Study summary

To predict the effect of antioxidants in cases of oligohydramnios

Read the detailed description

Type of study:

This is a prospective randomized controlled study that was done in department of obstetrics and gynecology of Assiut University Hospital.

Aim of the work:

  1. To study the effect of antioxidants in cases of oligohydramnios.
  2. To study the effect of antioxidants on mode of delivery and neonatal outcome.
  3. To commence special recommendations from the study about the use of antioxidants in cases of oligohydramnios of unknown cause and cases of oligohydramnios associated with pregnancy induced hypertension.

Inclusion criteria:

Patients with gestational age between 30-34 weeks with:

  • Oligohydramnios of unknown cause.
  • Oligohydramnios assosiatd with Pregnancy induced hypertension (PIH).

Exclusion criteria:

  1. Premature rupture of membranes.
  2. Oligohydramnios in postdates pregnancy (>41 weeks).
  3. Fetal anomalies.
  4. IUGR.
  5. Patients using non steroidal anti-inflammatory drugs.

Assessment of the patients:

The target population was assessed to find the participating women suitable for the study, this assessment was done to verify inclusion criteria and to exclude any women has any of the exclusion criteria.

Ultrasongraphic evaluation:

Ultrasongraphy was done for estimation of amniotic fluid index by measuring the vertical diameter of the pockets of amniotic fluid in four sections of the uterus and add them together. This gives them a number known as amniotic fluid index (AFI). If the AFI is less than 5 centimeters, the pregnant woman has oligohydramnios

Composition of omega-3 plus:

Soft gelatineous capsule (Sedico medical company) each capsule contains:

  • Fish oil (30) % (Eicosapentaenoic acid (EPA) 18 % / Docosahexaenoic acid (DHA) 12 % ) natural source of Omega 3 Fatty acids.
  • Wheat germ oil (Tocopherol: N.N.T. 0.22 %) which is rich and natural source of Vitamin E (protects the oils from oxidation. besides its well known that requirements of vitamin E increases with increased dietary amounts of polyunsaturated fatty acids).

Study arms

  • Active comparator
    anti oxidant omega 3

    The patients were randomized to receive either a daily dose of omega-3 plus as antioxidant once daily for two weeks or a daily placebo then stored in envelopes numbered from 1 to 140

    Drug: anti oxidant omega 3

  • Placebo comparator
    placebo

    Group 1 was given omega -3 plus (Sedico medical company) as antioxidant once daily for two weeks. Group 2 was given a placebo once daily for two weeks.

    Drug: anti oxidant omega 3

Interventions

  • Druganti oxidant omega 3

    Soft gelatineous capsule (Sedico medical company) each capsule contains: * Fish oil (30) % (Eicosapentaenoic acid (EPA) 18 % / Docosahexaenoic acid (DHA) 12 % ) natural source of Omega 3 Fatty acids. * Wheat germ oil (Tocopherol: N.N.T. 0.22 %) which is rich and natural source of Vitamin E (protects the oils from oxidation. besides its well known that requirements of vitamin E increases with increased dietary amounts of polyunsaturated fatty acids). Group 1 was given omega -3 plus (Sedico medical company) as antioxidant once daily for two weeks.

What researchers measure

Primary outcomes

  1. improvement of amniotic fluid index

    Treatment was started immediately and continued for two weeks. The patients were randomized to receive either a daily dose of omega-3 plus as antioxidant once daily for two weeks or a daily placebo then stored in envelopes numbered from 1 to 140. The envelopes were numbered and randomized according to computer-generated randomization tables to ensure an equal number of patients in each arm. Throughout the trial, access to the randomization code was available only to the pharmacist who manufactured the placebo and packed the envelopes and was not available to any of the treating physicians or patients.

    Time frame: 4 weeks

Secondary outcomes

  1. The changes in Doppler resistance index

    The resistance index is measured in the uterine and umbilical artery by ultrasound

    Time frame: 4 weeks

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 Aug 18, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
