A spinal tap (lumbar puncture) is a procedure to obtain CerebroSpinal Fluid (CSF), the fluid inside our skull that cushions our brain and likewise found in the spaces inside our vertebrae (back bone) that cushions our spinal cord.
This collection of CSF is for the examination, measurement or reduction of fluid pressure (in cases of increased pressure inside the skull or head).
Also, it can determine the presence or absence of blood in the fluid and to administer antibiotics into the spinal canal in certain cases of infection.
A spinal tap is carried out by inserting a needle into the lumbar subarachnoid space (back bone) to withdraw the fluid. A successful spinal tap requires that the patient be relaxed as this may alter the pressure reading results.
