On-going pain can destroy your quality of life. Limitations imposed by living with chronic pain may mean that activities such as work and hobbies, even little things that once brought satisfaction, pleasure and self-esteem, may only be memories.

Regaining quality of life is one of the goals of physicians who attempt to treat chronic pain. Pain signals go from the site of injury, through the spinal cord, to the brain where the signal is encoded as “pain.” Then the brain sends the interpreted signal back through the spinal cord to the site of injury. When that signal is blocked or scrambled, the message is not received as “pain” at the injury site.

Getting Your Life Back

Oral opiate medications as a treatment work for some people by altering the message sent to and from the brain. For others, doses enough to relieve pain may result in confusion, grogginess, over-sedation and other side effects. When attempts to increase quality of life and to manage pain with medications are unsatisfactory, your physician may recommend intrathecal pain therapy. This may be effective for pain that is caused by certain conditions, including failed back syndrome, arachnoiditis, osteoporosis and cancer.

How does Intrathecal Pain Therapy Work?

Intrathecal pain therapy works by delivering small doses of analgesic directly to the pain receptors in the spinal cord, blocking the message to the brain. Because the doses are small and applied directly at the site of pain receptors, the entire body is not flooded with medications, and therefore negative side effects such as grogginess, confusion and over-sedation are usually avoided. A surgically implanted pump delivers medication in small, regular doses. The medication goes through a catheter to the intrathecal space around the spinal cord where it most effectively blocks pain signals. Exact dosages and frequency of delivery are determined by the physician.

Once you and your doctor have decided that this is an option for long-term treatment, a trial will be arranged. A temporary catheter will be placed near your spinal cord and attached to an external pump. The trial usually lasts about 3 days and gives you a good idea of the degree of pain the pump will relieve. A successful trial will reduce your pain by at least 50%. During the trial, you should notice an improvement in your ability to perform daily activities.

What are the Risks Involved?

The potential risks of surgery to implant an intrathecal pump include any complication that can also occur with other types of surgery and anesthesia. These include:

  • Bleeding
  • Headache
  • Spinal cord injury
  • Hardware difficulties
  • Infection
  • Allergic reaction
  • Failure to relieve pain
  • Paralysis

There are some risks that are unique to the implantation of the infusion surgery and anesthesia. They include:

  • Infection
  • Accumulation of fluid in the pump pocket site
  • CSF leakage
  • Bleeding
  • Spinal headaches

The catheter could leak, become kinked, disconnected, or dislodged, thereby requiring additional corrective surgery.
A device component could fail, making it necessary to replace it. You could experience side effect or overdose symptoms of the drug being infused through the pump.

It is important that you discuss with your doctor the potential risks, complications and benefits regarding this therapy prior to giving your informed consent for treatment.


There will be some discomfort at the incision sites. Your doctor may prescribe something to help relieve post-surgery pain and an antibiotic to prevent infection. Infection is rare, but you do need to be aware of the signs of infection.

Signs of Infection:

  • Fever
  • Increased pain at the incision site.
  • Drainage that is pus-like in nature
  • Redness and swelling at the incision
  • Heat at the incision
  • Unpleasant odor at the incision

Other symptoms to report immediately

If you experience clear, watery fluid draining from your wound, or develop a headache when you are upright, you may have a spinal fluid leak. You should notify your doctor’s nurse or the doctor on call right away. You will want to limit your activity for 6 to 8 weeks in order to prevent the catheter from moving before healing is complete. After the incision has healed, the pump site will require no special care. Oral medications will be reduced as the amount of medication released by the pump is increased. It will take several weeks to reach the optimal dosage.

Maintaining Your Pump

You will schedule regular appointments with your doctor for pump refills. At each visit your pump will be checked to be sure it is working properly. Work with your doctor to find the effective medication dosage for you. Call your doctor’s nurse and report any unusual reactions to the medication. Call your doctor’s nurse immediately if you hear beeping sounds from the pump. It will beep to signal that attention is needed: a refill is due, the battery needs to be changed, or there is a problem with the pump delivering medication. Do not participate in activities that could result in a blow to the pump site.

Carry your pump identification card with you at all times. Consult with your doctor before scheduling any diagnostic tests such as MRI or other diagnostic imaging, or before engaging in treatments that could involve changes in atmospheric pressure (long flights, unpressurized flights, or hyperbaric chamber) or extreme changes in temperature (sauna or hot tub). Extreme temperature or pressure changes may result in the pump releasing too much medication or not enough. You can expect the battery to last 3 to 5 years, depending upon the amount of medication the pump delivers. At the end of battery life, the pump will need to be replaced.
