Perineural Pain Pump for Leg Surgery
Perineural Pain Pump for Leg Surgery
To help control your pain after surgery, a small tube called a catheter was placed under your skin near your incision. The tube is connected to a pain pump filled with numbing medicine. The medicine numbs the nerves that send pain signals from your leg to your brain, so you have less pain. Perineural means around the nerves.
Your leg may feel numb, and you may not be able to move it until the day after your surgery. Be sure to protect your leg during this time. As the numbness wears off, the medicine from the pump will help control the pain. You can also use the pain medicine ordered by your doctor if needed.

Common side effect
This medicine may make your leg weak, causing a high risk for falling. Use touch weight bearing on your surgery leg while using the pump and for 3 hours after the pump is removed. This means when you stand or walk, you may only touch the floor for balance with the ball of your foot.
Leak at the tube site
A small amount of fluid leaking from the tube site is common.
Call your doctor if:
- The tube comes out of your skin.
- The fluid leaking is not clear in color.
- Your dressing is so wet it starts to come off.
When the pump is empty
The pump will get smaller and flatten as it empties. You will be able to feel a hard tube in the middle of the bulb and the bulb looks like a balloon that has lost air.
Remove the tube when the pump is empty, or at bedtime on __________________, whichever comes first.
Removing the tube
- Wash your hands well with warm water and soap. Rinse and dry with a clean towel.
- Remove the clear dressing by peeling it back from an edge. Loosen it around the site where the tube goes into the skin.
- Hold the tube close to the skin and gently pull. The tube should come out easily. The end of the tube should have a colored tip, so you know it is all out. You do not need to cover the site.
- Throw the tube, pump, and dressing into a trash bag.
- Wash your hands again with warm water and soap.
- Check the site the next day. If you have redness, pain, or warmth at the site, call your doctor.

- Redness or pain at the site where the tube goes into your skin
- Numbness around your lips
- Blurred vision or dizziness
- Ringing in your ears or a metal taste in your mouth
