What is a contraindication for using an Umbilical Artery Catheter (UAC)?

A contraindication for using an Umbilical Artery Catheter (UAC) is omphalitis, which is an infection of the umbilical stump. This condition poses significant risks, as inserting a catheter in an infected area can lead to further complications such as systemic infection, poor outcomes, or even sepsis. The presence of an infection creates an unsafe environment for catheter placement, increasing the likelihood of introducing pathogens into the bloodstream.

In contrast, congenital heart disease, premature birth, and low birth weight are not absolute contraindications for UAC use. Patients with congenital heart disease may require UACs for monitoring or blood gas sampling, and although premature infants and those of low birth weight appear more vulnerable, they can safely have UACs placed when done with careful consideration of their overall clinical status and the benefits versus risks.
