Review Meta Analysis
Beta Blockers for Acute Traumatic Brain Injury: A Systematic Review and Meta-analysis.
Traumatic brain injury (TBI) is associated with a systemic hyperadrenergic state. Through activation of beta adrenoreceptors, catecholamines may induce hypermetabolism and increase both cardiac and cerebral oxygen demands. We conducted a systematic review to appraise the available evidence examining the safety and efficacy of beta blockers in patients with acute TBI. ⋯ The current body of evidence is suggestive of a benefit of beta blockers following TBI. However, methodologically sound randomized controlled trials are indicated to confirm the efficacy of beta blockers in patients with TBI.
