Zielkriterien des Qualitätsvergleichs von Neurolept- (NLA), balancierter- (BAL)- und intravenöser (IVA) Anästhesie waren Narkosesicherheit und Patientenwohlbefinden. Anhand des Zwischenfall-, Ereignis- und Komplikationsschlüssels (ZEK) der Deutschen Gesellschaft für Anästhesiologie und Intensivmedizin (DGAI) wurde ein seltener ZEK-Eintritt als Ausdruck(More)
BACKGROUND Blood donation is a safe human model for acute blood loss. This study investigated associated changes in regional cerebral oxygenation and cerebral blood volume (CBV) by near-infrared spectroscopy (NIRS). STUDY DESIGN AND METHODS Fifty healthy blood donors donated 450 mL of whole blood within 4 to 9 minutes. Changes in regional cerebral oxygen(More)
The recent discovery of chitin within skeletons of numerous marine and freshwater sponges (Porifera) stimulates further experiments to identify this structural aminopolysaccharide in new species of these aquatical animals. Aplysina fistularis (Verongida: Demospongiae: Porifera) is well known to produce biologically active bromotyrosines. Here, we present a(More)
Bei 1318 Patienten wurden Narkosesicherheit, Verträglichkeit und Vigilanz nach Neurolept – (NLA), balancierter – (BAL) – und intravenöser Propofolanästhesie (IVA) anhand von DGAI-ZEKListe und -Fragebogen sowie spezieller Vigilanztests analysiert. Prämedikation und Narkoseführung waren standardisiert. Als Ausdruck unterschiedlicher Narkosesicherheit wurden(More)
Pulsed laser deposited Au-BFO-Pt/Ti/Sapphire MIM structures offer excellent bipolar resistive switching performance, including electroforming free, long retention time at 358 K, and highly stable endurance. Here we develop a model on modifiable Schottky barrier heights and elucidate the physical origin underlying resistive switching in BiFeO3 memristors(More)
Resistant strains of Klebsiella pneumoniae were found in increasing frequency as a cause of nosocomial infection in an intensive care unit between July and October 1990. The isolated strains had an almost identical biochemical profile, showed a similar pattern of antibiotic resistance, and produced type SHV2-broad-spectrum betalactamase. Thus, it was(More)

The safety and tolerance of neuroleptanaesthesia (NLA), balanced anaesthesia (BAL), and intravenous anaesthesia with propofol (IVA) were analysed for the first time in a prospective, randomised clinical trial. METHODS. In all, 1318 surgical patients received either NLA, BAL, or IVA. Patients who had regional anaesthesia, were aged under 18 years, or were(More)
The choice of appropriate anaesthesia in a more or less seriously ill patient requires detailed information on the risk and tolerance of each specific anaesthetic regimen. The objective of this prospective, randomised clinical trial was to test the hypothesis that three regimens of general anaesthesia--neurolept-(NLA), balanced (BAL), and intravenous(More)
The disinfection of bacteria by thermally excited pyroelectric materials in aqueous environments provides opportunities for the development of new means of sanitization. However, little is known about the formation of reactive oxygen species (ROS) at the surface of the thermally excited pyroelectric materials. To investigate the pyroelectrically driven ROS(More)
