Shock and Sepsis 2 of 2 William Whitehead, M.D., Ph.D. Department of Anesthesiology
Management “Surviving Sepsis Campaign”: An international group of experts published in 2004 the first guidelines for the bedside clinician to use to improve outcomes in severe sepsis and septic shock. Therapeutic Bundles
What are “bundles”? A group of interventions related to a disease that, when implemented together, result in better outcomes than when implemented individually. The science behind the elements of the bundle is so well-established that their implementation should be considered a generally accepted practice. Bundle components can easily be measured as completed or not completed. As such, the overall bundle – all the elements taken together – can also be measured as completed or not completed.
Patient randomized N=263 Early goal directed therapy N=130 Standard therapy N=133 CVP > 8-12 mm Hg MAP > 65 mm Hg Urine Output > 0.5 ml/kg/hr CVP > 8-12 mm Hg MAP > 65 mm Hg Urine Output > 0.5 ml/kg/hr ScvO 2 > 70% SaO 2 > 93% Hct > 30% Antibiotics given at discretion of treating clinicians As soon as possible Mean 6.2hrs ICU MDs blinded to study treatment NEJM 2001;345:1368-77. At least 6 hours of EGDT Mean 8hrs Transfer to ICU
Therapy Across the Sepsis Continuum. Chest 1992;101:1644. SepsisSIRS Severe Sepsis Septic Shock Early Goal Directed Therapy Antibiotics and Source Control Early Goal-Directed Therapy (EGDT): involves adjustments of cardiac preload, afterload, and contractility to balance O 2 delivery with O 2 demand *
CVP: central venous pressure MAP: mean arterial pressure ScvO 2 : central venous oxygen saturation Early Goal- Directed Therapy NEJM 2001;345:1368-77.
Lactate: An Indicator of Tissue Perfusion Serum lactate levels are used to assess the disease severity and adequacy of global tissue perfusion By-product of anaerobic metabolism if tissue hypoxia exists Interpretation of elevated blood lactate levels in sepsis is limited by several important factors1: Production of elimination Increasing glycolysis Inhibition of pyruvate metabolism Global changes Bakker J, Gris P, Conerfils M, et al.
