[Acute severe oral poisoning with 1,4-butandiol and ethanol with the development of coma]. / Ostroe tyazheloe peroral'noe otravlenie 1,4-butandiolom i etanolom s razvitiem komatoznogo sostoyaniya.

A case of acute oral poisoning by 1.4-butanediol, complicated by the development of severe hypoxia in a 34-year-old patient actively engaged in bodybuilding, is presented. The psychoactive substance was used by the patient to increase sexual activity and physical stamina. The duration of systematic daily intake was 4 months. The toxicogenic stage of acute poisoning was caused by a single dose of 50 ml of undiluted 13% 1.4-butanediol together with ethanol, manifested by convulsive syndrome, depression of consciousness to the level of coma II, acute respiratory failure with aspiration syndrome, respiratory acidosis (pH 7.22; partial pressure carbon dioxide 61.2 mm Hg), lactic acidosis up to 7 mmol / L, hyperammonemia up to 240 µmol / L, cerebral edema (decrease in white matter density to 21.6 ± 1.7 HU units), loss of vascular tone resistance (pareso arterioles) and a significant increase in cerebral blood flow rate to 115 ± 20.1 ml / 100 g per minute, increasing the volume of extracellular fluid (+ 130% of the proper volumes). Intensive therapy was complex, including infusion and detoxification therapy, correction of acid-base disorders, hypoxic disorders by using a substrate antihypoxant (Cytoflavin) in a daily dosage of 0.57 ml / kg body weight daily, for 9 days. The article discusses the toxicokinetics and toxicodynamics of 1.4-butanediol, radiation diagnostics and the clinical picture of acute poisoning, the features of its course, and pathogenetic approaches to therapy.
