First Breath Matters: Out-of-Hospital Mechanical Ventilation in Patients with Traumatic Brain Injury.

Area of Science:

• Neurocritical care
• Respiratory medicine
• Emergency medicine

Background:

• Invasive mechanical ventilation (MV) is vital for traumatic brain injury (TBI) patients to maintain gas exchange and prevent secondary brain injury.
• MV management in TBI requires careful consideration of cerebral autoregulation, intracranial pressure (ICP), cerebral perfusion pressure (CPP), and systemic hemodynamics.
• Protective ventilation strategies, while beneficial for many critically ill patients, may negatively impact brain physiology in TBI cases.

Purpose of the Study:

• To review current evidence on mechanical ventilation in patients with TBI.
• To emphasize the critical role and current data limitations of prehospital MV in TBI management.

Main Methods:

• Literature review of existing studies on mechanical ventilation in TBI patients.
• Focus on prehospital data and challenges.

Main Results:

• Optimal MV strategies for TBI patients, particularly in prehospital settings, remain incompletely defined.
• Existing data on out-of-hospital MV for TBI is scarce.
• Potential adverse effects of standard protective ventilation on cerebral hemodynamics in TBI are a concern.

Conclusions:

• Further research is needed to define optimal MV strategies for TBI patients, especially in the prehospital phase.
• Balancing gas exchange needs with the risks of MV-induced hemodynamic compromise is essential in TBI care.
• Prehospital MV plays a crucial role in mitigating secondary brain injury following TBI.
