Intrathecal Drug Pump Implant

"Intrathecal pump" is the technical term for a device sometimes called a "pain pump." It delivers small amounts of medicine directly to your spinal fluid. This medicine is usually strong pain medicine, such as morphine or other opioid, or baclofen, a muscle relaxer.

Doctors use pumps to lessen the pain of unsuccessful back surgery, cancer, or nerve issues. They can also reduce spasticity, or muscle stiffness, in people with neurological health issues. 

Delivering pain medicines in small doses through an intrathecal pump helps reduce the side effects and mitigate risks associated with oral medications.

UPMC surgeons use the latest techniques and devices to treat your chronic pain. We reduce your side effects and symptoms while restoring your quality of life.

What Is an Intrathecal Drug Pump Implant?

An intrathecal pump is also known as a "pain pump." It delivers small quantities of pain medicines, such as morphine or other opioid pain, or baclofen, a muscle relaxer, directly into the spinal fluid.

The intrathecal pump is a metal device that stores and delivers the medicines. The medicines travel through a catheter (tube) into the space around the spinal cord.

Some pumps deliver a steady dose of medicine throughout the day. Other pumps are programmable — your doctor can set them to release the medicine over time or only at specific times of the day.

Types of intrathecal drug pump implants

There are two types of intrathecal drug pump implants:

  • Programmable pumps — Your doctor can set and adjust the dose and timing of your medicine. You receive a set amount at specific times of day.
  • Nonprogrammable pumps — You receive a steady dose of medicine throughout the day.

Conditions we treat with intrathecal drug pump implants

Intrathecal drug pump implants treat pain related to:

  • Brain injury.
  • Cancer.
  • Cerebral palsy.
  • Failed back surgery.
  • Multiple sclerosis.
  • Nerve pain.
  • Spasticity (muscle stiffness).
  • Spinal cord injury.
  • Stroke.

Why Would I Need an Intrathecal Drug Pump Implant?

You may need an intrathecal drug pump implant if you have chronic pain. It is an option if your pain is not relieved with other medicines or nonsurgical treatments. It is also an option if you have side effects caused by high doses of oral pain medicines. 

Who is a candidate for an intrathecal drug pump implant?

You may be a candidate for an intrathecal drug pump implant if you have severe chronic pain or spasticity. A pain pump is an option when these symptoms are not relieved with medicines or nonsurgical treatments and affect your ability to perform everyday activities. 

You may also be a candidate if you need to reduce your use of oral medicines due to side effects.

Alternatives to intrathecal drug pump implant

Depending on your health issue, surgery may help relieve pain. This would be an alternative to an intrathecal drug pump implant in some cases. In other cases, nonsurgical alternatives may help.

These include:

  • Heat or ice
  • Oral medicine to manage pain and other symptoms.
  • Physical therapy.
  • Steroid injections.

What Are the Risks and Complications of Intrathecal Drug Pump Implants?

To implant the pain pump, your doctor needs to do surgery. As with any surgery, an intrathecal drug pump implant comes with some risks.

Possible complications include:

  • Bleeding or infection at your incision site.
  • Blood clots.
  • Cerebrospinal fluid (CSF) leak.
  • Medicine withdrawal or overdose.
  • Nerve damage.
  • No improvement or a return of symptoms.
  • Problems with anesthesia.
  • Problems with the pump or catheter.

What is the downside of a pain pump?

Pain pumps can help you control chronic pain. But they can also increase your risk of medicine overdose or withdrawal.

To reduce your risk of these complications, you should:

  • Have your medicine refilled regularly and on time
  • Make sure you go to all your doctor visits.
  • Monitor your pump to make sure it is working properly.

What Should I Expect From Intrathecal Drug Pump Implant?

Before you get a permanent pain pump, your doctor may send you for an evaluation. This testing helps find out if the pump will improve your pain. 

During the evaluation, you will receive a test injection of medicine, sometimes called a trial intrathecal injection.

The doctor injects medicine into your spine during a procedure called a spinal tap. Another option is to perform a surgical procedure to implant a temporary intrathecal drug pump. 

If the medicine helps to reduce your pain level, your doctor may suggest a permanent intrathecal drug pump.  

