Insights
Chloral hydrate (CH) poisoning, though rare, can cause severe neurotoxicity and cardiotoxicity, even cardiac arrest. Prompt recognition and treatment with beta-blockers can lead to a full recovery.
Area of Science:
- Toxicology
- Cardiology
- Emergency Medicine
Background:
- Chloral hydrate (CH) is a sedative used in outpatient procedures, despite potential toxicity.
- CH poisoning is infrequently encountered in emergency settings.
Observation:
- A case of CH poisoning presented with neurotoxicity, progressing to cardiotoxicity and cardiac arrest.
- The patient experienced severe cardiac arrhythmias unresponsive to standard treatments.
Findings:
- Successful resuscitation and recovery were achieved with a high index of suspicion and appropriate management.
- Beta-blockers were identified as a key intervention for CH-induced refractory arrhythmias.
Implications:
- Highlights the importance of considering CH toxicity in patients with unexplained neurological and cardiac events.
- Suggests beta-blockers as a targeted therapy for managing chloral hydrate-induced cardiac arrhythmias.
- Emphasizes the need for careful consideration of sedative choices in outpatient procedures.
Abstract:
Chloral hydrate (CH) poisoning is not commonly seen in the emergency department. CH is a commonly prescribed sedative agent for various day care procedures despite its toxic profile even when other safe sedative medications are available. We report a case of CH poisoning that manifested with neurotoxicity followed by cardiotoxicity leading to cardiac arrest. With a high index of suspicion and proper management, our patient was discharged with normal neurological outcome. In this case report, we discuss CH poisoning and toxicity with highlights on specific intervention including β-blockers. CH induced arrhythmias have been reported to be refractory to the standard antiarrhythmic medications and respond well to β-blockers.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
