Table of Contents Alerts. Of note, the two primary studies that these cases were drawn from showed slightly higher rates of operative vaginal delivery in the exposed groups and so the lower disproportlon of major perineal injury in the exposed groups must have been the product of some other factors. In addition, increasing rates of complications with repeat cesarean delivery have been associated with increasing number of previous cesarean deliveries [ 6 ].

Cephalopelvic disproportion and caesarean section.

The purpose of this is to help with education and create better conversations between patients and their healthcare providers. Accordingly, if lower rates of thick meconium passage at rupture of membranes is a marker for improved uteroplacental health, then the lower rates of thick meconium passage seen with the use of AMOR-IAPT represents a secondary benefit from delivery relatively early in the term period of labor.

A physical examination that measures pelvic size can often be the most accurate method for diagnosing CPD. A first-degree perineal tear was noted and repaired. She presented to the hospital on the evening prior to her delivery, and her fetus was noted to have a vertex presentation. She was completely dilated hours later. A simple table summarizing induction rates and birth outcome rates of exposed versus nonexposed nulliparous women is also presented.

If you have been diagnosed with CPD, it does not mean that you will have this problem in future deliveries. Due to concerns about the presence of multiple risk factors, and very significant amounts of each risk factor, she was admitted at 38 weeks 3 days gestation for induction of labor for impending CPD. She and her infant had unremarkable postpartum courses, and both were discharged to home in good condition on postpartum day 2. Cephaloppelvic 1 mile 5 miles 10 miles 15 miles 20 miles 30 miles 50 miles miles.


The patient continued to make slow progress. Her BMI at conception was The most common indication for primary cesarean delivery in nulliparous women is cephalopelvic disproportion CPD [ 8 ]. She pushed for about an hour and finally delivered an 8 pound 0 ounce infant over a small second degree perineal tear.

Her contraction frequency and strength began to fade in the late evening, and IV pitocin was started just before midnight. View at Google Scholar A. Although some mild variable decelerations were noted, the fetal heart rate demonstrated good general variability.

Following a review of this information, her final composite EDC was based on the crown-rump length measurement as this balanced the other two estimates. The prevention of primary cesarean delivery is especially important because the mode of delivery strongly impacts both the outcomes of the index pregnancy and the management and outcome of disproportiom pregnancies [ 67 ].

Ten hours later, the second dose of dinoprostone was removed, and IV pitocin was restarted. Fourth, the use of prostaglandins in the setting of preventive induction seems to be associated with a slight increase in the risk of postpartum uterine atony and higher postpartum blood loss.

An epidural catheter was placed for analgesia. Thereafter, a regular contraction pattern returned.

In addition, the presence of late decelerations during this labor suggests that, had her delivery been delayed another weeks, with associated placental aging, the likelihood of fetal intolerance to labor requiring a cesarean delivery would have also increased. With the fetal head on the perineum, several deep variable decelerations were noted. Labor and Birth Complications editor. Both the mother and her infant were discharged to home on the second postpartum day in good jouranl.

Cephalopelvic Disproportion (CPD): Causes and Diagnosis

Her one-hour gram glucola challenge was well within normal limits. Despite the fact that cesarean section deliveries are associated with increased risk of intra- and postpartum complications for both cepjalopelvic and babies [ 3 ], no strategy to prevent cesarean delivery has been developed. An NST was reactive, and she had normal vital signs.

She made steady progress with pushing, and her blood pressure remained within normal limits. Our cases illustrate that the successful induction of a nulliparous woman with an unfavorable cervix often requires the investment of significant time on the part of both the patient and her providers.


She was offered preventive induction of labor at 38 weeks 1 day gestation due to multiple risk factors for CPD and she accepted this offer.

Alternatively, the fetal position is changed. Over the next hour, her fetal heart tracing revealed mild intermittent late decelerations that were successfully treated with left lateral positioning and oxygen. She received a hour course of dinoprostone per vagina pledget followed by 8 hours of IV pitocin augmentation.

Cephalopelvic Disproportion (CPD)

However, this investment yields shorter overall hospital length of stay for mother and her baby due to reduced rates of cesarean delivery and NICU admission as well as reduction in levels of major adverse birth outcomes. Artificial rupture of membranes revealed clear amniotic fluid.

Labor management and clinical outcomes for each case are presented. Most risk factors for CPD cephaloplevic an established odds ratio that quantifies its impact on cesarean delivery risk.

These cases are followed by Table 1 that contains summary information concerning rates of labor induction, prostaglandin usage, and cesarean delivery in nulliparous women with risk factors jouenal CPD in the first two urban studies of AMOR-IPAT.

Because the mode of delivery of the first birth substantially impacts birth options in later pregnancies, the impact of AMOR-IPAT on nulliparous patients is particularly important.

We believe that, had she been allowed to gestate past 40 week gestation, she would have had a baby weighing eight pounds or more and would have probably required a cesarean delivery for second stage arrest of labor. Artificial rupture of membranes produced clear amniotic fluid.
