What is a lumbar puncture (spinal tap)?

A spinal tap, also known as a lumbar puncture, is a medical procedure where a needle is used to access the space around the spinal cord in the lower back to collect cerebrospinal fluid (CSF) for testing, or to inject medication.

Before a lumbar puncture(spinal tap)

1.
If there is a risk of bleeding due to decreased platelet count, a platelet transfusion is performed.
2.
Visit the restroom beforehand.

During a lumbar puncture(spinal tap)

1.
You’ll be asked to lie on your side with your knees pulled up to your chest, which helps open up the space between your vertebrae.
2.
The area will be numbed with a local anesthetic to minimize discomfort.
3.
If there's any sign of bleeding where the needle was inserted, the procedure might be rescheduled for a few days later.

After a lumbar puncture(spinal tap)

1.
Rest flat on your back for about 4 hours to help prevent headaches and dizziness. Avoid using a pillow.
2.
Drink plenty of fluids to stay hydrated.
3.
If you notice any changes in blood pressure, body temperature, or sensations in your limbs, inform the medical staff right away.
4.
Keep the puncture site dry for 24 hours to lower the risk of infection.
5.
You can remove the bandage after 24 hours and there's no need for further disinfection. Watch the area for signs of infection or bleeding and if you notice anything unusual, contact your doctor immediately.
6.
Potential issues following a spinal tap can include nausea, vomiting, headache, dizziness, pain where the needle was inserted, numbness or other sensory changes, bleeding, a hematoma (a collection of blood outside of blood vessels), or infection at the puncture site.
