How long should an affected leg be kept straight after cardiac catheterization?

After cardiac catheterization, keeping the affected leg straight for an appropriate duration is crucial to prevent complications such as bleeding or clots at the catheter insertion site. The correct duration of 4 to 6 hours allows sufficient time for hemostasis, where the blood vessel can seal properly after the catheter is removed.

This timeframe ensures that any potential bleeding is minimized while still allowing for postoperative monitoring. Depending on the patient's age, size, and individual response, this range effectively balances safety and comfort. It's essential for healthcare providers to follow protocols that rely on evidence-based practices to ensure optimal recovery and reduce the risk of complications after such invasive procedures. Keeping the leg straight beyond this time frame may not provide additional benefits and could be uncomfortable for the child.
