High Frequency Oscillatory Ventilation Combined With Intermittent Sigh Breaths: Effects on Lung...

Respiratory Distress Syndrome In Premature InfantsBronchopulmonary Dysplasia2 more

Background Ventilator induced lung injury (VILI) remains a problem in neonatology. High frequency oscillatory ventilation (HFOV) provides effective gas exchange with minimal pressure fluctuation around a continuous distending pressure and therefore small tidal volume. Animal studies showed that recruitment and maintenance of functional residual capacity (FRC) during HFOV ("open lung concept") could reduce lung injury. "Open lung HFOV" is achieved by delivering a moderate high mean airway pressure (MAP) using oxygenation as a guide of lung recruitment. Some neonatologists suggest combining HFOV with recurrent sigh-breaths (HFOV-sigh) delivered as modified conventional ventilator-breaths at a rate of 3/min. The clinical observation is that HFOV-sigh leads to more stable oxygenation, quicker weaning and shorter ventilation. This may be related to improved lung recruitment. Electric Impedance Tomography (EIT) enables measurement and mapping of regional ventilation distribution and end-expiratory lung volume (EELV). EIT generates cross-sectional images of the subject based on measurement of surface electrical potentials resulting from an excitation with small electrical currents and has been shown to be a valid and safe tool in neonates. Purpose, aims: To compare HFOV-sigh with HFOV-only and determine if there is a difference in global and regional EELV (primary endpoints) and spatial distribution of ventilation measured by EIT To provide information on feasibility and treatment effect of HFOV-sigh to assist planning larger studies. We hypothesize that EELV during HFOV-sigh is higher, and that regional ventilation distribution is more homogenous. Methods: Infants at 24-36 weeks corrected gestational age already on HFOV are eligible. Patients will be randomly assigned to HFOV-sigh (3 breaths/min) followed by HFOV-only or vice versa for 4 alternating 1-hours periods (2-treatment, double crossover design, each patient being its own control). During HFOV-sigh set-pressure will be reduced to keep MAP constant, otherwise HFOV will remain at pretrial settings. 16 ECG-electrodes for EIT recording will be placed around the chest at study start. Each recording will last 180s, and will be done at baseline and at 30 and 50 minutes after each change in ventilator modus. Feasibility No information of EIT-measured EELV in babies on HFOV-sigh exists. This study is a pilot-trial. In a similar study-protocol of lung recruitment during HFOV-sigh using "a/A-ratio" as outcome, 16 patients was estimated to be sufficient to show an improvement by 25%. This assumption was based on clinical experience in a unit using HFOV-sigh routinely. As the present study examines the same intervention we assume that N=16 patients will be a sufficient sample size. We estimate to include this number in 6 months.

Oral Vitamin A Supplementation in Neonates With Birth Weight < 1500 g

Bronchopulmonary DysplasiaRetinopathy of Prematurity

Vitamin A is essential for optimal growth, and development. In the newborn, especially if preterm, it is necessary for the cellular differentiation, for the health of the anterior eye, it is a constituent of visual pigment, and it is essential for surfactant synthesis. Immune response Vitamin A supplementation demonstrated to reduces infancy mortality, but very low (<1500g birth weight) and extremely low (<1000g birth weight) preterm infants are born with low body stores of vitamin A and are at high risk of vitamin A deficiency. Nevertheless, optimal vitamin A supplementation for these infants is not clearly defined, despite evidence of benefit of an early supplementation. Prematurity is associate to the risk for bronchopulmonary dysplasia (BPD) which is a disease marked by respiratory compromise associated with high mortality and severe long-term morbidity, as well as prematurity is associate to the risk for retinopathy, a pathology that may be related to less rhodopsin quantity which seem dependent on vitamin A concentration. Vitamin A can be given enterally, intramuscularly, or intravenously. Recently an oral administration as drops is available resulting particularly convenient avoiding the pain associated with repetitive intramuscular injections, or the discomfort of parenteral administration. Studies of vitamin A in the infant population suggest that plasma retinol concentrations >0.7 µM/L indicate vitamin A sufficiency, nevertheless preterm infants have lower concentration and concentration < 0.35 µM/L are very dangerous. Vitamin A deficiency at this level may constitute a problem for preterm newborn, resulting for example, in histological alterations in the respiratory epithelium leading to chronic lung disease, retinopathy of prematurity, patency of the ductus arteriosis, and immune competence deficiency. The aim of the present study is to verify efficacy and tolerability of a new oral administration of vitamin A as drops, 3000 IU/kg/die for 4 weeks, in infants < 1500g weight at birth, verifying the competence of the supplementation reaching ideal blood concentration (≥0.7 µM/L) and relating the blood achieved concentrations of vitamin A to the outcome in typical pathologies, as BPD and ROP. Not treated group of matched newborn infants is the controlarm.

