Concussions affect the normal functioning of the autonomic nervous system and glucose metabolism, impair cerebral autoregulation to Paco₂, and produce abnormal variances in myogenic and vagal tone. Because anesthesia also has an impact on these same processes, it is vital to delineate the best practice in the perianesthesia period to minimize additional damage to the concussed brain. There are currently no practice guidelines surrounding perianesthesia management of patients with concussion to guide practice. ⋯ The impact of particular anesthetic agents on concussion injuries is unknown. Major advances in neuroimaging, biomarker identification, and technology have occurred. However, further research is needed to identify evidence-based interventions for managing patients after concussion requiring anesthesia.
