Sepsis Flashcards
Although SIRS has been shown to have poor sensitivity and specificity, it is still widely used. What are the SIRS criteria?
- Temperature greater than 38ºC or less than 36ºC
- HR greater than 90 BPM
- RR greater than 20 or PaCO2 less than 32 mm Hg
- WBC greater than 12,000 or less than 4,000 or greater than 10% immature bands
What is sepsis?
A syndrome in which the patient meets the SIRS criteria and has a potential infectious source
What is severe sepsis?
Sepsis with signs of end-organ dysfunction such as any one of the following:
•SBP less than 90 mm Hg or a drop in 40 mm Hg from baseline
•Creatinine greater than 2.0 mg/dl or decreased urine output (less than 0.5 ml/kg/hour for greater than 2 hours)
•Bilirubin greater than 2.0 mg/dl
•Platelet count less than 100,000
• INR greater than 1.5 or aPTT greater than 60 seconds
•Lactate greater than 2 mM
What is septic shock?
Persistently low blood pressure with severe sepsis despite fluid resuscitation at 30 ml/kg
One of the best indicators of risk stratification for sepsis patients is ______________.
lactate elevation; higher levels predict worse mortality
What tests should be ordered in suspected sepsis?
- CBC w/differential
- CMP
- CXR
- Urine and blood cultures
- PT/INR/PTT
How is sepsis treatment monitored?
With serial lactates
In general, when should antibiotics be administered in suspected sepsis?
As soon as possible. Some studies found differences if given within one hour, but other studies showed no difference if given anytime within five hours.
What does the three-hour sepsis bundle comprise?
- Lactate measurement
- Blood cultures drawn before antibiotic administration
- 30 ml/kg fluid bolus
- Antibiotics started
What does the six-hour sepsis bundle comprise?
- Reassess volume status after fluid administration
- Administer vasopressors for hypotension that does not respond to initial fluid administration
- Redraw lactate
“___________ should be considered the ECG of sepsis.” –CDEM on sepsis
Lactate
Clinical pearl: reassess patients for hypotension 30 - 60 minutes after administration of ____________.
antibiotics
