Summary
Post-resuscitation hyperthermia, or elevated body temperature after resuscitation, is an early indicator of brain damage. Patients developing brain death showed earlier and higher fever compared to those in prolonged coma.
Area of Science:
- Neurology
- Critical Care Medicine
- Physiology
Background:
- Post-resuscitation hyperthermia is a common complication following cardiac arrest.
- The clinical significance of hyperthermia in the early post-resuscitation period requires further clarification.
Purpose of the Study:
- To investigate the clinical characteristics and prognostic value of post-resuscitation hyperthermia.
- To determine the association between hyperthermia and neurological outcomes after cardiac arrest.
Main Methods:
- Retrospective chart review of 18 patients who achieved return of spontaneous circulation after cardiac arrest.
- Analysis of body temperature within the first 48 hours post-resuscitation.
- Exclusion of patients with trauma, burns, poisoning, or cerebrovascular accidents.
Main Results:
- Most patients exhibited a rapid increase in body temperature after resuscitation.
- Hyperthermia onset was significantly earlier (median 6.2 hours) and peak temperature higher (median 39.8°C) in patients who later developed brain death compared to those in prolonged coma (median 12.7 hours and 38.3°C).
- Temperatures exceeding 39°C were associated with subsequent brain death; patients with full recovery did not experience hyperthermia.
Conclusions:
- Post-resuscitation hyperthermia serves as an early predictor of neurological damage.
- The timing and magnitude of temperature elevation are critical indicators of patient prognosis after cardiac arrest.
