Points for discussion
• Recognition / diagnosis of sepsis • Management of sepsis
![Page 10: Small ED Quality &Safety Teleconference July 2017 · Case 1 - ED assessment • Further hx • Multiple episodes of vomiting & diarrhoea over last 2 days • Generalised abdominal](https://reader034.vdocuments.net/reader034/viewer/2022042100/5e7d35b35493ec2afb03a643/html5/thumbnails/10.jpg)
What is sepsis? Definition from “Sepsis 3” Guidelines 2016
• Sepsis is life threatening organ dysfunction caused by a dysregulated
host response to infection
• Septic shock is a subset of sepsis where underlying circulatory and cellular/metabolic abnormalities are profound
enough to substantially increase mortality, i.e. persistent hypotension needing vasopressors to keep MAP > 65mmHg
AND serum lactate > 2mmol/L despite adequate fluid resuscitation
• (NB: “Severe sepsis” is no longer a separate group)
![Page 11: Small ED Quality &Safety Teleconference July 2017 · Case 1 - ED assessment • Further hx • Multiple episodes of vomiting & diarrhoea over last 2 days • Generalised abdominal](https://reader034.vdocuments.net/reader034/viewer/2022042100/5e7d35b35493ec2afb03a643/html5/thumbnails/11.jpg)
Recognising sepsis • Sepsis is life threatening organ dysfunction caused by a
dysregulated host response to infection
How to identify organ dysfunction? • Sepsis-3 uses an increase in SOFA score of ≥ 2 points Calculating the SOFA score (SOFA = Sequential [sepsis related] Organ Failure Assessment)
SOFA Parameters include • GCS • PaO2 / FiO2
• Platelet count • Bilirubin • Creatinine • Urine output • MAP & inotrope requirements
Is this really practical for ED?
![Page 12: Small ED Quality &Safety Teleconference July 2017 · Case 1 - ED assessment • Further hx • Multiple episodes of vomiting & diarrhoea over last 2 days • Generalised abdominal](https://reader034.vdocuments.net/reader034/viewer/2022042100/5e7d35b35493ec2afb03a643/html5/thumbnails/12.jpg)
Recognising sepsis in the ED • Sepsis is life threatening organ dysfunction caused by a
dysregulated host response to infection
How to identify organ dysfunction in the ED? • Sepsis-3 also defines a q-SOFA score for use in ED
qSOFA (“quick-SOFA”) score 1 pt for each of the following present:
• Hypotension SBP ≤ 100
• Altered mental state GCS < 15
• Tachypnoea RR ≥ 22
In ED, qSOFA score of ≥ 2 is considered significant
qSOFA score has been shown to identify patients who are likely to have prolonged ICU stay or die in hospital

Sepsis & “SIRS criteria” Previous definitions of sepsis, severe sepsis & septic shock
used SIRS criteria (Surviving Sepsis campaign 2012 definitions) • Sepsis is the presence of an infection with evidence of SIRS
i.e. presence of ≥ 2 of the following SIRS criteria • Temp > 38.3°C or < 36°C (in adults) • HR > 90 • RR > 20 or PaCO2 < 32mmHg • WCC > 12 or < 4 (or > 10% immature band forms) • BSL > 7.7 mmol/L (in absence of diabetes) • Altered mental state
![Page 14: Small ED Quality &Safety Teleconference July 2017 · Case 1 - ED assessment • Further hx • Multiple episodes of vomiting & diarrhoea over last 2 days • Generalised abdominal](https://reader034.vdocuments.net/reader034/viewer/2022042100/5e7d35b35493ec2afb03a643/html5/thumbnails/14.jpg)
Severe sepsis & septic shock • Severe sepsis is sepsis with organ dysfunction i.e. at least one of
the following variables present • Arterial hypotension
• SBP < 90, MAP < 70 or systolic BP reduced > 40mmHg from baseline • Arterial hypoxaemia with new pulmonary infiltrates (PaO2 : FiO2 ratio < 300) • New or increased oxygen requirements to maintain sats > 90% • Acute oliguria (UO < 0.5mL/kg/hr for > 2 hr) OR serum Cr > 177 μmol/L • Coagulation abnormalities (INR > 1.5, APTT > 60) • Thrombocytopaenia (plt < 100) • Lactate > 2.0 mmol/L (after fluid resuscitation)
• Septic shock is a subset of severe sepsis, and is defined as • Arterial hypotension persisting for >1 hr despite adequate fluid resus • Serum lactate > 4.0 mmol/L (after fluid resuscitation)

![Page 24: Small ED Quality &Safety Teleconference July 2017 · Case 1 - ED assessment • Further hx • Multiple episodes of vomiting & diarrhoea over last 2 days • Generalised abdominal](https://reader034.vdocuments.net/reader034/viewer/2022042100/5e7d35b35493ec2afb03a643/html5/thumbnails/24.jpg)
Lessons to learn • Importance of maintaining sepsis pathway once started
• Regular observations
• Need to review diagnosis if pt is not improving
• Early antibiotics is important in sepsis
