How it works and what to expect
A nerve block uses local anesthetic to numb a specific area of your body and reduce pain after surgery. This procedure often helps you feel better faster, recover more comfortably and participate in physical therapy sooner.

The catheter and portable pump
A small catheter is gently threaded near the target nerve. After surgery, it’s connected to a portable infusion pump that can provide continuous local anesthetic for up to about 4 days. The balloon in the pump slowly deflates as medication infuses. You won’t need to adjust the pump.
Safety reminders
Because the area is numb, you may have muscle weakness and reduced sensation. Protect the limb and avoid bearing weight until advised.
At home pump and catheter care
- Keep the dressing clean and dry. Small clear or pink drainage can be normal, and leakage is not a concern if pain control is good
- Don’t change the dressing yourself. Reinforce with tape if needed
- Sponge bathe only while the catheter is in place. Keep the pump within roughly18 inches of the insertion site
- Use the provided carrying pack. Don’t drop the pump or get it wet
Removal steps (when your infusion ends)
- Gently lift the adhesive dressing
- Grasp the catheter near the skin and pull it out gently; a little discomfort or resistance is expected
- Hold pressure for 5 minutes; apply a Band-Aid and remove later that day
- Discard the catheter, tubing, and pump in the trash; do not attempt to remove leftover medication or inject it
- Any remaining numbness should resolve within about 24 hours; continue oral pain medications as directed
Frequently asked questions
How long does the pump last?
Often up to ~4 days, depending on your surgery and plan.
Can I shower?
No. A sponge bath is recommended while the catheter is in place.
What if pain isn’t controlled?
Check for kinks/closed clamps, confirm fluid remains, and call the number in your discharge instructions.
