Sepsis Flashcards
SIRS Criteria (need 2 or more)
- Temperature > 38 C or < 36 C
- HR > 90 bpm
- RR > 20 bpm or PaCO2 < 32 mmHg
- WBC count > 12,000/cu mm, < 4000/cu mm, or >10% band forms
Define SIRS
The systemic inflammatory response to a variety of severe clinical insults
Define sepsis
The presence of SIRS along with clinical or microbiologic evidence of an infection
Define septic shock
Sepsis induced hypotension despite adequate fluid resuscitation, along with perfusion abnormalities (lactic acidosis, oliguria, acutely altered LOC)
Sepsis is…
- Common
- Increasing in incidence
- Deadly
Outline the patho of sepsis
- Infection
- Inflammatory mediators (3 amigos)
- Vasodilation and endothelial damage
- Hypotension, microvascular plugging, vasoconstriction, edema
- Inappropriate distribution of microvascular blood flow
- Ischemia
- Cell death
- Organ dysfunction
Top 3 organisms isolated in septic shock (from class)
- E. coli
- S. aureus
- S. pneumoniae
Clinical features of sepsis
- Fever
- Confusion
- Increased WBC count
- Tachypnea
- Tachycardia
- Hypotension
- Decreased vascular tone
- Organ dysfunction
Clinical signs of septic shock
- Myocardial depression
- Altered vasculature
- Altered organ perfusion
- Imbalance of 02 delivery and consumption
- Lactic acidosis
Management of sepsis
- Fluid resuscitation
- Cultures prior to giving antibiotics
- Early targeted antibiotics and source control
- Give vasopressors/inotropes
What is the most common cause of sepsis, Gram +ve or Gram -ve organisms?
Gram +ve
Sepsis management points
- Failure to implement source control = higher mortality
- Using an ineffective antibiotic = higher mortality
- Delaying antibiotic administration = higher mortality
- Hit it early and hit it hard
Preventing complications of sepsis
- Prophylaxis for DVT to prevent a possible PE
- Stress ulcer prophylaxis (i.e. PPI)
- Elevate head to 45 degrees to prevent HAP
- Interrupt sedation daily to facilitate extubation
