Intervention/exposure
Study type
Interventional
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.
Intervention code [1] 288639 0
Treatment: Surgery
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.
Control group
Active

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following consent from parents and treatment team, infants are allocated to the study arms by central randomisation by computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computerised sequence generation.
Masking / blinding
Open (masking not used)

Intervention assignment
Other
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.
Phase
Not Applicable
Type of endpoint/s
Efficacy
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.
