Can Have A Normal Delivery If The Body Of The Fetus Exceeds The Normal Size?
I want to ask, can a pregnant woman whose height is below 150 cm not have a normal birth? Because the pelvis is not too broad, aka narrow. I am now 31 weeks pregnant and the fetus has exceeded normal body weight, so I have to diet. And what is the normal size of a baby’s head? Explanation please
Good morning, thanks for the question
In such cases the obstacle to normal delivery is the risk of cephalopelvic disproportion
(CPD) because mothers with short posture as a risk factor. CPD is a match between the size of the baby's head with the size of the mother's pelvis so that a normal delivery will be difficult even if assisted with medication.
Normal childbirth will be at long risk until fetal distress can occur. If labor does not show progress then immediate surgical action is necessary. However, it is very difficult to be able to diagnose CPD before women enter labor because it is difficult to estimate how the baby's head can adjust the size of the mother's pelvis. Baby's head bones can overlap to adjust the size of the mother's pelvis, and the mother's pelvic space can also be widened during labor so that some cases of normal labor can occur.
To estimate the size of a woman's pelvis can be with several methods, namely:
1. Manual pelvic examination through vaginal examination
2. Ultrasound examination
Risk factors for CPD events include:
1. Mother with obesity
2. Previous caesarean birth history
3. Excessive amniotic fluid
4. Not the first pregnancy
5. Mother's age> 35 years
6. Mother's short stature
7. Transverse diagonal size on examination within <9.5 cm
8. Postmatur pregnancy
9. Abnormal fetal position
10. Abnormal pelvic bone shape
11. Big baby
In your case, normal delivery is still possible until the time of delivery. However, when the time of delivery turned out to be very minimal progress even with drugs, it must be immediately considered by caesarean section to prevent complications in the mother and fetus. Regarding the size of the baby's head, the normal size at delivery is around 35 cm.
That's all, hope you can help
