Normal 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 کاملReference 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 کاملA cross-sectional study on reference ranges of normal oral temperatures among students in Singapore.
INTRODUCTION During the 2003 Severe Acute Respiratory Syndrome (SARS) outbreak, all schools in Singapore implemented twice-daily temperature monitoring for students to curtail the spread of the disease. Students were not allowed to attend school if their temperature readings were >37.8 degrees C for students < or =12 years old, or > or =37.5 degrees C for students >12 years old. These values ha...
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...
متن کاملTarget ranges of oxygen saturation in extremely preterm infants.
BACKGROUND Previous studies have suggested that the incidence of retinopathy is lower in preterm infants with exposure to reduced levels of oxygenation than in those exposed to higher levels of oxygenation. However, it is unclear what range of oxygen saturation is appropriate to minimize retinopathy without increasing adverse outcomes. METHODS We performed a randomized trial with a 2-by-2 fac...
