Measurement of plasma volume in neonates.
There is no reliable and safe method for measuring plasma volume in ill newborn infants. We describe an adaptation of the dye dilution technique using indocyanine green as the plasma label, which can be used in the sickest and smallest of infants with the minimum of disturbance. To avoid the need to take large volumes of blood from the infant, samples were diluted 1:1 with distilled water and p...
متن کاملUltrasound Measurement of Kidney Dimensions in Premature Neonates
Background Ultrasonography is a non-invasive and accurate diagnostic method to evaluate urinary system and its anomalies in the neonates. Kidney sonographic measurement can be used as an alternative method to estimate gestational age. The aim of this study was to measure kidney size in preterm neonates and to provide a guide reference for gestational age. <...
متن کاملThe regulation and measurement of plasma volume in heart failure.
Plasma volume, the intravascular portion of the extracellular fluid volume, can be measured using standard dilution techniques with radiolabeled tracer molecules. In healthy persons, plasma volume remains relatively constant as a result of tight regulation by the complex interaction between neurohormonal systems involved in sodium and water homeostasis. Although chronic heart failure (CHF) is c...
متن کاملMeasurement of right ventricular volume in healthy term and preterm neonates.
BACKGROUND Pulmonary hypertension is associated with worse perinatal outcomes in infants with respiratory disorders. In such infants right ventricular dysfunction may result in poor pulmonary blood flow. OBJECTIVE To evaluate the practicability and repeatability of echocardiographic measurements of right ventricular volume in healthy term and preterm neonates, and to follow changes in right v...
متن کاملMeasurement of plasma volume using fluorescent silica-based nanoparticles.
Plasma volume (PV) is an important determinant of cardiovascular function and organ perfusion, and it is the target of infusion and diuretic therapies in daily clinical practice. Despite its fundamental importance PV is not commonly measured because available methods of tracer dilution are reliant on dye substances that suffer from numerous drawbacks including binding plasma proteins, spectral ...
