Clinical Trial: Routine Ultrasound Screening in the Third Trimester

Official Title: Third Trimester Routine Ultrasound in Low-risk Pregnancies : Comparison of Two Timing Periods Procedure for Screening Intrauterine Growth Restriction

Brief Summary: Late intrauterine growth restriction is infrequently diagnosed with an overall sensitivity of 40 % in low-risk pregnancies. In addition, late intrauterine growth restriction may be associated with intrauterine death and poor neonatal outcomes i.e. birth asphyxia and hospitalization in intensive care unit. The investigators hypothesis that a later third trimester routine ultrasound may be more accurate to diagnose late intrauterine growth restriction.

Detailed Summary:
Sponsor: University Hospital, Rouen

Current Primary Outcome: Number of small for gestational age infant screened by a routine ultrasound in the third trimester (sensitivity). [ Time Frame: At birth ]

SGA infant and intrauterine growth restriction are defined using a threshold below the tenth percentile for customized birth weight or customized estimated birth weight.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Number of neonate with a customized birth weight upper the tenth percentile adequately screened by a routine ultrasound in the third trimester (specificity). [ Time Frame: At birth ]
  • Number of prenatal consultations, ultrasound scans performed, maternal hospitalization, labor induction, and caesarean section induced by the third trimester routine ultrasound [ Time Frame: After the delivery ]
  • Maternal complications and neonatal outcomes. [ Time Frame: In the postpartum period ]


Original Secondary Outcome: Same as current
