CADD® Solis pump for nerve block infusions


What is the CADD® Solis pump?

The CADD® Solis pump infuses a medicine called an anesthetic that lessens the feeling of pain. Using this pump will help your child feel less pain after surgery. It also might help your child need less pain medicine.

How does the CADD® Solis pump work?

The pump is attached to a catheter (small tube) that is placed under the skin next to a nerve near the area of the body where your child had surgery. The pump delivers the medicine at the prescribed rate, blocking the pain where your child had surgery.

The pump is portable and comes in a travel bag to make it easier for your child to move around with the pump.

How do I know the pump is working?

The pump is infusing when the green light on the left side of the screen is flashing and the bar at the top of the screen is green and reads RUNNING. The infusion is not running if an amber (orange) light is flashing to the left of the screen and the bar at the top of the screen is red with the word STOPPED.

How do I start and stop the pump?

To start or stop the pump:

  • Press the stop/start key.
  • When you see the message “Stop pump?” press Yes or No.

How do I know if a blockage is keeping the pump from giving the medicine?

The pump will alarm to tell you if the tubing is kinked or clamped. The screen will say “downstream occlusion. Clear occlusion between pump and patient.” If you unkink or unclamp the tubing, the alarm sound will stop and the pump will automatically start running as it had before. Until you can find the problem and correct it, the alarm sound will continue and your child will not receive medicine from the pump. To stop the alarm, turn off the pump and remove the batteries. If you cannot find the problem causing the alarm, you will need to call the pain management doctor as soon as you can for further directions.

How do I care for my child with this pump?

If your child is having too much pain or cannot move an arm or leg, you should tell the anesthesiologist within the next few hours and arrange to come to St. Jude.  If your child is an inpatient, a doctor or nurse will make any needed changes to the pump. If your child is an outpatient, dial 901-595-3300 and ask for the anesthesiologist on call. Tell the St. Jude operator that your child has a nerve block infusion, and you must talk to the doctor right away.

The dressing covering the area where the catheter is inserted into the skin should be kept clean and dry. If the dressing becomes wet or loose, call your child’s doctor or nurse within a few hours. Bathing is fine as long as the pump and the dressing stay dry.

How do I know when to change the batteries?

If a message on the screen says “Battery low, replace battery,” you will need to replace the batteries as soon as you can.

How do I change the batteries?

To change the batteries, follow these steps:

  1. Press the stop/start button.
  2. “Stop pump?” displays. Press Yes.
  3. Remove the 4 used batteries.
  4. Insert 4 new AA batteries.  Do not use rechargeable NiCAD or carbon zinc (“heavy duty”) batteries as the pump will not work properly with those kinds of batteries.
  5. Press the power switch to turn on the pump.
  6. The screen displays “Do you want to start a new patient?” Press No.
  7. Press stop/start to start the pump.
  8. “Start pump?” displays. Press Yes.
  9. If you do not change the batteries while they are low, the alarm will sound and the amber (orange) light will no longer flash. Change the batteries as described above.

How do I know if there is a problem with the medicines being used?

Certain side effects are rare but they can be the signs of a serious problem. If your child has any of the following symptoms, close the clamp on the pump tube right away and call your child’s anesthesia doctor.

  • Ringing, buzzing in the ears
  • Metal taste in the mouth
  • Numbness or tingling around the mouth
  • Redness, swelling, pain, or discharge (fluid) where the catheter is placed
  • Feeling dizzy or faint
  • Blurred vision
  • Confusion

To reach the anesthesia doctor, dial 901-595-3300 and ask for the anesthesiologist on call. Tell the St. Jude operator that your child has a nerve block infusion, and you must talk to the doctor right away.

Call 911 right away if your child is having problems breathing or if there is a medical emergency.

When will the catheter be removed?

The catheter can stay in place up to a week after surgery but might be removed sooner if needed. When all the medicine has been given, your child will have a new bag connected in the clinic or it may be time to remove the catheter. The catheter can be removed in the clinic by the anesthesiologist or pain nurse.
