RETRACTED ARTICLE: Volume replacement with HES 130/0.4 may reduce the inflammatory response in patients undergoing major abdominal surgery
2003
Objectif : Verifier les effets du remplissage intravasculaire sur la reaction inflammatoire pendant une intervention chirurgicale majeure. Methode : Trente-six patients devant subir une intervention abdominale reglee ont ete repartis au hasard et ont recu soit de l'hydroxyethylamidon a 6 % (poids moleculaire moyen de 130 000 Dalton, degre de substitution de 0,4 ; n = 18, groupe HEA), soit une solution de Ringer-lactate (groupe RL ; n = 18) comme remplissage intravasculaire. Les liquides ont ete administres avant l'operation et, pendant 48 h a l'unite des soins intensifs. Le remplissage vasculaire dependait de parametres physiologiques. Les concentrations seriques d'interleukine (IL-6, IL-8 …
Forderungen und Erwartungen an einen optimalen Volumenersatz
2005
A volume replacement should compensate a reduction in the intravascular volume and counteract a hypovolemia so that hemodynamics and vital functions can be maintained. For this therapy, a physiologically-based solution comprising both osmotically and colloid osmotically active components should be administered. A consensus is proposed for this purpose which takes into consideration the following aspects: The optimum colloid, the questionable use of albumin, the physiological electrolyte pattern encompassing sodium, potassium, chloride and phosphate and their contributions to osmolality, an eventual addition of glucose, the physiological acid-base status with bicarbonate or alternately with …
Prediction of dilutional acidosis based on the revised classical dilution concept for bicarbonate
2004
Due to the controversy surrounding the term dilutional acidosis, the classical dilution concept for bicarbonate has been rigorously revised for the prediction of pH, actual bicarbonate concentration, and base excess. In the algorithms derived for buffer solutions, blood, and whole body (1-, 2-, and 3-fluid compartment), only bicarbonate is considered. On dilution at constant Pco2, the final concentration of bicarbonate is the sum in terms of pH, due to the following processes: dilution, formation from chemical reaction with the nonbicarbonate buffers phosphate, hemoglobin, and plasma proteins, and transfer from erythrocytes and interstitial fluid to plasma. At constant Pco2, the level of c…
Blood Volume Substitutes in Emergency Care
1985
Volume substitutes for restoring circulating blood volume are eminently important for emergency care. In addition to side effects, the intravascular volume effect immediately after infusion and the duration of this volume effect are determining factors for the selection of volume replacement solutions available on the market today. Therefore, we controlled the intravascular volume effect of 16 test solutions, immediately as well as 90 and 240 min after the end of infusion.
