Things That Can Go Wrong During Lumbar Puncture
Lumbar puncture (LP): Cerebrospinal fluid (CSF) bathes brain & spinal cord (cns). CSF may be abnormal in some diseases. In an lp, you are either on your side or sitting. Md feels lower back for interspace between 4th & 5th lumbar vertebrae, below end of cns. Lidocaine is injected. 3” hollow needle is inserted thru interspace & into sac holding CNS & csf. Md collects CSF (usually ~1 tsp) into 3-4 tubes. CSF sent to lab.See 1 more doctor answer
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?
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.
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.See 2 more doctor answers
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.
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.
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.See 1 more doctor answer
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.
Relax!: Simply said, your expectations and advice from others, regardless of how well they mean, can put a ton of stress and tension on you. A lumbar puncture is a fairly painless procedure. Staying as still as you can during and then laying down after are the two main things you should do. Otherwise, in experienced hands, the procedure is safe and fairly painless.See 1 more doctor answer
Lumbar puncture: The advice is mostly based on why the procedure was done. The key advice is to discuss with the physician why the procedure was done, were there any unusual results for findings and do you need any further treatment for the reason the puncture was done.
Low risk if experien: Lumbar punctures are extremely common procedures and when performed by an experienced individual have a very low risk of complications and the benefits generally far outweigh the risks. Nevertheless, there are serious potential complications.See 2 more doctor answers
Spinal tap: Needle inserted into lower back area into spinal canal to obtain spinal fluid for testing. Can evaluate possible infection, multiple sclerosis, various other diseases of brain and spinal cord.
Headache: It is common to experience a headache after an lp. Otherwise the effects are fairly minimal. The headache can be pretty bad, but they are very treatable.
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.See 1 more doctor answer
