Ambulance transport for overdose patients leads to faster gastrointestinal decontamination, specifically gastric lavage, in the emergency department compared to other transport methods. This rapid intervention is crucial for altering drug absorption.

Area of Science:

  • Emergency Medicine
  • Clinical Toxicology
  • Pharmacokinetics

Background:

  • Gastrointestinal decontamination efficacy decreases with time post-ingestion.
  • Timely decontamination is critical for managing overdose patients.
  • Mode of transport may influence the speed of emergency department interventions.

Purpose of the Study:

  • To compare the time to gastrointestinal decontamination for overdose patients based on transport method.
  • To determine if ambulance transport impacts the timeliness of gastric lavage or activated charcoal administration.

Main Methods:

  • Retrospective chart review of oral overdose cases treated with gastrointestinal decontamination.
  • Analysis of data from December 1995 to May 1996 in an academic university emergency department.

  • Comparison of time intervals from emergency department arrival to decontamination between ambulance and other transport groups.

    • Main Results:

    • Patients transported by ambulance (67% of cases) had a shorter median interval to gastrointestinal decontamination (55 minutes) than those arriving by other means (73 minutes).
    • This time difference was statistically significant (P =.03) and primarily driven by faster gastric lavage administration.
    • Admission rates were comparable between transport groups.

    Conclusions:

    • Ambulance transport is associated with a reduced time to gastrointestinal decontamination for overdose patients.
    • Gastric lavage, in particular, is administered more rapidly in patients arriving via ambulance.
    • Optimizing transport logistics can improve the timeliness of critical overdose interventions.
