Study Notes

Caput Succedaneum

Swelling of the scalp at the presenting part of the head

Cardinal Movements of Labor

Position changes to keep the smallest diameter of the fetal head (in cephalic presentations) always presenting to the smallest diameter of the birth canal. This includes:
- Descent
- Flexion
- Internal Rotation
- Extension
- External Rotation
- Expulsion

Amnioinfusion

Enlarging the amount of amniotic fluid by administration of normal saline or lactated Ringer’s solution intravaginally into the uterus

Afterpains

Intermittent cramping due to uterine contraction during involution in the postpartum period.

Amniotic Cavity

The space in the developing conceptus from which the ectodermal cells develop.

Amniotic Fluid Embolism

A condition in which amniotic fluid is forced into maternal circulation and travels to the lungs as small emboli.

Amniotic Membrane

The innermost membrane surrounding the fetus; it secretes amniotic fluid.
