Labor, Second Stage clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Urinary Catheterization and Second Stage of Labor

Start date: July 2014
Phase: N/A
Study type: Interventional

- Labor is divided into three stages: the first stage is from labor onset until full dilation, second stage is from full dilation until delivery of the baby, and the third stage from the delivery of the baby until the delivery of the placenta - The mean duration of second stage in nulliparas as defined by the American college of obstetricians and gynecologists (ACOG) is 54 minutes - Epidural anesthesia is a known cause for prolongation of the second stage of labor. Prolonged second stage in nullipara women with epidural is defined as more than 3 hours, and more than 2 hours in those without epidural. - Although perinatal outcome is not compromised with a prolonged second stage , there is evidence that maternal morbidities such as perineal trauma, chorioamnionitis ,instrumental delivery and postpartum hemorrhage increase with prolonged second stage - Another effect of epidural anesthesia during labor is urinary retention and a need for catheterization. - Full bladder may behave as a tumor previa and interfere to fetal head descent in the birth canal, increasing by that the duration of the second stage. - This study aims to investigate the effect of intermittent versus continuous catheterization on the duration of the second stage of labor
