Sepsis Flashcards
Define sepsis
Life-threatening organ dysfunction due to a dysregulated host response to infection
What makes up a quick sofa score in veterinary
Mentation
Blood pressure
RR
Award one point
•if abnormal mentation/dull/obtunded/stuporous
• RR >22/min
• SBP <100mmhg
Which cytokines stimulate the HPA axis to increase CRH and ACTH secretion
IL-1, IL-6, TNF alpha
Sepsis in shock what type and why?
TypeB1 -underlying dz
Pathophysiology:
•Stimulation of skeletal muscle Na/K ATPase by catecholamines
•mitochondrial dysfunction including direct cytochrome inhibition
•increased hepatic lactate production
•reduced hepatic lactate extraction
•Impaired tissue oxygen extraction
•capillary shunting
•enhanced NO production
•altered neurohormonal control of endothelial smooth muscle
•reduced RBC flexibility
•increased leukocyte activation
•pyruvate dehydrogenase inhibition
