What is a contraindication for using an umbilical artery catheter?

A contraindication for using an umbilical artery catheter is associated with poor stump condition. When the umbilical stump is not in optimal condition, there is a higher risk for complications such as infection and improper placement of the catheter. A healthy stump is critical to ensure that the catheter can be inserted safely and securely, minimizing the risk of injury to surrounding tissues and achieving effective vascular access.

The other options do not represent contraindications:

• Blood sampling is a common practice with an umbilical artery catheter and is one of its intended uses.

• Continuous blood pressure monitoring is another valid use of the umbilical artery catheter, as it allows for real-time monitoring of a neonate’s cardiovascular status.

• Administration of fluids is also a typical function of this catheter, allowing for the delivery of necessary therapies.

Thus, ensuring that the umbilical stump is in good condition is vital before considering catheter placement, making poor stump condition a valid contraindication.
