Peripheral Nerve Catheter and Pump (PNC) for Pain - Outpatient

Helping Hand Logo

Peripheral nerve catheter.

The doctor has placed a flexible tube (catheter) under your child’s skin to help control his or her pain. The tube is called a peripheral (pa RIF e rel) nerve catheter (Picture 1). One end of the tube is under the skin around the nerves. The other end is attached to a pump. The catheter is placed either while your child is asleep in the operating room or under sedation, before he or she goes into the operating room.

The pump is filled with numbing medicine. The medicine goes through the tube and numbs the nerves that send pain signals from the area of surgery to the brain. This blocks the feeling of pain. The medicine from the pump may be enough to manage the pain. Or, your child can also take the pain medicine his doctor ordered for him if needed.

Common Side Effects

The medicine may make the arm or leg feel weak, heavy or tingly and numb.

The feeling will stop after the numbing medicine wears off. Your child may not be able to move the area for one or two days after surgery.

Be sure to protect the arm or leg from injury during this time. Have your child test using his arm or leg before using it or putting weight on it. When the numbness wears off, there may be more pain.
