Study information

Scientific title

Randomised controlled trial of early versus late initiation of milk feeds for infants with absent or reversed end diastolic flow velocities (AREDFV) or cerebral redistribution



Study hypothesis

The aim is to evaluate the effects of an 'early' enteral feeding regimen, starting milk feeds on day 2 after birth (between 24 and 48 hours of age) compared to one of 'late' introduction of enteral feeds, starting feeds on day 6 after birth (between 120 - 144 hours of age) in a group of babies identified as being at high risk for necrotising enterocolitis (NEC) and milk intolerance by antenatal Doppler studies.

Added 23/11/2007:
Please note that due to an extension in funding from Action Medical Research the anticipated end date of this trial has been extended to 31/12/2008. The previous end date of this trial was 05/03/2008.

Ethics approval

Oxfordshire Research Ethics Committee (REC) C gave approval on the 27th September 2005 (ref: 05/Q1606/121)

Feeding of preterm infants after absent or reversed end-diastolic flow velocities (AREDFV). Babies will be randomly allocated to an 'early' or 'late' enteral feeding regimen. These will start milk feeds on day 2 and day 6 after birth, respectively.

2. Duration of hospital stay
3. Duration of intensive and high dependency care
4. Duration of parenteral nutrition
5. Change in Z score for weight and head circumference from birth to 36 weeks postmenstrual age and from birth to discharge
6. In continuous supplemental oxygen at 36 weeks post-menstrual age
7. Confirmed bacterial sepsis

3. Small for gestational age
4. Postnatal age 20 - 48 hours
