Reference ranges for cardiac dimensions and blood flow velocity in preterm infants.
AIM To establish reference ranges for cardiac dimensions and Doppler measurements in preterm infants. METHODS 79 infants of less than 34 weeks' gestation were examined by echocardiography on days 0, 7, and 28 after birth, to produce a set of reference ranges and to examine changes in these indices over the first month of life. The following dimensions were measured: interventricular septum, l...
متن کاملNormal reference ranges for cardiac valve cross-sectional areas in preterm infants
Objective To establish normal reference ranges for cardiac valve crosssectional areas (CSAs) in preterm infants and their correlation with gestational age, body weight, and chronological age. Materials and Methods In a prospective study, 268 preterm babies fulfilling the criteria for inclusion were examined. Echocardiograms were performed to measure aortic, pulmonary, mitral, and tricuspid va...
متن کاملNormal Value of Left Ventricular End-Systolic Elastance in Infants and Children
Background: In certain conditions, there is a need for a specific and improved measure of cardiac performance. Routine methods for assessing left ventricular (LV) function are based on image-analysis or right heart monitoring which do not allow evaluation of ventriculo-arterial interaction. Chen et al presented a noninvasive method allowing measurement of end-systolic pressure–volume relation ...
متن کاملReference ranges for the linear dimensions of the intracranial ventricles in preterm neonates.
AIMS To establish normal ranges, in preterm infants < 33 weeks' gestation, for measurements of the lateral, third, and fourth ventricles and to assess intra-observer and inter-observer reliability. To assess the effect of head position during scanning on lateral ventricle size. To determine whether sex influences ventricle size. METHODS A prospective study involving infants < 33 weeks' gestat...
متن کاملReference Ranges of Reticulocyte Haemoglobin Content in Preterm and Term Infants: A Retrospective Analysis.
BACKGROUND Despite iron supplementation, some preterm infants develop iron deficiency (ID). The optimal iron status parameter for early detection of ID has yet to be determined. OBJECTIVE To establish reference ranges for reticulocyte haemoglobin content (Ret-He) in preterm and term infants and to identify confounding factors. METHODS Retrospective analyses of Ret-He and complete blood coun...
