Targeted temperature management in traumatic brain injury

Area of Science:

• Neuroscience
• Critical Care Medicine
• Neurosurgery

Background:

• Traumatic brain injury (TBI) is a leading global cause of death and disability.
• Current TBI treatments aim to improve patient outcomes, but novel neuroprotective strategies are needed.
• Targeted temperature management (TTM), encompassing therapeutic hypothermia (TH), is being investigated as a neuroprotective treatment for TBI.

Purpose of the Study:

• To elucidate the specific pathophysiological mechanisms through which TTM may be effective in TBI.
• To review existing clinical trials and recent randomized controlled trials (RCTs) evaluating TTM in TBI patients.
• To identify patient subgroups and TBI pathologies where TTM demonstrates the most significant benefits.

Main Methods:

• Review of historical and recent clinical trials, including large-scale randomized controlled trials (RCTs).
• Analysis of studies comparing therapeutic hypothermia (TH) with normothermia in TBI.
• Examination of preliminary reports from multicenter trials investigating TTM efficacy.

Main Results:

• Two recent RCTs demonstrated significant benefits of TTM in TBI patients with mass evacuated lesions.
• TTM appears particularly effective for ischemic-reperfusional pathophysiology, common in conditions like acute subdural hematoma.
• Preliminary data suggest TTM may effectively reduce elevated intracranial pressure in TBI patients.

Conclusions:

• Targeted temperature management (TTM) remains a central neuroprotective strategy for TBI.
• TTM is anticipated to alleviate ischemic-reperfusional injury and decrease intracranial pressure in TBI.
• Further results from ongoing clinical RCTs are crucial to solidify the role of TTM in TBI management.
