Filter by:The autonomic nervous system serves multiple regulatory functions in the body, including the regulation of blood pressure and heart rate, gut motility, sweating and sexual function. There are several diseases characterized by abnormal function of the autonomic nervous system. Medications can also alter autonomic function. Impairment of the autonomic nervous system by diseases or drugs may lead to several symptoms, including blood pressure problems (e.g., high blood pressure lying down and low blood pressure on standing), sweating abnormalities, constipation or diarrhea and sexual dysfunction. Because treatment options for these patients are limited. We propose to study patients autonomic failure and low blood pressure upon standing and determine the cause of their disease by history and examination and their response to autonomic testing which have already been standardized in our laboratory. Based on their possible cause, we will tests different medications that may alleviate their symptoms.
This is a study using cerebral oximetry to evaluate the safety of traditionally adopted hypotensive anesthesia.
The purpose of this study is to determine whether continued administration of Drotrecogin Alfa (Activated) up to additional 72 hours - after the so far recommended 96 hour infusion period - results in a more rapid resolution of hypotension in severe septic patients.
This is a study designed to test the hypothesis that treatment with L-carnitine will improve the quality of life and some specific symptoms and signs in patients with renal failure submitted to hemodialysis.
This study will see if a special piece of equipment can help burn patients who have been in bed for a long time to get out of bed without feeling dizzy or faint.
Sodium nitroprusside (SNP) has been approved for control of blood pressure in adults, yet there are no controlled studies in children. The purpose of this study is to determine the efficacy and safety of sodium nitroprusside in children who will be having surgery, and who require blood pressure lowering in order to decrease the amount of blood loss during their surgery.
The purpose of this study is to determine the prevalence and clinical course of orthostatic hypotension (OH) on a rehabilitation and nursing home unit during their inpatient stay and to initiate a standardized, interdisciplinary treatment plan for patients with OH and determine the effect of treatment on the clinical course of OH during their inpatient stay.
The purpose of this study is to determine whether continuing or discontinuing furosemide (a diuretic) on the day of elective noncardiac surgery for those who take furosemide on a chronic basis, causes more intraoperative hypotension (low blood pressure) during surgery. Our hypothesis is that the usual practice of continuing furosemide on the day of surgery would contribute to more hypotension during surgery than discontinuing furosemide.
Patients with Parkinson's Disease or Multiple System Atrophy (MSA), and symptoms of orthostatic hypotension, are eligible for the study. Each patient will have three weeks of conservative therapy, three weeks of therapy with fludrocortisone, and three weeks of therapy with domperidone. Autonomic testing, a symptom questionnaire, bedside blood pressure testing, and Unified Parkinson Disease Rating Scale (UPDRS) will be performed after each intervention.
We are seeking male and female patients to voluntarily take part in a clinical research study. Patients must be aged 18 or older and diagnosed with symptomatic orthostatic hypotension (low blood pressure while in the upright position) due to Parkinson's disease, multiple system atrophy, pure autonomic failure or autonomic neuropathies (i.e. neurogenic orthostatic hypotension). Symptoms of low blood pressure include dizziness, lightheadedness, changes in vision and generalized weakness upon standing. The main effect of the drug being studied is to increase blood pressure in the upright position so symptoms will decrease. The purpose of this clinical study is to further assess the clinical benefit of midodrine hydrochloride (ProAmatine®), an approved treatment for orthostatic hypotension. During the course of the study, participants will receive either ProAmatine® or a placebo. Assessments will be made using questionnaires that measure symptom and activity levels. Blood pressure in the lying down and standing positions will be measured at each visit.
