Spinal tap, or lumbar puncture, is used for spinal anesthesia or occasionally other intrathecal medication administration, but the most common reason for LP is diagnostic sampling of the cerebrospinal fluid. The brain and spinal cord are contained within the dura mater and bathed in fluid. That fluid is supposed to be sterile and contain a certain amount of sugar and proteins, and no blood or pus. If things show up that aren't supposed to be there, that's a definite uh-oh often with very serious implications. In emergency medicine, for instance, it isn't at all rare that a headache will turn out to be caused by meningitis or a subarachnoid hemorrhage that was only a possibility on clinical grounds but diagnosed on the result of the LP. It's still more diagnostically accurate for many conditions than even the best CT and MR imaging studies.
The procedure is pretty straightforward. A long needle goes between the bones in the mid-lumbar back and slips into the space. The sac and fluid are there for the sampling, but the tip end of the spinal cord actually is at the upper end of the lumbar spine, so there's no risk of hitting the cord.
A spinal tap is a procedure performed when a doctor needs to look at the cerebrospinal fluid (also known as spinal fluid). Spinal tap is also referred to as a lumbar puncture, or LP.
Some of the reasons your doctor may want to do a spinal tap include the following:
To look for infection
To check to see if there is bleeding around the brain (subarachnoid hemorrhage)
To look for causes of unexplained seizures
To look for causes of headaches
Cerebrospinal fluid is a liquid that bathes the brain and spinal cord. An adult has about 140 mL (just under 5 oz) of spinal fluid. Typically, an adult makes 30-100 mL of spinal fluid daily.
A spinal tap or lumbar puncture is when a needle is inserted into the space between the vertebra in the back and cerebrospinal fluid, the clear fluid that bathes the spinal cord and brain is sampled. This is often used as a way to detect an infection such as encephalitis or meningitis, both very deadly conditions.
It can be a complex procedure becuase everything done needs to be kept sterile to not introduce any bacteria into the cerebrospinal fluid in the body.
A spinal tap is when a needle is put in your back to extract CSF (cerebro-spinal fluid). It's done to diagnose different diseases, such as MS, or other neurological diseases.
there are several reasons for one but the most popular are, 1) to obtain spinal fluid for testing as in MS patients and other brain related illnesses and 2) for administering drugs as in a block for delivering mothers.
