Protective hypothermia: An old therapy with a new prospective

Area of Science:

• Cardiology
• Neurology
• Critical Care Medicine

Background:

• Therapeutic hypothermia, or protective hypothermia, has historical roots and renewed interest following landmark publications.
• Neurological outcome is critical for survival and quality of life in post-cardiac arrest patients.
• Mild induced hypothermia is a recommended intervention to enhance neurological status.

Observation:

• A young female patient experienced perioperative cardiac arrest with immediate resuscitation.
• Her post-resuscitation Glasgow Coma Score (GCS) was five.
• Therapeutic hypothermia was induced, requiring sedation and muscle relaxants.

Findings:

• Following 24 hours of hypothermia and a slow rewarming process, the patient's GCS improved to 14 by day four.
• Extubation occurred on day 6, with the patient exhibiting mild cognitive disorder but remaining functionally independent.
• The patient was discharged home on day 11.

Implications:

• Mild induced therapeutic hypothermia demonstrates efficacy in improving neurological status for post-cardiac arrest patients.
• Awareness and application of this approach are crucial for acute care physicians, nurses, and emergency medical services.
• Potential adverse effects include an increased risk of infection, arrhythmia, and electrolyte imbalances, necessitating careful monitoring.
