Brief Summary

A large patent ductus arteriosus (PDA) is associated with congestive heart failure, pulmonary hemorrhage, chronic lung disease (CLD), necrotizing enterocolitis (NEC) and intraventricular bleeding. Indomethacin is the first line of treatment for PDA. Failure of ductal closure with the first course of indomethacin is reported in 30-40% of infants, with a higher failure rate in infants weighing \< 1000 gm. PDA ligation is associated with early postoperative hypotension, oxygenation failure and adverse neurodevelopmental outcome in preterm infants. The use of escalating doses of Indomethacin in the treatment of persistent PDA was found to be safe and decreased the need for PDA ligation without adverse effects in one observational study.We hypothesize that the use of an escalated dose of intravenous indomethacin will result in an increase in the probability of survival without need for surgical ligation of PDA as compared to a standard dose indomethacin in newborn infants \< 29 weeks of gestational age with persistent PDA.

Outcome Measures

Primary Outcomes (1)

  • Survival without PDA ligation at discharge

    till the discharge from hospital

Secondary Outcomes (2)

  • PDA closure rate

    after completion of indomethacin treatment

  • Incidence of necrotizing enterocolitis, renal failure and bronchopulmonary dysplasia

    till discharge from hospital

Study Arms (2)

Standard dose group

PLACEBO COMPARATOR

The infants randomized to the standard dose group will receive indomethacin (0.1 mg/kg) at 24 hr intervals for 5 days. These infants will also receive 5 extra doses of normal saline infusion of similar volume at 12 hrly intervals between the indomethacin schedules to match the Escalating dose Indomethacin Schedule

Drug: Indomethacin

Escalating dose group

ACTIVE COMPARATOR

The infants randomized to the Escalating dose group will receive indomethacin started at 0.2 mg/kg/dose every 12 hours for 2 doses with stepwise increment in indomethacin dose by 0.1 mg/kg/dose every 24 hours upto maximum dose of 0.6 mg/kg/dose

Drug: Indomethacin

Interventions

Infants randomized to Escalating Dose group will receive indomethacin (0.2 mg/kg/dose) at 12 hr intervals for 2 doses, followed by indomethacin (0.3 mg/kg/dose) at 12 hr interval for 2 doses, then Indomethacin (0.4 mg/kg/dose) at 12 hr interval for 2 doses, increased to indomethacin (0.5 mg/kg/dose) at 12 hour interval for 2 doses and finally indomethacin 0.6 mg/kg/dose at 12 hourly interval for 2 doses.

Eligibility Criteria

AgeUp to 4 Weeks
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Preterm infants with gestational age \< 29 weeks and/or birth weight \< 1251gm
  • Presence of PDA after completion of first course of indomethacin

You may not qualify if:

  • Infants with PDA dependent congenital heart disease
