sepsis Flashcards
systemic inflammatory response (SIRS) criteria sens/ spec
These criteria are well known to have poor sensitivity and specificity for the presence of sepsis syndromes.
systemic inflammatory response (SIRS) criteria
Fever > 38°C (100.4°F) or< 36°C (96.8°F)
HR> 90
RR> 20 or PaCO 2 of less than 32 mm Hg
WBC (>12,000/µL or < 4,000/µL or >10% immature band forms)
*Need 2 or more
systemic inflammatory response (SIRS) criteria (PaCO 2)
(PaCO 2) of less than 32 mm Hg
systemic inflammatory response (SIRS) criteria fever
Fever > 38°C (100.4°F) or less than 36°C (96.8°F)
systemic inflammatory response (SIRS) criteria WBC
WBC (>12,000/µL or < 4,000/µL or >10% immature band forms)
Sepsis is defined as
a patient who has a potential infectious cause for the SIRS response.
A patient is said to have severe sepsis if
meet criteria for sepsis and have sepsis-induced organ dysfunction or tissue hypo perfusion.
Sepsis-induced organ dysfunction or tissue hypo perfusion examples
hypotension
kidney failure,
AMS
elevated lactate > than 4 mmol/L
The Centers for Medicare and Medicaid Services (CMS) define end-organ dysfunction by the following criteria
Blood Pressure
(SBP)<90 mm Hg or mean arterial pressure <70 mm Hg or a SBP decrease >40 mm Hg or <2 SD
below normal for age or known baseline
CMS end-organ dysfunction creatinine
Creatinine > 2.0 mg/dl (176.8 mmol/L) or Urine Output < 0.5 ml/kg/hour for > 2 hours,
CMS end-organ dysfunction bilirubin
Bilirubin > 2 mg/dl (34.2 mmol/L),
CMS end-organ dysfunction plts
Platelet count < 100,000,
CMS end-organ dysfunction co-ags
Coagulopathy (INR >1.5 or aPTT >60 secs),
CMS end-organ dysfunction lactate
Lactate > 2 mmol/L (18.0 mg/dl)
Septic shock is defined as
persistently low BP despite the fluid
~ 30 mL/kg.
