Text: No differences were observed between Marsh and Schnider models in required propofol dose (0. 99 0. 26 vs. 0. 93 0. 31 mg kg (-1), P = 0. 322), decrease in mean blood pressure (25 13 vs. 22 14 %, P = 0. 192) or the need for vasopressors (20 vs. 24 %, P = 0. 800), but the use of the Marsh model resulted in a lower predicted effect-site concentration (2. 3 0. 4 vs. 2. 7 0. 6 g ml (-1), P = 0. 006) and shorter time to induction (296 59 vs. 338 87 s, P = 0. 024).
