Intrathecal pain pump insertion is a procedure to help with pain management. A small pump will be inserted in your body. The pump will be able to deliver pain medication to the area around your spinal cord.
This pain management technique is often only used if noninvasive pain management has failed or has negative side effects.
An intrathecal pain pump can be used to manage long-term pain problems caused by: Failed back or neck surgeryCompression fracturesPhantom limb painCancerComplex regional pain syndrome
type I and type IIArachnoiditis—inflammation of a space around the spinal cord
Many people have a significant reduction in pain and are better able to function in daily life after having an intrathecal pain pump insertion.

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems like: BleedingInfectionSpinal headachesCatheter tube becomes blocked and stops workingSide effects from the pain medicationPump-related complicationsNerve injury
Factors that may increase the risk of complications include: Active infectionAllergy or intolerance to the pain medication or materials being usedBleeding disorders, concurrent anticoagulation therapyPsychological problems
Your doctor may do the following: Physical examBlood testsElectrocardiogram
Chest x-rayMRI scan of the spine
Before the surgery, you will undergo a trial to see if the pump will actually decrease your pain. Pain medication will be injected into the area around your spine one or more times. In some test trials, a catheter may be placed in the area around your spine. The catheter is then connected to an external pump. The proper placement of the catheter and ideal dose of medication for you will also be found in the trial period.

Leading up to your procedure: Do not eat anything after midnight the night before your surgery, unless directed otherwise by your doctor.Arrange to have someone drive you to and from the procedure.Arrange for help at home after your procedure.
Talk to your doctor about your medications. You may be asked to stop taking some medications up to 1 week before the procedure.
A small incision will be made in the middle of the back. The catheter is placed in a space near the spinal cord and secured with stitches. An x-ray machine will be used to make sure the catheter is in the right place. Once secured, the catheter is run from the spine to the abdomen where the pump is placed. The catheter is run under the skin.
After the abdomen is opened with a small incision, the pump is put in place below the waistline. The pump will sit in a pocket that is made between the skin and muscles. The catheter will be attached to the pump. After the pump is secured, stitches will be used to close the incision.
After the procedure, you will be taken to a recovery area. Your blood pressure, heart rate, and breathing will be monitored. The staff will watch for potential side effects, like: SedationSlow breathingConstipationItchingNausea and vomitingHeadacheAgitation
