Area of Science:

  • Toxicology
  • Neurology
  • Emergency Medicine

Background:

  • Organophosphate (OP) ingestion is a significant cause of poisoning worldwide.
  • Accurate diagnosis is critical for timely and effective management of OP poisoning.
  • Neurological manifestations of OP poisoning can be complex and mimic other conditions.

Observation:

  • Two patients presented with unconsciousness following deliberate organophosphate ingestion.
  • Initial misdiagnosis as brainstem stroke led to consideration of treatment withdrawal.
  • Prompt and accurate diagnosis revealed organophosphate poisoning.

Findings:

  • Appropriate treatment, guided by correct diagnosis, led to full recovery in both patients.
  • Routine drug screens failed to detect organophosphates, highlighting diagnostic limitations.
  • The clinical presentation underscored the potential for OP toxicity to mimic neurological emergencies.

Implications:

  • Emphasizes the need for a broad differential diagnosis in unconscious patients, especially in cases of poisoning.
  • Highlights the inadequacy of standard toxicology screens for detecting organophosphates.
  • Underscores the critical importance of considering specific poisoning etiologies before withdrawing life support.
