Home oxygen in preterm infants

OBJECTIVE: We aim to identify potential risk factors associated with longer duration of supplemental oxygen use in preterm infants at risk for bronchopulmonary dysplasia (BPD) to better inform families and weaning protocols. STUDY DESIGN: This is a retrospective study of infants with a birth gestational age (GA) < 32 0/7 weeks admitted to the neonatal intensive care unit (NICU) between October 2017 and September 2019. RESULTS: A total of 172 infants met criteria for inclusion and analysis, of which 69 (40...

OBJECTIVE: This study aimed to compare the short- and long-term outcomes of extremely preterm small-for-gestational-age (SGA) infants and appropriate-for-gestational-age (AGA) infants in Japan. STUDY DESIGN: We retrospectively assessed 434 SGA and 1716 AGA infants born at 22-27 weeks of gestational age (GA), between 2003 and 2012. Infants were followed up for 3 years, and the clinical characteristics and outcomes were compared. Fisher's exact and Student's t-tests were used for independent sample comparison...

Coronavirus disease 2019 (COVID-19) was first reported to the World Health Organization (WHO) in December 2019 and has since unleashed a global pandemic, with over 518 million cases as of May 10, 2022. Neonates represent a very small proportion of those patients. Among reported cases of neonates with symptomatic COVID-19 infection, the rates of hospitalization remain low. Most reported cases in infants and neonates are community acquired with mild symptoms, most commonly fever, rhinorrhea and cough. Very few require intensive care or invasive support for acute infection...

BACKGROUND: Home oxygen therapy (HOT) is indicated upon discharge in some preterm infants with severe bronchopulmonary dysplasia (BPD). There is a lack of evidence-based consensus on the indication for HOT among these infants. Because wide variation in the institutional use of HOT exists, little is known about the role of regional social-economic level in the wide variation of HOT. METHODS: This was a secondary analysis of Chinese Neonatal Network (CHNN) data from January 1, 2019 to December 31, 2019...

OBJECTIVE: To determine clinical correlates of moderate to severe bronchopulmonary dysplasia (BPD) in preterm infants following surgical necrotizing enterocolitis (NEC). METHODS: A retrospective, single-center cohort study comparing patients with moderate to severe BPD to patients with non/mild BPD among surgical NEC infants. BPD was defined by NIH 2001 consensus definition Results: Of 92 consecutive neonates with surgical NEC, 77% (71/92) had moderate/severe BPD and 22% (21/92) had non/mild BPD...

OBJECTIVE: To evaluate the impact of immunoprophylaxis with palivizumab in preterm infants less than 35 weeks in terms of hospitalization rate, intensive care unit requirement, and mortality. METHODS: A prospective cohort study was conducted at six Colombian hospitals. Preterm infants less than 35 weeks who received at least one dose of palivizumab during the first 6 months of life were included. The primary outcome was the hospitalization rate related to respiratory syncytial virus (RSV) infection...

OBJECTIVES: We aimed to evaluate the impact of hypertensive disorders of pregnancy (HDP) on short- and medium-term respiratory outcomes in extremely and very preterm infants using the Neonatal Research Network of Japan database. STUDY DESIGN: This was a population-based retrospective study of preterm infants weighing ≤ 1500 g born between 22 and 31 weeks of gestation between 2003 and 2017. After 1:1 stratification matching by four factors (maternal age, gestational age, parity, and year of delivery), a total of 5137 infants in each group (HDP and non-HDP groups) were selected...

INTRODUCTION: Postnatal steroids during the first few weeks of life have been demonstrated to be effective in decreasing the incidence of bronchopulmonary dysplasia (BPD), a serious chronic respiratory condition affecting preterm infants. However, this preventive option is limited by the concern of neurological side effects. Steroids are used to treat established BPD in an attempt to reduce mortality, and length of stay and home oxygen therapy, both of which associated with high levels of parental stress and healthcare costs...

Extremely preterm infants commonly suffer from respiratory distress syndrome. Ventilatory management of these infants starts from birth and includes decisions such as timing of respiratory support in relation to umbilical cord management, oxygenation targets, and options of positive pressure support. The approach of early intubation and surfactant administration through an endotracheal tube has been challenged in recent years by primary noninvasive respiratory support and newer methods of surfactant administration via thin catheters...

Background  During neurally adjusted ventilatory assist (NAVA)/noninvasive (NIV) NAVA, a modified nasogastric feeding tube with electrodes monitors the electrical activity of the diaphragm (Edi). The Edi waveform determines the delivered pressure from the ventilator. Objective  Our objective was to determine whether NAVA/NIV-NAVA has advantages in infants with evolving/established bronchopulmonary dysplasia (BPD). Methods  Each infant who received NAVA/NIV-NAVA and conventional invasive and NIV was matched with two historical controls...

