A significant controversy exists regarding the clinical impact of hemodynamic depression on major adverse events after carotid artery stenting (CAS). The purpose of this study was to evaluate the incidence, predictors, and clinical significance of hypotension after CAS. A total of 118 cases of carotid artery stenosis were treated with CAS. Hypotension was defined as sustained systolic blood pre...

Although adrenaline (epinephrine) is a cornerstone of initial anaphylaxis treatment, it is not often used. We sought to assess whether use of adrenaline in hemodynamically stable patients with anaphylaxis could prevent the development of hypotension. We conducted a retrospective cohort study of 761 adult patients with anaphylaxis presenting to the emergency department (ED) of a tertiary care ho...

Background: Hypotension or bradycardia after spinal anesthesia for cesarean section remain common and are serious complications. The current study evaluated factors associated to the incidences of hypotension or bradycardia in this context. Material and Method: A prospective cross sectional study from November 1, 2004 to July 31, 2005 was conducted on 722 parturients undergoing cesarean section...

The use of spinal anesthesia for cesarean delivery has increased with the introduction of small-gauge, noncutting spinal needles. Most women in Canada, the United States, Australia, and Europe requiring elective cesarean delivery receive some variation of a spinal anesthetic technique owing to the perceived advantages of a clear end point in locating the subarachnoid space, fast onset of local ...

one patient who had milder postural hypotension. Hemodynamic studies were carried out with subjects supine and tilted 450 before and after exercise, following plasma volume expansion, and during the effects of isoproterenol and atropine. Despite disordered venoconstrictor responses demonstrated during exercise, hyperventilation, and after the Valsalva maneuver, decrease in central blood volume ...

BACKGROUND Each year, ~89,000 (180/100,000) new cases of head injury are reported in South Africa (SA), with the majority of patients being in the economically active population. Hypotension and hypoxaemia significantly increase the morbidity and mortality in patients who have suffered a traumatic brain injury (TBI). Cerebral tissue is particularly vulnerable to these secondary insults in the p...

BACKGROUND AND OBJECTIVES Severe and refractory hypotension is an infrequent perioperative situation during non-cardiac surgery, but determining its etiology is essential for successful management and therapy. METHODS Adults undergoing non-cardiac surgery were prospectively enrolled in this study. Severe hypotension was defined as a drop from 30% of baseline systolic arterial pressure unrespo...

AIM To investigate the effect of gradient decompression on the occurrence of intraoperative hypotension and prognosis in traumatic brain injury. MATERIAL AND METHODS A retrospective analysis was performed in 186 hospitalized patients from January, 2008 to January, 2012 in the Affiliated Hospital of Jiangsu University. Demographic data, the abnormality of pupils, and Glasgow Coma Scale (GCS) b...

Methods We reviewed the records of 138 patients with primary systemic amyloidosis seen at the Mayo Clinic from 1935 through 1964. In all instances, the presence of amyloidosis was proved by tissue biopsy or postmortem examination. The criteria for the diagnosis of orthostatic hypotension included a decrease in the standing blood pressure from the recumbent blood pressure of 30 mm Hg systolic an...

OBJECTIVES orthostatic hypotension is a common and potentially dangerous condition in elderly patients, often accompanied by dizziness and falls. To diagnose orthostatic hypotension, many physicians rely on blood pressure measurements performed by nurses. DESIGN observational and descriptive study. SETTING departments of Internal Medicine, Geriatric Medicine, and Surgery in eight hospitals ...
