogen than to bicarbonate, the pH of cerebrospinal fluid may significantly decrease during sodium bicarbonate administration, which can cause mental stupor or coma. Methanol poisoning is generally treated with the usage of a buffer solution, such as sodium bicarbonate, to correct the metabolic acidosis and an antidote to inhibit metabolism of methanol to its toxic metabolite, formic acid. Severe metabolic acidosis: 90 to 180 mEq sodium bicarbonate diluted in 1 L of D5W to be intravenously infused at a rate of 1 to 1.5 L/hour during the first hour. The urinary clearance of methotrexate, phenobarbital, chlorpropamide, and fluoride is increased after reaching urinary pH levels of 7.5–8.0 via formation of lipid insoluble metabolite of the parent drug. When administered, sodium bicarbonate dissociates into a molecule of sodium and bicarbonate. 2010 Jun;48(5):401-6. doi: 10.3109/15563650.2010.495347. NIH Acute kidney injury warrants urgent haemodialysis. Methanol poisoning may cause coagulopathy, so be careful if anticoagulation is being used to facilitate dialysis. The data on the management of metformin-associated lactic acidosis, chlorpropamide, methotrexate, and phenobarbital is even more limited. Nevertheless, these adverse effects of sodium bicarbonate such as an increase in systemic pH and high sodium load may be useful in the management of certain pharmacological toxicities and overdoses. Sodium bicarbonate (NaHCO3) is one of the few pharmacological agents aiming to mimic the endogenous effects of . Drugs and toxins that act as sodium channel antagonists include agents listed in List 1. Early after an ingestion of too much baking soda, vomiting and diarrhea are common as the body tries to correct the high sodium concentration by pulling more water into the digestive tract. Though the literature on the role of systemic bicarbonate administration in cases of metformin poisoning is very scant, the use of IV sodium bicarbonate should be probably limited to nonanuric patients with metformin-associated advanced metabolic acidosis and pH < 7.1, given the questionable efficacy and potential for adverse effects. Acidemia leads to protonation of methanol and ethylene glycol metabolites to uncharged molecules (e.g., formic acid and oxalic acid), making them more likely to penetrate end-organ tissues (such as the retina) and more likely to be reabsorbed across the renal epithelium from the urine [58]. The concurrence of cases from a particular area raises doubts about methanol as the culprit. The patient will often be given intravenous fluids and electrolytes, airway management, and be evaluated and treated for any existing neurological or cardiovascular problems resulting from the methanol poisoning. Finally, we will discuss the place of sodium bicarbonate in the management of toxic alcohol ingestions. 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. Am J Kidney Dis. Sodium bicarbonate is commonly administered as 8.4% solution 1-2 mEq/kg (see Table 1) in cases of TCA associated ECG abnormalities (such as QRS prolongation > 100 msec), hemodynamic compromise, and malignant ventricular arrhythmias [34–36]. The authors declare that they have no conflicts of interest regarding the publication of this paper. It is chemically known as sodium bicarbonate and has a variety of other applications; Baking soda is used for baking breads and cakes. etoxicmethanoldoseis mL(mg/kg), Decreased cardiac oxygen supply and arterial vasoconstriction may also occur secondary to metabolic alkalosis [16, 17]. Carbonic acid in turn dissociates into bicarbonate () and hydrogen ion (H+) with the latter being removed via kidneys. There is no scientifically validated dosing of IV sodium bicarbonate (as in the management of sodium channel blocker toxicities) but it is typically dosed as 1-2 mEq/kg initially administered in bolus doses (see Table 1) and then may be administered as a continuous IV infusion after dilution in dextrose 5% solution [56]. 12-lead ECG of sodium channel blocker toxicity before and after administration of sodium bicarbonate is presented in Figures 2(a) and 2(b). To neutralize the elevated acid level, sodium bicarbonate will be administered intravenously to regulate the pH balance, and folinic or folic acid will be given to help metabolize the formic acid. Lastly, serious skin injuries can occur in the setting of extravasation of hypertonic bicarbonate solutions, and whenever possible it should be administered through large bore intravenous lines or central venous lines. A brief sketch of the in vivo methanol and ethylene glycol metabolism is presented in Figure 3. However, in some cases, these medications may result in harm including a severe illness and death due to intentional or unintentional overdose or as a result of idiosyncratic drug reaction. Analgesics, including aspirin, were the most common etiology of all drug poisonings in the USA, with salicylate poisoning leading to a fatal outcome in 34 patients out of 2113 deaths reported in 2013 [54]. Key facts • Methanol is a widely available chemical with a range of uses including as a solvent, in chemical synthesis and as a fuel. 2017, Article ID 7831358, 8 pages, 2017. https://doi.org/10.1155/2017/7831358, 1Department of Medicine, University of Kentucky College of Medicine, Lexington, KY, USA, 2University of Kansas Medical Center, Kansas City, KS, USA. 