PURPOSE We developed a monitoring system to detect spinal cord ischemia during aortic cross-clamping (AXC). This system was used to prospectively determine in which patients ischemia occurs, in which patients reimplantation of intercostal arteries is unnecessary or mandatory, and when reperfusion of intercostal arteries (ICAs) is urgent. METHODS Two(More)
To determine the effects of vasomotor tone on intrathoracic and splanchnic blood volume, the distribution of radioactively (99mTc) labeled erythrocytes was recorded by whole body scintigraphy before and during peridural anesthesia (PDA) in eight supine men. The radioactivity was recorded with a gamma camera and its distribution determined in the thorax,(More)
Die Verwendung von Doppellumentuben zur Einlungenbeatmung bei Eingriffen an der thorakalen Aorta hat die Inzidenz von Lungentraumen gesenkt und die Operationsbedingungen verbessert. Intubationsschwierigkeiten des linken Hauptbronchus, insbesondere bei großen Aortenaneurysmen, und Beatmungsprobleme infolge Dislokation während der Operation sind bekannte(More)
Today, the requirements infusion pumps and syringe pumps have to meet concerning the maximum pressure limit are based on aspects of technical feasibility rather than on clinical needs. Since, in the case of common operational disorders, factors such as time to alarm, bolus volume and accuracy depend on the pressure characteristics, a maximum pressure limit(More)
Between 1977 and 1986, 185 patients with deep venous thrombosis (117 with acute occlusive and 68 with embolizing deep venous thrombosis) underwent venous thrombectomy with arterio-venous fistula. The early patency rate was 96%, and the perioperative mortality rate, 3.8%. Of the 157 patients in whom extremities were involved, 147 were examined 12–118 months(More)
Ninety-nine patients underwent surgery for thoraco-abdominal (n = 73) or suprarenal (n = 26) aortic aneurysm, between January 1, 1981 and May 10, 1988. The in-graft technique was combined with re-implantation of renal, visceral, and segmental arteries, using the method proposed by Crawford. Ischaemic tolerance of kidneys was extended by means of flush(More)

Dihydroergotamine (DHE) preferentially constricts capacitance vessels in the skin and striated musculature, thereby redistributing blood in favor of the pulmonary vascular bed in the presence of neurogenic vascular tone. The aim of this study was to see if DHE would act likewise when neurogenic vascular tone is absent. Filling and blood flow of the calves(More)
A maximum pump output pressure under 15 psi which is adapted to the necessary back pressures and flow pressures can provide a reduction of problems related to pressure build-up. Thus, the time to alarm in case of occlusion and the bolus dosage after removal of the obstruction can be minimized. This is important in the use of critical drugs with short(More)
