Sodium Bicarbonate Injection may also be used for purposes not listed in this medication guide. This article elucidates the clinical presentation and emergency management of these cases under the framework of basic physiological and biochemical phenomena after methanol exposure. Animal research supports the beneficial effects of sodium bicarbonate in case of thioridazine toxicity [49]. 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. 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]. The molecule of bicarbonate in turn binds hydrogen converting into carbonic acid with its subsequent dissociation into carbon dioxide and water. B. A. Vale, “Position Paper on Urine Alkalinization,”, J. The management of the toxicities mentioned above is complicated, requiring additional measures than sodium bicarbonate alone. Carbonic anhydrase enzyme facilitates the chemical interaction between CO2 and water producing carbonic acid (H2CO3). However, in cases of excessive administration (intentional or not), sodium channel blockade may lead to serious cardiac dysfunction. The potential mechanisms of sodium bicarbonate include high sodium load and the development of metabolic alkalosis with resultant decreased tissue penetration of the toxic substance with subsequent increased urinary excretion. Sodium channels are essential ion channels responsible for transcellular sodium influx, primarily in cardiac and neurological tissue [18]. toxicity.

List of some drugs with sodium channel blocking properties. Lee, “Serial monitoring of lead aVR in patients with prolonged unconsciousness following tricyclic antidepressant overdose,”, F. Eyer, J. Stenzel, T. Schuster et al., “Risk assessment of severe tricyclic antidepressant overdose,”, J. Veris-van Dieren, L. Valk, I. 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. Along with water, … NLM Sodium bicarbonate possesses the ... (valium) cyclic antidepressants (amytriptayine), organophosphates, methanol (Methyl alcohol is a cheap and potent adulterant of illicit liquors) Diphenhydramine (Benedryl), Beta blockers (propanalol) Barbiturates, and Salicylates (Aspirin). Since sodium bicarbonate can cause alkalosis, it is sometimes used to treat aspirin overdoses. [Usefulness of blood formic acid detection in the methanol poisoning in the practice of clinical toxicology department-preliminary assessment]. The high sodium load increases the electrochemical gradient across cardiac cell membranes, potentially attenuating the TCA-induced blockade of sodium channels [29, 30]. 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. 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. Carbon dioxide under normal conditions (intact lung perfusion and ventilation) is exhaled, maintaining delicate acid-base equilibrium. 1. Talk with your doctor. 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]. Frequency of laboratory testing and electrocardiographic monitoring should be individualized. However, most of the data originates from case reports, case series, and expert consensus recommendations. 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]. It is chemically known as sodium bicarbonate and has a variety of other applications; Baking soda is used for baking breads and cakes. 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.  |  The goal of this article is to review the data and evidence on the use of sodium bicarbonate in the management of some pharmacological overdoses. Adverse reactions to commonly prescribed medications and to substances of abuse may result in severe toxicity associated with increased morbidity and mortality.

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. 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]. 2017 May;69(5):696-700. doi: 10.1053/j.ajkd.2016.10.029.

In the USA, at least 34% of the population regularly takes at least one prescription medication [1]. 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. 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. Carbonic acid in turn dissociates into bicarbonate () and hydrogen ion (H+) with the latter being removed via kidneys. Sodium Bicarbonate Injection is used for Urine alkalization, Gastric lavage in methanol poisoning, Heart burn, Acidity in the blood, Heartburn and other conditions. Irritability and tetany have been associated with sodium bicarbonate-induced alkalosis or hypernatremia. Intravenous sodium bicarbonate therapy should be considered if the blood pH is below 7.2. Patients with oliguric/anuric renal failure and advanced decompensated heart failure should not receive sodium bicarbonate. An overview of the endogenous bicarbonate metabolism.

