AbstractThe aim of this study was to compare the efficacy of femoral nerve block with indwelling catheter-based multiple infiltrations of bupivacaine for postoperative pain management after iliac bone harvesting. Sixty paediatric patients undergoing iliac harvesting were randomized into three groups: group A, preoperative femoral nerve block; group B, multiple bolus infiltration of 0.5% bupivacaine via indwelling catheter at the donor site; group C, controls--single dose of 0.5% bupivacaine infiltration given subcutaneously. The primary outcome measure was postoperative pain intensity at rest and at function. The time to maximum pain score, time to ambulation, duration of analgesia, and length of hospital stay were also assessed. Group B patients had the best pain relief and return to function, however the duration of pain relief was longer in group A. Subjects in group A had concomitant motor blockade causing delayed ambulation. Group C showed the worst outcomes. Indwelling catheter-based infiltration of bupivacaine was the most efficient method for providing enhanced pain relief after iliac bone graft harvesting. There was no increase in operating time or hospital stay. Femoral nerve block provided the next best results, but had the significant disadvantage of motor nerve blockade.Copyright © 2013 International Association of Oral and Maxillofacial Surgeons.
