Inaccuracy of Urine Output Measurements due to Urinary Retention in Catheterized Patients in the Burn ICU

摘要

ObjectiveElectronic Urinary Output Monitors (eUOMs), intended to provide urine output information to guide fluid therapy during burn resuscitation, can be inaccurate due airlocks causing urine retention in the drainage tube and bladder. In this study, we explore the effects of airlock formation on urine output measured using an eUOM connected to either a standard commercial drainage tubing system or a drainage tubing system with an automated airlock clearing mechanism.
