[Treatment of patent ductus arteriosus in preterm infants]
Insights
This study on premature infants with symptomatic patent ductus arteriosus (PDA) found that early closure of PDA can reduce complications. Infants under 1,500g had higher re-opening rates after indomethacin treatment.
Area of Science:
- Neonatal Medicine
- Pediatric Cardiology
- Perinatology
Context:
- Retrospective analysis of 38 preterm infants with symptomatic patent ductus arteriosus (PDA).
- PDA represented 4% of unit admissions between June 1978 and March 1980.
- 30 of 38 infants (79%) had PDA associated with Respiratory Distress Syndrome (RDS).
Purpose:
- To evaluate the treatment outcomes for symptomatic PDA in preterm infants.
- To assess the efficacy of indomethacin in pharmacologic closure of PDA.
- To identify factors influencing treatment success and failure rates.
Summary:
- Conservative medical treatment failed in 42% of cases, necessitating indomethacin.
- Infants with birth weight <1,500g showed higher re-opening rates (62.5%) and therapeutic failures (50%).
- Indomethacin response varied across patient groups, with lower birth weight infants faring worse.
Impact:
- Early PDA closure may decrease morbidity and mortality in preterm infants.
- Findings highlight the need for tailored treatment strategies, especially for very low birth weight neonates.
- Informs clinical practice regarding PDA management in high-risk premature populations.
Abstract:
A retrospective study is made on the results of the treatment of 38 preterm infants with symptomatic PDA; they represented an incidence of 4% of all the admissions to our Unit from June 1978 to March 1980. 30 of the 38 infants (79%) had PDA associated with RDS. Conservative medical treatment failed in 42% of the patients, requiring the administration of indomethacin for pharmacologic closure of their PDA. The different responses to the drug in each of the established groups are commented, being the group with a birth weight less than 1,500 g who presented the highest percentage of re-openings (62.5%) and of therapeutic failures (50%). An early closure of the PDA can contribute to decrease the morbidity and mortality of these infants, specially those with lower birth weight.
