Prediction of individual outcome after cardiopulmonary resuscitation is of major medical, ethical, and socioeconomic interest but uncertain. We studied the early predictive potency of evoked potential recording after cardiac arrest in 66 resuscitated patients who returned to spontaneous circulation but were unconscious and mechanically ventilated.

Atherosclerotic stenosis of the carotid arteries decreases cerebral flow volume and perfusion, and may result in brain dysfunction. We studied the relationship between the degree of carotid artery stenosis and cognitive brain function in non-demented patients. Cognitive brain function was assessed in 76 patients with carotid artery stenosis (38 patients(More)
Cognitive brain dysfunction is a common complication of end-stage renal disease. To investigate the cerebral effect of renal transplantation, we studied P300 event-related potentials--an objective marker of cognitive brain function--trailmaking test and Mini-mental state in 15 chronic hemodialysis patients and 45 matched healthy subjects. Before(More)
BACKGROUND Zenker's diverticulum is associated with characteristic symptoms of progressive dysphagia and regurgitation. As most patients are elderly, the perioperative risk is usually high. We report our clinical experience with the transoral endoscopic staple-assisted method, including a thorough assessment of the symptomatic relief achieved by the(More)
BACKGROUND The effects of cardiac transplantation on cognitive brain function are uncertain. METHODS AND RESULTS We measured cognitive brain function and quality of life in out-of-hospital cardiac transplant candidates (n = 55; ejection fraction, 19.9%; age, 54.8 years [means]). After transplantation, the patients were serially reevaluated at 4 months (n(More)
OBJECTIVES To determine the predictive ability of sensory evoked potential recordings in nontraumatic comatose patients. To evaluate the hypothesis that patients with bilateral absent cortical responses ultimately die despite long-term intensive care treatment. DESIGN Prospective cohort study. SETTING Medical intensive care unit (ICU) of a university(More)
Sensory evoked potentials are markedly changed in patients with fulminant liver failure. It is unknown, however, whether serial recordings of sensory evoked potentials provide useful prognostic informations for patient management in fulminant liver failure. Ninety recordings of bilateral median nerve-stimulated short- and long-latency sensory evoked(More)
Acute hepatic failure is characterized by jaundice and hepatic encephalopathy within eight weeks after the onset of disease. Although acute hepatic failure is a rare occurrence, its rapid progression and high mortality (50 to 90%, depending on the etiology of disease) necessitate immediate intervention. In the absence of causal therapy, orthotopic liver(More)
Acute liver failure is defined as acute severe, potentially reversible hepatic failure complicated by cerebral dysfunction. The high mortality rate of between 50% and 90% justifies early transfer to a specialised centre with the possibility of orthotopic liver transplantation to ensure adequate intensive care monitoring and treatment, 57 patients with acute(More)
