Antidepressant Poisoning Trends in Pediatric Intensive Care

Abstract

Purpose/BackgroundThis study aimed to compare the frequency, clinical findings, treatment practices, and outcomes of toxicity to old-generation (OG) and new-generation (NG) antidepressants in our pediatric intensive care unit (PICU) by year-to-year.Methods/ProceduresThe study included patients hospitalized for antidepressant poisoning during the 11-year period of January 2010 through December 2020. Antidepressants were classified as OG and NG. The groups were compared in terms of patient demographic characteristics, type of poisoning (accidental/suicidal), clinical findings, supportive and extracorporeal treatments received, and outcomes.Findings/ResultsThe study included 58 patients (NG, n = 30; OG, n = 28). The median age of the patients was 178 months (range, 13.6–215 months) and 47 patients (81%) were female. Patients admitted for only antidepressant poisoning constituted 13.3% of all poisoning cases (58/436). Of these, 22 cases (37.9%) were accidental and 36 (62.3%) were suicidal. The most common cause of poisoning was amitriptyline (24/28) in the OG group and sertraline (13/30) in the NG group. Neurological symptoms were significantly more common in the OG group (76.2% vs 23.8%), while gastrointestinal involvement was more common in the NG group (82% vs 18%; P = 0.001 and P = 0.026, respectively). Old-generation antidepressant poisoning was associated with more frequent intubation (4 vs 0 patients, P = 0.048) and longer length of PICU stay (median, 1 day [range, 1–8] vs 1 day [range, 1–4], P = 0.019). Rates of therapeutic plasma exchange and intravenous lipid emulsion therapy did not differ (P = 0.483 and P = 0.229, respectively).Implications/ConclusionsIn poisoned patients, proper evaluation and management of patients requiring PICU admission are vital for favorable patient outcomes.

“…Los antidepresivos más comunes en intoxicaciones son el grupo de los tricíclicos. En dosis terapéuticas (menos de 1mg/kg), estos fármacos inhiben la receptación presináptica de noradrenalina y serotonina (25). Sin embargo, presenta efectos secundarios como:taquicardia, temblor, ansiedad, agitación y náuseas (26).…”
