Preoperative intravenous ibuprofen does not influence postoperative narcotic use in patients undergoing elective hernia repair: A randomized, double-blind, placebo controlled prospective trial

Abstract

Introduction: 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. This study sought to evaluate the efficacy of perioperative intravenous (IV) ibuprofen on postoperative pain level and narcotic use in patients undergoing open or laparoscopic inguinal and/or umbilical hernia repair. Methods: A single center, randomized, double-blind placebo-controlled trial involving patients ≥18 years undergoing inguinal and/or umbilical hernia repair was performed. Patients were randomized to receive 800 mg of IV ibuprofen or placebo preoperatively. Outcomes assessed included postoperative pain medication required and visual analog scale (VAS) pain scores. Results: Forty-eight adult male patients underwent inguinal and/or umbilical hernia repair. Patients receiving IV ibuprofen used more oxycodone/acetaminophen (32% vs 13%) and IV hydromorphone (12% vs 8.7%), and fewer combinations of pain medications (44% vs 65.2%) in the first two postoperative hours compared to placebo (p=0.556). The IV ibuprofen group had more patients pain free (28% vs 8.7%, p=0.087) and lower VAS scores (3.08±2.14 vs 3.95±1.54, p=0.134) at 2 hours postoperatively, compared to the placebo group, however, this was not statistically significant. Similar pain levels at 1, 3, and 7 days, postoperative and similar use of rescue medications in both groups were observed. Conclusion: Preoperative administration of IV ibuprofen did not significantly reduce postoperative pain among patients undergoing elective hernia repair. Considerable variability in postoperative narcotic analgesic requirement was noted, and larger scale studies are needed to better understand the narcotic analgesic requirements associated with IV ibuprofen in inguinal/ umbilical hernia repair patients.
