    STOPOXY

    NCT03991091

    17 Jan 2020 to 25 Apr 2022

Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

The purpose of this study is to measure the impact of a discontinuous administration of oxytocin during the active phase of the 1st stage of labor on the neonatal morbidity rate. The investigators hypothesize that discontinuation of oxytocin in the active phase of labor (from 6 cm) in women who received oxytocin in the latent phase or for an induction (before 4 cm of dilation) could reduce neonatal morbidity.

Interventions

  • discontinuation of oxytocin administrationDrug
  • continuation of oxytocin administrationDrug

Arms2

  • Experimental

    discontinuation of oxytocin administration

    Discontinuation of oxytocin administration at the beginning of the active phase of the 1st stage of labor, i.e. oxytocin infusion will be stopped beyond a cervical dilatation of 6cm

  • Active comparator

    continuation of oxytocin administration

    Standard care in France, i.e. when oxytocin is started during the latent phase of the 1st stage, administration of oxytocin is continued during the active 1st stage and during the 2nd stage if the fetal heart rate is reassuring.

Primary outcomes1

Outcomes the sponsor listed as primary.

  1. neonatal morbidity composite measure

    Time frame · At birth

    Registry description

    Neonatal morbidity will be assessed using a composite variable defined by: an umbilical arterial pH at birth \<7.10 and/or a base excess \>10mmol/L and/or umbilical arterial lactates\>7 mmol/L and/or a 5 minutes Apgar score \<7 and/or admission in neonatal intensive care unit (NICU). This composite outcome is based on pertinent and previously published thresholds to assess neonatal acidosis\[16\]

Secondary outcomes(20)
  1. umbilical cord pH<7.20

    Time frame · At birth

    Registry description

    umbilical arterial cord pH at birth less than 7.20

  2. umbilical cord pH<7.10

    Time frame · At birth

    Registry description

    umbilical arterial cord pH at birth less than 7.10

  3. umbilical cord pH<7.00

    Time frame · At birth

    Registry description

    umbilical arterial cord pH at birth less than 7.00

  4. Need for hypothermia

    Time frame · 2 hours postpartum

    Registry description

    Time frame · 0-48hours

    Registry description

    cesarean rate

  9. mode of delivery

    Time frame · 0-48hours

    Registry description

    cesarean rate for abnormal fetal heart rate

  10. mode of delivery

    Time frame · 0-48hours

    Registry description

  12. labor duration

    Time frame · 0-48hours

    Registry description

    labor duration (active 1st stage, passive and active 2nd stage)

  13. uterine hyper-stimulation

    Time frame · 0-48hours

    Registry description

    uterine hyper-stimulation, defined by periods with more than 5 uterine contractions in 10 minutes during labor

  14. fetal scalp blood testing

    Time frame · 0-48hours

    Registry description

    need for fetal scalp blood testing during labor

  15. fetal occipito-posterior position

    Time frame · 0-48hours

    Registry description

    fetal occipito-posterior position

  16. maternal hyperthermia

    Time frame · 0-48hours

    Registry description

    maternal fever during labor, defined by maternal temperature \>38°C

  17. postpartum hemorrhage

    Time frame · 0-48hours

    Registry description

    post-partum hemorrhage, defined by an estimated blood loss \>500mL

  18. The post-partum women's satisfaction

    Time frame · 0 5 day

    Registry description

    women's satisfaction is recorded using the "labor agentry scale". Scores on the Labor Agentry Scale range from 29 to 203, with higher scores indicating greater perceived control during childbirth.

  19. The post-partum women's satisfaction: labor agentry scale

    Time frame · at 2 months postpartum in a survey

    Registry description

    women's satisfaction is recorded using the "labor agentry scale"\[18\]

  20. The post-partum women's satisfaction

    Time frame · at 2 months postpartum in a survey

    Registry description

    Edinburgh Postnatal Depression Scale. Scores on the Edinburgh Postnatal Depression Scale rabge from 0 to 30, with higher score indicating mental health issues.
