Lumbar puncture. Lumbar puncture (LP), also known as a spinal tap, is a medical procedure in which a needle is inserted into the spinal canal, most commonly to collect cerebrospinal fluid (CSF) for diagnostic testing. The main reason for a lumbar puncture is to help diagnose diseases of the central nervous system, including the brain and spine.
If people have a headache after a spinal tap, they are given pain relievers (analgesics). Lying flat as much as possible helps minimize pain. They are given fluids and caffeine, which increases the production of cerebrospinal fluid. Fluids are given by mouth or, if people are very dehydrated, intravenously.
