Elastomeric Pump Reliability in Postoperative Regional Anesthesia: A Survey of 430 Consecutive Devices

Abstract

In vivo reliability of elastomeric pumps is different than in vitro. In the event of early insufficient postoperative perineural analgesia, an absence of deflation of the elastomeric pump must be considered. We recommend weighing these devices every 3 h during the first 24 h of infusion.
