Background : We attempted to determine the efficacy of a one plane ilioinguinal and iliohypogastric nerve block with a single shot and double shot techniques. Methods : In a randomized single blind study, 90 children, aged 2–12 years, received a single shot (SS) or a double shot (DS) technique for ilioinguinal and iliohypogastric (IG–IH) nerve block for inguinal hernia repair. In the SS group, 0.25 ml·kg –1 of 0.25% bupivacaine was given one fingerbreadth medial to the anterior superior iliac spine under the external oblique aponeurosis. In the DS group, one‐third of the total dose of bupivacaine was given as for the SS group. The remaining two‐thirds was deposited 0.5 cm above and lateral to the mid‐inguinal point deep to the external oblique aponeurosis. Results : The success rates of both techniques were similar, at 72%, although the presence of local anaesthetic in the inguinal canal was significantly higher with the DS technique. The incidence of femoral nerve block was 4.5% with the SS and 9% with the DS technique ( P > 0.05). Parental satisfaction with postoperative pain relief was high, at 94%. Conclusions : The DS technique, while technically more difficult, does not improve the success rate of the IG–IH nerve block compared with the SS technique.
