ABSTRACT

Traumatic Brain Injury (TBI) is an important Public Health issue in Chile and the world. It represents a frequent cause of consultation, constituting a significant cause of morbidity and mortality in the population under 45 years of age. Accidents are the main reason for TBI among the pediatric population, but child abuse is an important cause in children below 2 y.o. A proper evaluation is essential to develop timely and efficient treatment that avoids or decreases brain damage and eventual complications. For this purpose, it is essential that brain physiology and physiopathological changes triggered by TBI are clear and well known. Current concepts are presented in this paper, emphasizing brain hemodynamics, metabolism, and brain self-regulation.


El traumatismo encefalocraneano (TEC) es un importante problema de salud pública tanto en Chile como en el mundo. Representa un motivo de consulta frecuente constituyendo una de las mayores causas de morbi-mortalidad en la población menor de 45 años. Los accidentes son la principal causa de TEC en la población pediátrica, pero el maltrato infantil es una causa etiológica importante a considerar en los menores de 2 años. Realizar una correcta evaluación al paciente con TEC es fundamental para instaurar un tratamiento oportuno y eficiente con el fin de evitar y/o disminuir el daño cerebral y así prevenir eventuales complicaciones. Para ello es imprescindible el conocimiento de la fisiología cerebral y los cambios fisiopatológicos que se desencadenan posterior al TEC, conceptos que son revisados en este artículo con énfasis en la hemodinamia cerebral, metabolismo y autorregulación cerebral.