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]. However, according to the consensus guidelines, the therapy with IV sodium bicarbonate should be strongly considered when pH falls below 7.3 with the therapeutic aim of pH normalization. Dialysis can also be used to remove both the methanol and formic acid. It may be necessary to continue sodium bicarbonate after bolus doses in the form of IV infusion by diluting 2-3 ampules in 1 liter of dextrose 5% solution that is nearly isotonic to plasma to decrease the risk of potential rebound deterioration, while, on IV sodium bicarbonate, patients should be monitored for evidence of fluid overload, respiratory status with advanced airway management when indicated, electrolyte abnormalities (hypernatremia, hypokalemia, hypocalcemia), and metabolic alkalosis (potential target pH of 7.5). Sodium Bicarbonate Injection is used for Urine alkalization, Gastric lavage in methanol poisoning, Heart burn, Acidity in the blood, Heartburn and other conditions. Frequency of laboratory testing should be individualized. A. Kriegsman and B. G. Hanna, “Metformin-associated lactic acidosis in a patient with normal renal function,”. There were 52430 exposures to alcohols resulting in 174 fatalities in 2013 [55]. However, with higher dosages, other biochemical alterations may occur such as uncoupling of oxidative phosphorylation in the electron transport chain, resulting in heat release and stimulation of respiratory center in the medulla [23].  |  Patients treated with sodium bicarbonate should be monitored in the intensive care setting with continuous monitoring and reassessment. Irritability and tetany have been associated with sodium bicarbonate-induced alkalosis or hypernatremia. Under extreme conditions such as shock states and impaired ventilation, carbon dioxide may accumulate, leading to worsening acidosis [8, 9]. Ad Hoc committee,”, D. G. Barceloux, G. R. Bond, E. P. Krenzelok, H. Cooper, and J. The infusion rate should be titrated to target a urine pH 7.5–8. IV administration of sodium bicarbonate may result in enhanced urinary excretion of certain chemicals through urinary alkalinization [56]. This site needs JavaScript to work properly. Copyright © 2017 Aibek E. Mirrakhimov et al. Moderate metabolic acidosis: 50 to 150 mEq sodium bicarbonate diluted in 1 L of D5W to be intravenously infused at a rate of 1 to 1.5 L/hour during the first hour. IV sodium bicarbonate should be considered in the cases of suspected sodium channel blocker toxicity associated with hemodynamic and ECG abnormalities, given the very high risk of adverse outcome without aggressive treatment [50]. Fomepizole for the treatment of pediatric ethylene and diethylene glycol, butoxyethanol, and methanol poisonings. Based on the available literature and empiric experience, the IV administration of sodium bicarbonate appears to be beneficial in the management of certain pharmacological toxicities such as sodium channel blockers poisonings, salicylate intoxication, and ingestion of methanol and ethylene glycol. The decrease in the blood pH will favor formation of lipid soluble salicylic acid which easily penetrates blood-brain barrier and undergoes renal reabsorption [55]. [Kidney transplants from donors burdened metabolic acidosis in the course of poisoning with methanol and carbon monoxide]. 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. Sodium bicarbonate is widely used in many clinical situations including cardiac arrest [3, 4] and prevention of contrast-induced renal failure [5] and in patients with different types of metabolic acidosis (such as lactic acidosis and diabetic ketoacidosis) [6], despite limited and controversial evidence of its benefits. Seizures, hypoglycemia and blindness frequently complicate the picture. Uncharged molecules (HS), unlike charged molecules (sal−), can move easily across cellular barriers, including the blood-brain barrier and the epithelium of the renal tubule. However, most of the data originates from case reports, case series, and expert consensus recommendations. Patients with anuric renal failure should not receive IV sodium bicarbonate but rather be evaluated for renal replacement therapy [55]. We will first briefly review the mechanisms of metabolic acidosis related biochemical derangements since some of the overdoses are associated with metabolic acidosis. The suggested regimen for IV sodium bicarbonate is similar to the above-discussed indications. Methyl salicylate exposure in toddlers,”, J. Herres, D. Ryan, and M. Salzman, “Delayed salicylate toxicity with undetectable initial levels after large-dose aspirin ingestion,”, J. Y. Wick, “Aspirin: a history, a love story,”, J. Conversion of methanol to formaldehyde by hepatic enzyme alcohol dehydrogenase triggers the cascade of metabolic events. It is important to keep calcium and potassium within normal range and replete them if low to decrease the risk of cardiac arrhythmias. Tricyclic antidepressants (TCAs) are among the oldest antidepressant medications that may also be used in the management of mood disorders, generalized anxiety disorder, panic disorder, and neuropathic pain [21]. The majority of toxicities arise either as a result of a suicidal attempt or after drinking the toxic alcohol as a substitute for ethanol [57]. [Acute methanol poisoning--a review and a case report].

