A spinal tap, or lumbar puncture, is a neurological procedure to collect cerebrospinal fluid (CSF). Since CSF fluid is taken from the lower spine (lumbar), the medical term is lumbar puncture. This fluid acts a protective covering for the brain and spinal cord. It’s maintained at a certain pressure, acting as a buffer for the brain and spine.

Why Spinal Tap is Performed
Your doctor may recommend a spinal tap to evaluate a range of neurological problems, including:
- Brain bleeding caused by traumatic brain injury or bleeding aneurysm
- Infections in the brain or spine
- Rise in intracranial pressure, which can be caused by increased CSF pressure
In some instances, your doctor may prescribe a spinal tap so that medication can be injected directly into your spine.
What to Expect at Dignity Health
Our neurologists, physician assistants, anesthesiologists, and specialized nurses perform spinal tap procedures in our hospitals and specialty centers. The procedure usually takes about 45 minutes. After your doctor has positioned you on a table, he or she cleans the puncture area with antiseptic liquid. An injection of numbing medication may be given. Your doctor inserts a spinal needle, records the CSF pressure, and withdraws a sample of fluid. He or she may inject any necessary medications and then bandage the area.
Spinal Tap Recovery
Your doctor monitors your status for several minutes for possible bleeding around the spinal cord. You’ll lie flat on your back to put pressure on the puncture site. This helps reduce the risk of bleeding or leaking CSF fluid.
A lumbar puncture headache is the most common side effect (likely caused by a change in intracranial pressure). Tell your doctor about any discomfort you experience. The results of your spinal tap are typically available in a few days. Your doctor creates a personalized treatment plan based on these results.
