Figure 1

Visual analog scale (VAS) score comparison at baseline, 15, 30, and 60 minutes in both groups on the postanesthesia care unit. There were significant VAS score declines in both groups (P < 0.05). Ropivacaine plus fentanyl (R + F) group showed slightly lower VAS scores than R group at 15, 30, and 60 minutes. R + F group showed significant lower VAS score compared to control group at 30 minutes. However, there were no significant differences of VAS scores between groups at the other time points. ∗P < 0.05 compared with R group.
