[The influence of the dose, time since ingestion and concentration of the xenobiotic on the clinical state and severity of liver damage with patients intoxicated with paracetamol].
The aim of this study was to determine relations between the clinical state and the severity of liver damage comparing to the amount of ingested paracetamol, time since ingestion and serum concentration of paracetamol with patients after acute intoxication with this drug. A retrospective analysis of medical records of 95 patients hospitalized in the Toxicology Department in Kraków or treated in the Toxicological Admission Room in 2002-2004 years because of acute paracetamol intoxication was performed. The general clinical state connected with intoxication and the severity of liver damage were determined using the Poisoning Severity Score (PSS). The level of consciousness was determined with the Glasgow Coma Scale and Matthew's scale. The serum concentration of paracetamol during admission to the hospital, levels of biochemical markers of liver damage (AST, ALT), bilirubin and INR index were also performed. We found a statistically significant positive correlation between the ingested dose of paracetamol comparing to the gravity of poisoning, the severity of liver damage, levels of aminotransferases and bilirubin. A positive correlation between time since ingestion of paracetamol to hospitalization and the gravity of poisoning according to PSS scale was also statistically significant. A paracetamol concentration measured during admission to the hospital had no influence on neither the clinical state of patient nor the severity of liver damage. We conclude that the therapeutical approach should consider possibly shortening of the time since drug ingestion to hospitalization and institution of specific treatment (N-acetylcysteine) as well as minimalization of the paracetamol dose, which could be absorbed, by different methods of elimination from the GI tract (eg., gastric lavage, activated charcoal laxatives).
