Comparison of ropivacaine with bupivacaine and lidocaine for ilioinguinal block after ambulatory inguinal hernia repair in children.
BACKGROUND
We have compared ropivacaine with bupivacaine and lidocaine for ilioinguinal block in thirty children undergoing ambulatory inguinal hernia repair.


METHODS
Patients were assigned randomly to receive 0.5 ml.kg(-1) of 0.2% ropivacaine (Group R, n = 10), 0.25% bupivacaine (Group B, n = 10) or 1% lidocaine (Group L, n = 10). The patients' parents, who were not informed of the type of local anaesthetic employed, evaluated the postoperative pain at 2 h and 6 h after operation using the Wong-Baker FACES Pain Rating Scale.


RESULTS
There was a significant difference in the face scale score between Group R and Group L, and Group B and Group L. There was no difference in the face scale score between Group R and Group B. There were no complications or clinical evidence of local anaesthetic toxicity.


CONCLUSIONS
We have confirmed that bupivacaine and ropivacaine are more effective than lidocaine in the prevention of postoperative pain after children's inguinal hernia repair. We suggest that ropivacaine 0.2% is an alternative to bupivacaine 0.25% for ilioinguinal block in ambulatory paediatric surgery.
