BACKGROUND AND STUDY AIMS Adequate sedation of the patient is required for diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP). The anesthetic propofol, with its shorter half-life, affording better control, offers an alternative to the benzodiazepine midazolam. The aim of this randomized, controlled, unblinded study was to(More)
The prebolus technique allows one to quantify perfusion in the human heart with a low variability by means of MRI. In this study the prebolus technique was used to determine quantitative perfusion values in the human heart under adenosine stress and to measure the myocardial perfusion reserve (MPR). Twelve healthy volunteers were examined using the(More)
UNLABELLED Midazolam, a benzodiazepine with amnestic and sedative effects is the drug of choice for sedation of patients undergoing upper gastrointestinal endoscopy. Propofol, a phenolic derivate, is a short-acting anesthetic producing a more rapid onset sedation amnesia and a shorter recovery than midazolam: In higher doses it acts as hypnotic. The aim of(More)
PURPOSE MR stress perfusion imaging of the heart allows the quantification of myocardial perfusion and the evaluation of myocardial perfusion reserve (MPR) and the ratio of subendocardial to subepicardial perfusion at rest and under adenosine stress. The aim of this study was to evaluate a high-resolution GRAPPA sequence for quantitative MR first pass(More)
In a prospective study right atrial pressures and parameters of blood coagulation were monitored during anaesthesia and postoperatively in 60 surgical patients. 30 patients received spinal anaesthesia. 30 patients were intubated for general anaesthesia. One third of the patients in each group were injected with heparindihydroergotamine s.c., another third(More)
