Treatment according to the early and later stages of sepsis
The cornerstone of emergency management of sepsis is early, goal directed therapy, plus lung protective ventilation, broad spectrum antibiotics, and possibly activated protein C (Table 2). A randomized controlled trial was conducted in which patients with severe sepsis and septic shock received early, goal directed, protocol guided therapy during the first 6 hours after enrollment or the usual ...
متن کاملBlood transfusions in septic shock: is 7.0g/dL really the appropriate threshold?
OBJECTIVE To evaluate the immediate effects of red blood cell transfusion on central venous oxygen saturation and lactate levels in septic shock patients with different transfusion triggers. METHODS We included patients with a diagnosis of septic shock within the last 48 hours and hemoglobin levels below 9.0 g/dL Patients were randomized for immediate transfusion with hemoglobin concentration...
متن کاملA survey of Canadian intensivists' resuscitation practices in early septic shock
INTRODUCTION Recent evidence suggests that early, aggressive resuscitation in patients with septic shock reduces mortality. The objective of this survey was to characterize reported resuscitation practices of Canadian physicians caring for adult critically ill patients with early septic shock. METHODS A scenario-based self-administered national survey was sent out to Canadian critical care ph...
متن کاملCentral Venous-To-Arterial CO2-Gap May Increase in Severe Isovolemic Anemia
Despite blood transfusions are administered to restore adequate tissue oxygenation, transfusion guidelines consider only hemoglobin as trigger value, which gives little information about the balance between oxygen delivery and consumption. Central venous oxygen saturation is an alternative, however its changes reflect systemic metabolism and fail to detect regional hypoxia. A complementary para...
متن کاملVenoarterial carbon dioxide gradient utility as a criterion for blood transfusion at the intensive care unit
Methods Patients within their first 12 hours from admission to the intensive care unit (ICU) during the hemodynamic optimization protocol in which blood transfusion was decided to rise the Sv02 after hemodynamic optimization: central venous pressure (CVP)>8 mmHg, mean arterial pressure (MAP)>65 mmHg, peripheral oxygen saturation (Sp02) >90%. Pre and post transfusion hemoglobin, venous oxygen sa...
