Definition of
Sepsis
SIRS = 2 or more of the following:
Temp > 38 or < 36ºC
Heart rate > 90
Resp rate > 20 or PaCO2 < 30 mmHg
WCC > 12 or < 4
Sepsis = SIRS with identified organism
Severe sepsis = sepsis with organ dysfunction
- hypoperfusion – lactate >4 or impaired mentation
- hypotension – SBP < 90, MAP < 65, drop of 40mmHg from baseline
Septic shock = sepsis with hypotension after adequate fluid resuscitation
Old Sepsis Definitions (1992, 2001)
SIRS = 2 or more of the following:
Temp > 38 or < 36ºC
Heart rate > 90

Septic shock = sepsis with hypotension after adequate fluid resuscitation
Old Sepsis Definitions (1992, 2001)
Sepsis = life threatening organ dysfunction caused
by a dysregulated host response to infection.
Organ dysfunction quantified by Sequential Organ
Failure Assessment (SOFA).
New Sepsis Definitions (2016)
The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis – 3) – Singer et al, JAMA 2016;315(8):801-810
Sepsis Quick SOFA Score (qSOFA)
2 or more:
RR ≥ 22/min
Altered mentation
SBP ≤ 100mmHg
The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis – 3) – Singer et al, JAMA 2016;315(8):801-810
Hospital Mortality = 10%
Septic Shock
Vasopressor requirement
post fluid resuscitation
Lactate > 2mmol/L
The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis – 3) – Singer et al, JAMA 2016;315(8):801-810
Hospital Mortality = 40%
qSOFA does not replace SIRS in the definition of sepsis – Vincent et al, Critical Care 2016 20:210
More specific
Clinically more helpful
Doesn’t require lab tests
Facilitates earlier recognition
Greater consistency with
research and trials
IV antibiotics –
when?
Well + qSOFA score < 2: sample first?
qSOFA ≥ 2 or Septic Shock: within 1 hour
Well + qSOFA score < 2: sample first?
qSOFA ≥ 2 or Septic Shock: within 1 hour
Duration of hypotension before the initiation of effective antimicrobial therapy is the critical determinant of survival in human septic shock – Kumar et al , Critical Care Medicine 2006 Jun;34(6):1589-96
For every hour
a patient with
septic shock is
without
appropriate
antibiotic
therapy, their
mortality rate
increases by
7.6%

“Sometimes the
hardest decision is
when not to operate”
My 1st Line
“I totally support a decision to
not operate on this patient”
We are going to
operate!
Advance Resuscitation Planning
ICU – full support (+/- transfer)
ICU – limited support
Ward based care (like #NOF patient)
“Sometimes the
hardest decision is
to limit care”
My 2nd Line
“We are going to try to get you through this
operation/illness, however, if you begin to
take steps backwards and your organs
begin to shut down, we will move to
keeping you comfortable”
