Inguinal and umbilical hernia repairs are among the most common surgical procedures performed in the US. Optimal perioperative pain control regimens remain challenging and opioid analgesics are commonly used. Preoperative nonsteroidal anti-inflammatory drug (NSAID) administration has been shown to reduce postoperative narcotic requirements. A single center, randomized, double-blind placebo-controlled trial was conducted on patients undergoing inguinal and umbilical hernia repair. One group received the intravenous NSAID and the other group did not. One outcome measured was postoperative pain medication required and the comparison of the postoperative analgesic requirements among patient groups receiving intravenous ibuprofen or placebo.
