OBJECTIVE: To characterize the neural breathing pattern in preterm infants supported with non-invasive neurally adjusted ventilatory assist (NIV-NAVA). STUDY DESIGN: Single-center prospective observational study. The electrical activity of the diaphragm (EAdi) was periodically recorded in 30-second series with the Edi catheter and the Servo-n software (Maquet, Solna, Sweden) in preterm infants supported with NIV-NAVA. The EAdiPeak , EAdiMin , EAdiTonic , EAdiPhasic , neural inspiratory, and expiratory times (nTi and nTe) and the neural respiratory rate (nRR) were calculated...

Non-invasive ventilation is increasingly used for respiratory support in preterm infants, and is associated with a lower risk of chronic lung disease. However, this mode is often not successful in the extremely preterm infant in part due to their markedly increased chest wall compliance that does not provide enough structure against which the forces of inhalation can generate sufficient pressure. To address the continued challenge of studying treatments in this fragile population, we developed a nonlinear lumped-parameter respiratory system mechanics model of the extremely preterm infant that incorporates nonlinear lung and chest wall compliances and lung volume parameters tuned to this population...

BACKGROUND: Invasive mechanical ventilation (IMV) is associated with the development of adverse pulmonary and non-pulmonary outcomes in very premature infants. Various modes of non-invasive respiratory support are increasingly being used to decrease the incidence of bronchopulmonary dysplasia. The aim of this trial is to compare the effect of non-invasive high-frequency oscillatory ventilation (NHFOV) and nasal continuous positive airway pressure (NCPAP) in preterm infants with respiratory distress syndrome (RDS) as a primary non-invasive ventilation support mode...

OBJECTIVE: Longer initial hospitalizations for preterm infants with bronchopulmonary dysplasia (BPD) can delay family bonding and attainment of developmental milestones, increase the risk for hospital acquired complications, and increase healthcare costs. The goal of the study was to identify the characteristics associated with longer lengths of hospitalization in this high-risk population. STUDY DESIGN: A retrospective analysis was performed on 660 children (born ≤32 weeks gestation) discharged from 13 Maryland NICUs recruited into an outpatient BPD registry...

BACKGROUND: Complications of intravenous lipid administration are relatively uncommon. However, inadvertent rapid infusion of intravenous fat emulsion (IVFE) is an inherent risk when fats are infused separately from the dextrose-amino acid solution. CASE REPORT: Extremely preterm infant, born at 25 weeks and 6 days of gestational age weighing 920 g, who inadvertently received a massive overdose of IVFE due to a device failure. He developed lethargy, apnea, metabolic acidosis and hemodynamic instability requiring mechanical ventilation and inotropic support...

Early pulmonary interstitial emphysema in extreme preterm neonates is closely linked with respiratory distress syndrome and exposure to mechanical ventilation. In severe cases, maintaining adequate gas exchange aiming to avoid further lung damage and other neonatal morbidities associated with systemic/pulmonary hypoperfusion, prolonged hypoxia, and respiratory acidosis can be challenging and requires in-depth knowledge into the pathophysiology of the disease. Herein, we report on very low birth weight twins who developed early pulmonary interstitial emphysema during noninvasive respiratory support...

Preponderance of proinflammatory signals is a characteristic feature of all acute and resulting long-term morbidities of the preterm infant. The proinflammatory actions are best characterized for bronchopulmonary dysplasia (BPD) which is the chronic lung disease of the preterm infant with lifelong restrictions of pulmonary function and severe consequences for psychomotor development and quality of life. Besides BPD, the immature brain, eye, and gut are also exposed to inflammatory injuries provoked by infection, mechanical ventilation, and oxygen toxicity...

Healthy, premature infants ≤35 weeks' gestational age (wGA) are universally recognized to be at an increased risk of perinatal morbidity and mortality. Serious respiratory syncytial virus (RSV) lower respiratory tract infection imposes an additional burden of illness on these infants following hospitalization. Incurred morbidities relative to term infants include longer lengths of hospital stay, admission to intensive care, and need for oxygen and mechanical ventilation, all of which are associated with increased hospital costs...

Oxygenation instability is a very common problem in the premature infant that manifests as intermittent hypoxemia episodes (HEs). These are particularly frequent in premature infants who are on mechanical ventilation beyond the first weeks after birth. However, they can also occur in spontaneously breathing infants. Some of these episodes are due to central apnea, but in ventilated infants, they are frequently due to contractions of the abdominal musculature that can splint the respiratory pump, resulting in periods of decreased lung volume and hypoventilation...

In the 1990s, the most relevant pillars in the treatment of neonatal respiratory distress syndrome (RDS) have been improvements in ventilation strategies, the introduction of exogenous surfactant replacement therapy, and the use of antenatal steroids. Lately, in addition to the standard INSURE (INtubation-SURfactant administration-Extubation) method to administer surfactant, a new technique has been gaining increasing popularity. It is the so-called less invasive surfactant administration (LISA) method, which has shown promising results in preventing bronchopulmonary dysplasia development and in reducing mortality in preterm neonates...

Pneumothorax in preterm infants is associated with an increased risk of chronic lung disease, intraventricular hemorrhage and mortality. In mechanically ventilated preterm infants, for the management of tension pneumothorax if needle aspiration is not successful a thoracostomy is needed. In the last two decades management of tension pneumothorax has changed from the use of traditional chest tubes to percutaneous pigtail catheter thoracostomy (PPCT) as the most commonly used technique. When compared to placement of traditional chest tubes, PPCT is touted as being faster requiring, less analgesia and less training for proficiency and having fewer complications...
