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

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)

Temp > 38 or < 36ºC

Heart rate > 90

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)

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”
