Frequently Asked Questions

What is a saline lock?

A saline lock is a thin, flexible tube placed in a vein in your hand or arm. It sticks out a few inches. The lock is used when you may need to get medicines through a vein (intravenous, or IV). The doctor or nurse puts the medicine through the lock and into your vein.

What is the difference between a heparin lock and saline lock?

The main difference between a heparin lock and a saline lock lies in the solution that prevents the IV from clotting. A hep-lock IV includes a solution of a blood thinner called heparin instead of saline. Heparin is an anticoagulant that thins the blood and prevents blood clots. The appearance of a heparin lock is the same as a saline lock.

How long can a saline lock be left in a vein?

Once the saline lock is inserted, it can be left in a vein for up to 72 hours or as per agency policy. Saline locks are usually inserted in the arm or hand. If a saline lock is removed, the extension tubing and positive pressure cap are also changed (Vancouver Coastal Health, 2012).

Should I use a saline lock during labor?

Talk to your doctor or midwife before your labor starts to clarify how they use saline IV locks and express your preferences. The benefit of a saline lock is that it provides immediate access in the case of emergency, but it really doesn't get in your way during labor.
