  1. Sepsis:Pathophysiology & Current Management Guidelines Sarah Leyland Practice Educator General ICU

  2. Publications:

  3. Definitions – Changed in 2016 • Seymour et al • (2016) • Singer et al (2016) • Sepsis – “life threatening organ dysfunction caused by disregulated host response to infection” (Singer et al 2016) • Organ dysfunction = change in SOFA score (Seymour et al 2016) • Septic Shock = subset of sepsis in which profound circulatory, cellular and metabolic abnormalities are assoc. with a greater risk of mortality than sepsis alone (Singer et al 2016)

  4. Recognition (ward / outreach qSOFA) Singer et al (2016)

  5. Recognition (ITU) SOFA Singer et al (2016)

  6. Singer et al (2016)

  7. Don’t use the term SIRS: • Singer et al (2016) concluded SIRS did not discriminate enough • Gotts and Mattay (2016) pancreatitis, tissue ischemia, trauma, surgical tissue injury, burns, thromboembolism, vasculitis, drug reactions, autoimmune and neoplastic processes such as lymphoma and hemophagocyticlymphohistiocytosis also cause SIRS (or sterile inflammatory conditions)

  8. Neuroendocrine activation and inflammatory mediators Complex series of responses leading to: • Maldistribution of circulating volume • Systemic vasodilation, venous obstruction, tissue oedema, endothelial damage, selective vasoconstriction • Imbalance of oxygen supply and demand • Increased O2 demand, oxygen extraction defects, microvascular abnormalities, V/Q mismatch • Alterations of metabolism, including glucose • Hyperglycaemia, hypermetabolism, protein catabolism and gluconeogenesis, insulin resistance, hepatic dysfunction, lactate production

  9. What changes will you see in your patient?

  10. Initial management: • Lipcsey et al (2015)

  11. ‘Survive Sepsis’ • UK initiative – education programme • The Sepsis Six • High flow oxygen • Take blood cultures • Give IV antibiotics • Start IV fluid resuscitation • Check lactate • Monitor hourly urine output • All to be completed within 1 hour of suspected sepsis diagnosis

  12. Lipcsey et al (2015)

  13. NICE Sugar http://www.uptodate.com/contents/glycemic-control-and-intensive-insulin-therapy-in-critical-illness http://www.criticalcarenutrition.com/docs/tools/NIBBLE_Issue%2013_Sepsis%20Nutrition_Feb%202014.pdf Gotts and Matthay (2016)

  14. In hospital: • Don’t assume type of shock… result maybe delay in treatment • Secondary infection – central lines, urethral catheters, peripheral access, VAP • Blood cultures – ***ONLY via line if very important source of access*** i.e Hickman line / Tesio / PICC • Long terms effect life changing illness • CVS effect up to 5 years later • Vancomycin - please be careful! There are lots of incidents with this drug.
