Final answer:
External uterine massage is primarily used post-delivery to facilitate placenta expulsion and to control postpartum hemorrhage by promoting uterine contractions. It's a part of the third stage of childbirth and is used when contractions are inadequate or bleeding is excessive.
Step-by-step explanation:
Conditions for External Uterine Massage
Under the Emergency Childbirth Medical Directive, an external uterine massage may be indicated after the birth of the baby to facilitate the expulsion of the placenta and to control potential postpartum hemorrhage. As part of the third stage of childbirth, the massage is performed to encourage the uterus to contract and to clamp down on any bleeding vessels post delivery. It is important in cases where uterine contractions are insufficient or where the bleeding is heavier than normal.
The stages of childbirth include cervical dilation, the expulsion of the newborn, and the afterbirth, which involves delivering the placenta. External uterine massage may become necessary if the uterus does not contract effectively during the third stage. Pitocin, a synthetic form of oxytocin, may also be administered to help stimulate uterine contractions and prevent or treat postpartum hemorrhage.
