Text: In comparison with the placebo group, the fentanyl group consumed less propofol (median 0 [0-60] vs 60 [0-160] mg, respectively ; P < 0. 001), required postoperative analgesia less frequently (22 of 38 patients, 57. 9 % vs 35 of 39 patients, 89. 7 %, respectively ; P = 0. 002), and requested the first analgesic after surgery later (median 5. 8 [1. 9-15. 6] vs 3. 1 [1. 0-11. 7] hours, respectively ; P < 0. 001), whereas the onset time of sensory blockade was similar in both groups (median 12 [9-18] vs 15 [9-18] minutes, respectively ; P = 0. 18).
