Study summary

Despite the fact that a link between cholesterol and the myometrium has been clearly established, no study investigating aspects of cholesterol metabolism and uterine dystocia currently exists. This study is a pilot study whose aim is to test the hypothesis that an association between uterine dystocia and single-nucleotide polymorphisms (SNPs) in the genes coding for the LXRs.

Study population

The study population represents women undergoing a difficult, stagnating labor due to either physical or uterine dystocia.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients undergoing C-section for a dystocia: 2 to 3 hours of stagnation in labor progress are observed (ie no increasing dilation, and uterine contractions less that 3-5 per 10 minutes) in spite of measures taken to overcome dystocia (oxytocin injection and artificial breaking of waters)
  • the child is alive
  • the child does not have apriori known malformations that could interfere with a vaginal birth
  • foetus in cephalic position
  • full term pregnancy (>= 37 weeks of amenorrhea)
  • single birth
  • patient has signed consent
  • patient is affiliated with a social security system

Exclusion criteria

Exclusion Criteria:

  • vaginal birth
  • programmed C-section
  • C-section is chosen because the fetus has a cardia rhythm problem, and there is no stagnation in the labor process
  • multiple pregnancy
  • the child is in a breech position
  • premature birth (\<37 weeks amenorrhea)
  • in utero fetal death
  • fetal malformation known before birth that could interfere with a vaginal birth
  • non french-speaking patient (impossible to correctly inform the patient)
  • patient under guardianship

  • Group 2

    These patients have uterine dystocia

    Biological: Whole blood sampling

Interventions

  • BiologicalWhole blood sampling

    Whole blood sampling for SNP polymorphism analysis
