Pulmonary hypertension may coexist with certain diseases in neonates. Iloprost inhalation is one of the treatments which cause selective pulmonary vasodilatation. Inhalation is not an easy way of drug administration in mechanically ventilated infants; as some exhibit desaturations during inhalation. Moreover, inhalation of drug requires cessation of mechanical ventilation, if patient is on high frequency oscillatory ventilation. We presented two patients with pulmonary hypertension; term baby with congenital diaphragmatic hernia and preterm baby with respiratory distress syndrome; who had iloprost instillation during mechanical ventilation treatment...

BACKGROUND: Although routine administration of pharmacologic sedation or analgesia during mechanical ventilation in preterm neonates is not recommended, its use in clinical practice remains common. Alpha-2 agonists, mainly clonidine and dexmedetomidine, are used as adjunctive (or alternative) sedative agents alongside opioids and benzodiazepines. Clonidine has not been systematically assessed for use in neonatal sedation during ventilation. OBJECTIVES: To assess whether clonidine administered to term and preterm newborn infants receiving mechanical ventilation reduces morbidity and mortality rates...

The aim of this pilot study was to determine Clara cell protein (CC16) concentration in bronchoalveolar lavages (BAL) fluid from full-term and preterm (<37 weeks' gestational age) neonates requiring respiratory support, having symptoms of neonatal respiratory distress syndrome, and at risk of bronchopulmonary dysplasia (BPD). We hypothesized that CC16 may be predictive of BPD diagnosis regardless of gestational age. BAL fluid CC16 was measured by ELISA at birth and at day 7 of life. Both groups that developed BPD showed significantly decreased BAL fluid CC16 levels compared to those infants that did not develop the disease...

OBJECTIVE: The association between infection and inflammatory response in singleton preterm birth (PTB) is well established, yet, less is known about PTB in twins. We aimed to compare the placental component and pregnancy outcome in pregnancies complicated with PTB of singletons vs. twin deliveries. We hypothesized that due to different underlying mechanisms, placental inflammatory lesions will be more prevalent in placentas derived from singleton pregnancies than twins. STUDY DESIGN: Labor characteristics, neonatal outcome and placental histopathology reports of spontaneous PTB at 24-33(6)/7 weeks, from 1/2008-12/2015, were reviewed...

PURPOSE: The aim of this study is to examine whether advanced magnetic resonance imaging (MRI) techniques can detect early brain injury caused by intrauterine inflammation and inappropriate initial respiratory support in preterm lambs. HYPOTHESIS: Neuropathology caused by intrauterine inflammation is exacerbated by mechanical ventilation at birth and is detectable with advanced MRI techniques. METHODS: Pregnant ewes received intra-amniotic lipopolysaccharide (LPS) 7 days prior to delivery at ~125 days of gestation (85% of gestation), whereupon lambs were delivered and randomised to receive an injurious (LPS + INJ, n = 6) or protective (LPS + PROT, n = 6) ventilation strategy...

REVIEW

Improvements in clinical management of the preterm infant have reduced the rates of the two most common forms of brain injury, such as severe intraventricular hemorrhage and white matter injury, both of which are contributory factors in the development of cerebral palsy. Nonetheless, they remain a persistent challenge and are associated with a significant increase in the risk of adverse neurodevelopment outcomes. Repeated episodes of ischemia-reperfusion represent a common pathway for both forms of injury, arising from discordance between systemic blood flow and the innate regulation of cerebral blood flow in the germinal matrix and periventricular white matter...

Respiratory syncytial virus (RSV) prophylaxis in high-risk infants is an effective intervention for the prevention of severe disease. The aim of this study was to determine the ideal target preterm population that might benefit from palivizumab prophylaxis by establishing the main risk factors for acute RSV-related infections. Former premature infants born with a gestational age ≤37 weeks and ≤1 year of age at the beginning of the RSV season and admitted with respiratory infection were included. RSV status was evaluated by RSV strip test in all infants...

BACKGROUND: Pulmonary dead space (VD) is an index of ventilation inhomogeneity and one of the determinants of the magnitude of tidal volume to maintain optimal blood gases. AIMS: To identify the determinants of VD in ventilated newborns and to investigate differences in VD between prematurely born and term infants and those prematurely born infants who did or did not develop bronchopulmonary dysplasia (BPD). METHODS: Sixty-one mechanically ventilated infants (15 term, 46 preterm) were studied at a median age of 8 (IQR 2-31) days; 32 of the preterm infants developed BPD...

A preterm infant with prenatal diagnosis of hydrops fetalis was spontaneously delivered at 30 weeks of gestational age in a tertiary level hospital. Prenatal echography pointed out severe bilateral pleural effusions and diffused subcutaneous edema. A neonatologist team, alerted at the expulsion stage of labor, assisted the neonate immediately after birth and bilateral hydrothorax was drained with intact placental circulation to avoid a nonrespiratory period and its possible detrimental hemodynamic effects. The newborn was well stabilized in the delivery room before cutting the umbilical cord and starting mechanical ventilation...

A 34-year-old woman at 25 weeks 3 days was diagnosed with preterm labor and underwent an emergency cesarean section. The neonate did not cry or show any activity. The heart rate was 80 beats/min and the oxygen saturation on pulse oximetry (SpO2) was 77%. Immediately, positive pressure ventilation was delivered by T piece resuscitator, and then anesthesiologist performed endotracheal intubation. The neonate demonstrated severe cyanosis and the SpO2 dropped to 30%. Ventilation was not successful even after intubation, and we found neck crepitus, chest wall distension, and severe cyanosis on physical examination...

Ventilation of preterm neonates causes pulmonary inflammation that can contribute to lung injury, propagate systemically and result in long-term disease. Modulation of this initial response may reduce lung injury and its sequelae. We aimed to determine the effect of human amnion epithelial cells (hAECs) on immune activation and lung injury in preterm neonatal lambs. Preterm lambs received intratracheal hAECs (90x106) or vehicle, prior to 2 h of mechanical ventilation. Within 5 min of ventilation onset, lambs also received intravenous hAECs (90x106) or vehicle...

BACKGROUND: Respiratory morbidity including respiratory distress syndrome (RDS) is a serious complication of preterm birth and the primary cause of early neonatal mortality and disability. While researching the effects of the steroid dexamethasone on premature parturition in fetal sheep in 1969, Liggins found that there was some inflation of the lungs of lambs born at gestations at which the lungs would be expected to be airless. Liggins and Howie published the first randomised controlled trial in humans in 1972 and many others followed...
