Liver fluid collection in neonates and its association with the use of a specific umbilical vein catheter: Report of five cases

Abstract

In newborns, the presence of liver fluid collection is a rare event. The reported cases are isolated or described over long periods. Within four months, five neonates were diagnosed with liver fluid collection from safety occurrence reports. Clinical, laboratory and radiological data were extracted from medical records. The definite diagnosis was made by ultrasound. Four of the patients were preterm, male and had very low birth weights. The osmolality of the infused solution was within the acceptable range. Investigations revealed that the use of a new brand of umbilical vein catheter introduced in the neonatal intensive care unit, one month before the first case, was associated with this cluster. Low positioning of the umbilical vein catheter tip appeared to be a second contributory factor. Neonatal practitioners may benefit from the present report when facing the occurrence of similar lesions.
