How does cord drainage during the third stage of labor affect blood loss?

The answer indicating that cord drainage during the third stage of labor reduces the duration of the third stage is correct because this practice can facilitate the delivery of the placenta. Cord drainage involves cutting the umbilical cord and allowing blood to flow from the placenta to the neonate, which can assist in mobilizing the placenta and make its expulsion more efficient. This can lead to a shorter duration of the third stage of labor, as less time is taken for the placenta to separate and be delivered after the baby has been born.

In many cases, a shorter third stage can also help minimize maternal risks associated with prolonged labor, such as increased blood loss or the need for interventions. The physiological processes behind this involve the reduction in blood volume in the placenta when drainage occurs, which can help with uterine contractions that assist in placental detachment. Thus, this approach supports more effective and rapid expulsion of the placenta following the birth.
