Active clinical trials for "Bronchopulmonary Dysplasia"

This is a prospective, longitudinal observational study to provide data regarding the natural course of hypercapnia in premature infants with bronchopulmonary dysplasia using both available blood pCO2 and measured capnography, as well as relate the degree and trend of hypercapnia to later respiratory outcomes.

The chances of survival in premature babies, especially in babies born under 28 weeks, have increased in recent years, and comorbidities also increase. Bronchopulmonary dysplasia (BPD), one of the premature problems, is one of them. After a while, babies with heavy BPD are discharged with the support of a home-type mechanical ventilator by opening a tracheostomy. Tracheostomy procedure is performed by specialist doctors of otolaryngology under general anesthesia in the operating room conditions in newborns. Complications of this procedure such as bleeding, skin necrosis, decanulation, trachea laceration and infection in the early period can be seen. In the long term, in addition to complications such as formation of tracheal granulation tissue, ulceration, laceration due to the procedure, babies with tracheostomy may develop nutrition and speech problems and neurodevelopmental problems. In the literature, there is no comprehensive clinical follow-up study involving early and late clinical results related to newborns undergoing tracheostomy. In this study, early and late follow-up results (indications, anthropometric measurements, mechanical ventilation and oxygen deposition times, complications, tracheostomy closure times, tracheostomy closure times, neurodevelopmental patients in the Neonatal Intensive Care Unit of Hacettepe University Ihsan Dogramaci Children's Hospital. results, accompanying other comorbidities, etc.).

Despite considerable obstetric and neonatal advances in the care of very low birth weight (VLBW) neonates, bronchopulmonary dysplasia (BPD) continues to occur among 20 to 40% of surviving infants, and new ways for combatting this disease must be found. BPD appears to result from arrested lung development, but its etiology has not yet been fully established. Besides the role of the exposure of the immature lung to injurious factors in the development of BPD, a genetic susceptibility for BPD in preterm infants was recently evidenced. Taking advantage of new genomic technologies, the objective of the investigators' project is to identify predisposing human genetic variants through: a genome-wide association (GWA) study in VLBW neonates, a candidate-gene association study, including selection of single nucleotide polymorphisms (SNPs) found in (a) and functional studies of any SNP found to be convincingly associated with BPD in (a) and (b).
