Anestesia para el paciente con traumatismo encéfalocraneano

Abstract

Traumatic brain injury (TBI) is the leading cause of death and disability for children and young adults. The Glasgow Coma Scale allows to classify TBI as mild, moderate and severe. Imaging studies show the heterogeneity of the diagnosis. Primary injury is caused by mechanical impact. Secondary injury contributes significantly to prognosis by exacerbating hypoperfusion and intracranial hypertension. Even in the absence of extracranial lesions, many patients with severe TBI present significant organ dysfunction, which transforms TBI into a multisystemic pathology. Most relevant systems compromised include cardiovascular, autonomic, respiratory and coagulation. The main aims of anesthetic management are: early decompression together with prevention, early detection, and management of determinants of secondary injury. To date, there are no techniques or drugs showing a significant impact on the outcome of TBI patients. On the other hand, maintaining good hemodynamic stability, adequate oxygenation and normocarbia all contribute to a better outcome.
