Meaning of cephalopelvic disproportion or DCP

Cephalopelvic disproportion (PCD) is an obstetric disorder characterized by an insurmountable difference in size between the head of the fetus -and future baby- and the maternal birth canal. This means that either the head of the fetus is too large or the birth canal is too small for it to be delivered naturally through vaginal delivery.

It should be said that it is practically impossible to find a true PCD since most of them are due to unusual malformations of the pelvis or accidents that have caused the canal to narrow; on the contrary, most of the diagnoses of cephalopelvic disproportion are a poor positioning of the baby in antiphysiological postures or simply the result of little patience. There are few cases of women diagnosed with PCD. They have had to undergo a cesarean section and have subsequently been able to deliver babies even more significantly than the first through vaginal delivery.

Diagnosis of DCP

It is tough to diagnose cephalopelvic disproportion before labor begins. The tools we have give us an approximate but never exact idea of ​​what the baby will be like or how much the mother can dilate.

The ultrasound can estimate the size of the fetus; however, it cannot determine precisely what the fetal weight will be; therefore, it is not until the progress of labor is lengthened that the spread of the pelvis is insufficient to facilitate the exit of the baby and the correct functioning of the delivery and the medical treatment based on oxytocin is provided without success that cephalopelvic disproportion is diagnosed.

More unusual than it seems

According to studies in the United States, cephalopelvic disproportion is rare; it only occurs in 1 out of every 250 pregnancies. We must add that these DCPs are seldom accurate, but other complications that can occur in one part are grouped in this section. The American journal Journal of Public Health carried out a study in which they calculated that 65% of women diagnosed with cephalopelvic disproportion could have vaginal deliveries in subsequent pregnancies.
