Percutaneous Rectus Sheath Block Versus Intra-operative Rectus Sheath Block for Pediatric Umbilical Hernia Repair

After induction of anesthesia, the attending anesthesiologist will use a portable ultrasound probe to locate the rectus sheath. A 22 gauge needle will be used to inject a predetermined volume of 0.2% ropivacaine (1cc/kg, max dose 10cc, divided into equal doses bilaterally). The analgesic will be injected percutaneously using ultrasound guidance between the rectus abdominis muscle and the posterior rectus sheath at the lateral border bilaterally.

After the completion of the umbilical hernia repair, after fascial closure, but prior to skin closure, a predetermined volume of 0.2% ropivacaine (1cc/kg, max dose 10c, divided into equal doses bilaterally) will be administered under direct visualization into the rectus sheath bilaterally by the attending surgeon.
