ObjectiveTo evaluate the effectiveness of a new regimen of pre-emptive analgesia on the development of postoperative pain after inguinal hernia repair.DesignProspective, double-blind, randomised study.SettingUniversity Hospital, Germany.Subjects70 consecutive patients who had primary unilateral inguinal hernia repairs.InterventionsA new regimen of pre-emptive analgesia with bupivacaine that was infiltrated preoperatively, intraoperatively, and postoperatively was tested. The control group were given saline infiltrations at the same times. Pain was measured up to postoperative day 30 using the visual analogue scale (VAS), the verbal rating scale (VRS), and by recording patient-controlled use of ibuprofen suppositories.ResultsPain was significantly less in the pre-emptive analgesia group than in the control group during the first 10 days postoperatively as assessed by VAS and VRS (p < 0.05). Analgesic consumption was also significantly reduced in the pre-emptive analgesia group (p < 0.05). Multivariate analysis showed that bupivacaine infiltration (pre-emptive analgesia) was associated with significantly less postoperative pain (p < 0.0001).ConclusionThis regimen of pre-emptive analgesia is an effective and safe method of reducing postoperative pain and analgesic consumption after inguinal hernia repair.
