    Notes: Abstract In ten piglets (body weight 8.2–11.6 kg), acid base, electrolyte and anion gap changes were investigated during almost total plasma replacement with hydroxyethyl starch (HES) and modified fluid gelatin (GEL) in saline solution using a cell saver autotransfusion technique. During the study, there were only moderate acid base changes, but marked disturbances in anion balance. At study end, the mean chloride concentration was significantly higher (mmol/l: normal values 97–108, HES 116 ± 1.5, GEL 108 ± 1.1, p 〈 0.01) and the mean anion gap was significantly lower in the HES group in comparison to the GEL group (mmol/l: normal values 5–14, HES 3 ± 1.7, GEL 11.9 ± 0.9, p 〈 0.01). It is concluded that plasma replacement with electroneutral HES, but not with negatively charged GEL, can lower the anion gap irrespective of the underlying disease. This can be misleading when the anion gap is used for differential diagnosis of metabolic acidosis in patients after large volume infusion of synthetic colloids.

    Evaluation of noninvasive determinants for capillary leakage syndrome in septic shock patients (2000)

    Notes: Abstract. Objective: Capillary leakage syndrome (CLS) is a frequent complication in sepsis, characterized by loss of intravasal fluids leading to generalized edema and hemodynamic instability despite massive fluid therapy. In spite of its importance no standardized diagnostic criteria are available for CLS. Design: Prospective clinical study. Setting: 1800-bed university hospital Patients: Six septic shock patients with CLS were compared to six control patients. Measurements and results: CLS was clinically determined by generalized edema, positive fluid balance, and weight gain. Plasma volume was measured by indocyanine green, red blood cell volume by chromium-51 labeled erythrocytes, and colloid osmotic pressure before and 90 min after the administration of 300 ml 20% albumin. Extracellular water (ECW) was measured using the inulin distribution volume and bioelectrical impedance analysis. Red blood cells averaged 20.2±1.0 ml/kg body weight in CLS patients and 23.3±4.1 in controls. ECW was higher in CLS patients than in controls (40.0±6.9 vs. 21.7±3.7 l; p〈0.05). ECW of inulin was correlated with that measured by bioelectrical impedance analysis (r=0.74, p〈0.01). The increase in colloid osmotic pressure over the 90 min was less in CLS patients than in controls (1.1±0.3 vs. 2.8±1.3 mmHg; p〈0.05). Conclusion: These results suggest that measurements of an increased ECW using bioelectrical impedance analysis combined with a different response of colloid osmotic pressure to administration of albumin can discriminate noninvasively between patients with and those without CLS.

    Hyperfine structure and $$\user1{g} $$ factor measurements on Ba+ and Eu+ isotopes (2000)

    Notes: Abstract Paul and Penning ion traps have been used to determine hyperfine structure coupling constants as well as nuclear $$\user1{g} $$ factors of Ba+ ions with great precision. Attempts are under way to measure both quantities for a long chain of Eu isotopes in order to determine differential hyperfine anomalies for a better understanding of the Bohr–Weisskopf effect.

    The reactive behaviour of the BCL3/H2/steel system (1983)

    Notes: For the description of reactions between solids and gases it is important to investigate the compositional changes in the surface of the solid as a function of temperature and reaction time. Conventional methods of surface analysis cannot be applied in such investigations under atmospheric pressure. We have used the techniques of thermal analysis by emission spectrography (TESG) and of X-ray photoelectron spectroscopy (ESCA). Work with aggressive gases under atmospheric pressure was done in a special reactor, connected by a vacuum-lock directly to the ESCA spectrometer. Thus we have been able to establish characteristic reaction temperatures in the BCl3/H2/steel system and to assign them to certain surface changes. From that a model for the initial phase of the formation of the boride layer on a plain carbon steel has been derived.
