Epidemiological Pattern of Extracorporeal Methods in Acute Poisoning: A Five Year Study

Background: The use of hemodialysis is a prevalent extracorporeal technique for managing the poisoning of certain patients. Objectives: In this study, we examined the frequency of extracorporeal methods and the prognosis of using these methods in various poisonings. Methods: This retrospective study was conducted at Loghman Hakim hospital in Tehran between 2016 and 2020. The study investigated all patients who were hospitalized and underwent hemodialysis at the poisoning center. The study analyzed demographic data, clinical information, and certain laboratory findings from a sample size of 980 cases. The data obtained from the study were analyzed using SPSS 22. Results: 793 (80/9%) males and 187 (19.1%) females were investigated. The mean age of the subjects was 36.5±14 years. Methanol consumption was the highest cause of poisoning (858 cases, 87.6%). Hemodialysis was the most widely used extracorporeal method (971 cases, 99.1%). The median number of hemodialysis was 1 times and the maximum was 18. The mortality rate was 13.3%. Metabolic acidosis was observed in 823 cases (84%). Acute kidney injury (AKI) was present in 536 cases (54.7%). Conclusions: Although there have been some published studies and conferences on extracorporeal methods for treating poisonings, the lack of cases treated with these methods has resulted in weak evidence. To address this issue and provide more widely applicable data, studies like this can help to improve the treatment of poisoned patients.
