Effect of Antenatal Steroids on Haemodynamics in the Normally Grown and Growth Restricted Fetus
The administration of antenatal glucocorticoids to women in preterm labour confers clear and significant benefits on perinatal outcomes, decreasing the incidence of respiratory distress syndrome and intraventricular hemorrhage in preterm babies, thereby reducing rates of mortality and morbidity. However, there is an evolving body of research addressing the non-pulmonary consequences of antenata...
متن کاملGrowth and Flowering Responses of Cut Chrysanthemum Grown under Restricted Root Volume to Irrigation Frequency
Influences of irrigation frequency on the growth and flowering of chrysanthemum grown under restricted root volume were tested. Chrysanthemum cuttings (Chrysanthemum morifolium "Reagan White") were grown in seedling tray which contained coconut peat in volumes of 73 and 140 cm(3). Plants were irrigated with drip irrigation at irrigation frequencies of 4 (266 mL), 6 (400 mL), and 8 (533 mL) time...
متن کاملFractional changes in lung capillary blood volume and oxygen saturation during the cardiac cycle in rabbits.
Changes in local pulmonary capillary blood volume (Vc) and oxygen saturation (S) have been difficult to measure in live animals. By utilizing the differences in absorption of light at two wavelengths (650 and 800 nm), we estimated the fractional change in Vc and S during the course of the cardiac cycle in eight anesthetized, ventilated rabbits at low and high lung volumes. Observations were mad...
متن کاملRegional extravascular density and fractional blood volume of the lung in interstitial disease.
Regional lung density (g lung/ml thoracic volume) and fractional pulmonary blood volume (ml blood/ml thoracic volume) have been measured by positron tomography in 10 patients with interstitial disease. From the measurements regional extravascular lung density (g tissue and interstitial water/ml thoracic volume) was derived, providing a non-invasive measurement of the interstitial reaction. Extr...
متن کاملReduced placental volume and flow in severe growth restricted fetuses
OBJECTIVES To evaluate placental volume and vascular indices in pregnancies with severe fetal growth restriction and determine their correlations to normal reference ranges and Doppler velocimetry results of uterine and umbilical arteries. METHODS Twenty-seven fetuses with estimated weights below the 3rd percentile for gestational age were evaluated. Placental volume and vascular indices, inc...
