简要总结
Scorpion stings are a common medical emergency in Mexico, particularly in the state of Jalisco. While antivenom is the standard treatment for scorpion envenomation, there is variability in how it is used, including differences in dosing strategies. In addition, many patients use home remedies before seeking medical care, which may delay treatment and influence the severity of symptoms.
This study is an observational, retrospective analysis of patients treated for scorpion envenomation in the emergency department of a public hospital in Jalisco, Mexico, between 2021 and 2023. Using information from medical records, the study examines the relationship between the use of home remedies, the time to receive medical care, clinical severity at presentation, and the antivenom dosing strategies used, including traditional and reduced-dose approaches.
The goal of this study is to better understand factors associated with clinical severity and antivenom use in real-world emergency care. The results may help inform future clinical decision-making, promote rational use of antivenom, and improve timely access to appropriate medical treatment for patients with scorpion envenomation.

研究组 & 干预措施
Traditional dose
This group includes patients diagnosed with scorpion envenomation who were managed according to the traditional antivenom dosing strategy recommended by the Mexican national Clinical Practice Guidelines. These guidelines advise administering antivenom (faboterápico) to all patients with scorpion envenomation, independent of whether systemic symptoms are present, with dosing adjusted based on patient age and clinical severity.
Under this strategy, patients typically received one or more intravenous vials of antivenom as an initial dose, with additional doses administered at predefined intervals if symptoms persisted, in accordance with guideline-based algorithms. All treatments were provided as part of routine emergency care, and no interventions were assigned for research purposes. This group reflects standard-of-care antivenom use in Mexico during the study period.
Reduced dose
This group includes patients diagnosed with scorpion envenomation who were managed using a reduced-dose antivenom strategy during routine emergency care. In this approach, antivenom (faboterápico) was administered primarily to patients with systemic manifestations of envenomation. The initial dose generally consisted of a single intravenous vial, with additional vials administered only if clinical symptoms persisted or progressed after reassessment.
Patients who did not receive antivenom because they presented without systemic symptoms were also included in this group. This management strategy differs from the Mexican national Clinical Practice Guidelines, which recommend antivenom administration to all patients with scorpion envenomation, regardless of the presence or absence of systemic symptoms. All treatment decisions were made by the treating physicians as part of standard clinical care, without protocol-mandated interventions.
