RESUMO
Among all types of trauma in children, traumatic brain injury has the greatest potential for the development of devastating consequences, with nearly three million affected each year in the world. A controlled, nonrandomized experimental study was carried out in pediatric patients with severe traumatic brain injury, whose objective was to evaluate the use of continuous multimodal neuromonitoring (MMN) of intracranial parameters as a guide in the treatment of children of different age-groups. The patients were divided into two groups according to the treatment received; clinical and imaging monitoring was performed in both. Group I included those whose treatment was guided by MMN of intracranial parameters such as intracranial pressure, cerebral perfusion pressure, and intracranial compliance, and group II included those who had only clinical and imaging monitoring. Eighty patients were studied, 41 in group I and 39 in group II. There were no significant differences between the groups with respect to the sociodemographic variables and the results; as a consequence, both forms of treatment were outlined, for patients with MMN and for those who only have clinical and imaging monitoring. It is concluded that both treatment schemes can be used depending on technological availability, although the scheme with MMN is optimal.
RESUMO
Introduction: The prehospital phase of the management of pediatric severe traumatic brain injury may have a direct influence on the results. Objective: To evaluate the influence of prehospital variables on intracranial pressure and the results in pediatric patients with severe TBI. Method: A descriptive study of 41 pediatric patients who were admitted to the medical emergency department and later admitted to the pediatric intensive care unit due to severe head trauma was carried out between January 2003 and December 2018. Results: children aged 5-17 years predominate, and the highest number of cases were received between 0-3h at the neurotrauma center. Of the 41 cases, 27 arrived with a non-expedited airway and hypoxia was verified upon arrival by pulse oximetry. A correlation was observed between arterial hypotension on admission and elevated intracranial pressure in 9 of 15 children (60%) and in the deceased (40%). Discussion: Clinical conditions, oxygenation, arterial hypotension, and treatment in the prehospital phase may influence the state of intracranial pressure and other intracranial variables in pediatric patients with severe head injury.
Introducción: La fase prehospitalaria del manejo del traumatismo craneoencefálico grave pediátrico puede tener una influencia directa en los resultados. Objetivo: Evaluar la influencia de variables prehospitalarias sobre la presión intracraneal y los resultados en pacientes pediátricos con TCE grave. Metodología: Se realizó un estudio descriptivo de 41 pacientes pediátricos que ingresaron al servicio de urgencias médicas y posteriormente ingresaron a la unidad de cuidados intensivos pediátricos por traumatismo craneoencefálico severo entre enero de 2003 y diciembre de 2018. Resultados: predominan los niños de 5 a 17 años, y el mayor número de casos se recibieron entre las 0-3h en el centro de neurotrauma. De los 41 casos, 27 llegaron con vía aérea no acelerada y se verificó hipoxia al llegar mediante oximetría de pulso. Se observó correlación entre hipotensión arterial al ingreso y presión intracraneal elevada en 9 de 15 niños (60%) y en los fallecidos (40%). Discusión: Las condiciones clínicas, la oxigenación, la hipotensión arterial y el tratamiento en la fase prehospitalaria pueden influir en el estado de la presión intracraneal y otras variables intracraneales en pacientes pediátricos con traumatismo craneoencefálico grave.
