What should I expect?

• The nerve block catheter will not take away all of your pain. But, you will not need to take as many pain pills while it is working.
• The leg where the catheter is placed will be numb and may be very weak. You may not be able to put all your weight on it.
• Over time, the pump will slowly lose its shape and flatten. This will take several days, depending on what pump size you have. When the pump is empty, you will see a hard core inside.
• A team member will call you each day while your catheter is in place to make sure it is working safely.
• Do not change the flow rate dial unless your doctor tells you to.

Self-Care

• Always protect your leg that has the nerve block. Be careful with hot, cold, hard, or sharp surfaces. You can easily get hurt since your leg does not feel pain or pressure.
• Be careful when you move. Your balance may be affected.
• Do not pull on the catheter.
• Always have someone help you when you stand or walk while you have this nerve block. Wait until the therapy is stopped and you have regained full feeling and strength in your leg before you try to stand or walk by yourself.
• Always use assistive devices such as a knee immobilizer, crutches, or a walker during any walking or standing activities.
• Follow your doctor’s instructions about positioning and activity.
• Keep the catheter insertion site and bandage dry.

How does the catheter come out?

When the pump is empty, follow these steps to remove the catheter:

• Sit down.
• Take off the dressing over the catheter. Do not use scissors.
• Firmly grasp the catheter near your skin. With gentle, steady pulling, slide it out from your skin. The catheter should come out easily. You should feel very little or no discomfort.
• If you feel any sudden sharp pain when you begin to pull, stop. Call us for instructions (see phone numbers in the “Questions” box).
• After you remove the catheter, check the tip for a black mark. Call your provider if you do not see the black mark.
• Then place the catheter and pump in the trash.
• You may place a small bandage over the spot where the catheter was.
