Cerebral blood flow and metabolism during infusion of norepinephrine and propofol in patients with bacterial meningitis.
BACKGROUND AND PURPOSE In patients with severe bacterial meningitis, norepinephrine is often infused to increase mean arterial pressure (MAP). This increases cerebral blood flow (CBF), but it is unknown if this increase is caused by impaired cerebral autoregulation or by a cerebral effect of norepinephrine through increased cerebral metabolism. The latter possibility implies a CBF-metabolism co...
متن کاملFat Metabolism during Exercise
2. As exercise progresses from low to moderate intensity, e.g., 25-65% VO2max, the rate of fatty acid mobilization from adipose tissue into blood plasma declines, whereas the rate of total fat oxidation increases due to a relatively large use of intramuscular triglycerides. Intramuscular triglycerides also account for the characteristic increase in fat oxidation as a result of habitual enduranc...
متن کاملPropofol infusion syndrome.
The clinical features of propofol infusion syndrome (PRIS) are acute refractory bradycardia leading to asystole, in the presence of one or more of the following: metabolic acidosis (base deficit > 10 mmol.l(-1)), rhabdomyolysis, hyperlipidaemia, and enlarged or fatty liver. There is an association between PRIS and propofol infusions at doses higher than 4 mg.kg(-1).h(-1) for greater than 48 h d...
متن کاملPharmacokinetics of an infusion of propofol during cardiac surgery.
We have measured whole blood concentrations and pharmacokinetics of propofol administered as a constant rate infusion during cardiac surgery. Ten patients undergoing elective cardiac surgery involving cardiopulmonary bypass (seven myocardial revascularization and three aortic valve surgery) received a continuous infusion of propofol 4 mg kg-1 h-1 to supplement alfentanil analgesia. Whole blood ...
متن کاملContinuous infusion of propofol in dystrophia myotonica.
The use of intravenous infusions of propofol and atracurium in a 41-year-old woman, weighing 64 kg, with dystrophia myotonica during major oral surgery is described. Propofol and atracurium, in total doses of 2488 mg and 75 mg respectively, were used during the four-hour procedure. There were no intraoperative problems and operating conditions were excellent. Emergence was rapid and there were ...
