The aim of the study. Obtaining new data on the pathogenesis of endotoxicosis (ET) in the rehabilitation period of acute poisoning by assessing the conjugacy of hemorheology (HR) disorders with the development of ET. Material and methods. To obtain new information about the pathogenesis of acute poisoning in the rehabilitation period in 145 patients with severe acute poisoning with psychopharmacological agents (PFAp) due to the addition of pneumonia, neurotoxicants (NTp) with the development of toxic hypoxic encephalopathy and corrosive substances (CSp) with deep and widespread burns of the mucous membranes of the gastrointestinal tract, a pair correlation analysis of the block structure of the obtained correlation matrix was undertaken, establishing the relationship between the two indicators, as well as a canonical correlation analysis revealing the nature of the statistical relationship between groups of indicators, with the calculation of the canonical correlation coefficient. Results. As a result, statistically significant correlations were established between the indicators HR (viscometric, aggregation and indicators hemostasis) and ET (total and effective albumin concentration, the level of medium molecular weight peptides, the content of leukocytes, lymphocytes, neutrophils and circulating immune complexes detected in the blood, and his integral indicators) (-0.32-0.48 for PFAp, 0.29-0.35 for NTp and 0.28-(-0.51) for CSp), as well as statistically significant values canonical correlation coefficients, which indicated the development of ET due to disorders of HR. Limitations. The study was performed on laboratory data obtained during the examination of patients with acute poisoning, and therefore has no restrictions for the further use of this methodological approach in clinical trials. Conclusion. The obtained data can serve to optimize the treatment of ET in this pathology by targeted therapeutic effects on parameters of HR (on viscosity and hemostasis in PFAp and NTp, and in CSp, in addition, on aggregation).
The effective care for patients with self-poisoning with antihypertensive and antiarrhythmic drugs is associated with taking into account both clinical and adverse social, psychological and environmental stress factors. To identify their specifics, a retrospective analysis of 120 medical records and a clinical and psychological examination of 20 patients with antihypertensive and antiarrhythmic drugs self-poisoning and a comparison group of 34 patients with selfpoisoning with psychotropic drugs were carried out. It has been shown that the risk group for re-suicide in self-poisoning with antihypertensive and antiarrhythmic drugs is about 30% of patients. Risk factors are depressive symptoms that persist before discharge from the hospital, as well as dysfunctional personality traits (perfectionism in the form of increased preoccupation with the assessments of other people and frequent unfavorable comparisons with them, experiencing loneliness and isolation, increased impulsivity and a feeling of hostility from others) and unproductive ways of coping with stress (ruminative thinking or repetitive unpleasant and unproductive thoughts about anergy, lack of strength and loneliness). The results of the study and the developed psychodiagnostic complex can be used to identify targets for urgent psychological assistance and screening for the risk of re-suicide.
AIM OF THE STUDY To study benzodiazepine poisoning in geriatric patients compared to patients of working age.MATERIAL AND METHODS We examined 82 patients with benzodiazepine poisoning, hospitalized in the Department of Acute Poisoning and Somatopsychiatric Disorders of the N.V. Sklifosovsky Research Institute for Emergency Medicine in 2020–2021, which were divided into age categories: young (18–44 years old), middle (45–59 years old) and older (over 60 years old) age. The presence of benzodiazepines in urine was confirmed by immunochromatographic analysis and gas chromatography–mass spectrometry (GC-MS). The concentration of phenazepam in the blood and urine was determined in 45 patients by GC-MS. Statistical processing of the material was performed using the IBM program SPSS Statistics 27.0. The median (Me), 25th and 75th percentiles were determined. The comparison of quantitative data was performed using non-parametric criteria, the level of significance was taken as p<0.05.RESULTS It was found that acute phenazepam poisoning prevailed in all age groups (90% of patients). Among young and middle-aged patients, moderate and deep stunning (GCS score 12–14) prevailed, and in older people moderate and severe poisoning prevailed (GCS score 3–12), with no statistically significant differences in blood concentrations of phenazepam between the groups. In patients of the older age group with benzodiazepine poisoning, compared to people of working age, the development of respiratory failure was statistically significantly more frequent — 13.8-fold, pneumonia — 12.6-fold, vein thrombosis of the lower extremities — 7.8-fold, trophic skin changes — 29-fold. The duration of treatment in older patients with benzodiazepine poisoning was 3.5-fold higher than in young and middle-aged patients, mortality in the older age group was 41%.CONCLUSION The course of acute poisoning with benzodiazepines, including phenazepam, in the elderly and senile age differs in comparison with persons of working age with a high incidence of complications and adverse outcomes.
