Brief Summary

Obstetric practices now allow for prolonged second stage of labor to accomplish vaginal delivery. However, this practice may lead to either operative delivery (vacuum or forceps assisted delivery) or cesarean section with significant maternal/neonatal morbidity. Limited evidence suggests that dental support devices (DSD) may improve lead to shortened labor by allowing patients to push more effectively.

Detailed Description

In an effort to reduce the rate of cesarean section, obstetric practices now allow for prolonged second stage of labor to accomplish vaginal delivery. However, this practice is not without risks and may lead to either operative delivery (vacuum or forceps assisted delivery) or cesarean section with significant maternal/neonatal morbidity. Limited evidence suggests that dental support devices (DSD) may improve maternal valsalva and lead to a shortened second stage of labor by allowing them to push more effectively. Previous studies have been underpowered to find statistically significant results.

The Icahn School of Medicine at Mount Sinai has a unique and heterogeneous inner-city population of laboring mothers with marked rates of maternal obesity. The objective is to conduct a randomized controlled trial in which nulliparous patients are asked to use the LaboraideTM, a DSD designed for laboring women, while pushing with contractions in the second stage of labor.

Primary Outcome Measures
NameTimeMethod
Dilation Duration of Second Stage of Labor TimeUp to 3 hours

At the time of pushing in the second stage of labor, the time from full dilation to delivery during the second stage of labor in patients with vaginal delivery (spontaneous, vacuum, forceps included). Intention to treat analysis.

Delivery TimeAn average of 75 minutes

The time from initiation of pushing until delivery during the second stage of labor. Intention to treat analysis will be performed.
