Intrathecal pump

Intrathecal pump is a medical device used to deliver medications directly into the space (intrathecal space) around the spinal cord. This method of drug delivery is often used for pain management and spasticity control.

Overview

An intrathecal pump is a small, round metal device that is surgically implanted beneath the skin of the abdomen. It is connected to a catheter that delivers medication from the pump to the intrathecal space around the spinal cord. The pump is programmable, allowing healthcare providers to adjust the amount and frequency of medication delivery.

Uses

Intrathecal pumps are used to manage severe chronic pain and spasticity that cannot be controlled by other treatments. Conditions that may benefit from intrathecal pump therapy include cancer pain, chronic pain syndrome, multiple sclerosis, cerebral palsy, and spinal cord injury.

Procedure

The procedure to implant an intrathecal pump involves a surgical procedure performed under general anesthesia. The pump is usually placed in the abdomen, and the catheter is threaded into the intrathecal space around the spinal cord. The pump is then filled with medication and programmed to deliver a specific dose at regular intervals.

Risks and Complications

As with any surgical procedure, there are risks associated with the implantation of an intrathecal pump. These may include infection, bleeding, and damage to the spinal cord. There is also a risk of complications related to the pump itself, such as mechanical failure or problems with the catheter.

Aftercare

After the procedure, patients will need regular follow-up appointments to monitor the function of the pump and adjust the medication dosage as needed. The pump will also need to be refilled with medication periodically.
