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

This randomized clinical trial aimed to evaluate different fluid therapy protocols associated with inhalational or total intravenous anesthesia in the cardiorespiratory stability of bitches with sepsis subjected to a surgical procedure to control the infectious focus. Thirty-two bitches diagnosed with pyometra and sepsis and treated at the University Veterinary Hospital between 2018 and 2019 were recruited. After admission, diagnosis, clinical, and laboratory evaluation, patients were randomly distributed into the following groups: propofol 5 (P[5]: preoperative restrictive fluid therapy-5mL/kg/h and intravenous general anesthesia); propofol 10 (P[10]: preoperative liberal fluid therapy-10mL/kg/h and intravenous general anesthesia); and isoflurane 5 (I[5]: preoperative restrictive fluid therapy-5mL/kg/h and inhalational general anesthesia). Lactate on admission (LAC1) and release (LAC2), heart rate (HR), respiratory rate (RR), systolic blood pressure (SBP), rectal temperature (RT), oxygen saturation (SpO2), and carbon dioxide extraction rate (EtCO2) were analyzed at PRE, T10, T20, T30, T40, T50, TEXT, and TDIS. Clearance of 20% of lactate occurred in 18 dogs, with the P[10] group displaying the best performance. There was no statistical difference in vasopressor requirements among the groups. Liberal fluid therapy showed greater cardiovascular stability than restrictive therapy in the perioperative period. Regarding general anesthesia, isoflurane showed greater cardiorespiratory stability than propofol during anesthetic maintenance. In conclusion, although the three proposed protocols are safe and there is no difference in their superiority, some observed changes may be relevant and considered when it is possible to individualize the therapy for the patient.

Este ensaio clínico randomizado teve a proposição de avaliar diferentes protocolos de fluidoterapia associados a anestesia inalatória ou total intravenosa, na estabilidade hemodinâmica de cadelas com sepse, submetidas a procedimento cirúrgico, para controle do foco infeccioso. Foram incluídas trinta e duas cadelas, com diagnóstico de piometra e sepse, atendidas em hospital veterinário universitário, no período de 2018 a 2019. Após admissão, diagnóstico, avaliação clínica e laboratoriais, os pacientes foram distribuídos de maneira aleatória nos grupos Propofol 5 (P[5]: fluidoterapia restritiva pré-operatória - 5mL/kg/h e anestesia geral intravenosa), Propofol 10 (P[10]: fluidoterapia liberal pré-operatória - 10mL/kg/h e anestesia geral intravenosa) e Isoflurano 5 (I[5]: fluidoterapia restritiva pré-operatória - 5mL/kg/h e anestesia geral inalatória). Foram analisados lactato na admissão (LAC1) e liberação (LAC2), frequências cardíacas (HR) e respiratória (RR), pressão arterial sistólica (SBP), temperatura retal (RT), saturação de oxigênio (SpO2) e taxa de extração de dióxido de carbono (EtCO2) nos seguintes momentos: PRE, T10, T20, T30, T40, T50, TEXT e TDIS. A depuração de 20% do lactato ocorreu em 18 cães, tendo o grupo P[10] o melhor desempenho. Não houve diferença estatística no requerimento de vasopressores entre os grupos. A fluidoterapia liberal apresentou maior estabilidade cardiovascular quando comparado com a restritiva no período perioperatório. Com relação a anestesia geral, o isoflurano apresentou maior estabilidade cardiorrespiratória que o propofol na manutenção anestésica. Nós concluímos que apesar de os três protocolos propostos serem seguros e sem diferença em superioridade entre eles, algumas alterações observadas podem ser relevantes e ponderadas quando for possível a individualização da terapêutica no paciente.

RESUMO

Introducción: El dengue es la enfermedad viral transmitida por artrópodos que más morbilidad y mortalidad ocasiona mundialmente. En el mundo actual, esta arbovirosis se considera la décima causa de muerte sobre todo en edades pediátricas. Objetivo: Caracterizar el comportamiento clínico y de laboratorio del choque por dengue en niños a partir de un año de edad. Métodos: Se realizó un estudio de corte transversal. Se estudiaron 19 pacientes con diagnóstico de choque por dengue. Para el análisis estadístico se utilizaron medidas de resumen como frecuencias, porcentaje, rango, mediana y moda. Resultados: Los signos de choque por dengue predominaron en los pacientes mayores de 5 años, femeninos y blancos, normopesos con antecedentes de salud. La mayoría ingresó al cuarto día; la fiebre fue el principal motivo de ingreso. El aumento progresivo del hematocrito fue el principal signo de alarma, y la hipotensión sin otra manifestación de choque constituyó la manifestación clínica más frecuente. Las soluciones cristaloides fueron las más utilizadas con muy buena respuesta clínica. Conclusiones: Todos los pacientes evolucionaron satisfactoriamente; no hubo ningún fallecimiento por dengue a pesar de que la mayoría fueron hospitalizados durante la fase crítica de la enfermedad, existiendo una identificación adecuada de los signos de alarma, y un adecuado control y tratamiento de las formas clínicas de choque por dengue(AU)

Introduction: Dengue is the arthropod-borne disease causing the highest morbidity and mortality worldwide. This condition is currently considered the tenth leading cause of death in the world, mainly in pediatric ages. Objective: Characterize the clinical and laboratory behavior of dengue shock in children aged one year and over. Methods: A cross-sectional study was conducted of 19 patients diagnosed with dengue shock. Statistical analysis was based on the summary measurements frequency, percentage, range, median and mode. Results: Dengue shock signs prevailed in white female patients aged over five years, of normal weight and with a history of good health. Most were admitted on the fourth day; fever was the main reason for admission. Gradual hematocrit increase was the main warning sign, whereas hypotension without any other shock symptom was the most common clinical manifestation. Crystalloid solutions were the most frequently used, with a very good clinical response. Conclusions: All the patients evolved satisfactorily; no death occurred due to dengue, despite the fact that many patients were admitted during the critical stage of the disease; warning signs were appropriately identified and clinical manifestations of dengue shock were controlled and treated(AU)

RESUMO

Caesarean section is one of the most common surgical procedures worldwide. Arterial hypotension is the most prevalent adverse effect after spinal anaesthesia. Various methods have been used to prevent or treat hypotension. Since there is no treatment 100% effective by itself, a multimodal management is required to achieve an optimum balance and avoidance of hemodynamic imbalance. Strategies to avoid this side effect are analyzed on the basis of the best evidence available so far, summarized as mechanical factors, anesthetics, fluids and vasopressors. After spinal anaesthesia for caesarean section, the best strategy available for prevention of hypotension appears to be the combination of crystalloids along with an alpha 1 agonist vasopressor.
