Abstract
To determine whether scheduled low-dose, short-term ketorolac is associated with reduced length of stay, opioid use, and pain in orthopaedic polytrauma patients. Double-blinded, randomized controlled trial. One Level 1 trauma center. From August 2018 to October 2022, 70 orthopaedic polytrauma patients between 18 and 75 years of age with a New Injury Severity Score > 9 were randomized. Seventy participants were enrolled, with 35 randomized to the ketorolac group and 35 to the placebo group. The intervention used was 15 mg of intravenous (IV) ketorolac every 6 hours for up to 5 inpatient days or 2 mL of IV saline in a similar fashion. Length of stay (LOS), morphine milligram equivalents, visual analog scale, and complications. Study groups were not significantly different regarding age, body mass index, and New Injury Severity Score ( P > 0.05). The median LOS was 8 days (interquartile range, 4.5-11.5) in the ketorolac group compared with 7 days (interquartile range, 3-10) in the placebo group ( P = 0.275). Over the 5-day treatment period, the ketorolac group experienced a 32% reduction in average morphine milligram equivalents ( P = 0.013) and a 12-point reduction in baseline-adjusted mean visual analog scale ( P = 0.037) compared with the placebo group. There were no apparent short-term adverse effects in either group. Scheduled low-dose, short-term IV ketorolac was associated with significantly reduced inpatient opioid use and pain in orthopaedic polytrauma patients, with no significant difference in LOS and no apparent short-term adverse effects. The results support the use of scheduled low-dose, short-term IV ketorolac for acute pain control among orthopaedic polytrauma patients. Further studies are needed to delineate lasting clinical effects and potential long-term effects, such as fracture healing. Therapeutic Level I.
