Description of intervention(s) / exposure
Treatment group: Rectal washout with normal saline (10-20ml/kg for baby less than 1 kg, 20-40ml/kg for baby more than 1kg, twice a day) if infants failed to pass meconium at 48 hours of age, and rectal washout is continued until 1 day of yellow stools or equal to or more than 110ml/kg/day of feeds; whichever is earlier.

Comparator / control treatment
Infants are administered gylcerine suppository (1/4) if baby failed to pass meconium in 48 hours. If meconium is passed, feeds are tolerated, suppositories will be discontinued. If problems persist, i.e. feed intolerance/ abdominal distention, babies are referred to paediatric surgeon who will initiate rectal washout.

Other design features
Interventional arm receive only rectal washout. However, the conventional management can receive rectal washout if glycerine suppository fails. Both arms can receive contrast enema and laparotomy according to surgeon discretion if rectal washout in study arm or glycerin suppository+ rectal washout in conventional arm fails.

Statistical methods / analysis
The effect of early aggressive meconium evacuation with rectal washout versus conventional management with glycerin suppository will be evaluated using survival analysis. The Cox Propertional Hazards (PH) model will be used to assess the treatment effect, expressed as a hazard ratio (with 95% confidence interval) adjusted for the effect of birth weight (<1kg versus 1-1.5kg) and other prognostic factors, as necessary. Covariate-dependent confidence intervals for the difference between median during times under a stratified Cox PH model will be derived using the method of Chen and Chang (2007). The Kaplan-Meier technique will be used to derive cumulative incidence rates at the end of the study and construct plots.
Sample size: To detect a difference of in the median duration to full oral feeds of equal to or more than 110mlkg/day in a two sided test at alpha=0.05 and 1-0.80, assuming that the median duration under control is M1 days, and under treatment is M2 days, a sample of size n is required. Final study size will depend on pilot study estimates.

Summary
Brief summary
Meconium is the first stool all infants passes after birth. It is sticky and is black green colour. Infant's small and large guts are filled with meconium at birth. Meconium retention has become a recognized cause of bowel dysfunction in VLBW infants, causing delay in grading up of enteral feeds. Our goal is to shorten the duration to reach full oral feeds by aggressive meconium evacuation, thereby reducing the duration of NICU stay, incidence of necrotizing enterocolitis and sepsis, number of days an infant remains in total parental nutrition (TPN) and number of phototherapy days. Our primary hypothesis is that early evacuation of meconium with regular daily normal saline rectal washout (RW) in VLBW infants (750-1500g) with failed bowel opening for 48 hours reduces the duration to reach full feeds (equal to or more than 110ml/kg/day) as compared to conventional management with glycerin suppositories. 60 infants born over 18 months period from November 2013 in KK Hospital (KKH), Singapore will be enrolled. Infants are randomized at 48 hrs of age. Treatment group will receive RW at 48 hours of age and continued until 2 days of yellow stools or until infant reaches full feeds, whichever is earlier. Control group will follow conventional management protocol. Infants are followed up to 36 weeks of gestation or discharge whichever is earlier. Maternal and infant characteristics will be collected.
