Routine Ultrasound Screening in the Third Trimester (RECRET)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01594463

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.

Arm Intervention/treatment
Experimental: late ultrasound examination
late examination between 34+1 weeks to 35+6 weeks.
Other: ultrasound examination
ultrasound examination between 34+1 weeks to 35+6 weeks

Experimental: early ultrasound examination
early examination between 30+1 weeks to 31+6 weeks
Other: ultrasound examination
ultrasound examination between week 30+1 weeks to 31+6 weeks

Primary Outcome Measures :
  1. 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.

Secondary Outcome Measures :
  1. 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 ]
  2. 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 ]
  3. Maternal complications and neonatal outcomes. [ Time Frame: In the postpartum period ]
