Filter by:The purpose of this study is to examine the influence medical or surgical treatment for patent ductus arteriosus in preterm infants on cerebral and renal tissue oxygenation and on cardiac output.
Oseltamivir dosing in infants < 3 months of age is based on a single pharmacokinetic study in 20 infants from a single center. This dataset is limited by a lack of robustness, because only 1 sample was collected from each participant. The investigators obtained two blood samples each from infants receiving oseltamivir after obtaining informed consent from the infant's parents. The investigators propose to analyze the blood samples to determine the amount of oseltamivir in the infant's blood. Measurement of these values will increase the understanding of the absorption and elimination of oseltamivir in preterm and term infants, and improve our ability to provide the correct doses to this high risk population.
The purpose of the study is to compare early versus late initiation of enteral feeding in premature growth restricted babies below the gestational age of 35 weeks born to mothers with prenatal absent or reversal of end diastolic flow in the umbilical artery. Normally the blood flow from the mother to the baby brings all the nutrients required for growth and the very vital oxygen required for survival. These deprived babies with poor blood flow adapt to the not so conducive uterine environment by certain adjustments in blood supply to internal organs. This permits the best possible blood flow to brain heart etc., which are the vital organs and whose adequate functioning is required for survival. As a consequence, the gut (intestines) gets poor blood supply and hence its appropriate functioning may be jeopardized. Such 'premature growth restricted' babies are at increased risk of further growth faltering if not fed adequately as also to a condition called 'Necrotising enterocolitis' if fed liberally like other healthy neonates, characterized by abdominal distension, blood in stools and inability to feed for longer durations thereby further affecting growth. In the past such babies (after birth) were not fed for days together which compromised their growth even further. It is not clear whether continuing to withhold feeds for prolonged duration will prevent NEC but lead to growth faltering and initiating feeds early will potentiate NEC with further compromised growth and increased morbidity. There are no randomized trials on feeding strategies in this group of neonates and hence the investigators planned to carry out this study on comparison of early versus delayed initiation of feeding in preterm SGA infants with AREDF.
The investigators examined the effect of different levels of docosahexaenoic aicd (a long chain polyunsaturated fatty acid) intake on the fatty acid composition of plasma and erythrocyte phospholipids and on the maturity of visually evoked potentials in preterm infants. As a secondary outcome the conversion of linoleic acid and alpha linolenic acid into their corresponding long chain polyunsaturated fatty acids was studied. Preterm infants were randomized in a double-blind fashion to one of three formulas containing different amounts of docosahexaenoic acid during the first two weeks of postnatal life. A control group received human milk. Blood samples were collected at study entry and 14 and 28 days thereafter. Uniformly 13C-labeled linoleic acid and alpha linolenic acid were applied orally before blood sampling at day 28. At postconceptional ages 48 weeks and 56 weeks visually evoked potentials were recorded.
Purpose of the study: 1. To evaluate the effect of prematurity on renal function in 5 years old children 2. To compare former premature children treated by ibuprofen in the neonatal period to controls