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. Inhibition of cardiac sodium channels may manifest on the electrocardiogram (ECG) as the prolongation of QRS interval, new onset right axis deviation, deep S wave in lead AVL, tall R wave, and increased R wave to S wave ration in lead AVR and Brugada-like pattern [24–28]. Based on the available literature and empiric experience, the administration of sodium bicarbonate appears to be beneficial in the management of a patient with the above-mentioned toxidromes. ... correction of acidosis with sodium bicarbonate, intubation and mechanical ventilation and It is important to keep calcium and potassium within normal range to decrease the risk of cardiac arrhythmias. Aspirin, which is a major representative of the class, has myriad of indications including cardiovascular diseases, rheumatic diseases, and analgesia [53]. Frequency of laboratory testing and electrocardiographic monitoring should be individualized. 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. The metabolism of methanol is responsible for the transformation of methanol to its toxic metabolites, especially formic acid. Antidotes are available for a range of poisons and can reverse or reduce toxicity, such as naloxone for opioid poisoning, alcohol or fomepizole for toxic alcohols, oxygen for carbon monoxide, chelators for certain metals, sodium bicarbonate for sodium channel blocking agents, methylene blue for methemoglobinemia, and others. Since sodium bicarbonate can cause alkalosis, it is sometimes used to treat aspirin overdoses. Talk with your doctor. Not a substitute for dialysis in severe salicylism; Continuous IV infusion of sodium bicarbonate is indicated even in the presence of mild alkalemia from the early respiratory alkalosis per 2013 ACMT guidelines Lactic acid production may be increased in certain situations via alkalosis dependent activation of 6-phosphofructokinase enzyme [11, 14], and ketone bodies production may be enhanced [15]. toxicity. The pathogenesis of TCA toxicity in regard to sodium channel blockade is fundamental to the understanding of other sodium channel toxicities, as is the therapeutic role of intravenous (IV) sodium bicarbonate. Other potential adverse effects of administered sodium bicarbonate may be related to its chemical features such as supraphysiologic sodium content and osmolality and alkaline pH (comparative chemical features of sodium bicarbonate and commonly used crystalloid solutions to plasma is presented in Table 1). can also bind extra H+ producing carbonic acid. A new approach to the classification of antiarrhythmic drugs based on their actions on arrhythmogenic mechanisms,”, C. E. Stafstrom, “Mechanisms of action of antiepileptic drugs: the search for synergy,”, J. M. Dupuy, M. J. Ostacher, J. Huffman, R. H. Perlis, and A. Metabolic acidosis drives the above reaction to the right and increases the plasma concentration of HS, thereby promoting diffusion across the blood-brain barrier into the CNS. The first report in the English language medical literature of the positive effect of sodium bicarbonate in the management of salicylate-poisoned patient originates in 1948 [55]. Together they comprise perhaps the largest group of cardiotoxic agents. We are committed to sharing findings related to COVID-19 as quickly as possible. Beneficial effects of sodium bicarbonate in the management of methanol and ethylene glycol poisoning are believed to be secondary to the formation and enhanced urinary clearance of less toxic metabolites (formate) [59]. Third, we will review the literature on the role of sodium bicarbonate in the management of sodium channel blocker toxicities. Furthermore, by correcting the systemic acidosis, sodium bicarbonate administration may reduce respiratory drive leading to accumulation of CO2 in the central nervous system and associated adverse neurological sequelae [10]. Methanol poisoning outbreaks . As was discussed above, IV sodium bicarbonate may have serious undesired effects including hypokalemia. Specific treatment for ethylene glycol poisoning includes sodium bicarbonate to correct the metabolic acidosis as indicated, ethanol or fomepizole (Antizol) to competitively inhibit metabolism of ethylene glycol to its more toxic metabolites, and hemodialysis, if indicated, to remove ethylene glycol and glycolic acid. With methanol poisoning, substantial treatment delays may occur because the clinician is falsely reassured by the initial lack of severe symptoms. In patients with salicylate intoxication, the beneficial effects of sodium bicarbonate are mediated by the production of metabolic alkalosis that decreases the amount of lipid soluble salicylate and driving the above reaction to the left resulting in decreased penetration into central nervous system and in increased urinary clearance [56]. Baking soda is white powdery substance that is primarily used for cooking and cleaning purposes. The metabolism of methanol and ethylene glycol disrupts cellular energy metabolism leading to cellular damage [58, 59]. A. Kraut, “Diagnosis of toxic alcohols: limitations of present methods,”, D. G. Barceloux, E. P. Krenzelok, K. Olson, W. Watson, and