The 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)
