CHOQUE DISTRIBUTIVO EN PEDIATRIA PDF

Santiago, Chile. Stress hyperglycemia is frequently diagnosed in septic patients in critical care units ICU and it is associated with greater illness severity and higher morbimortality rates. In response to an acute injury, high levels of counterregulatory hormones such as glucocorticoids and catecholamines are released causing increased hepatic gluconeogenesis and insulin resistance. Furthermore, during sepsis, proinflammatory cytokines also participate in the pathogenesis of this phenomenon. Septic patients represent a subtype of the critical ill patients in the ICU: this metabolic disarrangement management strategies and insulin therapy recommendations had been inconsistent. In this article, we describe the pathophysiological mechanisms of stress hyperglycemia in critical patients including the action of hormones, inflammatory cytokines and tissue resistance to insulin.

Clinical practice parameters for hemodynamic support of pediatric and neonatal patients in septic shock. Joseph A. Carcillo, MD, Alan I. A fisiopatologia do choque e a resposta a terapias variam de acordo com a idade do paciente. Background: the Institute of Medicine has called for the development of clinical guidelines and practice parameters to develop "best practice" and potentially improve patient outcome. Objective: to provide American College of Critical Care Medicine clinical guidelines for hemodynamic support of neonates and children with septic shock.

Setting: individual members of the Society of Critical Care Medicine with special interest in neonatal and pediatric septic shock were identified from literature review and general solicitation at Society of Critical Care Medicine Educational and Scientific Symposia Methods: the MEDLINE literature database was searched with the following age-specific keywords: sepsis, septicemia, septic shock, endotoxemia, persistent pulmonary hypertension, nitric oxide, and extracorporeal membrane oxygenation.

More than 30 experts graded literature and drafted specific recommendations by using a modified Delphi method. More than 30 more experts then reviewed the compiled recommendations. The task-force chairman modified the document until Results: only four randomized controlled trials in children with septic shock could be identified. None of these randomized trials led to a change in practice. Clinical practice has been based, for the most part, on physiologic experiments, case series, and cohort studies.

Shock pathophysiology and response to therapies is age specific. For example, cardiac failure is a predominant cause of death in neonates and children, but vascular failure is a predominant cause of death in adults. Inotropes, vasodilators children , inhaled nitric oxide neonates , and extracorporeal membrane oxygenation can be more important contributors to survival in the pediatric populations, whereas vasopressors can be more important contributors to adult survival.

Conclusion: American College of Critical Care Medicine adult guidelines for hemodynamic support of septic shock have little application to the management of pediatric or neonatal septic shock. Studies are required to determine whether American College of Critical Care Medicine guidelines for hemodynamic support of pediatric and neonatal septic shock will be implemented and associated with improved outcome.

To describe abnormalities in coagulation and fibrinolysis in septic shock with purpura and to assess the relationship between plasma plasminogen activator inhibitor-1 PAI-1 concentrations and multiple organ system failure MOSF.. Observational study in the pediatric intensive care unit of a tertiary care hospital. The presence of early MOSF was assessed at admission in 15 children with septic shock and purpura consecutively admitted to the pediatric intensive care unit. Blood samples were taken to determine coagulation and fibrinolysis parameters.. At admission, MOSF was diagnosed in 7 patients Coagulation parameters were generally affected but statistically significant differences were found only in concentrations of fibrinogen and antithrombin III, which were lower in patients with MOSF than in those without organ dysfunction. These data indicate that impaired fibrinolysis could play a major role in the development of MOSF in children with septic shock and purpura..
