Definition
- Sepsis = Infection + SIRS. The presence of systemic inflammatory syndrome (SIRS) is due to many factors. The presence of infection increases the chances of sepsis and increase the SIRS criteria .
- The endothelial dysfunction is the main trigger transforming the localized infection into systemic organ dysfunction
- There is no definitive biomarkers have been associated with the endothelial dysfunction of sepsis.
With sepsis, at least 1 of the following is typically included: [HOME]
- Hypoxemia (arterial oxygen tension [PaO2] < 72 mm Hg at fraction of inspired oxygen [FiO2] 0.21; overt pulmonary disease not the direct cause of hypoxemia)
- Oliguria (urine output < 30 mL or 0.5 mL/kg for at least 1 h)
- Mental status alteration
- Elevated plasma lactate level > 4mg
- Multiple organ dysfunction syndrome (MODS) is the presence of altered organ function in a acutely ill patient whom homeostasis cannot be maintained without intervention.
