Which of the following is a cause of vasodilatory shock?
|B||Carbon monoxide poisoning|
|D||Severe muscle injury with rhabdomyolysis|
a. In the peripheral circulation, profound vasoconstriction is the typical physiological response to arterial pressure that is insufficient for tissue perfusion, usually causing cardiogenic or haemorrhagic shock.
b. In vasodilatory shock, hypotension results from failure of vascular smooth muscle to constrict appropriately. The most frequently encountered form of vasodilatory shock is septic shock.
c. Other causes of vasodilatory shock include hypoxic lactic acidosis, carbon monoxide poisoning, decompensated and irreversible haemorrhagic shock, terminal cardiogenic shock and post cardiotomy shock.
