NCT00521625
PALIVE 1 is an observational multicenter study on mechanical ventilation strategies used in children with an acute lung injury (ALI). The objective of the study is to describe mechanical ventilation strategies in children with an ALI. Our hypothesis is that daily clinical practice is heterogenous among pediatric intensivists as few pediatric data exists on optimal mechanical ventilation strategies in this group of patients. Furthermore, different strategies may affect patient outcome.
NCT00006058
OBJECTIVES: I. Create a clinical sample bank of neonates with lung disease to test hypotheses regarding the pathogenesis of bronchopulmonary dysplasia (BPD). II. Determine whether a developmental deficiency of surfactant protein B (SP-B) contributes to the occurrence of respiratory distress and BPD in these patients. III. Study metabolic abnormalities associated with inherited deficiency of SP-B in these patients. IV. Determine whether plasma nitrotyrosine levels, a marker of peroxynitrite mediated oxidant stress, are elevated in premature infants who develop BPD. V. Measure the temporal changes in critical components of the inflammatory process (cell composition, inducible nitric oxide synthase, hyaluronan (HA), receptor for HA mediated mobility, and selected cytokines) in bronchoalveolar lavage, blood, and urine samples obtained from these patients, and to correlate these changes with their clinical course. VI. Examine changes in the insulin-like growth factor axis that occur in the lungs of infants with respiratory distress syndrome (RDS) and BPD. VII. Determine the relationship between degradation of elastin and the clinical course of BPD. VIII. Determine whether the normal fall in plasma endothelin-1 concentrations after birth are delayed in infants with RDS and BPD.
NCT00318331
Glutamine is an amino acid which is rapidly depleted in critical illness. It is used as energy by cells that line the gut, vital for immune system function, and works as an anti-oxidant. Glutamine supplementation has been shown to improve outcomes in ICU patients. We hypothesize that critically ill patients given extra glutamine will have less of an inflammatory response and therefore better outcomes than patients not given extra glutamine. Our study randomizes patients to tube feeding with OR without extra glutamine to see if it affects patient outcomes as well as markers of inflammation.
