Insights

Treating patent ductus arteriosus (PDA) and its duration are linked to spontaneous intestinal perforation (SIP) in premature infants. Both intervention and non-intervention strategies for PDA show associations with SIP risk.

Area of Science:

  • Neonatal Medicine
  • Pediatric Cardiology
  • Gastroenterology

Background:

  • Patent ductus arteriosus (PDA) is common in preterm infants.
  • Spontaneous intestinal perforation (SIP) is a serious complication in neonates.

Purpose of the Study:

  • To investigate the relationship between PDA characteristics (duration, magnitude) and medical treatments with SIP incidence.
  • To determine if PDA management strategies influence SIP risk.

Main Methods:

  • Retrospective chart review of infants born <29 weeks gestation (2006-2018).
  • Evaluation of echocardiographic findings using the McNamara and Sehgal staging system.

Main Results:

  • Infants with SIP had a higher incidence of hemodynamically significant PDA (HSPDA) and received NSAIDs or paracetamol more frequently.
  • Persistence of HSPDA increased SIP odds by 1.32 per day in untreated infants.
  • Treatment of non-HSPDA was associated with a 2.35 increase in SIP odds per drug dose.

Conclusions:

  • Both medical treatment of non-hemodynamically significant PDA and non-intervention for HSPDA are associated with SIP.
  • PDA management requires careful consideration of potential SIP risks.
