The ON-Q system is a small disposable pump filled with a local anesthetic medication to relieve your pain after surgery. It continuously delivers the medication, which blocks the pain in the area of your procedure. With the ON-Q system, you may get better pain relief than by taking narcotics alone.
The On-Q pump is placed by Dr. Jamieson during surgery. He places a catheter in the adductor canal near the sapheonus nerve. This catheter is then hooked up to a pump filled with numbing medicine. This medicine drips right by the nerve and lasts about 48-72 hours. The home health nurse will pull the catheter when the pump is empty.
