Summary

Paravertebral block (PVB) might be a technique of choice for hernia surgery due to its unilateral segmental anesthesia of the operative site, good muscle relaxation and prolonged postoperative analgesia. Despite PVB effectiveness, a continuing search for a reliable, timely and effective technique generates the investigation of a single PVB injection for children undergoing unilateral inguinal hernia repair. Two theoretical concepts were behind this investigation. First, possible spread of single PVB injection in the lumbar area over dermatomes corresponding to the inguinal hernia region in children likewise the spread over multiple adjacent segments from a single thoracic PVB injection. Second, as the inguinal region receives innervation from the ilioinguinal, iliohypogastric and genitofemoral nerves, all three arising from L1-L2 level; thus, a single PVB injection at this level could provide unilateral segmental anesthesia.

Conditions

  • Reduce Pain After Herniorrhaphy

Interventions

OTHER

Anesthesia induction

All patients will have inhaled induction of anesthesia by facemask using oxygen and 8% sevoflurane for 2 to 4 minutes followed by placement of an IV cannula. After performing PVB injections, the sevoflurane concentration will be decreased to 0.4% to 0.8% and maintained until completion of surgery.

OTHER

PVB injection at L1-L2

Patients will receive a single PVB injection at L1-L2 and placebo PVB injections at T12-L1 and L2-L3.

OTHER

PVB injections at T12-L1, L1-L2 and L2-L3.

Patients will have PVB injections at T12-L1, L1-L2 and L2-L3.
