Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Our global aim is to assess if LMWH improves the outcomes of early-restricted fetuses (ERF).;Secondary Objective: 1) To determine if enoxaparin increases the mean neonatal birth weight and decreases neonatal intensive care admissions 2) To determine if enoxaparin improves maternal and fetal Doppler parameters in this group of patients 3) To determine if enoxaparin is associated with alterations in placental pathology 4) To determine if enoxaparin is associated with alterations in Sflt1-PLGF ratio 5) To determine if there is a change in number or composition of STD-EV between healthy and FGR pregnancies 6) To determine if enoxaparin is associated with alterations in STD-EV in FGR pregnancies;Primary end point(s): Primary: Gestational age at delivery;Timepoint(s) of evaluation of this end point: At delivery | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary: Evolution of fetal doppler parameters (umbilical artery pulsatility index, middle cerebral artery pulsatility index, cerebral-placental ratio, ductus venosus pulsatility index); evolution of maternal doppler parameters (uterine artery pulsatility index); maternal weight gain during pregnancy; newborn weight, percentile, umbilical artery pH and Apgar score in the 5th minute; neonatal intensive care admission and duration of admission; a composite outcome of severe neonatal morbidity (evidence of one or more of: intraventricular hemorrhage grade 3 or 4; cystic periventricular leukomalacia; chronic lung disease; retinopathy of prematurity requiring treatment; necrotizing enterocolitis requiring surgery); gestational hypertension or preeclampsia; placental abruption; antepartum hemorrhage; maternal thrombocytopenia (platelets < 100 000 x 109/L); stillbirth; preterm birth; mode of delivery; indication for delivery; postpartum hemorrhage; placental pathology; sFLT1-PLGF ratio; STD-EV (number and composition) ;Timepoint(s) of evaluation of this end point: During all pregnancy and after delivery | — |
