Epidemiology of acute poisonings with gammahydroxybutyric acid in Saint Petersburg (according to data of a multidisciplinary hospital)

It was found that for the period from X.2017 to III.2020 among patients admitted to a multidisciplinary hospital with acute poisoning with narcotic drugs (NV) and psychoactive substances (PAS), persons in whose biological environment GHB was detected ranged from 20,1 to 40,1%. The prevalence of acute poisoning of the studied class in male patients (86%) of working age (the average age was 34,2 ± 2,9 year) was proved. The patients used 1,4-butanediol (1,4-BD) as a toxicant (GHB) in 95% of cases. The dynamics of the incidence of acute GHB poisoning over a three-year period was uneven, with peaks of maximum values in August (Me = 168), March (Me = 90), and September (Me = 103) and low rates - in June (Me = 71) and total upward trend - y = 6,6573x = 343,23, R2 = 0,053. The severity of acute GHB poisoning at the time of admission on the PSS scale was 2,2 ± 0,57 points, PSSSP – 22,7 ± 2,17 points. Acute GHB poisoning was characterized by signs of toxic-hypoxic encephalopathy, clinically manifested in the form of depression of consciousness to the level of deep stunning - coma. The duration of inpatient treatment of patients was (1,76 ± 3,7, min = 1, max = 35) days, the period of stay in the intensive care unit (ICU) was 4,2 ± 0,4 hours. The increase in hospitalization (more than a day) was due to somatic complications of acute poisoning (nasocomial pneumonia, systemic rhabdomyolysis, acute renal failure) - in 14% of cases, severe withdrawal syndrome with delirious confusion - in 3,5% of cases. The post-intoxication period was characterized by moderate withdrawal symptoms – 13,7 ± 2,1 points, according to the CIWA-Ar scale. The delirious syndrome was characterized by a protracted course (9,5 ± 1,2 days), an atypical clinical picture, and metabolic disorders. The mortality rate due to acute GHB poisoning increased from 0,09 to 0,22%, in 2019 the cause of death was pronounced degenerative changes in internal organs and varying degrees of severity of microcirculation disorders.
