7. The physiological changes occurring in patients with severe sepsis and septic shock are myriad and include changes that are clearly detrimental such as decreased contractility of the left and right ventricle, increased venous capacitance, increased pulmonary vascular resistance, and capillary leak. Increased ventricular compliance and sinus tachycardia are likely adaptive responses allowing the ventricle to maintain, and even manifest increased cardiac input, following volume resuscitation in despite decreased contractility. The decreased arteriolar resistance may also be adaptive, although when profound, produces detrimental and potentially lethal hypotension.

9. This slide demonstrates radionuclide angiography in a patient during septic shock and following recovery. The top left panel shows end-diastole and demonstrates increased diastolic size of the ventricles (increased compliance), which is thought to be an adaptive mechanism. The top right image shows end-systole in this patient demonstrating a very low ejection fraction (little change in chamber size compared to end-diastole). The bottom two frames following recovery demonstrate a decrease in end-diastole volume, smaller ventricle at end systole, and therefore significant improvement in ejection fraction.
10. Effects of Dopamine, Norepinephrine, and Epinephrine on the Splanchnic Circulation in Septic Shock See discussion on next slide Figure 2, page 1665, reproduced with permission from De Backer D, Creteur J, Silva E, Vincent JL. Effects of dopamine, norepinephrine, and epinephrine on the splanchnic circulation in septic shock: Which is best? Crit Care Med. 2003;31:1659-1667.
11. Considerable data (such as that shown on the previous slide) indicates that epinephrine, although a combined inotrope/vasopressor, is not the best initial vasopressor of choice because of concerns with decrease in splanchnic blood flow. The study above comparing dopamine, norepinephrine, and epinephrine in moderate shock, and norepinephrine and epinephrine in severe shock supports epinephrine-induced decrease in splanchnic blood flow.

14. The Importance of Early Goal-Directed Therapy for Sepsis-induced Hypoperfusion See discussion on next slide Adapted from Table 3, page 1374, with permission from Rivers E, Nguyen B, Havstad S, et al. Early goal-directed therapy in the treatment of severe sepsis and septic shock. N Engl J Med. 2001;345:1368-1377. In-hospital mortality (all patients) 0 10 20 30 40 50 60 Standard therapy EGDT 28-day mortality 60-day mortality NNT to prevent 1 event (death) = 6 - 8 Mortality (%)
15. The recommendations for initial resuscitation are centered around the Rivers trial (above) of early goal-directed therapy, which showed significant improvement in (a) hospital mortality, (b) 28-day mortality, and (c) 60-day mortality.
26. This picture demonstrates a 38-year-old man with pharyngitis who presents with high fever, leukocytosis, hypotension, elevated BUN/creatinine, and early evidence of coagulopathy who now has redness and swelling of the anterior neck and chest pain. An EKG obtained in this patient demonstrates a diffuse ST segment elevation (or PR depression) diagnostic of pericarditis, and in this case indicating the presence of mediastinitis requiring urgent operative drainage of the mediastinum in order to prevent mortality.

31. ScvO2 closely paralleled SvO2 but averaged 5 – 7% higher Reinhart K, et al. Intensive Care Med. 2004;30:1572-1578.
32. A central line is inserted in the right neck. CVP is 12 mm Hg. MAP is 70 mm Hg with vasopressor support. Lab results reveal elevated BUN and creatinine. Arterial gases reveal pH 7.22, PaCO2 28 torr, and PaO2 65 torr. Hematocrit is 32% and saturation is 94% with supplement oxygen. The central venous O2 saturation is 60%.

37. Cooper and colleagues compared equimolar amounts of sodium bicarbonate and normal saline in patients with vasopressor requiring lactic acidosis (pH range down to 7.15 with mean 7.23) and demonstrated that although pH was significantly increased with bicarbonate versus normal saline there was no difference in cardiac output. There was also no difference between the two groups as to weaning of vasopressors.

39. Circulating Vasopressin Levels in Septic Shock Figure 2, page 1755 reproduced with permission from Sharshar T, Blanchard A, Paillard M, et al. Circulating vasopressin levels in septic shock. Crit Care Med. 2003;31:1752-1758. See discussion on next slide
40. Vasopressin levels are elevated during the initial presentation of septic shock and then decrease to basal levels over the next 48 to 96 hours. Since vasopressin levels are expected to be a normal body response to hypotension, this occurrence has been labeled as relative vasopressin deficiency and has led to the use of vasopressin in patients with septic shock.

44. The largest randomized prospective trial done to study the effect of stress-dose steroids in septic shock is the “French multi-center trial,” which targeted “apriori” patients who did not respond to ATCH stimulation as the group that would likely benefit from steroid therapy (slide shows results in that group). This group represented 77% of the population, and in this group significant improvement in survival by Kaplan-Meier curve with logistic regression adjustment for other variables influencing survival was shown.
