Comparison of the analgesic effects of epidural anaesthesia after surgery. Group R: epidural anaesthesia with 0.75% ropivacaine; Group MR: epidural anaesthesia with 0.75% ropivacaine + 2% mepivacaine (Volume 1:1); Group M: epidural anaesthesia with 2% mepivacaine; OR: operating room; VAS score: 0–10 visual analogue scales. There was no significant difference between Group R and Group MR in the VAS scores at rest or with movement; however, the VAS scores at rest in Group M in 1 and 2 h after leaving the OR were higher than those in Group R or Group MR. The VAS scores at the timepoints of 0.5, 1, and 2 h after leaving the OR in Group M were also higher than those in the other two groups when moving. In addition, there was no significant difference in VAS score among the three groups at 0.5 h after leaving the OR at rest and 0,4, 6, 8, and 12 h after leaving the OR, whether at rest or moving
