Septic Shock Flashcards
1
Q
What is septic shock?
A
- Severe sepsis with hypotension, systolic <90mmHg, or >40mmHg reduction, despite adequate fluid resuscitation
- circulatory, cellular, and metabolic abnormalities associated with higher risk of mortality than sepsis alone
2
Q
What is sepsis?
A
Life threatening organ dysfunction caused by a dysregulated host response to infection
3
Q
What scoring system is used in patients with suspected infection and querying sepsis?
A
qSOFA score
- Resp rate >22/min
- Altered mental state GCS <15
- Systolic BP <100mmHg
4
Q
What is another name for the type of shock in septic shock?
A
Distributive shock
5
Q
What is the presentation of septic shock?
A
- Acute confusion
- Pyrexia / hypothermia
- Rigors
- Warm peripheries
- Bounding pulse
- Tachycardia >90bpm
- Tachypnoea >20breaths
- Hypotension <90 systolic or >40 drop
- WCC <4 or >12
6
Q
What are some red flag criteria for sepsis?
A
- Responds only to voice or pain/unresponsive
- Acute confusion
- Systolic <= 90 or >40 drop
- HR >130
- RR >25
- Needs oxygen to keep SpO2 >92%
- Non-blanching rash
- Not passed urine in last 18hours
- Lactate >=2mmol/l
- Recent chemo
7
Q
What is the management of septic shock?
A
- A-E assessment
2. BUFALO >Blood cultures >Urine output +U&Es (catheter) >Fluid challenge IV 10-15min >Antibiotics >Lactate (ABG) >Oxygen 15L
- Call critical outreach
8
Q
How are septic shock patients identified?
A
clinically identified by a vasopressor requirement to maintain a MAP ≥ 65mmHg and serum lactate >2mmol/L in the absence of hypovolemia
9
Q
What qSOFA score makes you worried?
A
2 or more
10
Q
Using the full SOFA score assessment what does a score of 2 mean in mortality risk?
A
10%
