Study summary

Perineal trauma during vaginal delivery is very common, especially in countries with a high prevalence of episiotomy. Perineal traumas can range from tears limited to the skin, subcutaneous and vaginal mucosa to severe tears involving the anal sphincter and rectal mucosa. Perineal trauma is associated with short-term morbidities such as bleeding, infection, pain, edema. Besides, it may cause long-term morbidities such as urinary incontinence, fecal incontinence, dyspareunia, a decrease in quality of life, a need for surgery, and psychosocial problems. Moreover, it is associated with an increase in national healthcare costs and malpractice cases. For these reasons, some measures to reduce the frequency of perineal trauma have been discussed for many years. Pushing techniques applied in the second stage of labor and manual perineum protection techniques applied during fetal expulsion are among these. Current data are insufficient to make definitive recommendations. In this study, it was aimed to compare different pushing and perineal protection techniques in the second stage of labor.

Interventions

  • ProcedureCoached pushing and Finnish manual perineal protection

    Pushing technique: Rest will be encouraged between uterine contractions. With the onset of uterine contraction, women will be instructed to breathe normally. They will then be instructed to take a deep breath and hold (closed-glottis), and push down strongly for as long as possible (up to 10 seconds). After pushing effort, normal breathing will be encouraged, then the same pushing instruction will be repeated again. Fetal expulsion: The expulsion rate of the fetal head will be controlled by light pressure applied on the fetal occiput. Simultaneously, the thumb and index finger of the dominant hand will be used to support the perineum, while the bent middle finger will grasp the baby's chin. Once a good grip is achieved, the investigator slowly assists in the expulsion of the fetal head from the vaginal introitus. When most of the fetal head is out, the perineal ring will be pushed under the baby's chin.

  • ProcedureUncoached pushing and Hands-poised perineal protection

    Women will not be given any instructions regarding straining and breathing, and will be allowed to follow their own pushing impulses. During the expulsion of the fetal head, the hands of the researcher will be kept in the air and ready for the intervention, but pressure will not be applied to the fetal head or perineum unless necessary (fetal hypoxic appearance, strain detection with a risk of spontaneous laceration towards the anus in the midline).

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2021 to primary completion in May 2023, 25 months.

Of 27 interventional studies with no phase under Obstetric Labor Complications, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 51. This study's 25 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 24, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
