Die Definitionen der Schockformen
2001
Der hypovolamische Schock ist ein Zustand unzureichender Durchblutung vitaler Organe mit konsekutivem Missverhaltnis von Sauerstoff-Angebot und -Verbrauch infolge intravasalen Volumenmangels mit kritisch verminderter kardialer Vorlast; er wird in vier spezielle Formen unterteilt (hamorrhagischer Schock, hypovolamischer Schock im engeren Sinne, traumatisch-hamorrhagischer Schock und traumatisch-hypovolamischer Schock). Der kardiogene Schock ist durch eine primare, kritische Verminderung der kardialen Pumpleistung mit konsekutiver inadaquater Sauerstoff-Versorgung der Organe bedingt. Der anaphylaktische Schock ist eine akute Verteilungstorung des Blutvolumens im Sinn des distributiven Schocks…
Reduced Apo-Fumarate Nitrate Reductase Regulator (ApoFNR) as the Major Form of FNR in Aerobically Growing Escherichia coli▿
2008
ABSTRACT Under anoxic conditions, the Escherichia coli oxygen sensor FNR (fumarate nitrate reductase regulator) is in the active state and contains a [4Fe-4S] cluster. Oxygen converts [4Fe-4S]FNR to inactive [2Fe-2S]FNR. After prolonged exposure to air in vitro, apoFNR lacking a Fe-S cluster is formed. ApoFNR can be differentiated from Fe-S-containing forms by the accessibility of the five Cys thiol residues, four of which serve as ligands for the Fe-S cluster. The presence of apoFNR in aerobically and anaerobically grown E. coli was analyzed in situ using thiol reagents. In anaerobically and aerobically grown cells, the membrane-permeable monobromobimane labeled one to two and four Cys res…
The Association of Intraoperative driving pressure with postoperative pulmonary complications in open versus closed abdominal surgery patients – a po…
2021
Abstract Background It is uncertain whether the association of the intraoperative driving pressure (ΔP) with postoperative pulmonary complications (PPCs) depends on the surgical approach during abdominal surgery. Our primary objective was to determine and compare the association of time–weighted average ΔP (ΔPTW) with PPCs. We also tested the association of ΔPTW with intraoperative adverse events. Methods Posthoc retrospective propensity score–weighted cohort analysis of patients undergoing open or closed abdominal surgery in the ‘Local ASsessment of Ventilatory management during General Anaesthesia for Surgery’ (LAS VEGAS) study, that included patients in 146 hospitals across 29 countries.…
