Assessment of exhaled gases in ventilated preterm infants.

چکیده
Hydrogen peroxide (H2O2) production in exhaled air was measured in ventilated preterm newborns at 5, 24 and 48 hours after delivery, using originally designed method of exhaled breath condensate (EBC) collection. H2O2 production in expired gas was 812+/-34 pmol/20 min during the first measurement and then declined to 389+/-21 at 24 hours and 259+/-26 pmol/20 min at 48 hours.

Breath pentane as a marker for lipid peroxidation and adverse outcome in preterm infants.
AIM To test the hypothesis that complications of neonatal intensive care are related to increased oxygen derived free radical activity, using breath pentane as a marker of lipid peroxidation. METHODS Exhaled breath was collected daily from 57 ventilated preterm infants and pentane concentration measured by gas chromatography. RESULTS High peak pentane exhalation was significantly associated...
متن کاملConservative Management in a Ventilated Preterm Neonate with Pneumopericardium, Pleural Effusion, and Pulmonary Collapse: A Case Report
Background: Neonatal pneumopericardium (PPC) is a rare clinical condition usually associated with other air leak syndromes. It increases morbidity and mortality due to cardiac tamponade. Case report: A preterm male neonate weighing 1260 g was born with the gestational age of 28 weeks. Cardiopulmonary resuscitation was routinely performed without any medical therapy. The newborn was transferred ...
متن کاملEffect of Mechanical Ventilation on Intestinal Permeability in Preterm Infants: A Retrospective Cohort Study
Mechanical ventilation (MV) and ventilator strategies can induce or aggravate lung injury and may contribute to the development of distant organ failure, including the gastrointestinal tract. A retrospective cohort study was performed among 61 preterm infants, with a gestational age of 25-36 weeks, admitted at a neonatal intensive care unit. Intestinal permeability was measured by the sugar abs...
متن کاملApoptosis and proliferation in lungs of ventilated and oxygen-treated preterm infants.
Apoptosis and proliferation and the effect of exogenous surfactant on these processes were investigated in the lungs of mechanically ventilated/oxygen-treated preterm infants with respiratory distress syndrome and stillborn foetuses. Apoptotic and proliferation indices were determined in lung tissue sections from 27 ventilated/oxygen-treated preterm infants and 29 stillborn foetuses. The effect...
متن کاملThe impacts of prone position on the blood oxygen saturations and heart rates of preterm infants under the mechanical ventilation
Background: The methods of baby's position are an important critical factor in ventilation and oxygenation of tissues. Although the prone position as one of the recommended position has beneficial effect on the development of premature infants, little research has been done. Methods: In a clinical trial among mechanically ventilated infants, hospitalized in the neonatal intensive care units (N...
