How to Run a Secondary IV Line?

Published in IV Administration 3 mins read

Running a secondary IV line, often called an IV piggyback, involves a specific process to ensure proper medication delivery. Here's a breakdown of how to do it safely and effectively:

Steps for Running a Secondary IV Line

The process generally involves these steps, based on the reference provided:

  1. Connect the Secondary Tubing:

    • Attach the secondary tubing to the port on the primary IV line that is closest to the drip chamber. This is crucial for ensuring the flow of the secondary medication.

  2. Lower the Secondary Bag:

    • Position the secondary IV bag below the primary IV bag.
    • This initial step is important to allow the primary IV fluid to prime the secondary tubing properly.

  3. Fill the Secondary Tubing:

    • Allow the fluid from the primary IV bag to flow into the secondary tubing.
    • Continue this process until the fluid reaches the drip chamber of the secondary line.

  4. Raise the Secondary Bag:

    • Once the secondary tubing is primed, raise the secondary bag above the level of the primary IV bag.
    • This reversal of position ensures that the secondary medication infuses into the primary IV line.

Important Considerations

When running a secondary IV line, keep these points in mind:

  • Compatibility: Always check the compatibility of the secondary medication with the primary IV fluid. Incompatible medications can cause precipitates and potentially harmful results.
  • Flow Rate: Ensure the secondary line is running at the prescribed rate. Adjust the clamp on the tubing if needed.
  • Monitoring: Closely monitor the patient for any signs of adverse reactions during the infusion.
  • Placement: Ensure the secondary bag is hung correctly and securely.
  • Air: Avoid introducing air into the IV tubing to prevent air embolism.

Visual Summary

Here's a simple table summarizing the process:

Step Action
1. Connect Tubing Attach secondary tubing to port nearest the drip chamber on the primary line
2. Lower Secondary Bag Place the secondary bag below the primary bag.
3. Fill Tubing Let primary IV fluid flow into the secondary tubing.
4. Raise Secondary Bag Position secondary bag higher than the primary bag.

By following these guidelines, you can ensure the safe and effective administration of secondary IV medications.
