Introduction The presence of postural hypotension complicating amyloid disease has been well documented. Kyle, Kottke & Schirger (1966) reviewed the case records of 138 patients in the Mayo Clinic in whom the diagnosis had been confirmed by biopsy or necropsy. In eleven (9%) of these cases postural hypotension was found. The following signs and symptoms were attributed to an amyloid autonomic n...

BACKGROUND We aim to report the incidence of post-intubation hypotension in the critically ill, to report in-hospital mortality and length of stay in those who developed post-intubation hypotension, and to explore possible risk factors associated with post-intubation hypotension. MATERIAL/METHODS Adult (≥18 years) ICU patients who received emergent endotracheal intubation were included. We ex...

Previous experiments have indicated that arterial hypotension increases plasma oxytocin (OT) levels in rats and that OT infused intravenously causes an increase in plasma renin activity (PRA). The goal of the present study was to determine whether systemic administration of an OT receptor antagonist would attenuate the increase in PRA that is normally evoked by arterial hypotension in rats. In ...

BACKGROUND Spinal anesthesia is a standard technique for cesarean section but can cause hypotension which may be related to venous pooling secondary to progesterone-induced decreases in vascular tone. This study investigated the use of a sequential compression mechanical pump with thigh-high sleeves with compression cycles timed to venous refilling. We hypothesized that this would recruit poole...

OBJECTIVE Hypotension is associated with increased mortality, however previous studies have failed to account for the depth and duration of hypotension. We evaluated the effect of the duration of hypotension on outcome in injured patients. METHODS Trauma patients admitted to the intensive care unit (ICU) from 1999 to 2000 were prospectively evaluated. Patients transferred to a ward </= 48 hou...

INTRODUCTION Orthostasis is a frequent trigger for (pre)syncope but some forms of orthostatic (pre)syncope have a worse prognosis than others. Routine assessment of orthostatic BP in the ED can detect classic orthostatic hypotension, but often misses these other forms of orthostatic (pre)syncope. This study aimed to determine the frequency of abnormal orthostatic BP recovery patterns in patient...

Neurogenic orthostatic hypotension and supine hypertension are common manifestations of cardiovascular dysautonomia in Parkinson's disease and related synucleinopathies. Because these disorders are haemodynamic opposites, improvement in one might be achieved at the expense of worsening of the other. Thus, management decisions necessitate assessment of the individual risks for patients with coex...

background:organophosphates are commercially available agrochemicals for pest control, but may be abused for deliberate self-poisoning. we report a case of suicidal ingestion of dimethoate, a moderately toxic organophosphate insecticide, which can cause refractory hemodynamic instability, and the successful use of methylene blue (mb) for counteracting this complication. case presentation: an un...

objective midazolam is a significant and effective drug for control of a life-threatening condition, generalized and partial refractory convulsive status epilepticus. the goal of this study was evaluation of midazolam efficacy for management of this serious disease and its two side effects, hypotension and respiratory failure. materials & methods our study was done using a quasi experimental me...
