The On Q Pump, also commonly called the On Q Pain Pump or the On Q PainBuster, is a medical device implanted in a patient’s body during surgery to alleviate post-operative pain. The On Q Pump works by infusing pain medication directly into the surgical site through a catheter continuously for up to 5 days. The On Q Pump is prescribed by surgeons to patients undergoing a range of general surgery procedures, including:

  • ACL knee surgery
  • Cesarean section
  • Gastric Bypass
  • Breast Augmentation
  • Arthroscopic shoulder surgery

On Q Pump Models

Distributed by the California-based I-Flow Corporation, the On Q Pump is available in four models, all of which are single-use and disposable:

  • ON-Q: has a fixed flow rate that cannot be changed and comes in single, dual, and triple site configurations
  • ON-Q with ONDEMAND: gives a continuous infusion of pain medication and allows fixed boluses of pain medication to be delivered on demand
  • ON-Q with Select-A-Flow: has an adjustable rate controller that allows the user to adjust the flow of medication
  • ON-Q with Select-A-Flow and ONDEMAND: includes the rate controller and the bolus device

Link Between On Q Pump and PACGL

The American Academy of Orthopedic Surgeons released a study in 2006 which described the link between pain pump use after arthroscopic shoulder surgery and the development of Postarthroscopic Glenohumeral Chondrolysis (PAGCL), a painful condition in which hyaline cartilage in the shoulder joint wears down.

In that study, twelve of 152 arthroscopic shoulder surgery patients examined in a three-year period developed PAGCL (in other words, about 8% of the patients studied developed PAGCL). The only factor that these 12 patients had in common was their treatment with a shoulder pain pump, such as the On Q Pump.

According to another study, which was published in the October 2007 issue of The American Journal of Sports Medicine, as much as 63 percent of patients who use shoulder pain pumps, like the On Q Pump, are at risk of developing PAGCL. Due to the high risk of PAGCL, this study’s authors recommended that shoulder pain pumps, such as the On Q Pump, should not be used until their effects are further studied.
