SHOCK
-
Causes of shock
-
-
Distributive shock (septic, anaphylactic and neurogenic shock)
-
-
Pathophysiology of Shock
Stimulates baroreceptors in the aortic arch and carotid sinus. Increased sympathetic stimulation --> noradrenaline an d adrenaline are released . Causes vasoconstriction. Allows BP maintenance
-

-
-
Overall Shock Diagnosis:
-
-
-
U&E, LFT and FBC (exclude anaemia)
-
What is Shock?
-
HOW CAN WE RECOGNISE IT?
SKIN is pale, sweaty and vasoconstricted
-
-
-
Confusion, weakness, collapse and coma
Shock is a condition that is characterised by acute circulatory failure with inadequate or inappropriately distributed tissue perfusion (lack of glucose or oxygen) for aerobic cellular respiration. It is generalized as the inability for the heart to be able to pump
Effects of Shock
-
Capillary refill time (CRT). This is not good if it takes more than 3s for it turn pink after 5s of compression. EARLIEST & MOST ACCURATE SIGN OF SHOCK
Prolonged hypotension can lead to life-threatening organ failure after recovery from the acute event
Hypovolemic Shock
Loss of fluid: in dehydration, burns or pancreatitis
Blood loss due to an acute GI bleed, trauma, post operative or a splenic rupture
-
-
-
Septic Shock
-
-
Happens when sepsis is complicated by persistent hypotension and unresponsive to fluid resuscitation
-
Organs at risk
-
Brain - confusion , irritability and coma
-
-
Treatment
Breathing- cure any congestive problems. Prevent congestive cardiac failure, bronchospasm or tension pneumothorax
