Ultrasonography-guided bilateral rectus sheath block vs local anesthetic infiltration after pediatric umbilical hernia repair a prospective randomized clinical trial ultrasonography-guided brsb in children

JAMA Surgery, 06/24/2013

To compare efficacy of ultrasonography–guided BRSB and local anesthetic infiltration (LAI) in providing postoperative analgesia after pediatric umbilical hernia repair. In the PACU, ultrasonography–guided BRSB after umbilical hernia repair in children is associated with lower median FACES scores and decreased use of opioid and nonopioid medications compared with LAI. Future studies could examine the use of longer–acting anesthetic agents with ultrasonography–guided BRSB.
