[2], Signs of ethylene glycol poisoning depend upon the time after ingestion. In other settings, the analysis would also detect parent ethylene glycol, which would qualify for a gold standard diagnosis of … et al. In addition, methanol, ethanol, and ethylene glycol also result in an increase in metabolic acidosis with an increased anion gap, separating them from isopropanol. People therefore must be monitored in an intensive care unit. [71], Ethylene glycol was once thought innocuous; in 1931 it was suggested as being suitable for use as a vehicle or solvent for injectable pharmaceutical preparations. [7][8], The most common source of ethylene glycol is automotive antifreeze or radiator coolant, where concentrations are high. Stage 2 (12 to 36 hours) where signs of "alcohol" poisoning appear to resolve, underlying severe internal damage is still occurring. For ethylene glycol, the preferred method is GC–flame ionization detection (FID). [1] Later symptoms may include a decreased level of consciousness, headache, and seizures. The glycolic acids contribute to central nervous system manifestations, mortality, and a significant metabolic acidosis (anion gap acidosis).3 These metabolites also contribute to significant renal tubular necrosis. [63] Most deaths from ethylene glycol are intentional suicides; deaths in children due to unintentional ingestion are extremely rare.[64]. Litovitz [68] Similarly, White found that adding bittering agents did not decrease the frequency or severity of antifreeze poisonings in children under the age of 5. This unit of measurement was derived by the British Navy when it was suspected that the rum ration was being diluted. Contaminated drinks were produced between July 2019 and … In 53 batches the presence of diethylene glycol or ethylene glycol was detected. Oxalate binds calcium, leading to calcium oxalate crystals, which are deposited in many tissues but are most readily detected in the urine. "[74], In Canada, Environment Canada reports that "in recent years, management practices at Canada’s major airports have improved with the installation of new ethylene glycol application and mitigation facilities or improvements to existing ones. Antifreeze ingestions require rapid and accurate differential diagnosis to prevent fatal outcomes. This antidotal treatment forms the mainstay of management of ethylene glycol poisoning. Most clinical laboratories are equipped to accurately quantitate ethanol levels, mainly by an enzymatic assay on an automated chemistry analyzer platform. [7] The use of these agents is based on theoretical observations and there is limited evidence to support their use in treatment; they may be of particular benefit in people who could be deficient in these vitamins such as those who are malnourished or alcoholic. Devleeschouwer [12], The three main systems affected by ethylene glycol poisoning are the central nervous system, metabolic processes, and the kidneys. [2] Treatment consists of stabilizing the person, followed by the use of an antidote. As the metabolism of ethylene glycol progresses there will be less ethylene glycol and this will decrease the blood ethylene glycol concentration and the osmolal gap making this test less useful. It is eventually excreted in the urine, but supportive therapy for the CNS depression and metabolic acidosis will be required until the ethylene glycol concentrations fall below toxic limits. In this way, Juenke et al4 were able to demonstrate that the modified kinetic parameters applied to the Catachem reagent system accurately distinguished between propylene glycol, 3-butanediol, and ethanol from the true measurement of ethylene glycol. Because hemodialysis will also remove the antidotes from the blood, doses of antidotes need to be increased to compensate. [14] Accumulation of glycolic acid in the body is mainly responsible for toxicity. [15], Ethylene glycol has been shown to be toxic to humans[16] and is also toxic to domestic pets such as cats and dogs. This test measures the level of ethylene glycol in the blood. [7] That is approximately 224 mL (7.6 oz.) [77] Airports that discharge the collected aircraft deicing fluid directly to waters of the U.S. must also meet numeric discharge requirements for chemical oxygen demand. They both have a high boiling point, low vapour pressure, excellent heat transfer abilities and the ability to depress the freezing point of water, but ethylene glycol is a slightly more effective freezing point depressant. 28). Stage 3 (24 to 72 hours) kidney failure is the result of ethylene glycol poisoning. It does not have color or odor. Differential Diagnosis of Alcohol Poisoning. [42], Treatment for antifreeze poisoning needs to be started as soon after ingestion as possible to be effective; the earlier treatment is started, the greater the chance of survival. [18][19][20] In the EU classification of dangerous substances it is 'harmful' (Xn) while more toxic substances are classified as 'toxic' (T) or 'very toxic' (T+). Within 30 minutes of ingestion, they may resemble a person who has had too much to alcohol drink. [7], Fomepizole is a potent inhibitor of alcohol dehydrogenase; similar to ethanol, it acts to block the formation of the toxic metabolites. Brown Ethylene glycol toxicosis is a type of poisoning that occurs after ingestion of antifreeze or other fluids containing the ingredient ethylene glycol. Antifreeze Poisoning (Ethylene Glycol Poisoning) Drugs Scan (Comprehensive Drugs Scan ) Cyanide Poisoning Detection; We are ready to serve you NOW! [26][27], The increased osmolal gap is caused by the ethylene glycol itself. et al. Wu This damage can be identified in a serum biochemistry profile by increases in the metabolites creatinine and BUN (blood urea nitrogen) that are normally removed from the blood by the kidneys. [44] Less commonly it has been used as a means of homicide. [73] Another study found the toxicity to aquatic and other organisms was relatively low, but the oxygen-depletion effect of biodegradation was more serious (p. [17], The orally lethal dose in humans has been reported as approximately 1.4 mL/kg of pure ethylene glycol. Toxicity is manifested by CNS depression (1 to 12 hours after ingestion), cardiopulmonary symptoms (12 to 24 hours after ingestion), and renal damage (24 to 72 hours after ingestion). [3] Those affected are often adults and male. While five of the hospital visits involved kidney problems, doctors never thought to suspect ethylene glycol poisoning, prosecutors said. However, these instruments and the needed expertise are not readily available in most clinical laboratories. Ethylene glycol poisoning is poisoning caused by drinking ethylene glycol. [55][56][57] Many cases of poisoning are the result of using ethylene glycol as a cheap substitute for alcohol or intentional ingestions in suicide attempts. Juenke Ethylene glycol blood test. ANTIFREEZE POISONING… VODKA AS AN ANTIDOTE? In this situation stabilization of the person including airway management with intubation should be performed in preference to gastrointestinal decontamination.