The concurrence of cases from a particular area raises doubts about methanol as the culprit. As was discussed above, IV sodium bicarbonate may have serious undesired effects including hypokalemia. Methanol toxicity can have devastating visual consequences and retinal specialists should be aware of the features of this toxic optic neuropathy. Decreased cardiac oxygen supply and arterial vasoconstriction may also occur secondary to metabolic alkalosis [16, 17]. Bicarbonate is an essential chemical regulating the acid-base balance acting as a buffer [2]. Laboratory results were significant for a severe metabolic acidosis, a serum osmolality of 465 and serum methanol level of 493 mg/dl. B. Mowry, D. A. Spyker, L. R. Cantilena Jr., N. McMillan, and M. Ford, “2013 annual report of the American Association of Poison Control Centers' National Poison Data System (NPDS): 31st annual report,”, G. F. O'Malley, “Emergency department management of the salicylate-poisoned patient,”, A. T. Proudfoot, E. P. Krenzelok, and J. Serum sodium and osmolality tend to increase which may lead to cellular dehydration and systemic hypervolemia [13]. An overview of chemical characteristics of commonly used crystalloids is presented in Table 1. Laboratory testing and diagnosis are based on the presence of high anion gap metabolic acidosis, the presence of a serum osmolal gap (the difference between measured and calculated osmolality > 10), and measuring the levels of toxic alcohols (used for confirmation; typically, this testing is not time sensitive, and the treatment should not be withheld in any patient suspected of having toxic alcohol ingestion). Drugs and toxins that act as sodium channel antagonists include agents listed in List 1. Despite being an effective class, it is notorious for its narrow therapeutic index and major side effect profile in cases of overdose. We will first briefly review the mechanisms of metabolic acidosis related biochemical derangements since some of the overdoses are associated with metabolic acidosis. Third, we will review the literature on the role of sodium bicarbonate in the management of sodium channel blocker toxicities. Methanol is not found in Australian methylated spirits. Shen, M. B.

Griffel, “Difference in acid-base state between venous and arterial blood during cardiopulmonary resuscitation,”, H. J. Adrogue, N. Rashad, A. A brief sketch of the in vivo methanol and ethylene glycol metabolism is presented in Figure 3. However, it seems very unlikely that randomized controlled trials assessing the impact of sodium bicarbonate will be performed due to ethical concerns. 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]. A simplified view on the bicarbonate chemistry is provided in Figure 1. Conversion of methanol to formaldehyde by hepatic enzyme alcohol dehydrogenase triggers the cascade of metabolic events. 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. CO2 penetrates cellular membranes easily, and through this ability may exacerbate intracellular acidosis. Fundoscopic examination and arterial blood gas analysis are the key diagnostic elements. It is important to note that symptomatic hypocalcemia should be corrected (the routine correction of asymptomatic hypocalcemia is discouraged because of the possible increase in the formation of calcium oxalate crystals in ethylene glycol toxicity). 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.  |  When ingested, both methanol and ethylene glycol undergo an initial biochemical reaction catalyzed by alcohol dehydrogenase (the same enzyme metabolizing ethanol) converting the parent alcohol into formaldehyde and glycolaldehyde, respectively. Below we will review the utility and likely mechanisms of sodium bicarbonate in the management of certain pharmacological toxicities: sodium channel blockers, salicylates, methanol and ethylene glycol poisonings, and, finally, miscellaneous pharmacological toxicities. Continue dialysis until alcohol level is <20 mg/dL and acidosis resolves. Van Zanten, “Coma with ECG abnormalities: consider tricyclic antidepressant intoxication,”, A. Meert, N. Vermeersch, R.

Thomas, and J. 2 The minimal poisoning dose of methanol in humans has been assumed to be 100 mg/kg body weight and about 30 mL of pure methanol may cause death. Dialysis can also be used to remove both the methanol and formic acid. Under extreme conditions such as shock states and impaired ventilation, carbon dioxide may accumulate, leading to worsening acidosis [8, 9]. 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]. 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 … Review articles are excluded from this waiver policy. USA.gov. The manifestations begin as early as 30 minutes and progress to decompensated metabolic acidosis in about 12 hours, if left untreated. Indeed, all the reactions are reversible and can go in any direction. 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. Alkalinization with sodium bicarbonate is an essential component of management of the aspirin-poisoned patient. However, the role of sodium bicarbonate in the management of acute acidosis remains controversial and may even be associated with potential side effects and complications such as volume overload, metabolic alkalosis, hypercapnia, hypokalemia, hypernatremia and hyperosmolality, and ionized hypocalcemia [6, 7]. Clinical presentations of methanol and ethylene glycol overlap, including central nervous system (CNS) symptoms such as headache, altered mental status, and seizures. Profound acidemia is corrected with sodium bicarbonate Bicarbonate 1-2mEq/kg IV bolus to attain pH = 7.45-7.50 Follow by infusion of 150mEq/L in D5 at 1.5-2x maintenance fluid rate Con rmation is by determining the plasma levels of methanol. HHS 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]. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. 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]. These cardiotoxins are responsible for more fatal dysrhythmias annually than any other class of medications. Sodium bicarbonate has also been used in the treatment of tricyclic antidepressant overdose. Copyright © 2017 Aibek E. Mirrakhimov et al. Second, we will discuss the mechanism of action, potential side effects, and typical dosing of sodium bicarbonate. Ad Hoc committee,”, D. G. Barceloux, G. R. Bond, E. P. Krenzelok, H. Cooper, and J. Nevertheless, it is important to keep in mind that IV sodium bicarbonate represents only a single tool in the management of these toxicities and additional mechanisms of toxicity may account for protean clinical manifestations of these poisonings. 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]. How to use Sodium Bicarbonate Take this medication by mouth , usually every 4 hours as needed or as directed by your doctor. Methanol poisoning or intoxication is rare and often occurs after suicidal or accidental oral ingestion of methanol-containing agents, or after consumption of adulterated or "moonshine" alcoholic beverages 1,2. Methanol toxicity poses a significant public health problem in developing countries, and in Southeast Asia, where the most common source of poisoning is via adulterated liquor in local drinks. Carbon dioxide (CO2) is a major byproduct of energy metabolism in living organisms and a conjugate acid. 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 We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. 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).