BACKGROUND: Approximately a third of all extremely preterm infants diagnosed with bronchopulmonary dysplasia will require home oxygen therapy (HOT). Lack of consensus-based guidelines has led to significant variability in outpatient HOT management in the United States. A common assessment performed before discontinuing oxygen is a formal polysomnogram (PSG). PSGs are potentially undesirable due to cost, lack of convenient access, and parental stress, so alternative testing to determine the optimal timing of safe oxygen discontinuation are needed...

OBJECTIVE:  Factors influencing utilization of outpatient interventional therapies for extremely low gestational age newborns (ELGANs) after discharge remain poorly characterized, despite a significant risk of neurodevelopmental impairment. We sought to assess the effects of maternal, infant, and environmental characteristics on outpatient therapy utilization in the first 2 years after discharge using data from the Preterm Erythropoietin Neuroprotection (PENUT) Trial. STUDY DESIGN:  This is a secondary analysis of 818, 24 to 27 weeks gestation infants enrolled in the PENUT trial who survived through discharge and completed at least one follow-up call or in-person visit between 4 and 24 months of age...

BACKGROUND: Gastroesophageal reflux (GER) is more frequent in premature infants. Metoclopramide was introduced routinely in premature babies followed in ambulatory care by the Colombian Kangaroo Mother Care program (KMCP), based on a 2004 Cochrane review. AIM: Because of the recent controversy on the use of metoclopramide in children, this study was conducted to evaluate the effectiveness and safety of metoclopramide given as GER disease (GERD) prophylaxis. METHODS: A randomized clinical trial was conducted between April 2017 and January 2019 in 466 premature infants discharged home and followed at a KMCP...

OBJECTIVES: To study the demographic and clinical characteristics of preterm infants with bronchopulmonary dysplasia (BPD) to identify the factors most strongly predictive of outpatient mortality, with the goal of identifying those individuals at greatest risk. STUDY DESIGN: Demographic and clinical characteristics were retrospectively reviewed for 862 subjects recruited from an outpatient BPD clinic. Characteristics of the deceased and living participants were compared using nonparametric analysis...

INTRODUCTION: Exposure to mechanical ventilation (MV) is a risk factor for bronchopulmonary dysplasia (BPD) in very preterm infants (VPTIs). We assessed the impact of a quality improvement (QI) bundle in VPTIs (<32 week gestation) on exposure to MV. METHODS: We introduced a QI bundle consisting of deferred cord clamping (DCC), nasal bubble continuous positive airway pressure (bCPAP) in the delivery room (DR), and minimally invasive surfactant therapy (MIST). We compared respiratory outcomes and neonatal morbidity in historical pre-QI (July-December 2017) and prospective post-QI (February-July 2019) cohorts (QICs) of VPTIs...

Objective: The goal of the current study was to assess the associations of typical chest imaging findings of bronchopulmonary dysplasia (BPD) in preterm infants with clinical characteristics and outcomes until 2 years of age. Method: This retrospective cohort study enrolled 256 preterm infants with BPD who were admitted between 2014 and 2018. A propensity score analysis was used to adjust for confounding factors. The primary outcomes were the severity of BPD, home oxygen therapy (HOT) at discharge and mortality between 28 days after birth and 2 years of age...

OBJECTIVE:  This study aimed to determine the predictive abilities of the National Institute of Child Health and Human Development (NICHD) 2018 definition of bronchopulmonary dysplasia (BPD) on mortality and pulmonary outcomes of preterm infants at 20 to 24 months' corrected age and compare them with the National Institutes of Health (NIH) 2001 definition. STUDY DESIGN:  A retrospective cohort study was conducted in a level III neonatal intensive care unit (NICU) in Bangkok, Thailand...

AIM: The delivery room intubation rate for babies born less than 32 weeks postmenstrual age (PMA) at the Mater Mothers' Hospital in 2017 was 51%. Delivery room intubation of preterm infants may be associated with an increased risk of developing bronchopulmonary dysplasia. This quality improvement project aimed to decrease the rate of delivery room intubation for infants born less than 32 weeks PMA. METHODS: A quality improvement process using the evidence-based practice for improving quality framework and Plan-Do-Study-Act cycles was undertaken from October 2018 to December 2019...

It is well known that supplemental oxygen used to treat preterm infants in respiratory distress is associated with permanently disrupting lung development and the host response to influenza A virus (IAV). However, many infants who go home with normally functioning lungs are also at risk for hyperreactivity after a respiratory viral infection. We recently reported a new, low-dose hyperoxia mouse model (40% for 8 days; 40x8) that causes a transient change in lung function that resolves, rendering 40x8 adult animals functionally indistinguishable from room air controls...

OBJECTIVES: Diuretics are often given to infants with evolving/established bronchopulmonary dysplasia (BPD) with the hope of improving their pulmonary outcomes. We aimed to determine if diuretic use in preterm infants was associated with improved pulmonary outcomes, but poorer weight gain. METHODS: An observational study over a 5 year period was undertaken of all infants born at less than 29 weeks of gestation and alive at discharge in all neonatal units in England who received consecutive diuretic use for at least 7 days...
