The Association Between Brain Temperature and Neurological Outcome in Out-of-Hospital Cardiac Arrest Patients Who Received Targeted Temperature Management at 33 °C—Graphical Abstract

A research team from Chonnam National University Medical School and Chonnam National University Hospital, including Seok Jin Ryu and colleagues, has published a study titled “The Association Between Brain Temperature and Neurological Outcome in Out-of-Hospital Cardiac Arrest Patients Who Received Targeted Temperature Management at 33 °C” in Reviews in Cardiovascular Medicine (RCM), Volume 26, Issue 11.

Background:

  • Core Temperature (CT) primarily reflects systemic physiological states.
  • Brain Temperature (BT) directly reflects cerebral metabolic activity and regional blood flow.
  • The relationship between BT and neurological outcomes in OHCA patients under Targeted Temperature Management (TTM) remains unclear.

Patients & Methods:

  • Population: 149 adult OHCA patients treated with TTM at 33 °C.
  • Measurements: BT (zero-heat-flux sensor) and CT (esophageal probe) were measured at two phases:

Initiation of TTM (BTINI / CTINI)
Maintenance phase of TTM (BTMAIN / CTMAIN)

  • Primary Outcome: Poor neurological outcome (CPC 3-5) at 6 months after ROSC.

Results:

  • BTINI and BTMAIN were significantly lower in the poor outcome group.
  • Lower BTINI and BTMAIN were independently associated with poor neurological outcomes.
  • BT demonstrated better prognostic performance than CT (AUC: BTMAIN 0.773 vs. CTMAIN 0.615).

Conclusion:

  • Lower Brain Temperature observed during TTM at 33 °C is associated with poor neurological outcomes.
  • BT may serve as a more precise clinical marker of severe hypoxic brain injury following cardiac arrest.
