A saline lock (SL), also known as a heparin lock, is a peripheral intravenous cannula connected to extension tubing with a positive pressure cap (see Figure 8.7). This device allows easy access to the peripheral vein for intermittent IV fluids or medications (Perry, et al., 2014).
How long can you have a saline lock?
Because the IV Saline lock provides direct access to your bloodstream, there will be a dressing placed over the site to keep it clean and minimize the risk of infection. You may have this IV Saline lock for up to 72 hours, at which time it must be removed.
Is saline lock same as IV?
The saline or heparin lock is a type of venous access. It is more commonly known as an IV or an intravenous catheter. Saline locks are routinely used for most women when they are admitted to the hospital in labor. Having this IV or saline lock in place allows for immediate access to your vein.
Do you need a prescription for a saline lock?
A peripheral IV may be converted to a saline lock when a prescribed continuous IV therapy is switched to intermittent IV or a saline lock for future use. A physician’s order is required to stop a continuous infusion.
Why do you saline lock an IV?
It helps prevent the IV from getting blocked with a blood clot. It’s called a saline lock because a small cap is placed at the end of the catheter (the thin, sterile tube part of the IV) to keep the saline inside. You’ll have a saline lock for as long as you need to take medicines through an IV.
Can you shower with a saline lock?
While you have the lock, take showers instead of baths, and don’t swim. Keep the lock dry. When you shower, cover the site with waterproof material, such as plastic wrap. This helps prevent infection.
Why are heparin flushes no longer used?
Heparin solution should never be used because extra inadvertent doses of heparin through the intravenous lines can lead to adverse drug events, especially when patients are receiving other anticoagulant therapy or are at risk for bleeding.
How often do you change a saline lock?
In general, saline locks are changed every 72 hours. If a patient has a peripheral IV in an area of flexion, the IV site should be replaced within 24 hours, or when the patient is stable.
What is the purpose of Heplock?
This medication is used to prevent and treat blood clots. It may be used to prevent and treat blood clots in the lungs/legs (including in patients with atrial fibrillation). It may be used to treat certain blood clotting disorders.