Enteral L Citrulline Supplementation in Preterm Infants - Safety, Efficacy and Dosing

Bronchopulmonary DysplasiaBronchopulmonary Dysplasia Associated Pulmonary Hypertension3 more

Oral L-citrulline supplementation may prevent and/or decrease the severity of chronic lung disease associated with pulmonary hypertension in preterm infants. Since oral L-citrulline supplementation has never been studied in preterm infants before, the side effect profile and appropriate dosing are still unknown. In this pilot study, the investigators will determine the safety profile, efficacy and appropriate dosing of oral L-citrulline in preterm infants. In the future, information from this study will be utilized to conduct a randomized placebo-controlled trial to evaluate the role of L-citrulline supplementation in treating BPD_PH.

sNIPPV Versus NIV-NAVA in Extremely Premature Infants

Premature BirthVentilator Lung; Newborn

The aim of this study is to demonstrate a significant decrease in asynchrony with NIV-NAVA using the Servo n ventilator (Getinge, Sweden), as compared to abdominal triggered (Graseby capsule) synchronized nasal intermittent positive pressure ventilation (sNIPPV) using the Infant Flow CPAP device (Care Fusion, USA). All of the data obtained can be used to develop a large-scale study aimed at reducing the rate of re-intubation in the study population (pilot study). In fact, the re-intubation criteria for extremely premature children are based on clinical criteria (desaturations, apnea, signs of respiratory control) and paraclinical criteria (FiO2, Potential hydrogen (pH), PCO2). The results of this pilot study will help to develop an adapted methodology and to calculate a sample size to compare the 2 modes of NIV to the test on a clinical criterion: the rate of re-intubation after extubation, which is classically high in these patients.

Preterm BirthPremature11 more

Infants in the neonatal intensive care unit (NICU) may be lost due to risks such as being sensitive, frequent exposure to birth complications and being prone to infection. The most common causes of mortality in newborn babies in the world; Complications due to preterm delivery (28%), infections (26%) and perinatal asphyxia (23%) were reported. Respiratory problems are observed in 4-6% of newborns. These problems are also important causes of mortality in the neonatal period. Newborn infants are more likely to have respiratory distress due to difficulties in airway calibration, few collateral airways, flexible chest wall, poor airway stability, and low functional residual capacity.Invasive mechanical ventilation (IMV) is frequently used in the treatment of newborns with respiratory failure. Various ventilation modes and strategies are used to optimize mechanical ventilation and prevent ventilator-induced lung injury. Among the important issues to be considered in newborns connected to mechanical ventilator (MV); Choosing an appropriately sized endotracheal tube to reduce airway resistance and minimize respiratory workload, correct positioning, regular nursing care, chest physiotherapy, sedation-analgesia, and infection prevention are also included.

Early-life MRI Biomarkers of Longer-term Respiratory Morbidity in Infants Born Extremely Preterm...

Lung FunctionBPD - Bronchopulmonary Dysplasia

Bronchopulmonary dysplasia (BPD) is a common, major complication of premature birth, associated with developmental and health consequences that continue into adulthood. Prediction of who will have these problems is challenging using traditional definitions of disease. It is believed that underdevelopment and injury occur in both lung tissue and the blood vessels in the lungs, with a sophisticated interplay between them that contributes to lung disease seen in prematurity. New magnetic resonance imaging (MRI) techniques can delineate tissue structure with unprecedented granularity, assessing lung tissue, blood vessels, and their interplay. The ability to identify, at an early stage, those infants destined for chronic lung disease with greater certainty will be useful in counseling families and critical for the effective introduction of promising new BPD therapies. 319 infants born less than 29 weeks gestation will be recruited from 4 centres, including 5 babies who received stem cell therapy in a clinical trial. Babies will be evaluated at 36 weeks post-conception with lung MRI, oscillometry (lung function), echocardiogram (heart ultrasound), and oscillometry. Lung health will be assessed every 3 months by phone questionnaire and chart review. At 18-21 months post-conception, babies will undergo neurodevelopmental assessment and lung function testing. The investigators will look at how well baseline MRI markers predict subsequent lung health and development, independently and combined with echocardiogram, lung ultrasound, and traditional markers of BPD. The investigators anticipate that these new MRI markers will measure lung health safely and longitudinally in babies born extremely preterm. By identifying predictors of longer-term lung disease, clinicians will be able to allocate resources to babies at the highest risk of severe disease. Further, The investigators envision that MRI will help identify babies who would benefit most from interventions like stem cell therapy and be useful for evaluation of future treatments.
