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.
