About this trial

This multicenter, prospective, randomized controlled trial will evaluate the efficacy and safety of bionic balloon-assisted delivery technology in nulliparous women planning vaginal delivery. Eligible participants will be randomly assigned in a 1:1 ratio to either the intervention group or the control group. Participants in the control group will receive routine labor management, while participants in the intervention group will receive bionic balloon-assisted delivery in addition to routine labor management after entering the active phase of labor.

The primary outcome is the duration of labor, including the first, second, and third stages of labor. Secondary outcomes include intrapartum cesarean conversion rate, intrapartum and postpartum complications, neonatal outcomes, postpartum pelvic floor dysfunction, postpartum depression, and maternal satisfaction. This study aims to determine whether bionic balloon-assisted delivery can shorten labor duration, reduce intrapartum cesarean conversion, and improve maternal and neonatal outcomes without increasing adverse events.

This trial does not accept healthy volunteers

Qualifiers

Age: 18-45 years;

Latent phase longer than 3 hours, cervical dilation greater than 4-5 cm (entry into the active phase), fetal head engagement, and no obvious cephalopelvic disproportion;

Voluntary participation in this study and signing of written informed consent.

Disqualifiers

Treatments tested in this trial

  • Bionic Balloon-assisted Delivery

    Device

    Bionic balloon-assisted delivery will be performed using the KCB-II automatic bionic balloon-assisted delivery device with a sterile latex balloon dilation handle. The balloon will be placed in the upper vagina near the fornix after artificial rupture of membranes and inflated according to the protocol to mechanically dilate the birth canal. Routine labor management will also be provided.

  • Routine Labor Management

    Procedure/Surgery

    Routine labor management includes standard monitoring and clinical management during vaginal delivery, artificial rupture of membranes when indicated, continued observation of labor progress and fetal status, operative vaginal delivery when necessary, and emergency cesarean section if indications such as arrest of labor, cephalopelvic disproportion, or abnormal fetal heart rate occur.

Treatment groups

300 Participants
are divided into 2 treatment groups
Group A: Balloon GroupExperimental treatment 1 intervention
Group B: Control GroupActive comparator 1 intervention

Trial outcomes

Primary outcomes

1

Duration of Labor

The duration of labor will be measured, including the first, second, and third stages of labor. The first stage of labor is defined as the period from the onset of labor to full cervical dilation; the second stage is defined as the period from full cervical dilation to delivery of the fetus; and the third stage is defined as the period from delivery of the fetus to delivery of the placenta.

Time frame
From onset of labor to delivery of the placenta.

Secondary outcomes

1

Intrapartum Cesarean Conversion Rate

The proportion of participants who undergo emergency cesarean section during trial of vaginal delivery due to indications such as arrest of labor, cephalopelvic disproportion, or abnormal fetal heart rate.

Time frame
During labor and delivery
2

Incidence of Intrapartum Fever

Percentage of participants with body temperature greater than or equal to 38 degrees Celsius after the onset of labor.

Time frame
From onset of labor to delivery
3

Incidence of Postpartum Hemorrhage

Percentage of participants with postpartum hemorrhage, defined as blood loss of at least 500 milliliters after vaginal delivery or at least 1000 milliliters after cesarean delivery within 24 hours after delivery.

Time frame
Within 24 hours after delivery
4

Incidence of Postpartum Infection

Percentage of participants with postpartum infection requiring antibiotic treatment after delivery.

Time frame
From 24 hours to 48 hours after delivery
