Orthostatic Hypotension Treatment on Rehab Unit

Orthostatic HypotensionFalls

For patients recovering from acute illness, the ability to stand, walk, climb stairs, and participate in therapy are critical to their recovery and eventual discharge to the least restrictive environment. Orthostatic hypotension is a common finding in medically ill adult and elderly patients and is a potentially reversible contributor to functional impairment. This 4-year project will be a randomized controlled trial of a multidisciplinary-multicomponent intervention to determine whether routine identification and treatment of OH improves functional outcomes such as: balance, fall rates, therapy participation, length of stay, transfer to acute care hospital, and discharge location. Routine screening and management of OH may improve outcomes for rehabilitation and long term care patients, as well other high-risk patient populations.

A Dose Response Trial Using 5 and 10 Mg of Midodrine Hydrochloride

Orthostatic HypotensionSpinal Cord Injury

With upright postures, there is an immediate redistribution of blood to the dependent circulation; venous return and central venous filling pressure are reduced, resulting in diminution of cardiac output and blood pressure. These hemodynamic alterations stimulate the baroreceptor reflex, which is mediated via the central nervous system to increase peripheral sympathetic vasomotor tone, restoring blood pressure and cardiac output within seconds-to-minutes of the assumption of the upright position. Following SCI, individuals often experience the inability to adjust to postural changes due to disruption of central command of the baroreceptor reflex and reduction in efferent sympathetic neural pathways; consequently, orthostatic hypotension (OH) and symptoms of cerebral hypo-perfusion may ensue. OH is a well-documented phenomenon, which is characterized by a fall in systolic blood pressure of >20 mmHg or diastolic BP of > 10 mmHg within 3 minutes of assumption of an upright posture. As a consequence of OH, many individuals experience symptoms of cerebral hypo-perfusion which include lightheadedness, dizziness, blurry vision, fatigue, nausea, ringing in the ears, cognitive impairment and heart palpitations. Although several investigators have reported increased prevalence of OH during the acute phase of spinal cord injury (SCI), individuals with chronic injury also experience significant falls in blood pressure with seated upright postures. This investigation will examine the effects of an alpha-agonist, midodrine hydrochloride, during head-up tilt on systemic blood pressure, cerebral blood flow and cerebral oxygenation compared to placebo administration in persons with chronic SCI who demonstrate significant orthostatic hypotension during a 24-hour observation study. This is the first study to determine the dose response and efficacy of midodrine to improve orthostatic blood pressure and cerebral blood flow and oxygenation in the SCI population.

A Two Part Study (306A/306B) to Assess Droxidopa in Treatment of NOH in Patients With Parkinson's...

Orthostatic HypotensionParkinson's Disease

This is a study to evaluate the effects of an investigational drug, Droxidopa, in participants with neurogenic orthostatic hypotension (NOH), associated with Parkinson's disease. Droxidopa is being studied to determine the effects on blood pressure changes upon standing up (orthostatic challenge). Symptoms and activity measurements, including patient reported falls, will be evaluated to determine the effectiveness of the study drug. Symptoms of NOH may include any of the following: Dizziness, light-headedness, feeling faint or feeling like you may blackout Problems with vision (blurring, seeing spots, tunnel vision, etc.) Weakness Fatigue Trouble concentrating Head & neck discomfort (the coat hanger syndrome) Difficulty standing for a short time or a long time Trouble walking for a short time or a long time The study duration is a maximum of approximately 14 weeks including up to 2 weeks for screening, up to 2 weeks for proper dose finding, followed by an 8 week treatment period and a follow-up visit after 2 weeks. A sufficient number of patients will be screened to allow approximately 211 randomized patients. An extension study is also available to continue treatment if determined appropriate by the study doctor. This Study is NCT01132326 sponsored by Chelsea Therapeutics and is enrolling by invitation only.

Efficacy of Therapeutic Interventions for Orthostatic Hypotension in Parkinson's Disease and Multiple...

Parkinson's DiseaseMultiple System Atrophy1 more

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.

Orthostatic Hypotension in Rehabilitation Patients

HypotensionOrthostatic

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.
