Acute emergency care and airway management of caustic ingestion in adultsStruck, Manuel F., Beilicke, André, Hoffmeister, Albrecht, Gockel, Ines, Gries, André, Wrigge, Hermann, Bernhard, Michael 20 June 2016 (has links) (PDF)
Background: Caustic ingestions are rare but potentially life-threatening events requiring multidisciplinary emergency approaches. Although particularly respiratory functions may be impaired after caustic ingestions, studies involving acute emergency care are scarce. The goal of this study was to explore acute emergency care with respect to airway management and emergency department (ED) infrastructures. Methods: We retrospectively evaluated adult patients after caustic ingestions admitted to our university hospital over a 10-year period (2005–2014). Prognostic analysis included age, morbidity, ingested agent, airway management, interventions (endoscopy findings, computed tomography (CT), surgical procedures), intensive care unit (ICU) admission, length of stay in hospital and hospital mortality. Results: Twenty-eight patients with caustic ingestions were included in the analysis of which 18 (64 %) had suicidal intentions. Ingested agents were caustic alkalis (n = 22; 79 %) and acids (n = 6; 21 %). ICU admission was required in 20 patients (71 %). Fourteen patients (50 %) underwent tracheal intubation and mechanical ventilation, of which 3
(21 %) presented with difficult airways. Seven patients (25 %) underwent tracheotomy including one requiring awake tracheotomy due to progressive upper airway obstruction. Esophagogastroduodenoscopy (EGD) was performed in 21 patients (75 %) and 11 (39 %) underwent CT examination. Five patients (18 %) required emergency surgery with a mortality of 60 %. Overall hospital mortality was 18 % whereas the need for tracheal intubation (P = 0.012), CT-diagnostic (P = 0.001), higher EGD score (P = 0.006), tracheotomy (P = 0.048), and surgical interventions (P = 0.005) were significantly associated with mortality. Conclusions: Caustic ingestions in adult patients require an ED infrastructure providing 24/7-availability of expertise in establishing emergent airway safety, endoscopic examination (EGD and bronchoscopy), and CT diagnostic, intensive care
and emergency esophageal surgery. We recommend that - even in patients with apparently stable clinical conditions - careful monitoring of respiratory functions should be considered as long as diagnostic work-up is completed.

Ein Beitrag zum Toxnetz-Explorer: Der Magen-Darm-TraktKeller, Simone Miriam 02 February 2023 (has links)
Die vorliegende Abschlussarbeit „Der Magen-Darm-Trakt: Ein Beitrag zum Toxnetz-Explorer“, wurde von Frau Dr. Simone Miriam Keller im Rahmen des Postgradualstudiums Toxikologie und Umweltschutz der Universität Leipzig angefertigt. In der eingereichten Arbeit werden allgemeine Strukturen des Magen-Darm-Trakts sowie die einzelnen Organe anatomisch beschrieben. Es werden die Funktionen und Aufgaben der Organe des Magen-Darm-Trakts bei der Absorption, Metabolisierung und Ausscheidung erläutert sowie die Metabolisierung von Fremdstoffen wie Arzneimittel und toxische Bestandteile von Nahrungsmitteln, am Beispiel des Mykotoxins Patulin, beschrieben. Die Arbeit dient als Grundlage zur Erstellung eines Toxnetz-Explorer Kapitels zum Thema Magen-Darm-Trakt.

Chemistry of polynuclear transition-metal complexes in ionic liquidsAhmed, Ejaz, Ruck, Michael 02 April 2014 (has links) (PDF)
Transition-metal chemistry in ionic liquids (IL) has achieved intrinsic fascination in the last few years. The use of an IL as environmental friendly solvent, offers many advantages over traditional materials synthesis methods. The change from molecular to ionic reaction media leads to new types of materials being accessible. Room-temperature IL have been found to be excellent media for stabilising transition-metal clusters in solution and to crystallise homo- and heteronuclear transition-metal complexes and clusters. Furthermore, the use of IL as solvent provides the option to replace high-temperature routes, such as crystallisation from the melt or gas-phase deposition, by convenient room- or low-temperature syntheses. Inorganic IL composed of alkali metal cations and polynuclear transition-metal cluster anions are also known. Each of these areas will be discussed briefly in this contribution. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Ionic liquids as crystallisation media for inorganic materialsAhmed, Ejaz, Breternitz, Joachim, Groh, Matthias Friedrich, Ruck, Michael 09 April 2014 (has links) (PDF)
Ionic liquids (ILs) have made a great impact on materials science and are being explored for potential applications in several disciplines. In this article, we briefly highlight the current state-of-the-art techniques employing ILs as new crystallisation media, working as neutral solvent, template or charge compensating species. The use of an IL as environmental friendly solvent offers many advantages over traditional crystallisation methods. The change from molecular to ionic reaction media leads to new types of materials being accessible. Room temperature ILs have been found to be excellent solvent systems for the crystallisation of a wide range of substances and morphologies ranging from nanoscopic crystals to micro- and even to macroscopic crystals. Moreover, high temperature routes, such as crystallisation from melts or gas phase deposition, have been replaced by convenient room or low temperature syntheses, employing ILs as reaction media. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.
