What is intrathecal drug delivery?

Intrathecal drug delivery, also known as the "pain pump," uses a small pump to deliver pain medication directly to your spinal cord. The pump is surgically placed under the abdominal skin and delivers pain medication through a catheter to the area around your spinal cord.

Furthermore, what drugs are given Intrathecally?

Currently there are only three medications approved by the US Food and Drug Administration (FDA) for use via the intrathecal route, ie, morphine, ziconotide, and baclofen. Morphine targets opioid receptors within the dorsal horn.

Secondly, is Intrathecal the same as spinal? Anatomy and physiology. The spinal cord rests in a medium of cerebrospinal fluid (CSF) and is contained by a series of protective membranes, known as the meninges: the pia mater, arachnoid mater and dura mater. The intrathecal space lies between the arachnoid mater and pia mater and contains the CSF (Figure 1).

Also to know is, where is intrathecal injection given?

Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF) and is useful in spinal anesthesia, chemotherapy, or pain management applications.

Is intrathecal injection painful?

Because of the short half-life of cytotoxic agents (methotrexate and cytarabine), frequent intrathecal injections (lumbar punctures) are necessary, which are painful and inconvenient for the patient.

How long does an intrathecal last?

Onset and duration of action A 25-μg dose of fentanyl lasts 60 to 90 minutes. A 10-μg dose of sufentanil lasts about 2 hours. Synergy has been noted between 10 μg of intrathecal sufentanil¹⁸ or 25 μg of fentanyl¹⁹ and 2.5 mg of bupivacaine, with analgesia lasting about 3 hours (level I evidence).

What medication is used in pain pump?

An intrathecal pump or a "pain pump" is a device that delivers small quantities of pain medication such as morphine or baclofen, directly to the spinal fluid.

How long do pain pumps last?

Depending on how much medication the pump delivers, the battery will eventually need to be replaced every 5 to 7 years.

What are the side effects of intrathecal chemotherapy?

IT chemo may cause a headache, fever, nausea, or vomiting. It may also cause your eyes to be sensitive to light. Spinal fluid may leak from the LP site. Your nerves or spinal cord may be damaged during an LP.

Where is the intrathecal space located?

Also known as the subarachnoid space, the intrathecal space is the fluid-filled area located between the innermost layer of covering (the pia mater) of the spinal cord and the middle layer of covering (the arachnoid mater).

What chemotherapy can be given Intrathecally?

Intrathecal (IT) chemotherapy consisting of methotrexate, cytarabine, or the two in combination is frequently used for the prophylaxis and treatment of CNS metastasis.

What is spinal theca?

Anatomical terminology. The thecal sac or dural sac is the membranous sheath (theca) or tube of dura mater that surrounds the spinal cord and the cauda equina. The thecal sac contains the cerebrospinal fluid which provides nutrients and buoyancy to the spinal cord.

What is intrathecal pressure?

: introduced into or occurring in the space under the arachnoid membrane of the brain or spinal cord intrathecal drugs.

What drugs Cannot be given Intrathecally?

Drug-Induced Disorders of the Nervous System Other drugs that may be toxic when given intrathecally include baclofen, lidocaine, morphine, chymopapain, methotrexate, cytarabine, and radiologic contrast materials. Epidural injections are not associated with such reactions unless there is inadvertent dural penetration.

Why is intrathecal chemotherapy used?

Intrathecal (IT) chemotherapy is used to treat cancers that have entered into the CSF. When a cancer has gotten into the CSF, it may be called CNS (central nervous system) involvement. To determine if cancer cells are present in the CSF, a procedure called a lumbar puncture is done.

Why Dextrose is added to bupivacaine?

Dextrose is added to anesthetic solutions for subarachnoid administration to render the solution hyperbaric (heavier than cerebrospinal fluid [CSF]); the local anesthetic will exert its effect above or below the site of injection, depending upon the position of the patient during and immediately following the injection

What is intrathecal analgesia?

What is intrathecal analgesia (IA)? IA is a type of pain control. It is also called spinal anesthesia. Pain medicine is injected around your spinal cord to control pain from surgery or labor and delivery. IA can also be used to control long-term pain from illnesses, such as cancer.

What is intraperitoneal route?

Intraperitoneal injection or IP injection is the injection of a substance into the peritoneum (body cavity). It is more often applied to animals than to humans. Fluids are injected intraperitoneally in infants, also used for peritoneal dialysis.

What is the purpose of intradermal injection?

AN INTRADERMAL injection may be given for diagnostic purposes, such as allergy or tuberculosis testing. Medication injected into the dermis is absorbed slowly because of this skin layer's limited blood supply.

How do you give an intracardiac injection?

Intracardiac injection. The needle is inserted 1 cm to the left of the xiphoid process and aimed toward the left shoulder. The needle may also be inserted parasternally in the left fourth or fifth intercostal space (as denoted by the symbol “⊗ ”).

What is intradermal route?

Intradermal injection, often abbreviated ID, is a shallow or superficial injection of a substance into the dermis, which is located between the epidermis and the hypodermis. This route is relatively rare compared to injections into the subcutaneous tissue or muscle.

What is intraspinal injection?

Intrathecal or Intraspinal Drug Delivery (IDD) For this therapy, the doctor places a catheter beneath the skin and into the space along the spine (the intrathecal space) to release the medicine into the cerebrospinal fluid that bathes that area.
