Preblock group, nerve blockade was performed before emergence from general anesthesia; no preblock group, nerve blockade was not performed before emergence from general anesthesia. VAS, visual analog scale; VASAUC, VAS score area under the curve; VASAUC_6, VASAUC for postoperative hour 6; VASAUC_12, VASAUC for postoperative hour 12; VASAUC_18, VASAUC for postoperative hour 18; VASAUC_24, VASAUC for postoperative hour 24; denotes the operative pain intensity at return to the ward. denotes the operative pain intensity 1 hour after the patient returned to the ward. The number of days with pain denotes the number of days required for postoperative pain to reach 0/100 on the VAS. N, number of patients. Preblock group, N = 22; no preblock group, N = 34. Data are presented as median (interquartile range) values. The t-test was performed to determine the difference between two groups in spite of the analgesic requirement period and number of days with pain, which was performed with the Welch t-test. < 0.05; < 0.005. |
