Fig. 2From: Effect of caudal ketamine on minimum local anesthetic concentration of ropivacaine in children: a prospective randomized trialThe response curve of consecutive children in each of the five groups. Skin incisions were attempted at different concentrations of caudal ropivacaine. The MLAC values of ropivacaine were 0.128% (0.03%) in the control group, 0.112% (0.02%) in Group K0.25, 0.112% (0.02%) in Group K0.5, 0.110% (0.02%) in Group K0.75, and 0.110% (0.02%) in Group K1.0. There were no significant differences among the five groups for the MLAC values (p = 0.11)Back to article page
