Analgesic Efficacy After Umbilical Hernia Repair in Children

Umbilical hernia repair, a common Day Surgery procedure in children, is associated with considerable postoperative discomfort. The patient has to meet certain discharge criteria such as tolerating liquids, adequate level of analgesia, etc., prior to being discharged from the day surgery unit. Currently, both rectus sheath block and local infiltration of the surgical site are used for providing post-operative analgesia for umbilical hernia repair surgery. The local infiltration can only be done at the end of the surgical procedure as it could alter the planes of the surgical field if performed preoperatively. We believe that the analgesia provided prior to the surgical incision will decrease the amount of intraoperative and postoperative opioids used and the subsequent side effects of these medications (5,6). The rectus sheath block, a regional anesthetic technique, offers possible improved pain management following umbilical hernia repair in a recent observational study (1-3,7). We will perform a double-blinded, randomized study to compare the efficacy of rectus sheath block and surgical infiltration in providing postoperative analgesia.
