What should normal inter crainal pressure be during my last lumbar puncture my beginning pressure was 38 I was just wondering I also ha e iih?

What should normal inter crainal pressure be during my last lumbar puncture my beginning pressure was 38 I was just wondering I also ha e iih?

Positional: In the side-lying position intracranial pressure as measured during lumbar puncture should be between 100 and 150 cm of water pressure. If pressure is measured while sitting upright, pressure level in fluid column should extend to base of skull (foramen magnum) but numerically will exceed 150. The rest of your question is unclear. Are you asking about a post-spinal headache? ...Read more

I am getting a lumbar puncture in a month to test for ms. What should I expect during and the next few days after it?

Could get headache.: It's not unusual to get a post-LP headache, which can feel pretty strong and heavy. It's related to the volume of fluid removed, and is treatable. Not a guarantee, but that could happen. Most people tolerate them just fine. Good luck with everything. ...Read more

8 days ago I had a lumbar puncture and during the procedure I had a hot burning pain in the lateral thigh that radiated downward. Still on going?

Lumbar puncture pain: A pain (usually sharp) that radiates down the legs is suggestive of a nerve pain. I suggest you go back and discuss this issue with the health care provider who performed the lumbar puncture to make sure that these symptoms are not related to the procedure and that they need to be addressed. ...Read more

What number of drops of cerebrospinal fluid is collected during lumbar puncture?

What number of drops of cerebrospinal fluid is collected during lumbar puncture?

Not Drops: When collecting fluid during a lumbar puncture, we don't exactly count drops of fluid. Rather, we count CCs (cubic centimenters). Typically there are 4 tubes. We collect only 1-2 cc in the first and 2-6 in the rest. The amount collected depends on the purpose of the lumbar puncture. Decreasing fluid pressure, having enough fluid for many lab tests are 2 reasons to draw off larger amounts. ...Read more

Is it normal during a lumbar puncture to feel a zap or jolt down one leg or on one side as they are moving the needle inside?

Is it normal during a lumbar puncture to feel a zap or jolt down one leg or on one side as they are moving the needle inside?

"Normal"?: Having an LP isn't "normal;" it's done to rule in or out an ABnormality. Do the symptoms you report occasionally happen during an LP? Yes. The needle may brush past and stimulate a nerve root. You feel the sensation in the body part from which the nerve root transmits sensory input to the brain. I suppose rarely the needle injures the root but I've never had that happen. ...Read more

How is lumbar puncture performed?

Carefully :): Lp is typically performed in the office. You will lie on your side curled up into a tight ball. After sterilizing the area, local anesthetic is injected into the skin at the small of the back, and then a spinal needle is advanced between the vertebrae into the spinal canal. Once in the canal, the fluid pressure is measured and fluid is removed for analysis. Total time is typically 20 mins. ...Read more

How risky is the lumbar puncture?

LP: Lumbar puncture these days is done for diagnostic as well as anesthetic purposes. The needles used now are pencil point and the anesthetic agents injected are preservative free. So in experienced hands, there is no danger. However, if done above the level of L2, it has a potential of damaging the spinal cord. ...Read more

What does a lumbar puncture actually help to prove?

Spinal fluid answers: The question: does the patient have intracranial bleeding? (presence red cells or xanthochromia) or infection present? (presence of white cells, bacteria, viral culture/antigens) or multiple sclerosis (presence of abnormal proteins). Also a l.P. (lumbar puncture) may show a high opening pressure which is a sign of pseudo-tumor (cause of chronic headaches). L.P. 's are safer now done under xray. ...Read more
