Suitability of non-glucose-carbohydrates for parenteral nutrition
Postoperative parenteral nutrition can only be optimally effective if the characteristics of post-traumatic metabolism are taken into account. Two main possibilities are discussed for the carbohydrate component of parenteral nutrition during this phase: glucose with high doses of insulin or non-glucose carbohydrates (sugar substitutes) possibly in a suitable combination with glucose. The risks as well as the technical and organisational problems involved in the use of them are discussed and the authors prefer the second of the two alternatives. Possible side effects of non-glucose carbohydrates are pointed out and it is shown how these can be avoided by observing dose guidelines. So far a c…
Numerical dating of the Eckfeld maar fossil site, Eifel, Germany: a calibration mark for the Eocene time scale.
Sediments of the Eckfeld maar (Eifel, Germany) bear a well-preserved Eocene fauna and flora. Biostratigraphically, Eckfeld corresponds to the Middle Eocene mammal reference level MP (Mammals Paleogene) 13 of the ELMA (European Land Mammal Age) Geiseltalian. In the maar crater, basalt fragments were drilled, representing explosion crater eruption products. By 40Ar/39Ar dating of the basalt, for the first time a direct numerical calibration mark for an Eocene European mammal locality has been established. The Eckfeld basalt inverse isochron date of 44.3 +/- 0.4 Ma suggests an age for the Geiseltalian/Robiacian boundary at 44 Ma and, together with the 1995 time scale of Berggren et al., a time…
Die Vorteile von Xylit gegenüber Glucose als Energiedonator im Rahmen der frühen postoperativen parenteralen Nährstoffzufuhr
24 stoffwechselgesunde Patienten, die sich einer Magenoperation unterziehen musten, wurden nach einer 5tagigen praoperativen Vorbereitungszeit 5 Tage lang postoperativ hypokalorisch total parenteral ernahrt. Kollektiv I, n=13; erhielt 0,11 g Xylit/kg KG · Std.; Kollektiv II, n=11; erhielt 0,11 g Glucose/kg KG · Std. Beide Kollektive erhielten 1,71 g L-kristalline Aminosauren/kg KG · die. Wahrend der gesamten postoperativen Phase konnten bei Kollektiv II signifikant hohere Glucose- und Insulinspiegel im Serum gemessen werden. Der postoperativ stark erhohte Insulinspiegel bei Kollektiv II fuhrte zu signifikant niedrigeren Werten an freien Fettsauren, Acetacetat, Β-Hydroxybutyrat- und verzweig…
