BASE EXCESS AND ORGANIC ACIDÆMIA

Prediction of Respiratory Morbidities in Late Preterm Neonates Using Cord Blood Arterial Lactate and Base Excess

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 significance of base excess ( BEB ) and base excess in the extra cellular fluid compartment ( BEEcf ) July 2010

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...

The accuracy of calculated base excess in blood.

Most equations used for calculation of the base excess (BE, mmol/l) in human blood are based on the fundamental equation derived by Siggaard-Andersen and called the Van Slyke equation: BE = Z x [[cHCO3-(P) - C7.4 HCO3-(P)] + beta x (pH -7.4)]. In simple approximation, where Z is a constant which depends only on total hemoglobin concentration (cHb, g/dl) in blood, three equations were tested: th...
