What Should be the First-line Treatment for the Closure of Hemodynamically Significant Patent Ductus Arteriosus in Premature Infants?

Abstract

Background

It is important which medicine to use as a first-line treatment to close the duct.

Objectives

The aim of this study is to compare the effectiveness and side effects of intravenous (IV) forms of ibuprofen and paracetamol and to contribute to the literature investigating the first drug selected in the medical treatment of patent ductus arteriosus (PDA).

Methods

Our study was conducted between January 2017 and December 2019. Premature infants with birth weight (BW) ≤1500 g and gestational age (GA) ≤32 weeks were included in the study. In the study period, all infants with hemodynamically significant patent ductus arteriosus (hsPDA) were given rescue intravenous (IV) ibuprofen as a primary medical treatment or IV paracetamol treatment if there were contraindications for ibuprofen. The patients were divided into two groups: patients receiving IV ibuprofen and patients receiving IV paracetamol.

Results

Of these patients, 101 were given IV paracetamol and 169 were given IV ibuprofen. The success rate of PDA closure with first-course treatment was 74.3% in the IV paracetamol group and 72.8% in the IV ibuprofen group (p=0.212).

Conclusions

Our results show that IV paracetamol is as effective as IV ibuprofen in the first-line treatment of hsPDA, and can become the preferred treatment for the management of hsPDA.

Low birth weight as a marker of changes in ambulatory blood pressure monitoring

Cláudia Maria Salgado et al. Paulo César Brandão Veiga Jardim Flávio Bittencourt Gonçalves Teles Mariana Cabral Nunes

BACKGROUND: Low birth weight (LBW) is associated with increased incidence of high blood pressure (BP) and cardiovascular diseases in adulthood. OBJECTIVE: To evaluate possible changes in Ambulatory Blood Pressure Monitoring (ABPM) in LBW children. METHODS: The birth weight (BW) of 1049 school children (ages 8 to 11) living in Goiânia was assessed. Children with low birth weight (BW 3.0 Kg). Information on birth weight was obtained from each child’s health card. Casual BP and ABPM were measured. Height and weight measurements were obtained to calculate the body mass index (BMI), and sexual maturity was assessed according to Tanner’s criteria (those at Tanner stage > 2 were excluded). RESULTS: Thirty-four children had low birth weight (LBW) and 34 had normal birth weight (NBW). Both groups were similar regarding age, gender, race, body weight, height, BMI, and family history of hypertension. Low-birth-weight children had higher casual systolic blood pressure (SBP) (p = 0.007). ABPM recordings showed that these children had higher 24-hour diastolic blood pressure (DBP) (p = 0.009), daytime DBP (p = 0.002), night-time DBP and SBP (p = 0.005 and p = 0.001), and reduced nocturnal dip in SBP and DBP (p = 0.001) than those born with normal weight. Birth weight was positively correlated with nocturnal dip in SBP (p = 0.022) and negatively correlated with sleep SBP (p = 0.032). CONCLUSION: Low-birth-weight children have higher BP and changes in circadian rhythm of blood pressure, with reduced nocturnal dipping. These findings may reflect increased risk of adult hypertension and cardiovascular diseases.
