What condition could contraindicate the placement of an umbilical venous catheter?

The placement of an umbilical venous catheter may be contraindicated by poor stump condition, as this could indicate an increased risk of infection or improper healing that could lead to potential complications during catheter placement. A poorly healed stump may also signal underlying issues with vascularity or perfusion in the area, making it less suitable for catheter placement.

In contrast, vascular compromise typically refers more to conditions affecting blood flow than to the status of the umbilical stump itself and may not be a direct contraindication if the vascular assessment shows otherwise viable access. Continuous blood pressure monitoring and blood sampling are routine procedures that do not inherently contraindicate the placement of a catheter.