RESUMO
Introducción: El traumatismo craneoencefálico es responsable de más de 500 000 visitas a departamentos de urgencias, 95 000 hospitalizaciones y 7 000 muertes en la población infantil. La monitorización clínica se apoya en técnicas imagenológicas, entre otras. Objetivo: Relacionar los hallazgos tomográficos encontrados, a través de la clasificación de Marshall al ingreso y diámetro de la vaina del nervio óptico y su asociación con la presión intracraneal y con los resultados en el paciente pediátrico con traumatismo craneoencefálico grave. Métodos: Estudio descriptivo prospectivo con todos los pacientes pediátricos aquejados de traumatismo craneoencefálico grave entre enero de 2003 y diciembre de 2017. Resultados: De los 41 casos, se encontró relación entre los niveles de presión intracraneal y el grado de luxación de la línea media >10 mm en 10 enfermos (62,5 %) y con el diámetro de la vaina del nervio óptico (>5,5 mm) por tomografía de cráneo en 12 (75,0 %), igualmente existió relación entre esas dos variables con los resultados a los 6 meses de evolución. Conclusiones: La utilización de la tomografía de cráneo simple como herramienta para la determinación de variables utilizadas en el monitoreo no invasivo de la presión intracraneal como son la clasificación tomográfica de Marshall, la luxación de la línea media y la medición del diámetro de la vaina del nervio óptico, permite identificar incrementos de la presión intracraneal. Esto pudiera utilizarse para el tratamiento intensivo de los pacientes pediátricos con traumatismo cráneo encefálico grave, sin necesidad de la utilización de monitoreo invasivo en ellos.
Introduction: Traumatic brain injury is responsible for more than 500,000 visits to the emergency services, 95,000 hospitalizations and 7,000 deaths in children. Clinical monitoring is based on imaging techniques, among others. Objective: To relate the tomographic findings found, through Marshall's classification at the entrance and diameter of the optic nerve sheath and its association with intracranial pressure and with the results in the pediatric patient with severe head trauma. Methods: Prospective descriptive study with all pediatric patients suffering from severe head trauma between January 2003 and December 2017. Results: Of the 41 cases, a relationship was found between the levels of intracranial pressure and the degree of dislocation of the midline >10 mm in 10 patients (62.5%) and with the diameter of the optic nerve sheath (>5.5 mm) by skull tomography in 12 (75.0%); there was also a relationship between these two variables with the results at 6 months of evolution. Conclusions: The use of simple tomography of the skull as a tool for the determination of variables used in the non-invasive monitoring of intracranial pressure such as Marshall tomographic classification, midline dislocation and measurement of the diameter of the optic nerve sheath, allows to identify increases in intracranial pressure. This could be used for the intensive treatment of pediatric patients with severe head trauma, without the need for invasive monitoring in them.
RESUMO
Resumen: Introducción: el uso de presión positiva al final de la espiración mejora la oxigenación y recluta alvéolos, aunque también provoca alteraciones hemodinámicas e incrementa la presión intracraneal. Material y métodos: se realizó un estudio preexperimental de un solo grupo en pacientes pediátricos aquejados de traumatismo craneoencefálico grave, con hipoxemia asociada, tratados con diferentes niveles de presión positiva al final de la espiración, a los que se les monitorizó la presión intracraneal y la presión de perfusión cerebral para evaluar el efecto de esta maniobra ventilatoria en las variables intracraneales. Resultados: predominaron las edades entre cinco y 17 años, 14 (73.68%) y la escala de coma de Glasgow al ingreso de ocho a nueve puntos (47.36%). La presión intracraneal aumenta cuando la presión positiva al final de la espiración supera los 12 cmH2O. La escala de coma de Glasgow al ingreso de ocho puntos se asoció con secuelas ligeras o ausencia de secuelas (47.36%), todos los niños con tres puntos fallecieron. Conclusiones: el empleo de presión positiva al final de la espiración en el traumatismo craneoencefálico grave requiere de monitorización continua de la presión intracraneal. Corregir la hipertensión intracraneal y la inestabilidad hemodinámica son condiciones necesarias previas al tratamiento.
