This trial was designed to study the correlation between peri-operative mortality in patients undergoing elective surgery and the physical status classification of the American Society of Anesthesiologists, the Goldman multifactorial cardiac risk index or the two indices combined. All patients scheduled for elective surgery over a 5-year period were(More)
During cardiopulmonary resuscitation, pH and base excess (BE) decrease to a variable degree due to metabolic acidosis. The main cause has been shown to be lactate, which cannot be eliminated sufficiently because of low perfusion during cardiac massage. Both BE and lactate can be measured in the prehospital phase. The aim of the study was to determine if BE(More)
Background: This study evaluated the feasibility of blood gas analysis and electrolyte measurements during emergency transport prior to hospital admission. Results: A portable, battery-powered blood analyzer was used on patients in life threatening conditions to determine pH, pCO2, pO2, sodium, potassium and ionized calcium. Arterial blood was used for(More)
OBJECTIVE Appropriate emergency measures are essential in improving the outcome of patients with thoracic injuries. Pathophysiological background and basic principles of emergency treatment decisions should be already taught in undergraduate medical curricula. The effectiveness of a computer simulation model on thoracic trauma management was evaluated. (More)
Im klinischen Bereich ist beim kritisch kranken Patienten die Blutgasanalyse unverzichtbar. Auch in der Notfallmedizin bestehen möglicherweise absolute Indikationen für eine präklinische Blutgasanalyse (=BGA). Mit Hilfe der BGA kann eine Azidosepufferung bei der kardiopulmonalen Reanimation (CPR) bzw. beim kardiogenen Schock gezielt durchgeführt werden.(More)
Various clinical parameters, neurological examination models, biochemical tests, electrophysiological procedures and neuro-imaging techniques have been studied with respect to the detection of cerebral hypoxia in patients after cardiopulmonary resuscitation. These parameters were critically evaluated by the members of the Austrian interdisciplinary(More)
Diese Untersuchung beschreibt die Anwendungssicherheit und die Unterschiede von drei tragbaren Geräten zur Bestimmung der Blutgaswerte im präklinischen Einsatz. Alle getesteten Geräte sind im Notarztdienst anwendbar. Der OPTI 1 entspricht am ehesten der Genauigkeit und Funktionssicherheit eines stationären Geräts. Dies schlägt sich jedoch in deutlich(More)
A high-risk patient is a challenge to the anaesthesiologist. If surgical intervention is indicated the perioperative anaesthesiological management has to be carefully adapted to the requirements of the patient. If the patient is classified a high-risk at the preoperative anaesthesiological assessment, the therapeutic management has to aim at optimizing the(More)
Ein neues, tragbares Gerät zur Blutgasanalyse (BGA) wurde über 6 Monate im Grazer Notarztsystem getestet. Durch ein neuentwickeltes Einmalkassettensystem erübrigt sich das Kalibrieren und Mitführen von Reagenzien. Als Indikationen für die präklinische BGA galten die kardiopulmonale Reanimation (CPR), die kontrollierte Beatmung, die Hyperventilation bei(More)
PURPOSE To report the anaesthetic management of a case of tracheal rupture, using different types of ventilation and additional hyperbaric oxygenation (HBO). CLINICAL FEATURES An 8 cm postintubation tracheal tear was repaired in a 66-yr-old woman with acute myocardial reinfarction, mediastinal and subcutaneous emphysema, cardiac failure and unrecognized(More)
