4 Clinical Trials for Various Conditions
The objective of our study is to evaluate the effect of CPAP on umbilical cord acid base status in morbidly obese women at the time of scheduled cesarean delivery. We hypothesize that neonates born to mothers wearing CPAP during the cesarean section will have a higher umbilical artery pH.

The aim of the study is to assess the efficacy and safety of an innovative two-hand (hand forceps) fetal head extraction technique during the transverse cesarean sections (LTCS) by comparing with the conventional one-hand technique used worldwide for centuries. The primary research question of the study is whether two-hand fetal head extraction technique results in quicker head delivery. The secondary research question is whether two-hand technique would cause increased incidence of extension of uterine incision as well as other adverse events while compared to conventional one-hand technique. Our hypothesis is that two-hand technique would speed up fetal head delivery without increasing the risk of extension of uterine incision as well as other adverse events, in the meantime, maternal discomfort will be significantly reduced since fundal pressure will not be required during the fetal head delivery.
Shortening the second stage of labor, the time spent pushing the baby out, is important for positive mother and infant's outcomes. Lack of progress of labor for any reason is the most common reason for cesarean section in women having their first baby and the second most common reason for cesarean section in women who have already had a baby. In 2014, a large study done across the United States showed increases in complications in both mother and infant when pushing was prolonged, including uterine infection, postpartum hemorrhage, more extensive vaginal tearing, shoulder dystocia, 5 minute Apgar score less than 4, infant admission to Neonatal Intensive Care Unit and neonatal infections. Therefore, the challenge is to consider alternative practices in order to maximize a mother's chance of a vaginal delivery and minimize these associated risks to both mother and baby. Mouth guards are used primarily in contact sports, and have been demonstrated to reduce or prevent injury to the teeth. Additionally, it has been proposed that wearing a mouth guard increases the strength of different muscle groups. A recent randomized controlled pilot study including women with their first pregnancy using a dental support device (DSD) during the second stage of labor evaluated the length of the second stage and outcomes. They found a significant decrease of 38% in the length of pushing time in the group that used a DSD. Additionally, there was a decreased rate of cesarean section in this group, however a p-value was not reported. This study only included 64 patients. A second, larger trial did not find a significant difference in pushing time, however the rate of interventions such as a vacuum or forceps-assisted vaginal delivery and cesarean section were much higher in the control group due to prolonged pushing. The results of the second study are contradictory in nature, yet the researchers do not provide hypotheses into why this may be. It is clear from the previously mentioned studies that further research is needed. Our hypothesis is that using such a device would help women to push more effectively during the second stage of labor thus shortening the time needed to push the baby out and increasing the rate of vaginal delivery. The purpose of this study is to determine whether wearing a mouth guard in the second stage of labor affects the length of the second stage of labor and improves mother \& infant outcomes.
