Household and Environmental Toxicoses – BCSE Study Guide
Overview and Clinical Importance
Household and environmental toxicoses represent some of the most common emergency presentations in small animal practice. Understanding the mechanisms of action, clinical presentations, and appropriate treatments for these toxins is essential for entry-level veterinarians and heavily tested on the BCSE examination.
Ethylene Glycol Toxicity
Ethylene glycol (EG) is the primary toxic component in automotive antifreeze, representing one of the most life-threatening toxicoses in companion animals. Its sweet taste makes it attractive to pets, and even small amounts can be fatal.
Sources and Toxic Doses
Common sources include: automotive antifreeze (95% EG concentration), brake fluid, windshield deicing agents, heat exchange fluids, and some paints/solvents.
