dc.description.abstractShock states continue to carry a high mortality rate in the pediatric age group. Using a puppy model, we measured the initial metabolic response to hemorrhagic shock and to 3 resuscitation regimens: whole blood 1∶1 (replacement∶shed), lactated Ringer's 3∶1, and 5% albumin in lactated Ringer's 1∶1. Despite the immature nature of the puppy's enzyme, cardiovascular, and nervous systems, responses very similar to those in adult animals were seen. Serum glucose and free fatty acids rose during shock and declined with resuscitation as cardiac output returned toward normal. Serum lactate levels rose similarly but continued to rise for a short period after resuscitation and were associated with a further fall in pH consistent with “hidden acidosis.” Only small changes were noted in triglyceride and cholesterol levels. The metabolic responses noted following each of the 3 resuscitation protocols were similar. This study suggests that the immature animal responds to hemorrhagic shock in ways similar to the adult. The better initial hemodynamic response to resuscitation with high-volume lactated Ringer's or lactated Ringer's with 5% albumin was offset by the better buffering capacity of blood resuscitation. All 3 regimens were equally efficacious in providing initial metabolic recovery in this experimental hemorrhagic shock model. Les états de choc s'accompagnent d'une mortalité élevée chez les enfants. En ayant recours à l'expérimentation chez le chiot, les auteurs ont mesuré les modifications métaboliques initiales en réponse au choc hémoragique et à sa correction par 3 agents différents: sang complet (1∶1), solution de Ringer (3∶1) et solution de Ringer enrichie de 5% d'albumine. Malgré la nature immature des enzymes du chiot, du système cardio-vasculaire et du système nerveux, les réponses furent identiques à celles observées chez le chien adulte. Le glucose et les acides gras libres s'élevèrent au cours du choc et s'abaissèrent lors de la réanimation dès que le débit cardiaque revint à la normale. Les niveaux du lactate sanguin s'élevèrent de la même manière mais l'élévation continua pendant une courte période après la réanimation, cependant que le pH s'abaissait, démasquant une “acidose cachée”. Les taux des triglycérides et du cholestérol furent seulement discrètement altérés. Les réponses métaboliques étudiées en fonction des 3 méthodes de réanimation furent identiques. Cette étude suggère que le chiot répond de la même façon que le chien adulte au choc hémorragique et que les 3 méthodes de réanimation employant chacune des agents différents ont une efficacité identique. Los estados shock mantienen una elevada mortalidad en los grupos de edad pediátrica. Utilizando un modelo de shock en cachorros, se determinó la respuesta metabólica inicial al shock hemorrágico y a tres diferentes regimenes de resucitación: sangre total 1∶1 (reemplazo: pérdida), lactato de Ringer 3∶1, y albúmina al 5% en lactato de Ringer 1∶1. A pesar de la naturaleza inmadura de los sistemas enzimático, cardiovascular y nervioso del cachorro, las respuestas fueron muy similares a las observadas en animales adultos. La glucosa sérica y los ácidos grasos libres ascendieron durante el shock y declinarion en la medida que el débito cardiaco retornaba a lo normal. Los niveles de lactato sérico ascendieron en forma similar, pero continuaron su ascenso por un corto periodo de tiempo después de la resucitación, encontrándose asociados con una caida adicional del pH consistente con “acidosis oculta”. Sólo se presentaron cambios leves en los niveles de triglicéridos y colesterol. Las respuestas metabólicas observadas en cada uno de los tres protocolos de resucitación fueron similares. Este estudio sugiere que el animal inmaduro responde al shock hemorrágico de manera similar al adulto. La mejor respuesta hemodinámica inicial a la resucitación con altos volúmenes de lactato de Ringer o con lactato de Ringer con albúmina al 5%, fue compensada con una mejor capacidad de amortiguación observada en la resucitación con sangre. Los tres regimenes fueron igualmente eficaces en lograr la recuperación metabólica inicial en este modelo experimental de shock hemorrágico.en_US
