In 37 patients with intracranial tumros, regional cerebral blood flow was measured. The typical abnormalities are described and an attempt is made to correlate the blood flow with the histologic type of tumor. Moreover, the deranged cerebral vasomotor responses are demonstrated when the flow is measured during functional tests. The practical value of the(More)
These studies were conducted to determine the effect of anesthetic drugs on tissue perfusion and O2 supply in the brain with focal cerebral edema. Using an open cranium preparation, we studied the effects of isoflurane (I; 1 minimum alveolar anesthetic concentration), of fentanyl (F; 0.5-1 microgram.kg-1 x min-1), or of thiopental (T; 32.5 mg.kg-1 x h-1) on(More)
The effects of total parenteral nutrition (TPN) versus enteral nutrition (TEN) were studied in 34 patients following major neurosurgery. Measurements were made of resting energy expenditure (REE), urea production rate (UPR), visceral proteins, parameters of liver and pancreas function, as well as gastrointestinal absorption. To predict nutritional status,(More)
Extracranial intracranial arterial anastomosis is gaining acceptance as a form of treatment in selected cases with ischemic cerebrovascular disease. To establish indications for this operation and to provide an objective assessment of postoperative results, regional cerebral blood flow (rCBF) studies were performed in 110 patients with cerebrovascular(More)
Anaesthetic agents reduce cerebral metabolism and may impair coupling of cerebral blood flow and metabolism. We analyzed the effects of isoflurane (I) (1 MAC), fentanyl (F), thiopental (T) (32.5 mg/kg x hr) and alpha-chloralose (C) on rCBF and brain oedema formation after a focal cerebral injury (cold lesion) in rabbits (n = 6 per group). In the isoflurane(More)
