If symptoms appeared shortly after a medication reached steady state, it is likely that the medication is the cause. Mathias CJ. Midodrine Study Group. Stroke. Orthostatic means an upright posture. Members of various family practice departments develop articles for “Problem-Oriented Diagnosis.” This is one in a series from the Department of Family and Community Medicine at Southern Illinois University School of Medicine, Springfield. If it is not possible to stop the medication, other causes might be considered; it also may be necessary to treat the orthostatic hypotension pharmacologically or by some other method (Table 4).8,12–15, Dorsiflex feet several times before standing Make slow, careful changes in position Eat small, frequent meals Increase salt and fluid intake Elevate head of bed 5 to 20 degrees Schedule activities in the afternoon Wear compression stockings, Rising quickly after prolonged lying or sitting. McElligott MA. Blood West J Med. Hoeldtke RD, Hossain M, The sympathetic nervous system adjusts the tone in arteries, veins, and the heart. Kojima S, Orthostatic hypotension is defined as a fall in systolic blood pressure of at least 20 mmHg or the diastolic blood pressure of at least 10 mmHg between the supine reading and the upright reading. Sutton R. Lipsitz LA. Lipsitz LA. 1993;329:611–5. 1 Orthostatic hypotension is a common condition affecting 18.4% of community-dwelling older adults and 22.2% of adults in long-term care facilities.

Orthostatic hypotension, which is a physical finding, not a disease, may be symptomatic or asymptomatic.1 The American Autonomic Society (AAS) and the American Academy of Neurology (AAN) define orthostatic hypotension as a systolic blood pressure decrease of at least 20 mm Hg or a diastolic blood pressure decrease of at least 10 mm Hg within three minutes of standing up.1 [Evidence level C, consensus/expert guidelines] The AAS and AAN also provide a tilt-table definition.1 This determination has limited usefulness for the approach outlined in this article and appears to have a high rate of false-positive results.2,3, Orthostatic hypotension has been observed in all age groups, but it occurs more frequently in the elderly, especially in persons who are sick and frail.4,5 It is associated with several diagnoses, conditions, and symptoms, including lightheadedness soon after standing, an increased rate of falls, and a history of myocardial infarction or transient ischemic attack6; it also may be predictive of ischemic stroke.7, When an adult rises to the standing position, 300 to 800 mL of blood pools in the lower extremities.8,9 Maintenance of blood pressure during position change is quite complex; many sensitive cardiac, vascular, neurologic, muscular, and neurohumoral responses must occur quickly.9 If any of these responses are abnormal, blood pressure and organ perfusion can be reduced. Comprehensive and authoritative, Hypertension in the Elderly offers family practitioners and general internists an up-to-date, user-friendly reference on the diagnosis, treatment, and complications of hypertension in the elderly. The Director of this study, Abraham Kagan, has comprehensively summarized the design and main finndings of the study in this book. Grubb BP, The Consensus Committee of the American Autonomic Society and the American Academy of Neurology. Ms. Davis earned her nursing degree at Millikin University, Decatur. Treatment of orthostatic hypotension with erythropoietin. Consensus statement on the definition of orthostatic hypotension, pure autonomic failure, and multiple system atrophy. New York: McGraw-Hill, 2001. If a patient has posturally induced symptoms without blood pressure changes, the physician should consider other conditions. 2000;31:2307–13.

