The control of postoperative pediatric pain after hernia repair is achieved with a combination of oral and intravenous pain medications and "nerve blocks". "Nerve blocks" are achieved by injecting local anesthetics or what is commonly referred to as "freezing "next to the nerve supply of the wound. "Freezing" the major nerves supplying sensation at the site of hernia repair in children, while they are asleep, is effective. At CHEO, this technique in addition to administering ketorolac, a liquid intravenous form of an anti-inflammatory agent similar to Advil, is the current technique of choice for postoperative pain control after inguinal hernia.
