Pediatric traumatic brain injury: beyond the guidelines.

In 2003, a multidisciplinary group of physicians formulated the first guidelines for the management of severe traumatic brain injury in infants and children. Initial treatment of these patients is focused on stabilization to prevent the occurrence of secondary insults such as hypotension and hypoxemia. However, this article focuses on the established and emerging therapies used in the intensive care unit management of intracranial hypertension--which represents the key target for contemporary therapy of this condition. A critical pathway for the treatment of this condition was established within the guidelines, and this pathway is appropriately focused on limiting intracranial hypertension and optimizing cerebral perfusion during the intensive care unit phase. This includes first- and second-tier therapies. This article contains a brief synopsis of this critical pathway and discusses important new developments for the management of this condition. Key new developments include a better understanding of the optimal cerebral perfusion pressure target for intracranial pressure-directed therapy, with emerging evidence supporting the use of two therapeutic modalities, mild-moderate hypothermia and decompressive craniectomy.
