- BACKGROUND:Once a septic condition is progressing, administration of steroids in the pro-inflammatory phase of septic shock ought to yield maximal effect on the subsequent, devastating inflammatory response. Recently, a retrospective study showed that early initiation of corticosteroid therapy improved survival in septic shock. We aimed to prospectively evaluate effects of early administrated hydrocortisone therapy on physiologic variables in a porcine model of septic shock.EXPERIMENT:Eight anesthetized pigs were given a continuous infusion of endotoxin during this 6h prospective, randomized, parallel-grouped placebo-controlled experimental study. At the onset of endotoxemic shock, defined as the moment when the mean pulmonary arterial pressure reached the double baseline value, the pigs were either given a single intravenous dose of hydrocortisone (5 mg kg−1) or the corresponding volume of saline.RESULTS:Mean arterial pressure and systemic vascular resistance index were significantly higher (both p<0.05), and heart rate was significantly lower (p<0.05), in the endotoxin+hydrocortisone group as compared to the endotoxin+saline group. Body temperature and blood hemoglobin levels increased significantly in the endotoxin+saline group (both p<0.05). Urinary hydrocortisone increased significantly in both groups (p<0.05). There were no significant differences in the plasma levels of TNF-alpha, IL-6 or nitrite/nitrate between the groups.CONCLUSION:Early treatment with hydrocortisone ameliorates some endotoxin mediated circulatory derangements, fever response and microvascular outflow. Our results suggest that these effects are not directly mediated by the pro-inflammatory cytokines TNF-alpha or IL-6, nor by NO.
