Rita de Cássia Silveira Clarice Giacomini Renato Soibelmann Procianoy About the authors

The nonspecific presentation of neonatal sepsis and systemic inflammatory response syndrome preceding septic shock delay the early diagnosis of septic shock and increase its mortality rate. Early diagnosis involves suspecting septic shock in every newborn with tachycardia, respiratory distress, difficult feeding, altered tonus and skin coloration, tachypnea and reduced perfusion, specially in case of maternal peripartum infection, chorioamnionitis or long-term membranes rupture. This article aims to review current knowledge on neonatal period peculiarities, fetal circulation dynamics, and the pregnancy age variable. Newborn septic shock is not just a small adult shock. In the newborn, the septic shock is predominantly cold and characterized by reduced cardiac output and increased systemic vascular resistance (vasoconstriction). Time is fundamental for septic shock reversion. The indexed-databases literature review provides subside for the newborn management.
