Septic shock: Hypotension Rx
Critical Care, Generic Clinical Sciences
Septic Shock = Vasidilatory Shock characterized by a low afterload state in which organ perfusion is impaired.
- Systemic venodilation from increased nitric oxide levels
- Decreased circulating intravascular volume from a diffuse capillary leak and the resulting transudation of fluid into tissues, producing a relative hypovolemia.
- Myocardial depression
There are many mechanisms for diffuse capillary leak from endothelial injury resulting from endotoxin, exotoxin, DIC, and many inflammatory factors.
