Fig. 4From: Effect-site concentration of propofol required for LMA-Supreme™ insertion with and without remifentanil: a randomized controlled trialDose–response curves plotted from logistic analysis of individual propofol concentrations illustrating reactions to LMA-Supreme™ insertion. EC50 in propofol + saline group: 6.09 μg.mL−1; EC50 in propofol + remifentanil group: 2.11 μg.mL−1; EC95 in propofol + saline group: 12.09 μg.mL−1; EC95 in propofol + remifentanil group: 4.33 μg.mL−1Back to article page
