Lubricant gel to shorten the pushing phase of vaginal birth
Use of Lubricant Gel to Shorten the Second Stage of Labor During Vaginal Delivery: A Randomized Single-Blind Clinical Trial
This trial will try a single application of water-based obstetric lubricant during the second stage of labor to see if it shortens the pushing phase for term pregnant people planning a vaginal delivery.

What this trial studies
This single-blind, randomized, parallel-group trial will compare one 50 mL application of sterile water-based lubricant into the vaginal canal at the onset of the second stage of labor versus standard care without lubrication. A total of 160 participants at Hospital Escuela in Tegucigalpa will be randomized 1:1 and followed from admission through immediate postpartum discharge. The primary outcome is duration of the second stage of labor in minutes; secondary outcomes include perineal tears, episiotomy rates, need for instrumental delivery, maternal infections, and neonatal Apgar scores. Safety will be overseen by a DSMB and statistical analyses will use ANCOVA for the primary outcome with logistic regression or nonparametric tests for secondary outcomes as appropriate.
Who should consider this trial
Good fit: Adults 18–40 with term (37–41.6 weeks) singleton pregnancies in spontaneous labor with cephalic presentation who plan a vaginal delivery and provide informed consent.
Not a fit: People with multiple pregnancy, prior cesarean, high-risk obstetric conditions, active infection, prolonged rupture of membranes, or known allergy to lubricant components are excluded and unlikely to receive benefit.
Why it matters
Potential benefit: If effective, using lubricant during the second stage could shorten the pushing phase and reduce rates of perineal tears, episiotomy, or instrumental delivery.
How similar studies have performed: Routine clinical use and small prior trials have suggested lubrication may ease fetal passage, but high-quality randomized evidence is limited.
