Intracranial pressure management and neurological outcome for patients with mild traumatic brain injury who required neurosurgical intervention: a Japanese database study

ABSTRACTPurpose: Among mild traumatic brain injuries (mTBI; a Glasgow Coma Scale score ≥13 on arrival), few result in severe neurological deficit, especially when they needed neurosurgical intervention. We investigated the association of intracranial pressure (ICP) control management with neurological outcome in patients with mTBI who needed neurosurgical intervention.Methods: From 1,092 records of the Japan Neurotrauma Data Bank during 2009–2011, we retrospectively identified 195 patients with neurosurgical intervention for mTBI. Using the Glasgow Outcome Scale, we grouped records into two: favorable and poor outcome. We analyzed neurological outcomes using a logistic regression analysis adjusted for ICP control managements.Results: Seventy patients had a poor outcome. Logistic regression analysis revealed that sedatives, hyperosmotic agents, and hyperventilation therapy were significantly associated with poor outcome (odds ratio [OR]: 2.36, 95% confidence interval [CI]: 1.31–4.26; OR: 2.81, 95% CI: 1.17...
