Head injuries are frequent reasons for consultations in the units. Most are minor trauma. Trauma in turn can cause serious and fatal injuries. Since the anatomical characteristics of the child make him more prone to suffer an intracranial injury. The present work leads to the development of a clinical case study on head trauma in a 3-year-old patient, children being one of the main affected. This case is presented at the Venus de Valdivia Type “C” Maternal and Child Health Center in the City of Santa Elena, La Libertad Parish. A theoretical framework is deepened where the information about head trauma reported by different authors is investigated. Head trauma is and will continue to be a frequent reason for pediatric emergency department visits. Therefore, the present clinical case is focused on the analysis of head trauma, based on the patient's medical history, and on the follow-up of health personnel for its improvement.Head injuries are frequent reasons for consultations in the units.

La mayoría son traumatismos leves. Los traumatismos a su vez pueden causar lesiones graves y letales. Ya que las características anatómicas del niño lo hacen más propenso de sufrir una lesión intracraneal. El presente trabajo da lugar a la elaboración de un estudio de caso clínico sobre traumatismo craneoencefálico en paciente de 3 años, siendo los niños uno de los principales afectados. Este caso se presenta en el Centro de Salud Materno Infantil Tipo “C” Venus de Valdivia en la Ciudad de Santa Elena, Parroquia La Libertad. Se profundiza un marco teórico donde se investiga la información acerca del traumatismo craneocenfalico que nos relatan diferentes autores. El trauma craneocenfalico es y seguirá siendo un motivo frecuente en las consultas en los servicios de urgencias en pacientes pediátricos. Por lo tanto, el presente caso clínico está enfocado en el análisis del traumatismo craneoencefálico, basado en la historia clínica del paciente, y en el seguimiento del personal de salud para su mejoría.
