All of them died secondary to sepsis Pope John-Paul II Mariana Bridi Costa, Brazilian model Etta James, singer
Practical Sepsis Curtis J. Merritt D.O. Chief Internal Medicine Resident Danville Regional Medical Center Danville Virginia
With that in mind the single goal of this presentation is to demonstrate a stepwise approach to make sepsis practical

SEPSIS • A brief review of the last 12 years…
By The Numbers • Annual cost = $16.7 billion in the US in 2000 • 1,400 people die each day from sepsis • Roughly 2 million cases per year • 30% dying within one month of diagnosis • 80% of patients who die from major injuries are actually killed by sepsis Survivingsepsis.org
12 years ago Dr. Emanuel Rivers published in the NEJM an article that would change our approach to sepsis
In that study, Dr. Rivers and colleagues proved that early recognition and aggressive treatment of severe sepsis and septic shock resulted in a 16% reduction in absolute mortality. • That translates to NNT = 6 - 8 N Engl J Med 2001; 345:1368-1377: November 8, 2001
If you fancy a journey… • We have to be willing to evolve with the evidence based medicine and be able to look at it critically • We have to be open to the idea of aggressive management • We have to put away our old notions of the “look” of sepsis

The Rub • Many physicians do not use the current definition of sepsis despite attempts to standardize terminology and diagnostic criteria. Indeed, only 17% of clinicians agree on a definition of sepsis (12), and this disparity results in missed diagnosis and delayed treatment. The challenges include: • Lack of awareness of frequency and mortality rate of sepsis • No universally accepted definition of sepsis • No single or combination of tests or markers for a reliable diagnosis of sepsis • Need for earlier diagnosis and treatment of septic patients • Lack of adequate healthcare professional training in the diagnosis and treatment of sepsis *http://www.survivingsepsis.org/Background/Pages/barcelona_declaration.aspx
Sepsis model • To understand the definition we have to understand the process
The River… What do you notice about the river? -fast -churning -high rate of aeration -large volume in a confined space -faces of horror
This river is very similar to normal physiology -fast turn over -adequate O2 -adequate volume
Now picture that same volume in that river after the rock walls have been removed and the width of the channel is much larger Much like a stagnant swamp
Now that same volume is moving through a much larger area So… What happens to flow? What happens to O2 content? What happens to the fish?
In sepsis, toxins and cytokines produce a profound vasodialation and the venous side of the circulator system experiences a low-flow, low O2 state But that’s not the whole story…

Orthogonal polarization spectral imaging Normal No embolisms Flow speed is adequate that individual RBCs can’t be seen Normal vessel caliber Rev. bras. ter. intensiva vol.23 no.3 São Paulo July/Sept. 2011

Microthrombi • Stagnant flow • Small caliber Rev. bras. ter. intensiva vol.23 no.3 São Paulo July/Sept. 2011
This is why peripheral hypoxia (i.e. SvO2) can continue despite normal vitals, CVP etc. Rev. bras. ter. intensiva vol.23 no.3 São Paulo July/Sept. 2011
First things first • We have to put our old definitions of sepsis away • We have to realize that sepsis is often difficult to diagnose without a stepwise approach
