sodium bicarbonate methanol poisoning
IV administration of sodium bicarbonate may result in enhanced urinary excretion of certain chemicals through urinary alkalinization [56]. Frequency of laboratory testing should be individualized. 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. Intravenous sodium bicarbonate therapy should be considered if the blood pH is below 7.2. 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. Review articles are excluded from this waiver policy. B. Posner and F. Plum, “Spinal-fluid pH and neurologic symptoms in systemic acidosis,”, M.

Dialysis can also be used to remove both the methanol and formic acid. TCAs were responsible for approximately 58% of all antidepressant medications related fatal toxicities in 2013 [22]. 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. Methanol toxicity can have devastating visual consequences and retinal specialists should be aware of the features of this toxic optic neuropathy. Patients with anuric renal failure should not receive IV sodium bicarbonate but rather be evaluated for renal replacement therapy [55]. 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. [Acute methanol poisoning--a review and a case report]. The metabolism of methanol and ethylene glycol disrupts cellular energy metabolism leading to cellular damage [58, 59]. An overview of chemical characteristics of commonly used crystalloids is presented in Table 1. 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. Aspirin requires an acidic environment for proper absorption, and the basic environment diminishes aspirin absorption in the case of an overdose. These cardiotoxins are responsible for more fatal dysrhythmias annually than any other class of medications. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. 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]. The manifestations begin as early as 30 minutes and progress to decompensated metabolic acidosis in about 12 hours, if left untreated. 12-lead ECG of sodium channel blocker toxicity before and after administration of sodium bicarbonate is presented in Figures 2(a) and 2(b). However, in cases of excessive administration (intentional or not), sodium channel blockade may lead to serious cardiac dysfunction. Methanol, or wood alcohol, is not an acceptable alternative to ethanol in hand sanitizers as the chemical compound is highly toxic and commonly used … 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]. 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. Alkalinization with sodium bicarbonate is an essential component of management of the aspirin-poisoned patient. Indeed, all the reactions are reversible and can go in any direction. Patients treated with sodium bicarbonate should be monitored in the intensive care setting with continuous monitoring and reassessment. In the vast majority of cases the use of such prescribed medications provides clinical benefit to patients. Serum potassium may decrease as a result of potassium shift into the cells in the patient with metabolic acidosis treated with sodium bicarbonate. 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). 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]. Schramm A, Rogner B, Weise M, Franz C, Walter A. As was discussed above, IV sodium bicarbonate may have serious undesired effects including hypokalemia. 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).

Omeprazole and Sodium Bicarbonate capsules can cause serious side effects, including: A type of kidney problem (acute tubulointerstitial nephritis). 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. Clipboard, Search History, and several other advanced features are temporarily unavailable. 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. We will first briefly review the mechanisms of metabolic acidosis related biochemical derangements since some of the overdoses are associated with metabolic acidosis. Knowledge of the patho-physiological changes that occur in the body after methanol consumption is essential for all practicing doctors. A list of some of the commonly used medications possessing sodium channel blocking activities is presented in Table 2. NIH The final products of methanol and ethylene glycol metabolism are formic acid and oxalic acid, respectively [57]. 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]. Methanol toxicity is poisoning from methanol, characteristically via ingestion. The authors declare that they have no conflicts of interest regarding the publication of this paper. Laboratory results were significant for a severe metabolic acidosis, a serum osmolality of 465 and serum methanol level of 493 mg/dl. B. 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]. 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.

Gillman, “Tricyclic antidepressant pharmacology and therapeutic drug interactions updated,”, K. H. Choi and K.-U. Administration of sodium bicarbonate should be used with caution in a patient with oliguric/anuric renal failure (which is classically seen in severe ethylene glycol toxicity). Metformin toxicity is another instance where sodium bicarbonate may be used [60]. Conversion of methanol to formaldehyde by hepatic enzyme alcohol dehydrogenase triggers the cascade of metabolic events. Sodium Bicarbonate Injection is used for Urine alkalization, Gastric lavage in methanol poisoning, Heart burn, Acidity in the blood, Heartburn and other conditions. Shen, M. B.

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]. 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. However, most of the available evidence originates from case reports, case series, and expert consensus recommendations. Adverse reactions to commonly prescribed medications and to substances of abuse may result in severe toxicity associated with increased morbidity and mortality. 2010 Jun;48(5):401-6. doi: 10.3109/15563650.2010.495347. Symptoms may include a decreased level of consciousness, poor or no coordination, vomiting, abdominal pain, and a specific smell on the breath. 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. Sodium bicarbonate (NaHCO3) is one of the few pharmacological agents aiming to mimic the endogenous effects of . A brief sketch of the in vivo methanol and ethylene glycol metabolism is presented in Figure 3. 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. Drugs and toxins that act as sodium channel antagonists include agents listed in List 1.

