Prevalence, structure, frequency of complications and outcomes of treatment of rhabdomyolysis in acute exogenous intoxication in a multidisciplinary hospital

Abstract

Introduction. The prevalence of rhabdomyolysis among people admitted to the hospital due to acute poisoning reaches, according to various foreign sources, from 30 to 40%. In 60% of cases, the development of rhabdomyolysis in adult patients is associated with acute exogenous intoxication. Currently, data on the prevalence, structure and outcomes of treatment of rhabdomyolysis in toxicological patients are mainly presented by the results of foreign clinical and epidemiological studies. The aim is to study the prevalence, structure, frequency of complications and outcomes of treatment of rhabdomyolysis in acute exogenous intoxication in a multidisciplinary hospital. Material and methods. The study included 1,363 patients who were treated from 2017 to 2020 with acute exogenous intoxication. During the study, 98 patients with rhabdomyolysis were selected from the general group. The frequency of poisoning with various toxicants was analyzed, the effects of which led to the development of rhabdomyolysis in acute exogenous intoxication. The incidence of acute kidney injury (AKI) was detected, the outcomes of acute poisoning treatment, the duration of inpatient treatment were determined, and a comparative analysis was carried out between groups of patients with rhabdomyolysis in acute exogenous intoxication (n=98) and without it (n=1265). Results. The prevalence of rhabdomyolysis among patients hospitalized for acute poisoning was 7%. The main reason for the development of rhabdomyolysis was the use of narcotic drugs - 87% of cases. The development of rhabdomyolysis in acute exogenous intoxication in 59.2% of cases is accompanied by the occurrence of AKI, which is significantly higher than among patients without rhabdomyolysis (11.6%). The occurrence of rhabdomyolysis in toxicological patients increases hospital mortality from 6.1 to 10.2%, as well as the duration of inpatient treatment and intensive care by 5.2 and 3.3 days, respectively. Limitations. The study was conducted based on only one multidisciplinary hospital in Moscow in the period from 2017 to 2020. Conclusion. Rhabdomyolysis is a serious complication of acute poisoning, the development of which significantly worsens the outcomes of treatment of patients with a toxicological profile, which requires the development of effective methods for the prevention, diagnosis and treatment of rhabdomyolysis in acute exogenous intoxication.
