dc.description.abstractThe optimal treatment of septic shock remains controversial. In order to evaluate the efficacy of fluid resuscitation and corticosteroid administration, the following experimental study was undertaken. Forty-five puppies (1.6–5.4 kg) were randomly divided into 9 groups generated by combining 3 different fluid regimens and 3 different timings for steroid administration. Arterial, venous, and pulmonary artery catheterization allowed continuous hemodynamic and metabolic monitoring. Septic shock was achieved by a slow bolus infusion of 10 9 /kg Escherichia coli organisms. Methylprednisolone (30 mg/kg) was administered either 30 min before bacterial infusion, at the time of shock, or 30 min after shock. When cardiac output dropped to less than 50% of control values, 1 of the 3 following fluid resuscitation regimens was begun: 5% albumin in lactated Ringer's (LR) at 35% of the estimated blood volume (EBV), LR at 105% EBV, or 5% albumin in LR at 105% EBV. When all the groups were combined, early steroid treatment was more effective than delayed therapy, yielding respective survival rates of 47% and 7% at 180 min. Similarly, the large-volume resuscitation groups achieved a 43% survival rate compared to 13% for the smaller fluid protocols. Neither early steroid therapy nor large volume fluid therapy was shown by itself to increase survival, however. Despite steroid pretreatment, none of the puppies given the lower-volume infusion survived. Also, despite large-volume fluid resuscitation, there were no survivors when this was combined with steroid treatment that was delayed 30 min. Only by combining early steroid administration with large-volume fluid therapy was a markedly increased survival rate achieved: 60% with simultaneous steroid treatment, and 70% with steroid pretreatment. A definite increase in animal survival has, therefore, been shown in the acute period of severe septic shock using a combination of high-volume fluid resuscitation and the early administration of steroids. Le meilleur traitement du choc septique prête encore à controverse. Pour le déterminer, une étude expérimentale a été entreprise de manière à apprécier l'efficacité de la compensation liquidienne et celle des corticoïdes. Pour ce faire, 45 chiots (1,6–5,4 kg) furent randomisés en 9 groupes en combinant l'administration de 3 types de liquide et celles des stéroïdes à 3 moments différents. Le cathétérisme artériel, veineux et celui de l'artère pulmonaire permirent l'étude continue de l'hémodynamique et des métabolismes. Le choc septique fut provoqué par l'injection lente d'un bolus constitué de 10 9 /kg d'E. Coli. Le méthylprednisolone (30 mg/kg) fut employé 30 minutes avant l'injection, au moment du choc ou encore après le choc. Dès que le débit sanguin fut réduit de la moitié, la réanimation par apport liquidien fut assurée suivant 3 protocoles différents: injection de solution de Ringer enrichi de 5% d'albumine (35% du volume sanguin ou 105% du volume sanguin), solution de Ringer pur (105% du volume sanguin). Les résultats furent les suivants: l'administration précoce des stéroïdes fut plus efficace que l'administration tardive, se traduisant par un taux respectif de survie de 47% dans le premier cas et de 7% dans la seconde éventualité. De façon identique, l'injection importante de liquide se solda par un taux de survie de 43% alors que celui de l'injection limitée ne dépassa pas 7%. Cependant, ni la corticothérapie précoce, ni la compensation liquidienne importante n'augmenta par elle-même la survie. Aucun des chiots qui furent soumis à la corticothérapie précoce mais ne reçurent que peu de liquide ne survécut. Il en fut de même lorsque le chiot reçut un apport liquidien important et fut soumis à la corticothérapie tardive. C'est seulement en combinant la corticothérapie précoce et un apport liquidien important que le taux de survie fut amélioré: 70% quand la corticothérapie fut entreprise avant le choc, 60% lorsque les stéroïdes furent injectés au moment ou le choc fut provoqué. Le choc est susceptible d'être jugulé seulement par l'administration précoce de corticoïdes et par un apport liquidien important; telle est la conclusion des auteurs. El tratamiento óptimo del shock séptico sigue siendo motivo de controversia. Con el objeto de evaluar la eficacia de la resucitación con líquido y la administración de corticoesteroides, se acometío el siguiente estudio experimental. Cuarenta y cinco cachorros (1.6–5.4 kg) fueron divididos al azar en 9 grupos generados por la combinación de 3 diferentes regímenes de líquidos y 3 diferentes programas para la administración de esteroides. El cateterismo arterial, venoso y de arteria pulmonar permitió la monitoría continua hemodinámica y metabólica. El shock séptico fue inducido mediante la infusión lenta de un bolo de 10 9 /kg de microorganismos E. coli . Se administró metilprednisolona (30 mg/kg) 30 minutos antes de la infusión bacteriana, o en el momento del shock, o 30 minutos después del shock. Una vez que el débito cardiaco hubo descendido a menos del 50% de los valores de control, uno de tres regímenes de resucitación fue iniciado: albúmina al 5% en lactato de Ringer (LR) a razón de 35% del volumen sanguíneo estimado (VSE), LR a razón de 105% VSE, o albúmina al 5% en LR a razón de 105% VSE.en_US
