26- Sepsis Flashcards
sepsis is due to
disregulated inflammatory response to infection
define septic shock
is sepsis that has a circulatory, cellular and metabolic abnormalities associated greater risk of mortality than sepsis alone
critera for sepsis
despite adequate fluid resuscitation, require vasopressors to maintain a mean arterial pressure >65 mmHg and have a lactate of >2 mmol
T/F about 80% of hospital treated sepsis arise in the community
T
most common site of infection that leads to sepsis is
- lung (64%)
- abdomen (20%)
- bloodstream (15%)
- renal and genitourinary (14%)
T/F thereis almost equal prevalence of gram pos and gram nag bacterial infections in pts with sepsis
T
- gram pos: s aureau
- gram neg: Pseudomanas, E coli
SOFA score
sequential organ failure assessment
- used in ICE to predict in hospital mortality in critical pts
- PaO2/FIO2; coagulation platelets; bilirubin; hypotension; GCS; creatinine/urine output
q SOFA is
THIS IS NOT FOR RULING OUT PTS PTS based on 3 things (high risk if 2 criteria) - alteration in mental status - systolic blood pressure <100 mmHg - respiratory rate >22 bpm
mx of sepsis
1 hour bundle
- initial fluid resuscitation
- antibiotic tx
- source control
- vasoactive
poor prognostic factors for sepsis
- inability to mount a fever
- leukopenia
- > 40 age
- comorbidities (AIDS, hepatic failure, cirrhosis, cancer, alcohol dependance, immunosuppression)
- non urinary infection
- nosocomial source of infection
- late/wrong antibiotic coverage
serum lactate level in septic shock
> =4mmol/L
