Study summary

The aim of this study is to compare perinatal survival in patients presenting with early spontaneous PPROM and persistent oligohydramnios, managed either conservatively or with serial amnioinfusions.

Read the detailed description

Early spontaneous Preterm Premature Rupture of Membranes (PPROM) is associated with high perinatal mortality. Due to pulmonary hypoplasia and preterm delivery, mortality exceeds 60% when PPROM occurs prior to 24 weeks. When oligohydramnios persists, it may raise to 90%. Morbidity in survivors is also significant. In uncontrolled series, serial amnioinfusions, which have acceptable invasiveness and are of limited complexity, mortality was reduced to 60%.

We propose an open, multicenter randomized trial comparing perinatal survival in patients presenting with early spontaneous PPROM and persistent oligohydramnios, managed either conservatively or with serial amnioinfusions. Inclusion criteria: Single pregnancy, early spontaneous PPROM \< 24.3 weeks, oligohydramnios (deepest vertical pocket \< 2 cm) for at least 4 days and no longer than 15 days at enrolment. The study is open and will be run through a dedicated password protected web site, and with a minimal number of outcome measures. Primary outcome: Survival till discharge from the NICU. Secondary outcomes: Latency time from PPROM to delivery, gestational age at birth, indication for delivery, number of days of ventilatory support, serious neurologic morbidity, neonatal sepsis prevalence, need for oxygen at 36 weeks post-conception.

In context

Oligohydramnios

25 studies on the registry are indexed under Oligohydramnios; 5 are open to participants now.

This study's planned enrollment of 82 is close to the median of 91 across 16 interventional studies indexed under Oligohydramnios.

Inclusion criteria

  1. Patients above 18 years, who are able to consent, with
  2. Singleton pregnancy
  3. with a normal structural examination as much as possible;
  4. At least 2 US examination after pPROM for gestational age confirmation and diagnosis of persistent oligohydramnios
  5. Follow up ultrasound examinations weekly in the treatment group
  6. Acceptance of randomisation and to comply with the protocol

Exclusion criteria

Exclusion Criteria:

  1. Maternal to intervention or prolongation of pregnancy, including severe medical conditions in pregnancy that make fetal intervention riskful;
  2. Preterm labour defined as contractions >6/hour associated with cervical changes, cervix shortened (\<15 mm at randomization),
  3. Cervical cerclage in place
  4. Chorioamnionitis, defined as 2 or more of the following: maternal temperature>38 degrees, foul-smelling vaginal discharge, uterine tenderness, fetal tachycardia>170 bpm, white blood cell count >18,000
  5. Fetal structural anomaly detected at prenatal ultrasonography, or fetal chromosomal abnormalities involving autosomes
  6. Previous invasive procedure in this index pregnancy
  7. Fetal condition mandating immediate delivery
  8. Severe bleeding
  9. Maternal and infection
  10. Multiple gestation

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

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 Jan 22, 2009, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