The use of sodium bicarbonate is also common as methanol can lead to acidosis. 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]. 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. Seizures, hypoglycemia and blindness frequently complicate the picture. 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. 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]. Talk with your doctor. Third, we will review the literature on the role of sodium bicarbonate in the management of sodium channel blocker toxicities. 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. 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. Methanol is not found in Australian methylated spirits. 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 HHS 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]. An overview of the endogenous bicarbonate metabolism. | 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. 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. When evaluating the toxicity of baking soda, there are two parts to consider: the sodium; and the bicarbonate, which effects the pH (acid level) of body fluids. 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. Differences between arterial and central venous blood,”, J. In conclusion, the literature on the use of sodium bicarbonate in the management of sodium channel blocker toxicities is limited to animal research and case series; randomized trials are precluded due to ethical reasons. This article elucidates the clinical presentation and emergency management of these cases under the framework of basic physiological and biochemical phenomena after methanol exposure. | Lukasik-Głębocka M, Sommerfeld K, Kapala M, Adamek R, Panieński P, Zielińska-Psuja B, Samborski W.

Clin Toxicol (Phila). 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). Patients with salicylate toxicity typically present with tinnitus, gastrointestinal complications (nausea, vomiting, bleeding, and liver toxicity), hyperthermia (via uncoupling of oxidative phosphorylation), pulmonary edema, and mixed acid-base disorder (high anion gap metabolic acidosis and respiratory alkalosis via stimulation of respiratory center in the brain stem) [55]. A simplified view on the bicarbonate chemistry is provided in Figure 1. 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. Please enable it to take advantage of the complete set of features! Methanol poisoning may cause coagulopathy, so be careful if anticoagulation is being used to facilitate dialysis. 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. Sodium channels are essential ion channels responsible for transcellular sodium influx, primarily in cardiac and neurological tissue [18]. 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). toxicity. 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. There were 52430 exposures to alcohols resulting in 174 fatalities in 2013 [55]. Decreased vision may start as early as twelve hours after exposure. 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. B. Gorin, J. Yacoub, and N. E. Madias, “Assessing acid-base status in circulatory failure. Constituents and characteristics of commonly used crystalloids and plasma. 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. Brown, and G. J.

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. Frequency of laboratory testing and electrocardiographic monitoring should be individualized. Despite being an effective class, it is notorious for its narrow therapeutic index and major side effect profile in cases of overdose. Methanol and ethylene glycol are alcohols commonly used in household solutions such as various cleaners, solvents, machine fluids, and antifreeze solutions [57]. 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. Together they comprise perhaps the largest group of cardiotoxic agents. In the USA, at least 34% of the population regularly takes at least one prescription medication [1]. ASA toxicity impairs glucose metabolism; Alkalinization of plasma and urine. It is important to keep calcium and potassium within normal range and replete them if low to decrease the risk of cardiac arrhythmias. 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). 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. The metabolism of methanol is responsible for the transformation of methanol to its toxic metabolites, especially formic acid. Clinically the effects of sodium channel blockade may present as cardiac arrhythmias and hemodynamic instability [29]. 2017 May;69(5):696-700. doi: 10.1053/j.ajkd.2016.10.029. TCA toxicity may be delayed and patients may initially appear clinically well until decompensation occurs. The concurrence of cases from a particular area raises doubts about methanol as the culprit. To understand the basic pathogenesis of methanol and ethylene glycol toxicity, it is important to review briefly the metabolism in vivo. Animal research supports the beneficial effects of sodium bicarbonate in case of thioridazine toxicity [49]. Van Geijlswijk, D. Tjan, and A. 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. 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). 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. The potential benefits of exogenous intravenous sodium bicarbonate include the correction of metabolic acidosis with its associated detrimental effects. 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]. 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]. 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. A repeat level may sometimes be obtained two hours after hemodialysis to exclude rebound. Sodium bicarbonate is the active ingredient in baking soda. When administered, sodium bicarbonate dissociates into a molecule of sodium and bicarbonate.

The major mechanism of action of aspirin is mediated via inhibition of cyclooxygenase enzyme, resulting in decreased production of thromboxane A2 and various prostaglandins [53]. Salicylic acid (HS) is a weak acid that exists in a charged (deprotonated, sal−) and uncharged (protonated, H+) form: H+ + sal− ⇔ HS. The development of hypokalemia is particularly detrimental to the patients with salicylate-mediated toxicity because of increase in hydrogen ion urinary excretion resulting in more acidic urine and greater salicylate reabsorption and thus, should be aggressively corrected [55, 56]. Carbon dioxide under normal conditions (intact lung perfusion and ventilation) is exhaled, maintaining delicate acid-base equilibrium. 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. 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].
