Lumbar Puncture (Spinal Tap)

A Lumbar Puncture, also called a spinal tap, is a medical procedure where a small sample of cerebrospinal fluid (CSF) is taken from the lower part of the spine. This fluid surrounds your brain and spinal cord, and it can give doctors important information about your health.

 

Why is a Lumbar Puncture Done?

 

Doctors may recommend a lumbar puncture for several reasons, including:

 

• Diagnosing infections such as meningitis or encephalitis.
• Detecting neurological conditions like multiple sclerosis or Guillain-Barré syndrome.
• Checking for cancers that affect the brain or spinal cord.
• Measuring pressure in the spinal fluid.
• Delivering medications like chemotherapy or anesthesia directly into the spinal canal.

 

How the Procedure Works

 

• Preparation – You may be asked to lie on your side or sit up and lean forward to curve your lower back. This position helps the doctor access the spinal canal more easily.
• Cleaning & Numbing – The area in your lower back will be cleaned and numbed with local anesthesia so you stay comfortable during the procedure.
• Needle Insertion – A thin, hollow needle is gently inserted between two bones in your lower spine to reach the spinal fluid.

 

• Collecting the Sample – A small amount of CSF is collected in sterile tubes. If the purpose is to deliver medication, it is given through the same needle.
• Completion – Once the needle is removed, the site is covered with a bandage.

 

The whole process usually takes about 30–45 minutes, and most people can go home the same day.

 

What to Expect After the Test

 

It’s common to feel a mild headache or back discomfort after a lumbar puncture. To reduce this, you may be advised to:

 

• Rest for several hours.
• Drink plenty of fluids.
• Avoid heavy lifting for the next 24 hours.

 

If your headache worsens, or you notice fever, numbness, or any fluid leakage from the puncture site, contact your doctor immediately.

 

Is it Safe?

 

A lumbar puncture is generally safe when performed by an experienced medical professional. Some minor side effects like temporary headaches or soreness can occur. Serious complications are rare but can include infection, bleeding, or nerve injury. Your healthcare provider will discuss these risks before the procedure.
