Abstract

Patent Ductus Arteriosus (PDA) is one of acyanotic congenital heart diseases that often occurs in preterm infants and closely related to an increased risk of complications for sufferers. Identification of PDA risk factors in preterm infants is very important, so that the diagnosis and management can be done earlier. In this study we aimed to determine risk factors of PDA in preterm infants. This case-control study was conducted between July 2017 and April 2018, analysed 43 preterm infants with PDA as the case group and 43 preterm infants without PDA as the control group. The basic information related to characteristics, risk of infection and perinatal history in both groups were collected. Bivariate and multivariate analysis with logistic regression were performed to identify risk factors for PDA. We found several factors were identified significantly (P<0.05) as risk factors for PDA including premature rupture of membranes >12 hours (OR 7.25; 95% CI: 2.08 - 25.09) and thrombocytopenia in the first 24 hours (OR 15.11; 95% CI: 3.73 - 61.13). This study concluded premature rupture of membranes >12 hours and thrombocytopenia in the first 24 hours were proven to increase the risk of PDA in preterm infants.

Highlights

  • World Health Organization (WHO) noted that the incidence of preterm births in Indonesia in 2010 was 15.5 per 100 live births which ranked Indonesia as 9th highest among 184 countries

  • Patent Ductus arteriosus (PDA) is one of acyanotic congenital heart disease which has a high incidence in preterm birth [2]

  • Bivariate analysis with Chi Square test to get the variables that affect the incidence of PDA in preterm infants were premature rupture of membranes> 12 hours, gestational age

Summary

Introduction

World Health Organization (WHO) noted that the incidence of preterm births in Indonesia in 2010 was 15.5 per 100 live births which ranked Indonesia as 9th highest among 184 countries. If compared with other ASEAN countries, Indonesia has the highest incidence of preterm birth. Patent Ductus arteriosus (PDA) is one of acyanotic congenital heart disease which has a high incidence in preterm birth [2]. Sepsis is one of the risk factors for PDA. Premature rupture of membranes> 12 hours is a risk factor for infection and neonatal sepsis, but its relationship as a risk factor for PDA in preterm infants has not been studied. A retrospective study of preterm infants showed that thrombocytopenia was an independent factor in the occurrence of PDA [4]
