There are other reasons for Caesarean Sections and it is sometimes caused by both the mother and the baby. Today, we would be examining fetomaternal reasons for Caesarean section which are cephalopelvic disproportion and obstructed labour. Lets learn more about these reasons-
• CEPHALOPELVIC DISPROPORTION (CPD) : This occurs when the presenting part of the baby (in this case the head) is larger than the pelvis of the mother. This is one of the commonest reasons for Caesarean section. It may arise from a very large baby or from the mother’s contracted pelvis. If CPD is not managed promptly, it worsens and becomes an obstructed labour.
• OBSTRUCTED LABOUR: This usually arises from a neglected CPD and it carries worse complications than CPD
PLACENTAL REASONS FOR CAESAREAN SECTION: Caesarean section may be done from problems arising from the placenta.
The two main placental reasons for Caesarean section are placenta preavia and placenta abruption. These two are the leading causes of ANTEPARTUM HEMORRHAGE (bleeding before onset of labour).
• PLACENTA PRAEVIA:
This occurs when the placenta is located at the lower part of the womb/entrance of the cervix. A normal placenta should be located at the upper part of the womb or in the body of the womb.
Placenta praevia causes abnormal bleeding which could be life threatening. There are about four types of placenta praevia.
Delivery in placenta praevia should be by Caesarean section.
• PLACENTA ABRUPTION:
This occurs when the placenta separates prematurely before the delivery of the baby Placenta normally should only separate after the baby has been born.
Placenta abruption when severe causes severe bleeding and rapidly kills the baby.
Natural delivery is preferred in placenta abruption. Caesarean section is only done if the baby is alive or the bleeding is difficult to control or for any other justifiable reason like CPD.
