Postprandial Hypotension

The American Journal of Medicine, 2010
Postprandial hypotension is both common in geriatric patients and an important but under-recognized cause of syncope. Other populations at risk include those with Parkinson disease and autonomic failure. The mechanism is not clearly understood, but appears to be secondary to a blunted sympathetic response to a meal.

Association between Intraoperative Hypotension and Myocardial Injury after Vascular Surgery

Anesthesiology, 2016
Background:Postoperative myocardial injury occurs frequently after noncardiac surgery and is strongly associated with mortality. Intraoperative hypotension (IOH) is hypothesized to be a possible cause.

Permissive hypotension versus conventional resuscitation strategies in adult trauma patients with hemorrhagic shock: A systematic review and meta-analysis of randomized controlled trials

Journal of Trauma and Acute Care Surgery, 2018
BACKGROUND Aggressive fluid resuscitation in trauma promotes deleterious effects such as clot disruption, dilutional coagulopathy and hypothermia. Animal studies suggest that permissive hypotension maintains appropriate organ perfusion, reduces bleeding ...

Spontaneous Intracranial Hypotension Without Intracranial Hypotension

Journal of Neuro-Ophthalmology, 2011
A 52-year-old man with a family history of multiple aneurysms presented with the gradual onset of generalized headaches and bilateral sixth nerve palsies. Following intravenous contrast, MRI revealed diffuse pachymeningeal enhancement consistent with spontaneous intracranial hypotension (SIH).

Management of supine hypertension in patients with neurogenic orthostatic hypotension: scientific statement of the American Autonomic Society, European Federation of Autonomic Societies, and the European Society of Hypertension.

Journal of Hypertension, 2019
: Supine hypertension commonly occurs in patients with neurogenic orthostatic hypotension due to autonomic failure. Supine hypertension promotes nocturnal sodium excretion and orthostatic hypotension, thus, interfering with quality of life.

THE HYPOTENSIVE STROKE

The Lancet, 1980
In a retrospective study of necropsies done in a general hospital over five years (1971-75), fatal strokes in elderly patients often appeared to be due to acute hypotension caused by such extracranial events as heart-failure, occult haemorrhage, or multiple pulmonary emboli.

Association between Intraoperative Hypotension and Hypertension and 30-day Postoperative Mortality in Noncardiac Surgery

Anesthesiology, 2015
Background:Although deviations in intraoperative blood pressure are assumed to be associated with postoperative mortality, critical blood pressure thresholds remain undefined.

Orthostatic hypotension

Clinics in Geriatric Medicine, 2002
A common problem among elderly people, orthostatic hypotension is associated with significant morbidity and mortality, which may be caused by medications, the cumulative effects of age- and hypertension-related alterations in blood pressure regulation, or age-associated diseases that impair autonomic function.

Norepinephrine Intermittent Intravenous Boluses to Prevent Hypotension During Spinal Anesthesia for Cesarean Delivery: A Sequential Allocation Dose-Finding Study

Anesthesia and Analgesia, 2017
BACKGROUND: The use of phenylephrine as the first-line agent for prevention and treatment of maternal hypotension during cesarean delivery (CD) may reduce cardiac output, posing a theoretical risk to mother and fetus. Norepinephrine has been suggested as

Spontaneous Intracranial Hypotension

CONTINUUM: Lifelong Learning in Neurology, 2001
Spontaneous intracranial hypotension results from CSF volume depletion, nearly always from spontaneous CSF leaks. Spontaneous intracranial hypotension is increasingly diagnosed in practice; the number of atypical, unconfirmed, and doubtful cases is also increasing, as are treatment failures. These confront neurologists and create many challenges.
