Resumo

Introducción: La sepsis es una de las principales causas de morbilidad y mortalidad en la población pediátrica a nivel mundial, siendo la disminución del gasto cardiaco uno de los principales factores asociados a mortalidad. Se ha planteado la diferencia venoarterial de pCO2 como predictor de la función miocárdica en pacientes con sepsis, sin embargo hasta el momento no hay estudios en la población pediátrica que lo evalúen. Objetivo: Determinar la capacidad predictora y las características operativas de la diferencia venoarterial de pCO2, como predictor de disfunción miocárdica en pacientes pediátricos con sepsis severa y choque séptico. Métodos: Para alcanzar los objetivos del estudio, se llevo a cabo un estudio prospectivo de pruebas diagnósticas. Se realizó ecocardiograma y diferencia venoarterial de pCO2 en cada paciente, posteriormente se calculó las características operativas de la diferencia venoarterial de pCO2 para determinar su utilidad. Resultados: Se incluyeron 71 pacientes. La mediana de la diferencia venoarterial de pCO2 no fue significativamente mayor en los pacientes que tuvieron disfunción cardiaca en el ecocardiograma en comparación con los que no tuvieron disfunción. Se encontró una relación estadísticamente significativa de valores de 1,5 a 2,1 mmHg, como predictor negativo de disfunción miocárdica con una sensibilidad de 100% y una especificidad de 88%. Conclusiones: La diferencia venoarterial de pCO2 requiere de estudios mas extensos para determinar la probabilidad como predictor de disfunción miocárdica en pacientes pediátricos con sepsis severa y choque séptico, incluso cuando otros biomarcadores se encuentran dentro de límites normales.

Introduction: Sepsis is a major cause of morbidity and mortality in the pediatric population worldwide. It is widely known that low cardiac output is one of the main factors associated with mortality in pediatric sepsis. It has been suggested venoarterial pCO2 difference as predictor of myocardial function in patients with sepsis, however, to date no studies in children have been done to asses it. Objective: The aim of this study was to determine the predictive capacity and operational characteristics of venoarterial pCO2 difference as predictor of myocardial dysfunction in pediatric patients with severe sepsis and septic shock. Methods: In order to achieve the objectives of the study, it was performed a prospective study of diagnostic tests. Echocardiogram and venoarterial pCO2 difference were done to each patient, then the operating characteristics of the venoarterial difference of pCO2 were calculated, to determine its usefulness. Results: 71 patients were included. The median venoarterial pCO2 difference was not significantly higher in patients who had cardiac dysfunction on echocardiography compared with those with no dysfunction. A statistically significant relationship of values from 1.5 to 2.1 mmHg, as a negative predictor of myocardial dysfunction with a sensitivity of 100% and a specificity of 88% was found. Conclusions: The difference venoarterial pCO2 is not yet a good predictor of myocardial dysfunction in pediatric patients with severe sepsis and septic shock, even when other biomarkers are within normal limits.
