title: Arthrex AR-6400 and AR-6475 arthroscopy pumps can deliver excessive pressure without alerting user.
abstract: Under certain conditions, Arthrex AR-6400 and AR-6475 arthroscopic irrigation/distention pumps can create pressures within the patient's joint that are more than twice the desired pressure without alerting the clinician, increasing the potential for serious patient injury due to extracapsular solution infiltration. Facilities need to thoroughly understand the behavior of these pumps and determine whether the clinical benefits of using them outweigh the solution-infiltration concerns. If your facility is not comfortable with the behavior of these pumps, use an alternative pump.
