Chloral hydrate, a common sleep aid, poses significant acute toxicity risks. This case highlights the dangers of overdose and supports its removal from the market due to safety concerns.

Area of Science:

  • Toxicology
  • Pharmacology
  • Emergency Medicine

Background:

  • Chloral hydrate is a widely prescribed sedative-hypnotic agent.
  • Cumulative reports indicate significant toxicity associated with its use.
  • Concerns exist regarding the safety profile of chloral hydrate as a sleep aid.

Observation:

  • A 29-year-old male presented with severe toxicity after ingesting 70g of chloral hydrate.
  • The patient experienced hypotension, hypothermia, and respiratory insufficiency.
  • Ventricular arrhythmias occurred during low-dose catecholamine infusion.

Findings:

  • Combined hemoperfusion and hemodialysis effectively reduced serum trichlorethanol levels.
  • The patient's hemodynamics improved, with increased blood pressure and heart rate.

  • Neurological deficits were absent upon recovery of consciousness.

    • Implications:

    • This case underscores the high acute toxicity potential of chloral hydrate.
    • The findings support the re-evaluation of chloral hydrate's place in clinical practice.
    • Consideration should be given to removing chloral hydrate from the market due to its toxicity profile.
