Educational Pearls:

  • Randomized controlled-trial evaluated intradermal injections of sterile water to manage low back pain versus an IV NSAID
  • Four intradermal injections of 0.1 cc sterile water in a square around the area of musculoskeletal pain
  • Reduction of pain was 7 points with the procedure and 2 points with the IV NSAID at 24 hours
  • 12% in the injection group versus 50% in the IV NSAID group needed opioids
  • 87% patient satisfaction in the injection group versus 16% patient satisfaction in the IV NSAID group