BACKGROUND Currently, despite the optimization of diagnostic methods in order to predict the development of liver damage, improvement of treatment protocols, paracetamol poisoning is a serious problem in medicine, being the most common cause of acute liver failure worldwide.AIM OF STUDY To determine the indications for the use of acetylcysteine in paracetamol poisoning and evaluate the effectiveness of the 21-hour protocol for its administration.MATERIAL AND METHODS We examined 20 patients with acute paracetamol poisoning (15 women and 5 men), the median age was 21.5 (19.8–32.3) years. ALT and AST were assessed during the entire period of stay in the hospital, the time period from the moment of taking paracetamol to hospitalization and the beginning of the administration of ACC, the concentration of paracetamol in the blood, and mortality. According to the level of ALT and AST in the blood, the patients were divided into 2 groups: Group I consisted of 14 patients, in whom the concentration of ALT and AST during the entire observation period did not exceed 50 U/L; in Group II (6 patients), an increase in the level of ALT and AST in the blood of more than 50 U/L was observed. To assess the risk of liver lesion, the Rumack-Matthew nomogram was used. To compare the concentrations of paracetamol in the blood of patients, the paracetamol index was used.RESULTS It was found that in 10 patients with a high risk of liver damage, who were treated with a 21-hour regimen of ACC administration, no hepatotoxic effect was found. The use of ACC according to a 21-hour protocol in patients with initially elevated ALT and AST levels of more than 50 U/L (n = 4) (25%) led to a rapid positive dynamics of laboratory and clinical parameters. It was found that in 2 patients, despite the introduction of ACC, the development of liver damage was observed. At the same time, the level of paracetamol in their blood was 6.6 and 10.6 fold higher than the “therapeutic” line of the nomogram, and the time from the moment of taking the drug to the beginning of the administration of ACC was 8 and 20 hours. High risk factors for the development of hepatotoxic effect in case of paracetamol poisoning are the time range from the moment of taking the drug to the beginning of the administration of ACC and the value of the paracetamol index.CONCLUSION Indications for the use of acetylcysteine in acute poisoning with paracetamol is a high risk of liver damage. Its criteria are high doses, increased concentrations of ALT and AST when patients are admitted to the hospital; if it is possible to determine the concentration of paracetamol in the blood, an increase in the value of the paracetamol index is more than 1. The use of a 21-hour protocol of intravenous administration of acetylcysteine is effective in case of paracetamol poisoning and its early use in the complex of treatment almost always prevents the development of acute liver failure.
Background. Paracetamol poisoning is common all over the world, including in Russia. In 20–25% of cases, a massive dose of the drug is observed: more than 30–40 g of paracetamol at a time.The aim of the study was to demonstrate the efficacy of using an increased doses of acetylcysteine in the treatment of a massive paracetamol admission.Results. Patient G., 22 years old, took 70 tablets (35 g) of paracetamol for suicide 3 hours before admission to the hospital. The blood level of paracetamol 4 hours after taking it was 694.94 µg/mL. Upon admission to the hospital, acetylcysteine administering was started according to a 12-hour scheme. Subsequently, the administration of acetylcysteine was continued according to a 20-hour regimen with an increased dosage at the 2nd stage. Laboratory parameters, including aspartate aminotransferase and alanine aminotransferase, remained within the reference values during hospital stay. Conclusion. The case report we have presented shows the efficacy and expediency of using an increased doses of acetylcysteine in case of massive admission of paracetamol, which contributes to the prevention of the development of severe complications and a favorable course and outcome of the disease.
