50
Q

How does the pathophysiology of preeclampsia differ from gestational hypertension?

A

Arteriolar vasospasm diminishes diameter of blood vessels, which impedes blood flow to all organs (including placenta) and increases BP. Function in placenta, kidneys, liver, and brain depressed as much as 40%-60%.

51
Q

What can these vasospasms lead to and what is the cure?

A

Can lead to HELLP syndrome and delivery is the cure.

A

HELLP syndrome can lead to coagulopathy, which is any blood clotting problem.

A

Placental abruption, renal failure, pulmonary edema, ruptured liver hematoma, DIC, Fetal/maternal death.

55
Q

What can be done for severe preeclampsia?

A

Hospital care, MSo4, control BP, bed rest in lateral recumbent, high protein/low salt diet.
