Final answer:
An infant is typically delivered via an emergency Caesarian section in the case of Abruptio Placenta to ensure the safety of both mother and baby. Post-delivery, the obstetrician must check to ensure the placenta is fully expelled to prevent postpartum hemorrhage.
Step-by-step explanation:
When an infant is to be delivered in the presence of Abruptio Placenta, a condition where the placental lining has separated from the uterus of the mother before delivery, the preferred method of delivery is often an emergency Caesarian section. This is because Abruptio Placenta can lead to significant hemorrhage and complications for both the mother and the fetus. During a Caesarian section, the obstetrician makes an incision on the mother's abdomen and uterus to deliver the baby safely.
It's crucial that the expelled placenta and fetal membranes are examined by the obstetrician to ensure they are intact to prevent postpartum hemorrhage. After delivery, uterine contractions aid in minimizing blood loss and begin the process of involution, which helps the uterus return to its pre-pregnancy size.