Before: How to prepare for intrathecal drug pump implant

Before surgery, you will meet with your surgical team and have a physical exam. Your surgical team may order tests, such as:

  • Blood or urine tests — These studies ensure you are healthy enough for surgery. They also check for signs of illness or infection.
  • Electrocardiogram (ECG or EKG) — This test records the electrical activity of your heart. They show abnormal rhythms (arrhythmias or dysrhythmias) and can sometimes detect heart muscle damage. EKGs are often performed before surgery to check your heart health and identify potential problems.
  • MRI — This diagnostic procedure combines large magnets, radio frequencies, and a computer to produce detailed images of organs and structures within your body. Before DREZ lesioning, your surgeon will order an MRI to precisely locate the damaged spinal nerve roots.
  • X-ray — Your doctor may order an x-ray to learn more about the condition of the bones and tissues in your spine.

Your doctor will explain the procedure to you and answer your questions.

To prepare for the procedure, you should:

  • Fast for a certain period before the procedure. Your doctor will tell you how long to fast (usually overnight).
  • Have any tests that your doctor requires. For example, your doctor may request a blood test before surgery to find out how long it takes your blood to clot.
  • Tell your doctor if you are sensitive or allergic to medicines, iodine, latex, tape, or anesthetic agents (local and general).
  • Tell your doctor about all medicines (prescription and over-the-counter) and herbal or other supplements you are taking.
  • Tell your doctor if you have any other health conditions. Your care team may need to take certain precautions during surgery for your safety.
  • Tell your doctor if you have a history of bleeding disorders or if you are taking any medicines that affect blood clotting. You may need to stop some of the medicines before the procedure.

On the day of your procedure, bring your photo ID and health insurance card(s). Leave valuables such as cash and jewelry at home.

After your procedure, you may need to stay in the hospital, or they may discharge you the same day, depending on your doctor's assessment.

If you stay overnight, you should bring toiletries, a robe, slippers, a cell phone and charger, medicines, and a change of clothes. You should also arrange for someone to drive you home from the hospital after the care team discharges you.

How long does intrathecal drug pump implant surgery take?

Intrathecal drug pump implant surgery typically takes about two hours.

During your intrathecal drug pump implant surgery

When you arrive at the hospital, you will meet with your care team for final preparations. 

You will receive an IV and general anesthesia so that you will sleep through the procedure. Your anesthesiologist will ensure that you are comfortable and do not feel any pain.

After you are asleep, your surgeon will:

  • Make a small incision in your back to access your spine.
  • Insert a catheter into the space around your spinal cord.
  • Pass the catheter under your skin to the front of your body.
  • Implant the pump under the skin in your abdomen and connect it to the catheter.
  • Fill the pump with medicine.
  • Program the pump to deliver the correct dose of medicines at a specific time, if needed.

After your procedure, your surgeon will close your incision and make sure you are stable.

Recovery after intrathecal drug pump implant surgery

After your procedure, the care team will monitor you in the recovery area as you wake up. Depending on your doctor's assessment, you may need to stay overnight, or they may discharge you that day. You will need someone to drive you home from the hospital after the care team discharges you.

Before you go home, your doctor will tell you:

  • If needed, how and when to wear an abdominal binder to protect your pump.
  • How to care for your incisions and watch for signs of infection or complications.
  • What medicines to take.
  • When or if you should begin physical therapy.
  • When to call your doctor or 911 if you have certain symptoms.
  • When you can return to your normal activities.
  • Which movements are safe and which movements to avoid.

How long does it take to recover after intrathecal drug pump implant surgery?

Most people recover from intrathecal drug pump implant surgery in six to eight weeks.

How long does an intrathecal drug pump last?

A doctor permanently implants the intrathecal drug pump into your body. They can only remove it with another surgery. You will need regular visits with your doctor to refill your pump with medicine and adjust your dose.

Because the pump is battery-operated, you will need another surgery to replace the battery. Your surgeon will let you know how long your pump battery should last. Most batteries last five years or more.

When to call your doctor about post-op problems

You should let your surgeon know if you have:

  • A fever of more than 100.0°F.
  • Difficulty breathing.
  • Difficulty walking or keeping your balance.
  • New or increasing shortness of breath.
  • Numbness, tingling, pain, or weakness in your arms or legs.
  • Pain, redness, bleeding, drainage, or increased swelling at your incision site.
  • Severe pain that does not respond to medicine.

What is the prognosis after intrathecal drug pump implant surgery?

Most people can live full and active lives after intrathecal drug pump implant surgery.

What is the success rate of intrathecal drug pump implant surgery?

More than 90% of people experience pain relief after an intrathecal drug pump implant.
