Neurotrauma and Critical Care – Interdisciplinary Approaches to Head Injury

Traumatic Brain Injury (TBI) remains a major global health challenge, contributing substantially to mortality, long-term disability, and socioeconomic burden, particularly in low- and middle-income countries. This chapter provides a comprehensive review of neurotrauma from pathophysiology to critical care, emphasizing the interdisciplinary framework required for optimal outcomes. The biological cascade of primary and secondary injury—including cerebral edema, ischemia, excitotoxicity, mitochondrial dysfunction, and neuroinflammation—is examined alongside clinical and radiological classification systems such as the Glasgow Coma Scale (GCS), Marshall Classification, and Rotterdam CT Score. Acute management strategies are detailed from pre-hospital stabilization using ATLS principles to emergency department protocols, neuroimaging, intracranial pressure (ICP) monitoring, and cerebral perfusion optimization. Neurosurgical interventions—including decompressive craniectomy, hematoma evacuation, and management of penetrating brain injuries—are analyzed with reference to clinical trial evidence and surgical indications. The chapter further explores neurocritical care principles encompassing ventilation, sedation, metabolic support, multimodal monitoring, and tiered ICP management. Emerging innovations such as AI-based triage systems, predictive analytics in ICU settings, robotic-assisted neurosurgery, image-guided precision interventions, stem-cell research, and biomarker-driven neuroprotective therapies are highlighted as transformative directions in modern neurotrauma care. The integration of neurosurgery, critical care, rehabilitation, and public health strategies underscores the necessity of collaborative, patient-centered management in improving survival and functional recovery after TBI.
