This procedure starts with a trial phase. Your doctor will place a catheter under your skin and into the intrathecal space around the spine. This will allow the release of medication into the fluid in that area. During the initial trial, the right dosage to give you pain relief is found. Once the proper level has been found, it is time to implant the infusion pump.
It may take several weeks to notice a significant reduction in your symptoms. The type or dose of medication you are getting can be adjusted at follow-up appointments.
After a pump is in place, it’s important to take care during sports or any other strenuous activity. X-rays do not interfere with this equipment, but an MRI might. You can also safely engage in activities that include commercial flight and scuba diving less than 78 feet.
The system’s medication is usually refilled every three to six months using a sterile needle. Pumps generally hold between 18 and 20 milliliters of medication and will signal if the amount in them goes below two milliliters.
