Exercise induces increased circulating levels of a number of cytokines. Thus, increased plasma levels of tumour necrosis factor (TNF)-alpha, interleukin (IL-1) beta, IL-1 receptor antagonist (IL-1ra), TNF-receptors (TNF-R), IL-10, IL-8, and macrophage inflammatory protein (MIP)-1 are found after strenuous exercise. The concentration of IL-6 increases up to(More)
In humans, the plasma interleukin 6 (IL-6) concentration increases dramatically during low-intensity exercise. Measurements across the working limb indicate that skeletal muscle is the source of IL-6 production. To determine whether energy availability influences the regulation of IL-6 expression during prolonged exercise, six male subjects completed two(More)
Das Management des schwierigen Atemweges und die Aufrechterhaltung der Oxygenation sind die zentralen Aufgaben des Anästhesisten. Respiratorische Probleme stellen nach wie vor die häufigste Einzelursache für rein anästhesiebedingte Zwischenfälle mit schlechtem Outcome dar.Algorithmen sind stufenartige Verfahrensweisen, die aus einer Vielzahl von(More)
BACKGROUND The laryngeal mask airway ProSeal (PLMA), a new laryngeal mask device, was compared with the laryngeal mask airway Classic (LMA) with respect to: (1) insertion success rates and times; (2) efficacy of seal; (3) fiberoptically determined anatomic position; (4) orogastric tube insertion success rates and times; (5) total intraoperative(More)
Ziele der Beatmung eines ungeschützten Atemweges sind Oxygenierung und Kohlendioxidelimination des Patienten. Dies kann mit Techniken, wie der Mund-zu-Mund- oder besser der Maskenbeatmung, erreicht werden. Zur Atemwegssicherung ist die Intubation der Goldstandard; allerdings hängt hier der Erfolg, v. a. im Notfall, von der initialen Ausbildung und einem(More)
We have compared four tests for assessing airway sealing pressure with the laryngeal mask airway (LMA) to test the hypothesis that airway sealing pressure and inter-observer reliability differ between tests. We studied 80 paralysed, anaesthetized adult patients. Four different airway sealing pressure tests were performed in random order on each patient by(More)
Carefully categorized postmortem human brains are crucial for research. The lack of generally accepted methods for processing human postmortem brains for research persists. Thus, brain banking is essential; however, it cannot be achieved at the cost of the teaching mission of the academic institution by routing brains away from residency programs,(More)
UNLABELLED In this randomized, controlled, cross-over study, we measured the pressures exerted by the standard laryngeal mask airway (LMA) and the intubating laryngeal mask airway (ILM) against the cervical vertebrae during insertion, intubation, and maneuvers commonly used to facilitate intubation. We also assessed the effect of these pressures on cervical(More)
BACKGROUND This study compares four tests for assessing oropharyngeal leak pressure with the laryngeal mask airway (LMA). We tested the hypothesis that the oropharyngeal leak pressure and interobserver reliability differs between tests. METHODS Eighty paralysed anaesthetized paediatric patients (weight 10-30 kg) were studied with the intracuff pressure(More)
BACKGROUND We compared three techniques for insertion of the laryngeal mask airway ProSeal (PLMA) in patients with simulated difficult laryngoscopy using a rigid neck collar. METHODS Ninety-nine anesthetized healthy female patients aged 19-68 yr were randomly allocated for PLMA insertion using the digital, introducer tool (IT) or guided techniques.(More)