H. Miller, “American academy of clinical toxicology practice guidelines on the treatment of ethylene glycol poisoning. Mortality associated with methanol has been of great concern time and again. A repeat level may sometimes be obtained two hours after hemodialysis to exclude rebound. The potential mechanisms of sodium bicarbonate administration include high sodium load, development of metabolic alkalosis with resultant decreased tissue penetration of the toxic substance, and its increased urinary excretion, while, on IV sodium bicarbonate, the patients must be monitored for the development of associated side effects including electrolyte abnormalities (hypokalemia, hypocalcemia, and hypernatremia), progression of metabolic alkalosis volume overload, worsening respiratory status (volume overload and increased CO2 production), and worsening metabolic acidosis (paradoxical increase in lactic acid production secondary to the activation of glycolytic enzymes). COVID-19 is an emerging, rapidly evolving situation. [Usefulness of blood formic acid detection in the methanol poisoning in the practice of clinical toxicology department-preliminary assessment]. A. Vale, “Position Paper on Urine Alkalinization,”, J. Schramm A, Rogner B, Weise M, Franz C, Walter A. Serum sodium and osmolality tend to increase which may lead to cellular dehydration and systemic hypervolemia [13]. TCA toxicity may be delayed and patients may initially appear clinically well until decompensation occurs. Indeed, all the reactions are reversible and can go in any direction. A. Vale, “Management of the cardiovascular complications of tricyclic antidepressant: poisoning role of sodium bicarbonate,”, H. Sanaei-Zadeh and A. Ghassemi Toussi, “Resolution of wide complex tachycardia after administration of hypertonic sodium bicarbonate in a patient with severe tricyclic antidepressant poisoning,”, K. Blackman, S. G. A. A simplified view on the bicarbonate chemistry is provided in Figure 1. Aspirin requires an acidic environment for proper absorption, and the basic environment diminishes aspirin absorption in the case of an overdose. 1. The scientific data on the use of sodium bicarbonate in the management of TCA toxicity is predominantly originated from animal studies, case reports, and case series [32, 33]. Con rmation is by determining the plasma levels of methanol. Furthermore, TCA toxicity can cause seizures resulting in persistence of metabolic acidosis and propagation of detrimental metabolic disturbances. Conversion of methanol to formaldehyde by hepatic enzyme alcohol dehydrogenase triggers the cascade of metabolic events. Serum potassium may decrease as a result of potassium shift into the cells in the patient with metabolic acidosis treated with sodium bicarbonate. 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. Despite being an effective class, it is notorious for its narrow therapeutic index and major side effect profile in cases of overdose. Alkalization favors the neutral form of the drug and reducing the amount of active cyclic antidepressants. However, most of the available evidence originates from case reports, case series, and expert consensus recommendations. Omeprazole and Sodium Bicarbonate capsules may help your acid-related symptoms, but you could still have serious stomach problems. Knowledge of the patho-physiological changes that occur in the body after methanol consumption is essential for all practicing doctors. In the vast majority of cases the use of such prescribed medications provides clinical benefit to patients. List of some drugs with sodium channel blocking properties.

An overview of chemical characteristics of commonly used crystalloids is presented in Table 1. Methanol is much more toxic than alcohol. Blood gas analysis (arterial or venous) and chemistry tests should be monitored at least every 4 hours or more frequently if clinically indicated in patients treated with sodium bicarbonate. Sodium Bicarbonate Injection contains Sodium Bicarbonate as an active ingredient. The potential benefits of exogenous intravenous sodium bicarbonate include the correction of metabolic acidosis with its associated detrimental effects. Clinically the effects of sodium channel blockade may present as cardiac arrhythmias and hemodynamic instability [29]. Alkalinization with sodium bicarbonate is an essential component of management of the aspirin-poisoned patient. These end products result in classic features of toxicity such as retinal toxicity caused by methanol and renal injury mediated by oxalic acid. 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. Methanol and ethylene glycol are alcohols commonly used in household solutions such as various cleaners, solvents, machine fluids, and antifreeze solutions [57]. Carbonic anhydrase enzyme facilitates the chemical interaction between CO2 and water producing carbonic acid (H2CO3). However sodium bicarbonate as adjunctive treatment is still controversy. The molecule of bicarbonate in turn binds hydrogen converting into carbonic acid with its subsequent dissociation into carbon dioxide and water. Sodium bicarbonate is the active ingredient in baking soda.
