TBI: The Battle for the Injured Brain with Professor David Menon

Professor David K. Menon joins us for an in-depth exploration of Traumatic Brain Injury (TBI). As the Founding Director of the Neurosciences Critical Care Unit at Addenbrooke’s Hospital, Professor Menon has been instrumental in shaping modern understanding of TBI physiology, monitoring, and management.In this episode, we break down intracranial pressure physiology in a way that translates directly to roadside decision-making, examining how brain swelling, cerebral perfusion, and autoregulation respond to early interventions. We focus on hypotension and hypoxia, the two most powerful drivers of secondary brain injury, and why the pre-hospital phase represents a critical window to influence outcomes long before CT imaging or neurosurgical care.We also explore the evidence for pre-hospital hypertonic therapy, discussing when it may be beneficial, where its limitations lie, and how it should (and should not) fit into contemporary practice. Practical considerations around airway management and ventilation are covered, including CO₂ targets, RSI decision-making, and strategies to avoid iatrogenic harm.Finally, we look ahead to emerging research and evolving concepts in TBI care, new physiological insights, changing targets, and innovative approaches aimed at reducing secondary brain injury, highlighting what pre-hospital clinicians should be thinking about now and in the years to come.Relevant resources and research networks:TBI-Reporter: https://tbi-reporter.uk/CENTER-TBI (Collaborative European NeuroTrauma Effectiveness Research in TBI): https://www.center-tbi.eu/This episode is essential listening for anyone involved in pre-hospital, retrieval, or critical care treating patients with traumatic brain injury.
