Fig. 1From: Effects of isoflurane, sevoflurane, propofol and alfaxalone on brain metabolism in dogs assessed by proton magnetic resonance spectroscopy (1H MRS)Schematic timeline for propofol and alfaxalone (a) and isoflurane and sevoflurane (b) The 30Â min equilibration phase was followed by a measurement period of approximately 30Â min where a total of three measurements were performed (BG, PL and OL). For treatment I and S the end expiratory concentration had to be adjusted before each equilibration phase. Jugular venous blood samples were taken for serum glucose, lactate and plasma concentrations of propofol and alfaxaloneBack to article page
