Placental expulsion

Placental Expulsion

A human placenta being held after expulsion.

Placental expulsion is the process by which the placenta is delivered from the uterus following the birth of a baby. This stage is also known as the third stage of labor. The expulsion of the placenta is a critical part of the birthing process, as it marks the completion of childbirth.

Physiology

The placenta is an organ that develops in the uterus during pregnancy. It provides oxygen and nutrients to the growing fetus and removes waste products from the fetus's blood. After the baby is born, the placenta is no longer needed and must be expelled from the body.

The process of placental expulsion typically occurs within 5 to 30 minutes after the birth of the baby. It involves a series of uterine contractions that help detach the placenta from the uterine wall. These contractions are often less intense than those experienced during the second stage of labor.

Methods of Expulsion

There are two main methods of placental expulsion: active management and physiological management.

Active Management

Active management involves the administration of a uterotonic drug, such as oxytocin, immediately after the birth of the baby. This helps stimulate uterine contractions and reduces the risk of postpartum hemorrhage. The umbilical cord is clamped and cut, and gentle traction is applied to the cord to assist in delivering the placenta.

Physiological Management

Physiological management, also known as expectant management, allows the placenta to be expelled naturally without medical intervention. The mother is encouraged to breastfeed, which stimulates the release of oxytocin and promotes uterine contractions. The placenta is delivered spontaneously, usually within an hour of birth.

Complications

Complications during placental expulsion can include retained placenta, where the placenta does not detach from the uterine wall, and postpartum hemorrhage, which is excessive bleeding following childbirth. These conditions require medical intervention to prevent serious health risks to the mother.
