Decline in lung liquid volume before labor in fetal lambs.
The volume of liquid in the fetal lung depends on the amount of liquid secreted across the pulmonary epithelium and the amount flowing through the trachea. Lung liquid volume (V1) and secretion rate Vs) were determined using an indicator-dilution technique, while tracheal flow rate (Vtr) was measured simultaneously with a bubble flowmeter. Least-squares regression analysis showed that in 10 chr...
متن کاملFetal Lambs
Morphologic analyses of lungs from infants who died of severe aortic stenosis shortly after birth have shown increased pulmonary vascular smooth muscle and an increased number of pulmonary resistance vessels. These findings have been thought to be caused by in utero pulmonary venous, pulmonary arterial or right ventricular hypertension. To study this problem in the fetus, we created aortic sten...
متن کاملInhaled nitric oxide effects on lung structure and function in chronically ventilated preterm lambs.
RATIONALE Inhaled nitric oxide (iNO) can reverse neonatal pulmonary hypertension and bronchoconstriction and reduce proliferation of cultured arterial and airway smooth muscle cells. OBJECTIVES To see if continuous iNO from birth might reduce pulmonary vascular and respiratory tract resistance (PVR, RE) and attenuate growth of arterial and airway smooth muscle in preterm lambs with chronic lu...
متن کاملSimplified lung ultrasound protocol shows excellent prediction of extravascular lung water in ventilated intensive care patients
INTRODUCTION Ultrasound of the lung and quantification of B lines was recently introduced as a novel tool to detect overhydration. In the present study, we aimed to evaluate a four-region protocol of lung ultrasound to determine the pulmonary fluid status in ventilated patients in the intensive care unit. METHODS Fifty patients underwent both lung ultrasound and transpulmonary thermodilution ...