LaBaw F, Smith R, It may contribute to disability and even death. Orthostatic hypotension is a sudden drop in blood pressure when you stand from a seated or prone (lying down) position. Etiologies and Drugs That Can Cause Orthostatic Hypotension, Findings on history and physical examination. 10 The fall in BP is enhanced by the duration of the previous supine position. Orthostatic hypotension is defined as a sustained fall in systolic blood pressure of a least 20 mm Hg or a fall in diastolic blood pressure of at least 10 mm Hg within 3 minutes of standing. Introduction. Hollister AS. Increasing salt and fluid intake often is an initial step, although it may be difficult to undertake in some patients, such as those with severe congestive heart failure. Suwa S, Orthostatic hypotension may have more than one cause; a patient with mild neurogenic orthostatic hypotension who becomes dehydrated or starts taking a new medication could develop symptomatic orthostatic hypotension. Arnett DK, 18. Orthostatic hypotension is diagnosed when systolic BP drops by ≥ 20 mm Hg or diastolic BP drops by ≥ 10 mm Hg within 3 minutes of standing. In one volume, this Encylopedia thoroughly covers these ailments and also includes in-depth analysis of less common and rare heart conditions to round out the volume's scope. Freeman R, Willner CL, If the person does not get these symptoms, there is still a strong likelihood that the person has orthostatic hypotension (OH). Each contains clinical data items from the history, physical examination, and laboratory investigations that are generally included in a comprehensive patient evaluation. Annotation copyrighted by Book News, Inc., Portland, OR Increased appetite is a common side effect, along with an increased sense of well-being.14,15. Rose KM, Efficacy of midodrine vs placebo in neurogenic orthostatic hypotension. 2000;84:509–14. Orthostatic hypotension (OH) is a common condition characterized as a drop in blood pressure that occurs when a person stands up. Neurology. If there is inadequate intravascular volume, impairment of the autonomic nervous system, reduction of venous return, or inability of the heart to beat more rapidly or with greater power, orthostatic hypotension may result. 17. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Diabetes and hypertension have evolved as two of the modern day epidemics affecting millions of people around the world. Neurology. To be "classic OH", the systolic blood pressure (top number) has to go down by at least 20 mmHg or the diastolic (bottom number) drops by 10 mmHg or more. In patients with neurogenic orthostatic hypotension, neurogenic supine hypertension is defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, measured after at least 5 min of rest in the supine position. This evidence summary considers midodrine, the first medicine to receive a UK marketing authorisation for orthostatic hypotension (due to autonomic dysfunction). Copyright © 2003 by the American Academy of Family Physicians. Wait two minutes. The patient should continue to stand. Two minutes after the first standing measurement (and after three minutes total of standing), a second standing blood pressure value should be obtained. Inflate the cuff again and record the systolic and diastolic blood pressures. In this review article, we describe the physiology of standing (orthostasis) and the pathophysiology of orthostatic hypotension. This fourth edition of Autonomic Failure (now available in paperback) covers the many recent advances made in our understanding of the autonomic nervous system. There are 20 new chapters and extensive revisions of all other contributions. Ooi WL, 1. The drop in blood pressure (BP) and symptoms can come at different times. N Engl J Med. Mader SL, The cause isn't always known. 15th ed. Low prevalence of postural hypotension among community-dwelling elderly. The autonomic nervous system plays an important role in maintaining blood pressure when a person changes position. In some patients, stopping a medication may cause more harm than benefit if the hypotension symptoms are mild. Gordon C, 6. A patient with symptomatic orthostatic hypotension who has a disease with no complete or specific cure may benefit from nonpharmacologic interventions. Although it is not part of the formal definition of orthostatic hypotension, the absence of a significant increase in heart rate along with a significant postural decrease in blood pressure may suggest an autonomic cause.13. Fealey RD, Clinical disorders of the autonomic nervous system associated with orthostatic intolerance: an overview of classification, clinical evaluation, and management. It can be the initial sign, and lead to incapacitating symptoms in primary and secondary autonomic disorders. a) Dose and administration Initial dose 2.5mg three times a day, increase if necessary at weekly intervals to maximum of 10mg three times a day. Symptoms can also be subtle or absent. For the missing item, see the original print version of this publication.

This second edition examines the relations of a host of behavioral and biomedical risk factors, in addition to subclinical and clinical CVDs, to brain and cognitive function. The authors indicate that they do not have any conflicts of interests. If medication does not appear to be fully or partly responsible for a patient's symptoms, non-neurogenic etiologies should be considered, and intravascular volume should be determined. Kelley-Gagnon M, Neurogenic orthostatic hypotension (nOH) is a condition in which the autonomic system, which controls the automatic functions of the body, loses the ability to properly regulate blood pressure as one moves from sitting or lying down to standing, or when one changes positions quickly. Get comprehensive guidance on all the drugs you could conceivably encounter in treating the geriatric patient.
