Before a lumbar puncture, a thorough examination is performed to look for these conditions. A lumbar puncture can be performed in a medical clinic or hospital. During the procedure, a patient either sits or lies on his or her side on a table or bed. Nervous patients may be given a mild sedative. A local pain killer may be given at the puncture site.
Some discomfort is felt only when the lumbar puncture needle is inserted.
A small sample of fluid is drawn and the pressure measured. The whole procedure should last only a few minutes. This is especially true for relaxed patients. After the procedure, it is important to drink fluids, and to stay quiet for a while. Lying down may help avoid a headache.
