Study Notes
Labor and Delivery
- Intrapartum period: The time from onset of labor to birth of the baby.
- Labor (Parturition) Delivery: The process by which the fetus, placenta, and membranes are expelled from the uterus.
Theories of Labor Onset
- Uterine Stretch Theory: Labor begins when the uterus is stretched by the growing fetus, stimulating contractions.
- Oxytocin Stimulation Theory: The posterior pituitary gland secretes oxytocin in response to fetal movement and cervical dilatation, stimulating uterine contractions.
- Progesterone Deprivation Theory: Uterine contractions are caused by a drop in progesterone levels, allowing estrogen to stimulate contractions.
