No Events

Overdoses and poisonings are sometimes familiar and sometimes frightening, and are a small but important part of the practice of emergency medicine. Toxicology will focus on the interesting world of poisons, their nature, effects and antidotes.

Learning Objectives

At the end of this program, the learner can expect to:

  • For apparently benign intoxication, not underestimate or miss the serious cases; and, not over treat the truly benign cases
  • Use a systematic approach to a patient presenting with coma of unknown cause
  • Look for physical signs that define and identify the toxidrome
  • Use a systematic approach to treat an agitated/delirious patient to identify those with a toxic etiology
  • Enhance elimination of toxins using appropriate methods
  • Decontaminate the patient appropriately
  • For a patient presenting with metabolic acidosis, come up with differential diagnosis and investigate to make a definite diagnosis
  • Use antidotes appropriately
  • Deal with the patient who refuses treatment while respecting their rights
  • Use laboratory and other tests efficiently
  • Look for and recognize difficult/serious intoxication that commonly kill, and manage them aggressively
