Management of orthostatic hypotension from autonomic dysfunction in diabetics on peritoneal dialysis.
A utonomic neuropathy occurs in over 50% of chronic dialysis patients (1). Since the autonomic nervous system innervates almost every organ of the body, the clinical features may be diverse and widespread. Most of the nerve fibers in the autonomic nervous system are small myelinated or unmyelinated fibers that are affected early in diabetes mellitus (2). Neurogenic orthostatic hypotension is th...
متن کاملCardiovascular autonomic functions & cerebral autoregulation in patients with orthostatic hypotension
BACKGROUND & OBJECTIVES Patients of orthostatic hypotension may or may not have symptoms of the cerebral hypoperfusion despite fall in the blood pressure. The present study was done to quantify autonomic functions and cerebral autoregulation in patients of orthostatic hypotension with or without symptoms. METHODS The study was conducted in 15 patients of orthostatic hypotension and 15 age, se...
متن کاملAssociation between supine hypertension and orthostatic hypotension in autonomic failure.
Supine hypertension occurs commonly in primary chronic autonomic failure. This study explored whether supine hypertension in this setting is associated with orthostatic hypotension (OH), and if so, what mechanisms might underlie this association. Supine and upright blood pressures, hemodynamic responses to the Valsalva maneuver, baroreflex-cardiovagal gain, and plasma norepinephrine (NE) levels...
متن کاملAmbulatory norepinephrine treatment of severe autonomic orthostatic hypotension.
OBJECTIVES This study was designed to establish a patient-controlled, ambulatory norepinephrine treatment of refractory orthostatic hypotension due to primary autonomic failure. BACKGROUND Autonomic dysfunction leads to disabling postural hypotension. Particularly in primary autonomic dysfunction, repeated syncope and immobilization can be the result. Medical treatment of orthostatic hypotens...
متن کاملOrthostatic hypotension.
A 29-year-old white woman (weight, 1211b; height, 5 ft 6 in.) was referred to the Hypertension Unit of Massachusetts General Hospital in December 1984. She had been athletic and apparently in excellent health until September 1979 when she contracted an upper respiratory tract infection associated with wheezing. She was treated with prednisone for 5 days with resolution of the symptoms but later...
