UNLABELLED The procedure using a tilt-table is far better standardized and less dependent on the patient's compliance compared to the active manoeuvre of standing up. The object of this study is to detect to what extent results are comparable concerning hormonal regulation and the adaptation of blood pressure. In 20 males (59.1 +/- 10.9 years), without any(More)
Orthostatic hypotension is common in Parkinsonian patients. It is probably caused by reduced noradrenaline (NA) release. This effect is further enhanced by therapeutic use of ergot alkaloid dopamine agonists. In this trial we studied the impact of the non-ergot dopamine agonist ropinirole on blood pressure and noradrenaline release in 12 patients suffering(More)
OBJECTIVE To determine whether abnormal orthostatic regulation commonly occurs in patients with Parkinson's disease (PD) and is caused by an abnormal catecholamine release (especially of noradrenaline). PATIENTS AND METHODS Blood pressure and catecholamine concentration were measured after 10-min recumbency and 1, 3, 5, 7 and 9 min after standing up in 46(More)
There are many methods to choose from in the investigation of the autonomic nervous system. The value of the individual tests to the clinician varies according to the method of investigation used. No one test can elucidate all the information needed for all functional disturbances. As a routine, measurement of blood pressure and heart rate reaction to(More)
BACKGROUND Ultrasound measurement of the antral cross-sectional area of the stomach, performed in the supine position, has been described for preoperative assessment of gastric content in the adult, but, to date, no study has determined the cut-off value of the antral area for the diagnosis of an empty stomach in the parturient. Nevertheless, previous(More)
