Objective : To compare the postoperative pain following inguinal herniorrhaphy. Methods : Ninety, ASA I-III, aged 17-70 year patients with elective, unilateral, non-recurrent, indirect inguinal hernia undergoing Bassini repair were randomly allocated into3 groups. Group I received spinal anesthesia with 0.5% hyperbaric bupivacaine, group II received general anesthesia together with (SB) 0.25% bupivacaine inguinal field block (GA c BIFB) 20 ml before surgery and group III received general anesthesia with 0.25% bupivacaine instillation (GA c BI) 10 ml after herniorrhaphy before closure of the external fascia. General anesthesia via laryngeal mask airway (LMA) was performed with propofol 1.5-2.5 mg/kg and maintained with N2O / O2 / Sevoflurane. Outcome measurement : Postoperative pain scores (VAS 0-10 cm) were assessed at 0, 1/2, 1, 1 1/2 , 2, 3, 4 , 6, 8, 12 and 24 hours after surgery.Results: Within 24 hours after surgery, average postoperative pain scores (mean VAS) in group I (SB) was 1.91 cm, group II (GA c BIFB) was 1.40cm and group III (GA c BI) was 1.83 cm and postoperative morphine requirement per patient in group I (SB) was 3.77 mg, group II (GA c BI) was 4.40 mg. There was no significant difference between patients who received the three treatment modalities. Conclusion : The three anesthetic techniques for 24 hours postoperative pain control following inguinal herniorrhaphy in adult were no significant difference.
