NCT05461950

Brief Summary

This is a feasibility study with historical control designed to evaluate whether delivery of the placenta prior to umbilical cord clamping at caesarean sections is a feasible, safe and acceptable way of facilitating intact-cord stabilisation of preterm and term newborn infants.

Outcome Measures

Primary Outcomes (2)

  • Intervention fidelity (cohort 1)

    Extra-uterine placental transfusion + physiology-based cord clamping applied (for vigorous infants), measured as proportion of completed checklists. Registered by staff, using checklists in the operating room.

    First 10 minutes after delivery

  • Intervention fidelity (cohort 2)

    Extra-uterine placental transfusion + intact-cord stabilisation + physiology-based cord clamping applied (for infants needing any respiratory support), measured as proportion of completed checklists. Registered by staff, using checklists in the operating room.

    First 10 minutes after delivery

Secondary Outcomes (14)

  • Dry-electrode ECG attached (cohort 1+2)

    Within 10 seconds after birth

  • First cry or breathing effort (cohort 1+2)

    Within 10 minutes after birth

  • Heart rate (cohort 1+2)

    First 10 -15 minutes after birth

  • Umbilical cord blood samples (cohort 1+2)

    Within 40-60 seconds after birth

  • Apgar score (cohort 1+2)

    At 1 minute after birth

  • +9 more secondary outcomes

Other Outcomes (8)

  • Post-cesarean infection (all cohorts)

    Within14 days after surgery (cesarean section)

  • Abnormal blood loss (all cohorts)

    45 minutes from incision time

  • Pre-operative maternal Hemoglobin

    Within 48 hours before cesarean section

  • +5 more other outcomes

Study Arms (3)

Self-breathing infants

Vigorous infants with spontaneous onset of respiration within one minute after delivery by cesarean section, receiving extra-uterine placental transfusion and physiology-based cord clamping

Procedure: Extrauterine placental transfusion and physiology-based umbilical cord clamping

Infants with respiratory support

Infants with no or poor spontaneous onset of respiration after delivery by cesarean section, receiving extra-uterine placental transfusion, intact-cord stabilisation (any respiratory support) and physiology-based cord clamping after transfer to resuscitation table

Procedure: Extrauterine placental transfusion, intact cord stabilisation and physiology-based umbilical cord clamping

Historical control group

Infants delivered by cesarean section in a time period when delayed cord clamping after 1-3 minutes was default procedure. Less-than-vigorous infants needing respiratory support or full resuscitation had their umbilical cords cut early (within 30 seconds)

Procedure: Delayed umbilical cord clamping

Interventions

Placenta is delivered prior to umbilical cord clamping to facilitate placental transfusion. Infant and placenta are transferred to a warmer in an adjacent room, the umbilical cord is clamped and cut when the cord is white, pulsations have ceased and the infants is breathing regularly (within 10 minutes after delivery)

Self-breathing infants

Placenta is delivered prior to umbilical cord clamping to facilitate placental transfusion. Infant and placenta are transferred to a warmer in an adjacent room and necessary respiratory support is initiated (CPAP or PPV) by a neonatal team. The umbilical cord is clamped and cut when the cord is white, pulsations have ceased and the infant is breathing regularly with or without support (at maximum 10 minutes after delivery)

Infants with respiratory support

Umbilical cord is clamped and cut minimum 60 seconds after delivery to facilitate placental transfusion. Placenta is delivered after cord clamping. Infants needing respiratory support or other stabilisation are transferred to a warmer in the adjacent room where a neonatal team is waiting.

Study Population

Women planning to give birth at Clinic Ålesund are candidates for enrolment in this clinical study. Pregnant women will be invited to participate when called for second trimester routine ultrasound scan. They will be asked for preliminary consent in the event of intrapartum or planned cesarean section and fullfilment of inclusion cirteria. Women having ultrasound scans done elsewhere, who are later referred to Clinic Ålesund, may be invited to participate after admission, but will not be approached for consent if delivery is imminent. Both parents (if applicable) must consent on behalf of their infant

You may qualify if:

  • live infants (singletons or dichorionic twins) born in gestational week 32+0 to 42+0
  • delivered by CS in regional anaesthesia
  • immediate care may be planned with involved personnel prior to delivery
  • informed maternal consent is obtained (parental consent on behalf of the unborn child).

You may not qualify if:

  • twins, triplets
  • significant congenital malformations
  • placenta complications with high risk of abnormal maternal blood loss
  • severe fetal distress requiring cesarean section in general anaesthesia (crash CS)
  • participation in any other clinical study within the last month
  • not sufficient time for preparations or collection of maternal/parental consent
  • mother does not comprehend Norwegian or English
