Resumen
Los pilares terapéuticos del niño con shock séptico se mantienen en el tiempo, sin embargo, se han incorporado nuevos conceptos, siendo importante que el pediatra y el intensivista tengan conocimiento a cabalidad de ellos.
La reanimación con fluidos es una intervención fundamental, no obstante, aún no se ha establecido un tipo de fluido ideal, presentando cada uno limitaciones específicas, no existiendo evidencia sobre la superioridad de un tipo de fluido. Si a pesar de una adecuada resucitación con fluidos persiste el shock, el inicio de inótropos y/o vasopresores está indicado. En caso de refractariedad al uso de vasopresores, nuevos fármacos vasoactivos pueden ser empleados y el uso de hidrocortisona debe considerarse en niños con sospecha de insuficiencia suprarrenal.
Existe controversia respecto a la transfusión de glóbulos rojos o el nivel óptimo de glucemia, no existiendo consenso en el valor umbral para el uso de estos hemocomponentes o el inicio de insulina, respectivamente. Asimismo, la utilización de la hemofiltración de alto volumen (HFAV)aún permanece controversial, requiriendo mayores estudios para su recomendación en forma rutinaria en el curso de un shock séptico refractario. El soporte nutricional es primordial, ya que la desnutrición es una grave complicación que debe ser prevenida y tratada adecuadamente.
El objetivo de la presente revisión es entregar una actualización en los más recientes avances en tratamiento del shock séptico en la población pediátrica.
Essential therapeutic principles in children with septic shock persist over time, although some new concepts have been recently incorporated, and fully awareness of pediatricians and intensivists is essential. Fluid resuscitation is a fundamental intervention, but the kind of ideal fluid has not been established yet, as each of these interventions has specific limitations and there is no evidence supportive of the superiority of one type of fluid. Should septic shock persists despite adequate fluid resuscitation, the use of inotropic medication and/or vasopressors is indicated. New vasoactive drugs can be used in refractory septic shock caused by vasopressors, and the use of hydrocortisone should be considered in children with suspected adrenal insufficiency, as it reduces the need for vasopressors. The indications for red blood cells transfusion or the optimal level of glycemia are still controversial, with no consensus on the threshold value for the use of these blood products or the initiation of insulin administration, respectively. Likewise, the use of high-volume hemofiltration is a controversial issue and further study is needed on the routine recommendation in the course of septic shock. Nutritional support is crucial, as malnutrition is a serious complication that should be properly prevented and treated. The aim of this paper is to provide update on the most recent advances as concerns the treatment of septic shock in the pediatric population.
