Why are epidural injections given in the lower lumbar region?

The goals of an epidural steroid injection are to: Control pain by reducing inflammation in and around the nerve roots. Improve mobility and function in the lower back and legs. Allow the patient to participate in and make progress with a comprehensive physical therapy and rehabilitation program.

Where is the epidural injection located?

An epidural injection is an injection of medication into the space around the spinal cord, also known as the epidural space, to provide temporary or prolonged relief from pain or inflammation. The epidural space is the outermost part of the spinal canal.

How does an epidural work?

How does an epidural work? An epidural anesthesia injection works by injecting an anesthetic into the epidural space around your spine so that it can stop pain signals from traveling from your spine to your brain. The epidural space is filled with fluid and surrounds your spinal cord.

What are the indications for epidural?

What are the indications for epidural steroid injections (ESIs)?

• Lumbosacral disk herniation.
• Spinal stenosis with radicular pain (central canal stenosis, foraminal and lateral recess stenosis)
• Compression fracture of the lumbar spine with radicular pain.
• Facet or nerve root cyst with radicular pain.
• Postherpetic neuralgia.

Why is access to the epidural space used in clinical practice?

The epidural space contains fat, veins, arteries, spinal nerve roots and lymphatics. The fat in the epidural space helps absorb shock, which protects the other contents in the area, as well as the dura. Arteries enter through the many passageways that are present in the epidural space.

Where in the vertebral column is an epidural generally done?

An epidural injection may be administered at any point of the spine, but most commonly the lumbar spine, below the end of the spinal cord. The specific administration site determines the specific nerves affected, and thus the area of the body from which pain will be blocked.

How fast does epidural injection work?

Usually, the immediate effect is from the local anesthetic injected. This wears off in a few hours. The steroid starts working in about 2-7 days and its effect can last for several days to a reasonably long time.

When is epidural administered?

Typically, you can receive an epidural as early as when you are 4 to 5 centimeters dilated and in active labor. Normally, it takes about 15 minutes to place the epidural catheter and for the pain to start subsiding and another 20 minutes to go into full effect.

How does an epidural work physiology?

The steroids in epidural injections have anti-inflammatory effects that suppress pain signals from inflamed spinal nerves and improve function in the lower back and/or legs. The medicated solution is injected directly into the epidural space.

How do you administer an epidural steroid injection?

What happens during treatment?

1. Step 1: prepare the patient. The patient lies on an x-ray table.
2. Step 2: insert the needle. With the aid of an x-ray fluoroscope, the doctor directs a hollow needle through the skin and between the bony vertebrae into the epidural space.
3. Step 3: inject the medication.

What are the purposes of using an epidural anesthesia analgesia?

Epidural analgesia is often used to supplement general anesthesia (GA) for surgical procedures in patients of all ages with moderate-to severe comorbid disease; provide analgesia in the intraoperative, postoperative, peripartum, and end-of-life settings; and can be used as the primary anesthetic for surgeries from the …

Where does the epidural space extend to and from?

The epidural space extends from the base of the skull to the end of dural sac at S2. It is a cylindrical structure enveloping the dura. The epidural space exists between the dura and ligamentum flavum. The actual size of epidural space varies greatly.

What is an epidural steroid injection for back pain?

Epidural injections for back pain An epidural steroid injection (ESI) is the delivery of powerful anti-inflammatory medicine directly into the space outside of the sac of fluid around your spinal cord. This area is called the epidural space. ESI is not the same as epidural anesthesia given just before childbirth or certain types of surgery.

When does a thoracic epidural injection make sense for You?

These include pain medicine and physical therapy. If these treatments don’t work, a thoracic epidural injection might make sense for you. It may be best if you have had moderate to severe pain for at least three months. A thoracic epidural injection may provide pain relief for several different types of back problems, like:

What are epidural and spinal blocks?

Epidural and spinal blocks are types of anesthesia in which a local anesthetic is injected near the spinal cord and nerve roots. It blocks pain from an entire region of the body, such as the belly, the hips, the legs, or the pelvis. Epidural and spinal anesthesia are used mainly for surgery of the lower belly and the legs.

What are the side effects of epidural injections?

These effects could indicate nerve damage and should be assessed by your doctor. Some patients experience an initial increase in pain in the affected area after having an epidural injection. This pain, which can last for several days, usually occurs when the local anesthesia wears off and the steroids have not started to take effect yet.
