    Notes: Abstract Newborn infants (21 preterm and 13 term) received dopamine infusions at a low (2.5–3.4 μg/kg per min) and/or high (5–10 μg/kg per min) infusion rate and changes in plasma catecholamines were monitored. The mean baseline values for dopamine, noradrenaline and adrenaline were between 240 and 560, 125 and 144 and 62 and 82 pg/ml, respectively. During low-rate infusion of dopamine, there was a significant increase in plasma dopamine (20–100fold), noradrenaline (three- to five-fold) and adrenaline (threefold). Administration of dopamine at the high rate resulted in an even larger increase in the plasma catecholamines (dopamine, 100–300fold; noradrenaline, seven- to eightfold; adrenaline, four- to sixfold). In a double-log plot, there was a highly significant correlation between the plasma concentrations of dopamine and noradrenaline (r=0.77;P〈0.001). In conclusion, infusion of dopamine in term and preterm newborn infants is accompanied by an enhanced sympatho-adrenal tone which may contribute to the cardiovascular effects of dopamine in these patients.

    Notes: An drei Wärmeaustauschern, dem Rohrbündel-, dem Scheiben- und dem Schraubenrohrwärmeaustauscher aus Diabon-Graphit wurden Wärmedurchgangsmessungen durchgeführt. Die spez. Übertragungsleistungen, ausgedrückt durch die Wärmedurchgangszahlen, liegen bei allen drei Baumustern sehr günstig. Zweck der Untersuchung sollte sein, dem anwendenden Ingenieur ein Bild von der Leistungsfähigkeit und Belastbarkeit einiger Graphit-Wärmeaustauscher aus jüngster Entwicklung zu vermitteln.
