Subarachnoid Hemorrhage Without Detectable Aneurysm
Background: In 15% to 20%o of patients with a spontaneous subarachnoid hemorrhage, no aneurysm is found on the first angiogram. This review emphasizes that this group of patients is in fact heterogeneous and describes the clinical features, pattern of hemorrhage on early computed tomographic (CT) scan, prognosis, and proposed management in the several and distinct subsets of these patients. Sum...
متن کاملMETABOLIC ACIDOSIS AND SEVERE HYPOTENSION: INFLUENCE ON SURVIVAL TIME AND SHOCK PERIOD DURING HEMORRHAGE IN THE CAT
Metabolic acidosis and severe hypotension are the main causes of irreversibility during hemorrhagic shock. The influence of these two factors on durations of shock period and survival time were studied in four groups of anesthetized cats. In group I the animals were made hypotensive by reducing mean arterial blood pressure (Pa) to 45 mmHg with concurrent metabolic acidosis. [n group II the ...
متن کاملSpontaneous resolution of arteriovenous malformation without hemorrhage.

The patient was told that it was inoperable because of its location, and anticonvulsants were prescribed. In May 1984, poor seizure control ...
متن کاملEffect of hemorrhage and hypotension on transcranial motor-evoked potentials in swine.
BACKGROUND Transcranial motor-evoked potentials (TcMEPs) monitor spinal cord motor tract integrity. Using a swine model, the authors studied the effects of vasodilatory hypotension, hemorrhage, and various resuscitation efforts on TcMEP responses. METHODS Twelve pigs were anesthetized with constant infusions of propofol, ketamine, and fentanyl. Animals were incrementally hemorrhaged, until bi...
متن کاملEffects of Hypotension Due to Hemorrhage and of Blood Transfusion on Renal Function in Dogs
1. Renal blood flow is decreased by hypotension due to bleeding, and glomerular filtration rate is disproportionately decreased. After a first 40 minute stage of hypotension at about 60 mm. Hg infusion of blood with consequent restoration of the general blood volume and arterial pressure usually results in a return to normal of renal blood flow and function although renal blood flow subsequentl...
