Overview

A saline lock is a thin, flexible tube placed in a vein (called an intravenous, or I.V., line) in your hand or arm. It sticks out a few inches. The lock is used when you may need to get medicines or fluids.

Having a saline lock is more comfortable than being poked with a needle every time you get medicine or fluids. When the lock is not being used, it is closed so no germs can get into the tube and vein.

You will have the saline lock for a few days. 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 saline lock will be taken out.

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

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

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 holds the lock in place and protects the skin. You will get instructions on how to take care of it.
• Do not do any exercise that involves the arm or hand with the lock.

When should you call for help?

Contact your doctor now or seek immediate medical care if:

• There is liquid leaking from around the lock.
• There are cracks or leaks in the lock.
• You have symptoms of infection, such as:
  • Increased pain, swelling, warmth, or redness around the area.
  • Red streaks leading from the area.
  • Pus draining from the area.
  • A fever.

Watch closely for changes in your health, and be sure to contact your doctor if you have any problems.
