Lumbar
puncture procedures are performed by the doctors and midlevel providers
at Western Neurological Associates, PC, (WNA) in Salt Lake City, Utah.
A
lumbar puncture, also called a spinal tap, is a medical procedure
to obtain a sample of cerebral
spinal fluid (CSF) for cellular analysis, chemical analysis, and bacteriologic
examination. During the spinal tap procedure, a measurement of cerebral
spinal fluid pressure is made.
A spinal tap procedure is performed using a sterile technique and local anesthetic. A special spinal needle is inserted in the lumbar region of the spine (lower back), hence the name "lumbar puncture." Generally, the patient lies on his or her side. The procedure is mildly painful but usually tolerated well. A few cc's of cerebral spinal fluid (CSF) are removed, and the cerebral spinal fluid is rapidly replaced by the brain. Following the procedure, it is best for the patient to lie quietly in bed. Consumption of moderate quantities of fluid is encouraged.
Occasionally, severe headaches will occur even with the best of precautions. Typically, the headaches are better in the recumbent, or lying position, and worse in the upright position. The best management of these headaches is to stay horizontal as long as necessary, keeping well hydrated. Caffeine may help. If headaches occur following the spinal tap, please call our office to speak with the doctor (or midlevel provider) who performed the procedure or the covering doctor. As with any medical procedure, complications of infection (including meningitis) or hemorrhagic bleeding complications may potentially occur but are very rare.
