Intrathecal Pump Treatment

What Is a Pain Pump?

The spinal cord and spinal cord nerves receive pain signals and send them through the body. With an intrathecal pain pump, medication is delivered directly, bypassing the path that oral medications take. This direct delivery treats pain symptoms more effectively with fewer body-wide side effects. Here is a breakdown of the components and mechanisms involved to help you make an informed decision:

Components of the Intrathecal Pump System

The intrathecal pump system is an implantable pain pump consisting of two main components: the pump and a catheter. The pump is a small, programmable device that stores and releases medication. It is typically implanted under the skin in the abdominal area. The catheter is a thin, flexible tube that connects the pump to the intrathecal space in your spinal cord, where it delivers the medication directly.

Medication Delivery Mechanism

Patients who have an intrathecal pain pump will not have to remember to take their oral medications because the pump will self-administer. The pump is programmed by our providers to release specific amounts of medication at predetermined intervals. Once activated, the device steadily delivers the prescribed medication through the catheter into the intrathecal space. This targeted approach allows the medication to interact directly with the spinal cord's pain receptors, providing effective pain relief with minimal side effects.

Advantages of Targeted Drug Delivery

Targeted drug delivery through an implantable pain pump offers several advantages over traditional oral medications, such as:

Candidates for Intrathecal Pump Treatment

Intrathecal pump therapy has the potential to transform the lives of chronic pain sufferers by providing targeted and effective pain relief for a variety of chronic pain conditions.

A few conditions that are often treated with intrathecal pumps are:

Evaluating Patient Suitability

To determine if intrathecal pump therapy is the right choice, our providers will consider several factors, such as the nature and severity of your pain and previous pain management treatments and their effectiveness. 

The factors that will be evaluated during a thorough consultation process include:

Review of Medical History

Your health history provides vital clues about your pain condition. We'll take the time to review your medical records, previous treatments, and any medications you're currently taking. It's crucial for us to understand the nature of your pain, its duration and intensity, as well as how it impacts your day-to-day life.

Physical Examination

A hands-on approach often reveals more than what meets the eye. Our doctors will conduct a detailed physical examination to assess your body's response to certain movements and pressures. This helps us identify specific areas of tenderness or discomfort which may be contributing to your chronic pain.

Diagnostic Imaging

To get a clearer picture of what's happening inside your body, we may use diagnostic imaging techniques like X-rays, MRIs, or CT scans. These advanced tools enable us to visualize potential sources of your pain, such as damaged discs, inflammation, or other structural issues that could be causing your discomfort.

Nerve Tests

Sometimes, it's necessary to delve deeper into the nervous system to pinpoint the source of your pain. If required, we'll conduct nerve tests to evaluate the function of specific nerves that might be involved in transmitting pain signals to your brain.

Diagnostic Nerve Blocks

In some cases, we may recommend diagnostic nerve blocks to help identify the exact source of your pain. Procedures like facet joint injections, epidural steroid injections, SI injections, or medial branch blocks can temporarily block pain signals from specific nerves. This can not only provide temporary relief but also help us determine whether an intrathecal pump implant might be a suitable treatment for you.

The Intrathecal Pump Trial

Potential candidates for a permanent pain pump will first have a trial procedure. This trial pump procedure helps determine if a patient is a good candidate for a permanent pump placement.

An intrathecal pain pump trial will also help determine the appropriate amount of medication it will take to treat a patient's symptoms. The titration or dosage information will establish the proper prescription to provide maximum pain relief and minimal side effects.

During this trial, medication is delivered into the intrathecal space through a temporary catheter, allowing our providers to monitor a patient's response to the treatment. If the trial proves successful in providing significant pain relief, the patient may proceed with the full implantation intrathecal pump surgery.

Pump trials are performed on an outpatient procedure and may last several days. The trial is considered successful if a patient experiences 50% relief or more from their pain symptoms. With a positive result from the pain pump trial, a patient can move forward with a permanent pain pump implant.

Intrathecal Pump Implant Procedure

After a successful trial, a patient can move forward with permanent intrathecal pump insertion. Our pain management doctors will implant the pain pump. The procedure is a minimally invasive surgery that takes about one to two hours and is usually done on an outpatient basis.

An overview of the pre-operative preparation, the procedure itself, and post-operative care for pain pump placement include:

Before the Procedure

Before the pain pump implant procedure, our providers will discuss the details of the surgery and answer any questions you may have. They will also provide specific instructions to prepare you for the intrathecal pump surgery, which might include:

The Procedure: Intrathecal Pump Placement

The intrathecal pump surgery typically involves:

Intrathecal Pump Surgery Recovery

Full recovery after intrathecal drug pump insertion may take one to three weeks. You will be limited to light activity, with some restrictions on your movement. Our provider will schedule a time for you to return for an intrathecal pump refill to refill the reservoir with more medication. During these visits, you will discuss your dosage effectiveness and any side effects you are experiencing.

Intrathecal Pump Refill Procedure

The intrathecal pump refill procedure is relatively straightforward and quick, often taking less than an hour. It is performed in our offices, and local anesthesia may be used to numb the area. Our specialist will use a special needle to access the pump's medication reservoir through your skin, and the spent medication will be withdrawn. Fresh medication is then refilled in the pump. The precise amount of medication is determined by your provider based on your specific needs.

After the procedure, our providers will do some intrathecal pump troubleshooting to make sure everything is working correctly by using a small device to communicate with the pump's internal computer. This procedure typically needs to be repeated every two to three months, depending on the dosage and capacity of the pump.

Intrathecal Pump Replacement

Intrathecal drug pumps are typically durable and built to last for several years. However, like any medical device, they are not designed to last forever. Over time, the battery in the pump will deplete, and the pump will need to be replaced. This is a routine procedure that is performed by a pain management specialist. It involves surgically removing and replacing the old pump with a new one. Throughout this process, the utmost care is taken to ensure minimal discomfort and maximal effectiveness of the new device. You can expect a recovery period similar to your initial pump procedure.

Potential Risks and Complications

As with any medical procedure, intrathecal pump therapy has potential risks and complications. Infection and bleeding are possible complications that may occur during or after the implantation procedure. To minimize these risks, our providers follow strict sterile techniques and may prescribe antibiotics as a preventive measure. Patients should also closely monitor their incision sites for any signs of infection or excessive bleeding.

Pump malfunction or migration is another potential concern. Although rare, issues such as mechanical failure or the pump shifting position within the body may require additional surgical intervention to address. Our specialists will closely monitor the pump's function and can make adjustments as needed to ensure optimal performance.

Medication-related issues, such as allergic reactions or incorrect dosages, can also arise. It is crucial for patients to discuss any allergies or concerns they may have with their healthcare provider, who will carefully select and adjust the appropriate medication to minimize potential risks.

Intrathecal Pump Removal Process and Considerations

There may be circumstances where the removal of an intrathecal pump becomes necessary. This could be due to infection, pump malfunction, or if the patient is no longer receiving adequate pain relief and alternative treatments are being considered. It is also considered when the patient's overall health has improved to the extent that continuous pain management is no longer required. Removing the intrathecal infusion pump is a surgical procedure carried out by a trained pain management provider.
