Brief Summary

The aim of our study was to investigate the correlation between the umbilical resistance index and weight gain during the third trimester of low-risk pregnancies.

Conditions

Umbilical Doppler

Keywords

Ultrasound; umbilical Doppler; resistance index; fetal growth

Outcome Measures

Primary Outcomes (1)

• fetal growth

  . During routine prenatal third trimester ultrasonography patients had a fetal weight estimation and measurement of the umbilical resistance index. After delivery we took note of the weight at birth, the term of the delivery, and the time interval between the ultrasound and the delivery, and then we calculated the weight gain on a weekly basis.

Eligibility Criteria

• Sex: female
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Any pregnant patient with a normally progressing pregnancy and reporting for a prenatal screening ultrasound between 31 and 34 weeks amenorrhea.

You may qualify if:

• Any pregnant patient with a normally progressing pregnancy and reporting for a prenatal screening ultrasound between 31 and 34 weeks amenorrhea.

You may not qualify if:

• The lack of an ultrasound carried out during the first trimester to confirm the term of the pregnancy.
• A medical condition in the mother: diabetes, high blood pressure or a known chronic illness.
• A medical condition in the fetus: suspicion of fetal hypotrophy (fetal biometrics lower than the 10th percentile), a birth defect (a chromosomal abnormality) during the pregnancy.
• Patients with tobacco addiction.
• A body mass index (BMI) ≥ 30 before the pregnancy.
• Multiple pregnancies
• A gap of less than 4 weeks between the date of the ultrasound and the date of delivery.
