    Study Notes

    Labor and Birth

    • Uterine contractions initially occur when the mother's body prepares for labor, usually around the 37th week of gestation.
    • The period of transition, which is the most intense part of labor, occurs when contractions reach their greatest intensity.
    • Oxytocin is released during labor when the baby's head presses against the cervix and stimulates the release of this hormone.

    Stages of Labor

    • During the second stage of labor, the baby's head moves through the birth canal.
    • The third stage of labor is when the placenta is expelled from the uterus.

    Episiotomy and Interventions

    • An episiotomy is a surgical incision to widen the vaginal opening during labor, allowing for a smoother and less traumatic delivery.

    Birth Attendants and Settings

    • In North America, around 99% of births are attended by skilled health personnel.
    • In the least developed countries, only around 45% of births have skilled health personnel in attendance.
