Intrathecal Pumps in Colorado
You Still Have Options When Conventional Treatments Fail
Pain is one of the most common reasons people visit their doctors. When
pain is persistent, and causes a physical disability, it is considered
to be chronic pain. According to some international studies, around 20%
of the general population are afflicted with chronic pain. In the U.S.,
25% of people have recurring, chronic pain, and around 2/3rds of these
people have had the pain for more than five years. An intrathecal pain
pump is used when the patient has persistent pain despite conventional
Who needs intrathecal pain medicine?
There two types of patients who can benefit from this treatment: patients
suffering from terminal illnesses, such as cancer, and people with non-malignant
chronic pain. This treatment is typically only recommended for patients
who have not responded conservative therapies, who have no active addiction
issues, and who have passed psychological testing.
What is an intrathecal pump?
The intrathecal pump is a small device that is surgically implanted under
the skin. This device has a tiny battery-powered pump that is programmable
and refillable. The nurse refills the pump every 1-3 months using a syringe
and needle. The pump is connected to an intrathecal catheter that delivers
tiny concentrated amounts of pain medicine to the spinal fluid.
How is the intrathecal pump implanted?
Before the permanent device is implanted, the pain management specialist
will have you take an epidural trial. This means the catheter tip is placed
in the epidural space, but the pump is worn outside the body. The doctor
then checks to see if you have at least 50% improvement in pain scores
during the trial before the pump is surgically placed in the body.
When you have surgery, a small incision is made over the skin of the lower
abdomen, and the pump is placed just under the subcutaneous tissue. The
catheter is connected to the pump, and the incision is closed using sutures.
What can I expect after the procedure?
The intrathecal pump implantation procedure is done under general anesthesia,
so you will have no memory of the event. The incision sites of the lower
abdomen and spinal region will be tender, and you may have some mild discomfort.
A remote device is used to deliver the medication, which you carry with
you. When you awake from surgery, you will be dizzy, drowsy, and may have
nausea. After you become alert, the nurse will give you something to eat/drink,
and have you sit up. We recommend that you rest for 2-3 days and slowly
resume your regular day-to-day activities.
What medications are used in the intrathecal pump?
For pain relief, the doctor may fill the pump with local anesthetics, adrenergic
agonists, opioids, and other agents. The first line treatment for severe
pain is morphine and hydromorphone. Other drugs used include Fentanyl
Does the intrathecal pain pump work?
According to a recent study involving methadone in the pain pump, the intrathecal
delivery system offered an 80% efficacy rate. A double-blind randomized
clinical study involving 24 patients found that patients had improved
quality of life when bupivacaine was added to their opioid agent in the
