Saline Lock: Care Instructions

Your Care Instructions

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 I.V.).

The doctor or nurse puts the medicine through the lock and into your vein. This is more comfortable for you, because you won't be stuck with a needle every time you get medicine. In between medicine doses, the lock closes, so no germs can get into the tube and vein.

You will have the saline lock for a few days. You will be told how you will get your medicine. You may be asked to go to your doctor's office, the hospital, or a special clinic. Or a nurse may come to your home. When the treatment is finished, the doctor will take out the lock.

The doctor has checked you carefully, but problems can develop later. If you notice any problems or new symptoms, get medical treatment right away.

How can you care for yourself at home?

• 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.
• Wash the area around the lock daily with warm water, and pat it dry. Don't use hydrogen peroxide or alcohol.
• You will have a dressing where the lock goes into your skin. A dressing helps protect the lock. Your doctor will tell you how to take care of it.
• Do not do any exercise that involves the arm or hand with the lock.
