Fetal head articulation is delayed after labor

Introduction Clinical manifestations of persistent posterior occipital and occipital transverse position. After the delivery, the fetal head is connected late and the flexion is poor. Because the posterior part of the occipital position is not easy to close to the lower part of the uterus and the internal cervix, it often leads to poor coordination of uterine contractions and slow expansion of the cervix. Because the occipital bone continues to be located in the back of the pelvis and compresses the rectum, the mother feels anal bulge and defecation, causing the cervix to not be fully opened. Abnormal fetal position leads to secondary uterine atony, which leads to prolonged labor, often requires surgical midwifery, is prone to soft birth canal injury, and increases the chance of postpartum hemorrhage and infection. If the fetal head compresses the soft birth canal for a long time, it can cause ischemic necrosis and fall off, forming a genital wart.

Cause

After the delivery, the fetal head is connected late and the flexion is poor. Because the posterior part of the occipital position is not easy to close to the lower part of the uterus and the internal cervix, it often leads to poor coordination of uterine contractions and slow expansion of the cervix. Because the occipital bone continues to be located in the back of the pelvis and compresses the rectum, the mother feels anal bulge and defecation, causing the cervix to not be fully opened.

Impact on the mother: Abnormal fetal position leads to secondary uterine weakness, prolonged labor, often requires surgical midwifery, prone to soft birth canal injury, and increased chances of postpartum hemorrhage and infection. If the fetal head compresses the soft birth canal for a long time, it can cause ischemic necrosis and fall off, forming a genital wart.

Impact on the fetus: Due to the prolongation of the second stage of labor and increased chances of surgical midwifery, fetal distress and neonatal asphyxia are often caused, resulting in increased perinatal mortality.

Differential diagnosis

Combined with clinical symptoms and signs, the posterior occipital position is generally not difficult to distinguish from other dystocia types. If necessary, combined with B-ultrasound examination, using ultrasound images to understand the position of the fetal face and occipital position, the diagnosis can be confirmed, timely treatment, no need for repeated anal examination And vaginal examination. Strive to find the back of the pillow in the early stage of labor, so that it can be treated in time to avoid prolonged labor.

Other auxiliary inspections:

1. Ultrasound imaging examination.

2. X-ray diagnosis.

The postpartum fetal head is connected late and the following symptoms are differentially diagnosed:

1. Abnormal labor with the anterior position of the pillow.

2. The abnormality of labor is accompanied by high straight position of the fetal head.
