Poisoning with alcohol substitutes and technical liquids

Raw alcohol is the product of fermentation of sugar. The method of purification get rectified, used, in particular, for the preparation of alcoholic beverages. In alcohol substitutes, in addition to ethanol, contains large amounts of harmful for the human body of impurities, in particular fusel oils, consisting of higher alcohols (ISO-amyl, butyl, isobutyl, isopropyl and others). Especially toxic amyl alcohols, constituting more than one-third of fusel oils. Compared with ethyl alcohol they have greater narcotic strength and a greater toxicity.
Propyl alcohols are also used as solvents synthetic resins and other substances. According to the General nature of the action on the human body, they remind ethyl alcohol. Known cases of fatal poisoning after taking 300 ml or more poison. They rapidly absorbed from the gastrointestinal tract and after a few minutes after taking appear in the blood and quickly accumulate in the body, particularly the brain. From the body propyl alcohols and their metabolites (propyl and lactic acids, acetone) stand out with your breath, urine, faeces. When blood levels of about 15 per thousand isopropyl alcohol may come coma and death.
On the autopsy of the dead celebrated only signs of quick onset of death. One of the metabolites propyl alcohols, acetone - can be detected in the urine for up to 4 days even after the reception of small amount of isopropyl alcohol.
Butyl alcohol is a colourless liquid with a characteristic alcohol odor. Are used as solvents in perfumery, pharmaceutical industry and other industries, in particular for the manufacture of brake fluid BSC, containing 50 % butyl alcohol. Lethal dose when administered by 200-250 ml, although quite considerable individual variations in sensitivity.
Butyl alcohol gives a narcotic effect, this affected the Central nervous system. If ingestion is developing a momentary state of intoxication that after 3-4 hours enters drowsiness, apathy, and later there is a decrease of view, flicker "flies" in the eyes. Impaired kidney function. In the absence of appropriate treatment usually within 2 days develops a coma and the patient dies.
The autopsy revealed signs quickly actual death; from the internal organs of smell butyl alcohol.
Amyl alcohols - yellowish liquid with a characteristic fusel smell. Poisoning occur both in the reception of raw spirit, and in the use of brake fluid ASC containing 50 % amyl alcohol. When you receive through your mouth lethal dose is about 20-30 ml of pure amyl alcohol. Alcohol intoxication during reception of ethanol even with small amounts of amyl alcohol is of heavy current.
By the nature of the effects on the body amyl alcohols are drugs. First of all affected the Central nervous system and is paralysis of vital centers within the brain stem. After intake of amyl alcohol for several hours circulates in the blood, excreted through the lungs, with the urine. Poisoning is characterized by General weakness, dizziness, nausea, vomiting, burning sensation in the course of the esophagus and stomach pain. After a few minutes noted confusion, oglushennosti, increases cyanosis. Death occurs in a state of severe coma. Picture of poisoning depends to a large extent on the concentration of amyl alcohol drinking liquid. The main morphological changes observed in the gastrointestinal tract. The contents of the stomach has fusel smell.
Meth is used as industrial alcohol. It contains a significant amount of impurities, in particular methyl alcohol that causes its toxicity.
