A saline lock is an IV catheter that is inserted in a vein, flushed, and capped. Saline itself is a special mix of water and sodium chloride. This is part of basic medicine when it comes to treating patients who need this IV.

When inserting the needle, a doctor or nurse should know that the needle has penetrated the vein and not just the skin. The saline lock includes an IV catheter, chloraprep swab, tourniquet, tape, Tegaderm transparent dressing and gauze, a 10 mL saline flush, IV extension tubing, and a pen.

First, connect the extension tubing to the catheter and attach the saline flush to the end of the tube. Squeeze a bit of saline out until a few drops come out, preventing any air from being part of the insertion. (Air embolism is possible and can kill the patient.)

Find a vein in the arm; put the tourniquet on 3 to 4 inches above where you will insert the needle and have it on tight, as it will make it easier to insert the needle into the vein. Get the swab and rub it on the targeted insertion spot to remove bacteria.

Tell the patient to remain still as the needle is inserted at a 30-degree angle; if there’s a mistake to which you have to pull the needle, you have to redo the whole process and get a new needle. (This is a safety precaution.) When blood is drawn, also known as a “flashback,” insert the needle in about 1/8 – ¼ inches more. Once the catheter is stable, remove the needle, put it in a needle container, and attach the flush to solidify the catheter in the vein. Don’t force it in.

Finally, put dressing over where the catheter was inserted and label the name, date, time on there.
The purpose of all of this is to keep the blood moving despite having medication inserted and prevents any blood clotting. This is one of the most important and common procedures done in hospitals. All doctors and nurses should be able to perform this function to someone.
