Bedside estimation of whole blood lactate.
A new instrument for the measurement of lactate in biological fluids, the Lactate Analyzer 640, has been evaluated. The method of use recommended by the manufacturer for blood samples was found to be inadequate. A new method of sample preparation for the instrument, based upon immediate haemolysis and fluoridation of blood, has been developed, allowing measurement of whole blood lactate concent...
متن کاملTest-strip method for measuring lactate in whole blood.
We have developed a dry reagent strip system for measuring lactate in whole blood. The test strip contains lactate oxidase (no EC number assigned), horseradish peroxidase (EC 1.11.1.7), and N-ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine. The system is designed to measure with a reflectometer the color that developed in the test strip, although the lactate concentration can be estimated without...
متن کاملSodium lactate as a preservative for whole blood.
argument. Clinical experience of the blood bank in 9000 cases was uniformly favourable. The way is open to replace citrate, at least partially, by lactate. This could be done either maintaining the dilution as we personally prefer, or preparing a more concentrated formula, if dilution is not considered an advantage. A specific action of lactate was not found, but lactate is a good preservative ...
متن کاملBedside estimation of nonaerated lung tissue using blood gas analysis.
OBJECTIVES Studies correlating the arterial partial pressure of oxygen to the fraction of nonaerated lung assessed by CT shunt yielded inconsistent results. We systematically analyzed this relationship and scrutinized key methodological factors that may compromise it. We hypothesized that both physiological shunt and the ratio between PaO2 and the fraction of inspired oxygen enable estimation o...
متن کاملA Simplified Estimation of Lactate in Normal Human Blood
We have been accustomed to estimate the lactate in blood by hemolysis in water, removal of the proteins by the method of Folin and Wu (4), treatment of the filtrate with CuSO4 and Ca(OH)2 according to Van Slyke (ll), and estimation of the lactate in the centrifugate by a modification of the aeration method of Friedemann, Cotonio, and Shaffer (6). There have been suggestions that some of the pre...
