Sympathetic nervous system activity in patients with subarachnoid hemorrhage.
In patients with subarachnoid hemorrhage there were increased concentrations of plasma epinephrine and norepinephrine when compared with those concentrations in a group of patients admitted to hospital with other illness. Reassessment after a variable period showed that in patients whose eventual clinical result was poor the plasma epinephrine and norepinephrine concentrations increased further...
متن کاملIncreased sympathetic nervous activity in patients with nontraumatic subarachnoid hemorrhage.
BACKGROUND AND PURPOSE Activation of the sympathetic nervous system, which leads to elevation of circulating catecholamines, is implicated in the genesis of cerebral vasospasm and cardiac aberrations after subarachnoid hemorrhage. To this juncture, sympathetic nervous testing has relied on indirect methods only. METHODS We used an isotope dilution technique to estimate the magnitude and time ...
متن کاملSympathetic nervous activity and myocardial damage immediately after subarachnoid hemorrhage in a unique animal model.
BACKGROUND AND PURPOSE Obvious cardiac dysfunction, including ECG abnormalities and left ventricular asynergy, is known to develop after subarachnoid hemorrhage (SAH). To clarify the close relationship between myocardial damage and sympathetic nervous activity immediately after SAH, a novel experimental animal model was used. METHODS SAH was provoked by perforation of the basilar artery with ...
متن کاملNimodipine increases fibrinolytic activity in patients with aneurysmal subarachnoid hemorrhage.
BACKGROUND AND PURPOSE The purpose of this study was first, to investigate which factor in the fibrinolytic cascade is responsible for the recently observed increase of fibrinolytic activity in patients with aneurysmal subarachnoid hemorrhage (SAH), and second, the cause of this increase. METHODS Fibrinolytic activity and the main regulators of endogenous fibrinolytic activity, tissue plasmin...
متن کاملComparative Efficacy of Meloxicam and Placebo in Vasospasm of Patients with Subarachnoid Hemorrhage
Cerebral vasospasm considered to be a serious cause of morbidity and mortality following subarachnoid haemorrhage (SAH).Despite several available therapeutic options, current protocols do not prevent major consequences of vasospasm. Inflammation is believed to play an important role in post-haemorrhagic vasospasm. Meloxicam is a non-steroidal anti-inflammatory drug. The aim of this study was to...
