Sepsis Flashcards
SOFA?
Sequential (Sepsis-related) Organ Failure Assessment score
sepsis- acute change >2
qSOFA
Quick SOFA
- RR >22
- altered mentation
- BP <100mmHg
Septic shock is?
sepsis + hypotension
Sepsis 6?
Give 3 and take 3
give:
1. O2 (aim for 94-98% sats)
2. IV A/Bs
3. Fluid challenge
take:
- Blood Lactate - marker of generalised hypo perfusion (severe sepsis)
- Measure Urine output (renal dysfunction)
- Blood culture
Physiology of sepsis
- Bacterial invasion - ENDOTOXIN: binds to macrophage
- release of CYTOKINES
- initial increase in PRO-inflammatory mediators: COMPLEMENT activation, vasodilation (septic shock)
- compensatory ANTI-inflammatory mediators: inhibit TNF alpha, COAGULATION system: situation in immunoparalysis - uncontrolled infection + multi organ failure
PC of sepsis
o CNS = altered consciousness, confusion, psychosis
o Increased RR, Pa02 <70, Sats <90%
o Jaundice, decreased albumin, decreased platelets and increased D-dimer
o Tachycardic, arterial hypotension
o Oliguria, anuria, increased creatinine
o High lactate
o Skin mottling + reduced cap perfusion
bacteraemia + septicaemia - difference?
bacteraemia - presence of bacteria in the blood stream.
septicaemia: presence of bacteria in blood stream + clinical manifestations = signs + symptoms
SIRS
Sepsis
severe sepsis
septic shock
- systemic inflammatory response syndrome
- Sepsis: SIRS + documented infection
- Severe sepsis: End organ damage, high lactate
Septic Shock: sepsis + hypotension/hypoperfusion
CURB65 SCORE?
assessment of mortality (point for each)
- tachypnoeic >22RR
- hypotensive <100mmHg
- High blood nitrogen
- > 65yo
- Confused
most common causes of sepsis
gram (+)
- E.coli
- Strep pyogenes
- Pseudonomas aeruginosa
- Klebsiella