Abstract: Introduction: the use of positive end expiratory pressure improves oxygenation and recruits pulmonary alveoli, however at the same time it leads to hemodynamic changes and increase intracranial pressure. Material and methods: a prospective descriptive study was done with pediatric patients afflicted with severe traumatic brain injury associated with hypoxemia and treated with different levels of positive end expiratory pressure, to whom the intracranial pressure and cerebral perfusion pressure were monitored so as to evaluate the effect of this ventilation maneuver over the intracranial variables. Results: patients with age between 5-17 years old as well as male sex, 14 (73.68%) were predominant. 9 (47.36%) showed Glasgow coma scale of 8 points on admission. Intracranial pressure starts to rise when the positive end expiratory pressure exceeds 12 cmH2O. Glasgow coma scale with 8 points was associated with mild disability or no disability (47.36%). All the patients that scored 3 points died. Conclusions: the use of positive end expiratory pressure to correct hypoxemia was an applicable therapeutic alternative as long as continuous intracranial pressure monitoring was available in a systematic and personalized way. The correction of intracranial hypertension and hemodynamic instability were a necessary condition before using the ventilatory maneuver in these patients.
Resumo: Introdução: o uso de pressão positiva no final da expiração melhora a oxigenação e recruta alvéolos, embora também cause alterações hemodinâmicas e aumente a pressão intracraniana. Material e métodos: realizou-se um estudo pré-experimental de um único grupo em pacientes pediátricos vítimas de traumatismo cranioencefálico grave, com hipoxemia associada, tratados com diferentes níveis de pressão positiva ao final da expiração, nos quais foram monitoradas a pressão intracraniana e a pressão de perfusão cerebral, para avaliar o efeito desta manobra ventilatória em variáveis intracranianas. Resultados: predominou a faixa etária entre 5-17 anos, 14 (73.68%) e a escala de coma de Glasgow na admissão de 8 pontos, 9 (47.36%). A pressão intracraniana aumenta quando a pressão positiva no final da expiração excede 12 cmH2O. A escala de coma de Glasgow na admissão de 8 pontos foi associada a sequelas leves ou sem sequelas (47.36%), todas as crianças com 3 pontos morreram. Conclusões: a utilização de pressão positiva no final da expiração no TCE grave requer monitorização contínua da pressão intracraniana. A correção da hipertensão intracraniana e da instabilidade hemodinâmica são condições necessárias prévias ao tratamento.
RESUMO
INTRODUCTION: Severe craniocerebral trauma is the main cause of morbidity and mortality in children worldwide. Neuromonitoring of these patients in Cuba is not routine in paediatric intensive cares units, and there is no standardised protocol for its use in these units. MATERIALS AND METHODS: A correlational longitudinal prospective study was conducted on all patients admitted to the paediatric intensive care unit with the diagnosis of severe craniocerebral trauma in the period between January 2003 and December 2014. Continuous neuromonitoring of intracranial pressure and cerebral perfusion pressure was carried out. RESULTS: The results showed that there was a correlation between the initial images of CT scan and the grade of shift of the half line structures. There was a direct relationship between intracranial pressure and the outcomes. The use of early decompressive craniectomy facilitated the rapid control of the intracranial hypertension. CONCLUSIONS: Continuous neuromonitoring contributes to adopt a therapeutic posture in the handling of the paediatric patients with severe head trauma.

Introduction: Traumatic brain injury is defined as brain damage caused by an external force, and can produce an altered state of consciousness, resulting in deterioration of the functioning of cognitive and physical abilities. The Glasgow Coma Scale allows us to classify the degree of traumatic brain injury. Treatment should be initiated with appropriate resuscitation, according to the protocol advanced trauma life support. Method: PudMed, Scielo, Cuiden, Ciberindex, Cochrane VHL and other bases were used; standard sequence for finding information in electronic databases was established. The search was limited to 10 years from the current date, in English or Spanish language. 10 systematic and 14 narrative reviews were useful for the development of this guide. Results: The initial management in all patients with head trauma must be supported by the principles of Advanced Trauma Life Support (ATLS). If an episode of hypoxia is generated increase mortality by 50%; low blood pressure episode increases it by 100%. All alterations of consciousness are emergencies until vital functions are stabilized. Conclusion: Clinical Practice Guide allows nurses to standardize and give better service in the care and management of patients with severe head trauma. It serves as a basis for decision-making.
