Summary
Accidental hypothermia in an elderly patient can be life-threatening. Prompt rewarming and fluid replacement therapy led to a full recovery, demonstrating the importance of early intervention for hypothermia survival.
Area of Science:
- Emergency Medicine
- Cardiology
- Geriatrics
Background:
- Accidental hypothermia presents a significant clinical challenge, particularly in elderly individuals.
- Severe hypothermia can lead to altered consciousness, shock, and characteristic ECG changes like the J wave.
Observation:
- An 87-year-old female presented with severe accidental hypothermia, altered consciousness (JSC III-200), decorticate rigidity, and shock.
- Initial body temperature was unrecordable, and electrocardiogram (ECG) showed a prominent J wave.
Findings:
- The patient received external rewarming and intravenous warm fluid resuscitation.
- Consciousness improved to JSC II-20 within 2.5 hours and JCSI-1 by 7.5 hours.
- Body temperature normalized to 34.5°C after 9.5 hours, with resolution of the ECG J wave.
Implications:
- Early diagnosis and appropriate therapeutic interventions, including rewarming and fluid replacement, are crucial for improving outcomes in accidental hypothermia.
- This case highlights the successful management of severe hypothermia in an elderly patient, emphasizing the efficacy of prompt medical care.
