Q

what happens in acute liver failure?

A

hepatocellular dysfunction that develops rapidly, blood flow through the liver is disrupted, and cerebral edema and intracranial hypertension occur

159
Q

In acute liver failure, hepatocellular dysfunction that develops rapidly causes liver to stop synthesizing plasma proteins. What happens due to this?

A

capillary oncotic pressure decreases, fluids shift from intravascular to interstitial space, aldosterone is not inactivated, and the high levels of aldosterone cause kidneys to retain sodium and water and excrete potassium

Q

In acute liver failure, cerebral edema and intracranial hypertension occur because neurotoxins are not cleared from the GI system. How does it happen?

A

they accumulate in the systemic circulation, the brain swells and disruption of blood-brain barrier leads to intracranial HTN and irreversible neurologic damage
