7 Clinical Trials for Various Conditions
Investigators want to learn the role of indoor environmental exposures on respiratory symptoms, and, separately, on lung function deficits in school-aged children with bronchopulmonary dysplasia (BPD).
Bronchopulmonary dysplasia (BPD) is a serious lung condition that affects premature newborns. The condition involves abnormal development of lung tissue and is characterized by inflammation and scarring in the lungs. Treatment with inhaled nitric oxide (iNO) may reduce the incidence of BPD and another commonly associated condition called pulmonary hypertension, which is high blood pressure in the vessels carrying blood to the lungs.. This study will determine if early treatment with low-dose iNO reduces the incidence of BPD, pulmonary hypertension, and death in premature newborns.
This multicenter clinical trial tested whether minimal ventilation decreases death or BPD. Infants with birth weight 501g to 1000g and mechanically ventilated before 12 hours were randomly assigned to minimal ventilation (partial pressure of carbon dioxide \[PCO(2)\] target \>52 mm Hg) or routine ventilation (PCO(2) target \<48 mm Hg) and a tapered dexamethasone course or saline placebo for 10 days, using a 2 x 2 factorial design. The primary outcome was death or BPD at 36 weeks' postmenstrual age. Blood gases, ventilator settings, and FiO2 were recorded for 10 days; complications and outcomes were monitored to discharge. The infants' neurodevelopment was evaluated at 18-22 months corrected age.
This observational study was conducted to design and test a physiologic definition for bronchopulmonary dysplasia at 36 weeks of life. Infants were studied in a supine position with the pulse oximeter in position with good signal prior to collecting baseline data. Feedings and medications were given 30 minutes before the evaluation. Baseline data was collected on infant's current oxygen. Then, the infants were weaned to room air for 30 minutes. If saturations remain ≥90%, the infant was considered to have passed the oxygen reduction challenge (to NOT have BPD). The infant should then be placed back in his/her baseline oxygen. If the infant has saturations \<90% for 5 continuous minutes or \<80% for 15 seconds, the infant should be immediately placed back in his/her baseline oxygen, and the infant was considered to have NOT passed the challenge (to have BPD).
This multi-site, randomized trial was conducted to determine the safety and effectiveness of a higher dose of vitamin A and determine if this would increase the rate of survival without bronchopulmonary dysplasia (BPD) and reduce the risk of sepsis. Infants with birth weights from 401-1000g and who were on mechanical ventilation or supplemental oxygen at 24-96 hours of age were enrolled. Subjects were randomized to either the Vitamin A or a control group. Infants in the Vitamin A group were given a dose of 5000 IU (0.1 ml) intramuscularly on Mondays, Wednesdays, and Fridays for four weeks. Control infants received a sham procedure rather than placebo injections.
This study tested whether Neonatal Intensive Care Unit (NICU) teams trained in benchmarking -- comparing care practices between different NICUs to see which practices prevent bronchopulmonary dysplasia (BPD) -- and quality improvement would change practices and improve rates of survival without BPD in inborn neonates with birth weights of \<1250 grams. Benchmarking is a method involving detailed comparisons of processes between similar organizations. For this study, three NRN centers with the lowest rates of BPD have been identified as Benchmark centers. During a 6-month pre-intervention period, details of care practices and management style at these centers were carefully assessed. Based on practices at these Benchmarking sites, we developed a quality improvement program. For this study, 14 other NRN sites were randomized to either implement the benchmarking intervention (intervention sites) or continue with their usual care practices (control sites). After the 1-year intervention period, we compared changes in the rate of survival without BPD at 36 weeks corrected age between the intervention and control sites.
Premature infants have high rates of bronchopulmonary dysplasia (BPD) due to prematurity of the participants' lungs and the need for prolonged respiratory support. These infants are at increased risk for gastroesophageal reflux and aspiration which may exacerbate lung injury. Transpyloric feeds, specifically duodenal feeds, may be used to bypass the stomach and directly feed the duodenum decreasing the amount of gastric reflux contributing to aspiration. Duodenal feeds are equivalent to gastric feeds with regards to nutritional outcomes, and have been shown to decrease events of apnea and bradycardia in premature infants. This study will evaluate the feasibility and safety of duodenal feeds in premature infants. The hypothesis is that duodenal feeds may be safely and successfully performed in premature very low birth weight infants.
