Preparing for a Spinal Tap

By Whitney Pope, Director of Nursing

The phrase “lumbar puncture” can be a bit intimidating, so let’s walk through it together.  

A lumbar puncture, or spinal tap, is a procedure in which a needle is inserted between two lower back vertebrae to collect cerebrospinal fluid (CSF). This is done for diagnosis, research, or to deliver medication directly to the central nervous system. 

At IMSMP, our experienced doctors perform lumbar punctures regularly, and we make sure it’s a comfortable and reassuring experience. We also use an exceptionally thin needle to enhance comfort and reduce the risk of headaches. 

Before

To prepare for a lumbar puncture, let your provider know if you take:

  • Aspirin
  • NSAIDs like ibuprofen, Advil, and Aleve
  • Blood thinners, like Coumadin 

There are no dietary restrictions before a lumbar puncture, but you should wear loose, comfortable clothes and arrange for someone to drive you home. Lastly, let us know if you have any allergies

During

Here’s a run-down of the procedure itself: 

  1. A nurse and physician will explain the procedure and answer any questions you have. 
  2. We will help you move into a lying position on one side or a seated posture, leaning forward for support. 
  3. We’ll give you a local anesthetic to numb the area (you may feel a brief sting here). 
  4. After you’re numb, a thin needle is inserted into your lower back to collect CSF and/or administer medication. You may feel some pressure. 
  5. The needle is removed, and a bandage is placed over the site. 

The entire process, including preparation, takes about 45 minutes. 

After

After the procedure is complete, you will lie flat in the office for one hour to help prevent headaches. 

When you get home, rest lying down for the remainder of the day, only getting up for meals and the bathroom (but of course, don’t lie flat in the car for safety reasons!). Keep your bandage on for 24 hours. During those 24 hours, avoid strenuous activity, heavy lifting, and exercise, and keep the area dry. 

At IMSMP, our physicians are on call 24/7. If you’re one of our patients, a nurse will call you the next day to check in, but you should call us immediately if you experience a severe headache, fever, or anything else that concerns you.  

With the right care team by your side, lumbar punctures can be an important tool in your MS diagnostic toolbelt.
