Sepsis - Schoenwald Flashcards
(46 cards)
What is bacteremia?
- -Bacteria in blood stream
- -Can be transient-tooth brushing
*overwhelming bacteremia results in + blood cultures, fever, chills
______ is a systemic response to infection that can cause organ failure and death in severe cases
sepsis
How do you quantify sepsis?
qSOFA
A sofa score greater than ____ reflects an overall mortality risk of 10% in a hospitalized patient
2
What are the three things measured in a qSOFA and what are the values?
- RR >/= 22
- GCS < 13
- SBP = 100
*Any 2 of 3 above likely to have a poor outcome
Lactate ______ (inc/dec) in sepsis
Increases
What happens in sepsis that causes disruption in homeostasis and leads to organ damage?
- Inflammation activated
- Coagulation activated
- Fibrinolysis suppressed (so inc clotting risk)
- Coagulopathy
________- is a key inhibitor or fibrinolysis in sepsis
PAI-1
What are 4 systemic results of sepsis?
- Decreased O2 delivery because of capillary damage
- Decreased CO (so body inc HR)
- Increased anaerobic metabolism
- DIC
What findings are elevated in DIC?
PT, PTT, Fibrin, D-dimer
What findings are decreased in DIC?
-Protein C, fibrinogen, platelet count
What lab findings are elevated in sepsis?
-Cr, ALT, AST, T bili, lactate, procalcitonin
What lab findings are decreased in sepsis?
-urine output, mental status, BP
What level of lactate is indicated in sepsis? what level is very worrisome?
> 4 and worrisome = 5
What is procalcitonin?
It is the earliest marker or a bacterial infection. It rises quickly with bacteremia and decreases after initiation of abx
- –Used to know when to stop abx basically
- Not helpful in viral causes that turn into sepsis
What level of procalcitonin is suggestive of sepsis?
Values > 2.0
What is the #1 cause for severe sepsis?
Community acquired pneumonia (Gram + strep)
What three demographics are at greater risk for sepsis?
- Older age 65 +
- Underlying comorbidity
- higher body weight
What symptoms does the SEPSIS acronym stand for?
S- shivering, fever, very cold E- extreme pain P- pale or mottled skin S- sleepy, confused I- I feel like I might die S- SOB
What is the SIRS criteria?
Systemic Inflammatory Response System >/= two
- Temp >100.4 or <96.8
- HR > 90
- Tachypnea RR > 20 or PaCO2 <32
- WBC > 12,000
What is the mc cause of severe sepsis?
Pneumonia (CAP)
What does the Screening for Severe Sepsis for patients include?
Infection + SIRS + Acute Organ Dysfxn
What is the mc bacteria in neonatal sepsis?
GBS & E. coli
*really important to check b=mom for this before delivery (can treat with PCN)
What is the MC cause of sepsis in an IV drug user?
Staph aureus and MRSA
