From Early Goal-Directed Therapy to Late(r) Scvo2 Checks

[摘要] Figures Figure 1 Suggested algorithm for hemodynamic management of septic shock using S cvo ₂. D o ₂ = oxygen delivery; Hb = hemoglobin; MAP = mitogen-activated protein; Sa o ₂ = oxygen saturation; S cvo ₂ = central venous oxygen saturation; VAPCO₂ = venoarterial partial pressure of carbon dioxide. Septic shock is the typical form of distributive shock, characteristically associated with a hyperkinetic (high cardiac output) state and normal or high mixed venous oxygen saturation (S vo ₂).¹ Rivers et al² introduced the concept of early goal-directed therapy in septic shock, made on the basis of measurements of central venous oxygen saturation (S cvo ₂), which are more easily obtained than S vo ₂, especially in an ED. This strategy, which included giving more fluids, transfusions, and dobutamine when the S cvo ₂ was
