What happens to the spiral arteries during pre-e?

They are constricted which decreases blood flow

Why does the supine position cause decreased uteroplactenal blood

flow?

The aorta and vena cava get compressed (20 weeks)

Why does maternal hypotension happen after regional analgesia?

Blocks the sympathetic pathway

Pooling of blood in the lower extremities decreases blood flow back to

moms heart which decreases blood flow to the fetus

What percentage is uteroplacental blood flow decreased by during cxts?

60%

Explain the pathway for maternal- fetal exchange for fetal oxygenation

(basic)

Environment to lungs to heart to vasculature to uterus to placenta to

umbilical cord

Where is the least O2 blood in the fetus?

Limbs, kidneys, and descending aorta

Where is the most O2 blood in the fetus?

Umbilical vein and ductous venous

Connects the umbilical vein to the inferior vena cava, bypassing the liver

Shunt that allows most O2 blood to fetal heart

Ductus venosus

3 important shunts in fetal circulation

ductus venosus, foramen ovale, ductus arteriosus

connects the two atria in the fetal heart

Allows O2 blood to flow through the heart and directly to the brain

Foramen Ovale

a blood vessel in a fetus that bypasses pulmonary circulation by

connecting the pulmonary artery directly to the ascending aorta

Ductus Arteriosus

What is a normal blood volume for a fetus at term?

80-100 mL/kg

What happens if you stimulate the sympathetic nervous system?

Increased heart rate

What does the parasympathetic nervous system do?

Regulates the sympathetic

What happens when catecholamines (sympathetic) get released?

Increased heart rate

Why do pre-termers have increased heart rates?
