The significance of base excess ( BEB ) and base excess in the extra cellular fluid compartment ( BEEcf ) July 2010
نویسنده
چکیده
Independence is achieved by using the extended extracellular fluid (Ecf) for dilution of hemoglobin (cHbB), reducing cHbB to cHbB / 3 (in the fetus to 1/4). Correction of ctHB from the normally low fetal oxygen saturation by reoxygenation of Hb increases ctHB resulting in four different variables: ctHB,act (= BEB), ctHEcf,act (Standard BE), ctHB,ox. and ctHEcf,ox. The question is which variable is most appropriate for perinatal acid-base studies?

The Effect of the Type of Hemodialysis Buffer on the QTc Interval in Patients on Chronic Hemodialysis
Background: Identifying the sources of variation in QTc measurements is important for preventing arrhythmias during and after hemodialysis. The present study was designed to determine the correlation between the type of hemodialysis buffer and the changes in QTc interval in patients on chronic hemodialysis. Methods: Fifty-nine patients on chronic hemodialysis who referred in winter 2007 to hemo...

Background: Late preterm neonates may have the external appearance and behavior similar to their counterparts.However, they are susceptible to various neonatal morbidities , due to their physiological and metabolical immaturity.To assess the correlation between cord blood arterial lactate levels and base excess with the development ofrespiratory distress in late preterm neonat...

The aim of this study was to investigate the effects of Trypanosoma evansi infections on arterial blood gases of experimentally infected rats. Two groups with eight animals each were used; group A (uninfected) and group B (infected). Infected animals were daily monitored through blood smears that showed high parasitemia with 30 trypanosomes per field (1000×) on average, 5 days post-infection (P...
متن کاملLocalization and Study of Histochemical Effects
A high capacity for accumulation of Mn was reported for sunflower plants. Localization of excess Mn is therefore of special interest for understanding metal tolerance mechanisms in this species. In this study, structural and histochemical alterations caused by Mn accumulation in leaves were investigated in sunflower (Helianthus annuus L. cv. Azar-ghol) plants grown in nutrient solution. In the ...
