It is a refill of pain medication into the implanted pump reserve. The system uses a small pump that is surgically placed under the skin of your abdomen and delivers medication through a catheter to the area around your spinal cord.
What is the purpose of it?
To refill your pain medication.
How long does the injection take?
The actual injection only takes a few minutes, but plan to be in the office for one to two hours. This allows for your pre-op and recovery time as well. Your driver must remain in the building during your procedure.
What is actually injected?
The injection consists of a mixture of opioid and anesthetic medications.
Will the injection hurt?
The procedure involves inserting a needle through the skin and deeper tissue (like a tetanus shot). So, there is some discomfort involved. However, we numb the skin and deeper tissues with a local anesthetic using a very thin needle just prior to inserting the needle into the pump. Some patients opt to receive IV sedation, which makes the procedure easy to tolerate.
Will I be “Put Out” for this procedure?
No. This procedure is done under local anesthesia. If you do not feel comfortable with just the numbing medication, we give you the option of intravenous sedation. The amount of sedation given generally depends upon the patient’s tolerance.
How is the refill performed?
The procedure is done with the patient lying on their back under live x-ray. The patient is monitored with an EKG, blood pressure cuff and blood oxygen- monitoring device. The abdomen is cleaned with antiseptic solution and then the refill is carried out.
What should I expect after the injection?
You may feel sore for two to three days and/or may have increased pain. This is due to the mechanical process of the needle insertion.
What should I do after the procedure?
You should have a ride home after the procedure. We advise patients to take it easy the day of the procedure. You may apply ice to the affected area and perform activities as tolerated.
Can I go back to work the next day?
Yes, you should be able to return to work unless the procedure was complicated
How long does the refill last?
Each pump has different size reservoirs, but most refills will last approximately 3 months.
What are the risks and side effects?
Generally speaking, this procedure is safe. However, with any procedure there are risks, side effects, and possibility of complications. The most common side effect is pain – which is temporary. The other risks involve infection, bleeding, over medication, under medication, etc.
