Severe Peripheral Edema During an OutpatientContinuous Epidural Morphine Infusion Trial ina Patient with Failed Back Surgery Syndrome

Abstract

Peripheral edema may occur and persist during epidural morphine infusion. This report represents the first case report, to the best of our knowledge, describing severe peripheral edema in an otherwise healthy patient while on epidural morphine administration during an outpatient epidural morphine infusion trial. This case report shows that continuous epidural morphine infusion, even in small dose, may cause peripheral edema in some patients.
