Alcohol intoxication Wikipedia

Poisoning with methanol, ethylene glycol, and isopropanol present diagnostic and therapeutic challenges to emergency physicians. Toxic alcohol poisonings lead to an elevated osmolar gap and, with the exception of Isopropanol, a metabolic acidosis. In order for the timely initiation of life-saving treatment, emergency physicians need a solid understanding of the pathophysiology, clinical presentation, laboratory workup, and treatment. Teenagers and young adults who drink may be at particular risk for alcohol overdose. Research shows that teens and college-age young adults often engage in binge drinking and high-intensity drinking. Drinking such large quantities of alcohol can overwhelm the body’s ability to break down and clear alcohol from the bloodstream.

• Some people may be able to drink more alcohol than others, with fewer effects.
• The anion gap is neither sensitive nor specific for diagnosing toxic alcohol poisoning.
• This is not always the case because high levels of isopropanol can cause hypotension leading to hypoperfusion and a lactic acidosis.

The symptoms of alcohol intoxication range from mild to severe, depending on how much alcohol a person consumes and how quickly their body metabolizes it. Genetic, psychological, social and environmental factors can impact how drinking alcohol affects your body and behavior. Theories suggest that for certain people drinking has a different and stronger impact that can lead to alcohol use disorder.

Critical Signs and Symptoms of an Alcohol Overdose

It is directly converted to acetone by alcohol dehydrogenase, and acetone itself is a CNS depressant that leads to further sedation (Figure 3). Ingestions are sometime due to an attempt by an individual to replace ethanol when it is unavailable. It does not undergo further metabolism beyond acetone, which is eliminated renally and via the lungs. It is dangerous to assume that an unconscious person will be fine by sleeping it off. One potential danger of alcohol overdose is choking on one’s own vomit. Alcohol at very high levels can hinder signals in the brain that control automatic responses, such as the gag reflex.

• In this mechanism, a constant proportion of the substance is eliminated per unit time and the rate of elimination is directly proportional to the amount of substance present.
• The test is free, confidential, and no personal information is needed to receive the result.
• When you drink, different enzymes in your liver work to break down alcohol so that it can be removed from your body.
• (Classic “moonshine” is a high-concentration ethanol solution distilled from fermented corn).
• Alcohol poisoning can be life threatening and usually requires urgent medical treatment.
• In 2015, 90–94% of cases of methanol poisoning were treated with fomepizole, versus 5–6% treated with ethanol (10).
• Alcohol use disorder includes a level of drinking that’s sometimes called alcoholism.

ROS can interact with lipids, producing lipid peroxidation, leading to formation of reactive molecules such as malondialdehyde (MDA) and 4-hydroxy-2-nonenal (HNE), which can in turn form protein adducts (22). A minor fraction of alcohol metabolism occurs in peroxisomes through catalase-dependent oxidation. Alcohol can also react with glucuronic acid to form ethyl-glucuronide, a soluble, non-volatile conjugate that is readily excreted and detected in body fluids, tissue, sweat, and hair for an extended time following alcohol consumption.

Stages of Alcohol Poisoning

You might not recognize how much you drink or how many problems in your life are related to alcohol use. Listen to relatives, friends or co-workers when they ask you to examine your drinking habits or to seek help. Consider talking with someone who has had a problem with drinking but has stopped. stages of alcohol poisoning In some countries, it is also an offense to serve alcohol to an already-intoxicated person,[52] and, often, alcohol can only be sold by persons qualified to serve responsibly through alcohol server training. People who accidentally consume methanol or isopropyl alcohol may need hemodialysis.

• In the past, alcohol was believed to be a non-specific pharmacological agent affecting many neurotransmitter systems in the brain.[25] However, molecular pharmacology studies have shown that alcohol has only a few primary targets.
• We strive to create content that is clear, concise, and easy to understand.
• What tips the balance from drinking that produces impairment to drinking that puts one’s life in jeopardy varies among individuals.
• One of your liver’s jobs is to break down potentially toxic substances.

Ethanol toxicity results from the ingestion of large amounts of ethanol, usually in the form of alcohol. It affects multiple organ systems in both the acute and chronic phases. This activity outlines the evaluation and management of ethanol toxicity and reviews the interprofessional team’s role in managing patients with this condition. Treatment can vary slightly but generally consists of the same steps whether a person is able to communicate with doctors or is unconscious. “The first thing that we would do when we have a person come into the emergency department for alcohol poisoning is to check their vital signs,” Dr. Farmer says.

Impact on your health

Because these may have varying reliability and may produce different results than the tests used for law-enforcement purposes, the results from such devices should be conservatively interpreted. Ethylene glycol (EG) is a colorless, odorless liquid with a sweet taste. Most poisonings happen through oral ingestion of EG containing liquids, most commonly antifreeze. There are cases of EG poisonings from ethanol substitution, suicide attempts, and accidental ingestions (2, 15).

If they are experiencing an episode of acute alcohol poisoning, their condition could lead to coma and even death if you do not intervene. Consuming too much alcohol too quickly can lead to alcohol poisoning, which is marked by symptoms such as poor coordination, hypothermia, irregular heartbeat, slowed breathing, and unconsciousness.

Risk factors

The anion gap is neither sensitive nor specific for diagnosing toxic alcohol poisoning. Soon after ingestion, the patient may manifest symptoms of toxic alcohol ingestion without an anion gap metabolic acidosis. The metabolic acidosis increases as the toxic alcohols are metabolized to organic acids (formate, oxalate). This creates an inverse relationship between the serum anion gap and osmol gap making the values time-dependent from ingestion, which is often unknown (Figure 4). In addition, the process of metabolism of toxic alcohols to organic acids can be slow.