Blood gas analysis every two hours is indicated for monitoring to prevent severe alkalemia (arterial pH > 7.60) [55, 56]. Schramm A, Rogner B, Weise M, Franz C, Walter A. Other medications such as antiarrhythmics [36–38], non-TCA antidepressants [39, 40], antiepileptic medications [41–43], cyclobenzaprine [43, 44], propranolol [45], cocaine [46], and certain antihistamines [47] may produce similar ECG and clinical manifestations with favorable response to similarly administered IV sodium bicarbonate. Salicylates are a group of pharmacological agents that include aspirin, bismuth salicylate, and local skin preparations such as salicylic acid and methyl salicylate (topical preparations that rarely cause toxicity if used in an excessive amount or in patients with skin damage leading to increased absorption) [51, 52]. 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. Brown, and G. J. Wilkes, “Plasma alkalinization for tricyclic antidepressant toxicity: a systematic review,”, C. Köppel, U. Oberdisse, and G. Heinemeyer, “Clinical course and outcome in class ic antiarrhythmic overdose,”, E. Bou-Abboud and S.

Clin Toxicol (Phila). 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. Patients with anuric renal failure should not receive IV sodium bicarbonate but rather be evaluated for renal replacement therapy [55].  |  Omeprazole and Sodium Bicarbonate capsules may help your acid-related symptoms, but you could still have serious stomach problems. 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 administration of sodium bicarbonate may result in enhanced urinary excretion of certain chemicals through urinary alkalinization [56]. Constituents and characteristics of commonly used crystalloids and plasma. 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]. Furthermore, TCA toxicity can cause seizures resulting in persistence of metabolic acidosis and propagation of detrimental metabolic disturbances. 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]. Knowledge of the patho-physiological changes that occur in the body after methanol consumption is essential for all practicing doctors. The suggested regimen for IV sodium bicarbonate is similar to the above-discussed indications. 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. Seizures, hypoglycemia and blindness frequently complicate the picture. Clipboard, Search History, and several other advanced features are temporarily unavailable. 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). Patients treated with sodium bicarbonate should be monitored in the intensive care setting with continuous monitoring and reassessment. It is important to keep in mind that because of its anticholinergic properties, the absorption of the TCA may be delayed (due to delayed gastrointestinal motility); these patients should be closely monitored, and, in cases of reemerging symptoms, sodium bicarbonate and other therapies must be timely administered. Frequency of laboratory testing should be individualized. However sodium bicarbonate as adjunctive treatment is still controversy. To understand the basic pathogenesis of methanol and ethylene glycol toxicity, it is important to review briefly the metabolism in vivo. Retinal toxicity and blindness are more specific for methanol; acute kidney injury and hypocalcemia are more typical for ethylene glycol intoxication. 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]. Symptoms may include a decreased level of consciousness, poor or no coordination, vomiting, abdominal pain, and a specific smell on the breath. In this article, we review the data regarding the impact of systemic sodium bicarbonate administration in the management of certain poisonings including sodium channel blocker toxicities, salicylate overdose, and ingestion of some toxic alcohols and in various pharmacological toxicities. The authors declare that they have no conflicts of interest regarding the publication of this paper. 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. These end products result in classic features of toxicity such as retinal toxicity caused by methanol and renal injury mediated by oxalic 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). Methanol poisoning may cause coagulopathy, so be careful if anticoagulation is being used to facilitate dialysis. In conclusion, the data on the role of sodium bicarbonate in the management of the above-listed medications is even more limited and cannot be recommended as a first line. 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. As is the case with any treatment involving IV sodium bicarbonate, administration necessitates frequent monitoring of metabolic parameters (serum electrolytes and renal function), cardiopulmonary, and renal status of the patient.
