Emamectin Poisoning in Thailand: Clinical Characteristics and Outcomes.

Emamectin benzoate (Emamectin) is a broad-spectrum insecticide. Current data regarding emamectin poisoning in humans are very limited. We performed a 10-year retrospective cross-sectional study (2011-2020) using data from the Ramathibodi Poison Center database to examine the clinical characteristics and outcomes in patients exposed to emamectin. Eighty-eight patients were included. Most of the patients were male (72.7%) and exposure was frequently oral (86.4%) and intentional (67.0%).Their mean age was 42.8 years. The clinical presentations included gastrointestinal tract symptoms (62.5%), neurological symptoms (27.3%) including seizures, respiratory symptoms (6.8%), and local effects (12.5%). At presentation, the majority of patients exhibited normal consciousness and vital signs. Eleven patients showed no obvious clinical effects. Initially, 15 patients had metabolic acidosis and 11 had hypokalemia. Overall, 46 and 52 patients were administered gastric lavage and activated charcoal, respectively. Most patients (78.4%) were hospitalized, with a median hospital stay of 40 h, and generally received supportive treatment. Eight patients were intubated for ventilator support and one received inotropic drugs. Most patients (90.9%) showed no or minor outcomes; however, two patients died. The presence of Glasgow Coma Scale (GCS) <15 differed significantly (
