Health: Will children become stupid when they have cerebrospinal fluid examination?

Many parents don't understand this kind of examination, and think that lumbar puncture and cerebrospinal fluid pumping will make their children stupid or cause paralysis. In fact, this view is wrong Lumbar puncture can not damage the spinal cord, let alone the brain. Because the site of clinical lumbar puncture is still far from the end of spinal cord. The brain and spinal cord are protected by three membranes: skull and pia mater. Under normal circumstances, cerebrospinal fluid (CSF) is a clear, colorless and transparent liquid, containing a small number of lymphocytes, no more than 5 per cubic millimeter, with little protein content, and other components are similar to plasma. Cerebrospinal fluid is constantly produced, and after a certain cycle, it continuously flows back to the heart through the venous system, so it goes on and on. The total cerebrospinal fluid in children is about 100~ 150 ml, and the normal lying pressure is not higher than 200 mm Hg. The neonatal cerebrospinal fluid is only 5 ml, and the lying pressure is 30~80 mm Hg. The human body has considerable ability to regulate the volume of cerebrospinal fluid. Adults can produce 20 ml of cerebrospinal fluid per hour, and if the cerebrospinal fluid is freely lost, it can produce 450 ml per day. It will decrease again after increased intracranial pressure, so the release of a small amount of cerebrospinal fluid after lumbar puncture will not affect the human body.

When children suffer from encephalitis, meningitis, cerebral hemorrhage and other diseases, cerebrospinal fluid will change greatly. As for some children with encephalitis, meningitis and other diseases, paralysis, mental retardation, paralysis, blindness, deafness and other phenomena occur after lumbar puncture, which is by no means caused by lumbar puncture, but the sequelae caused by the untimely or incomplete treatment of sick children, and has nothing to do with lumbar puncture at all. In addition, if the sick child is given spinal anesthesia, or a small amount of gas or imaging agent needs to be injected into the spinal cord for radiological examination, lumbar puncture is needed, but it will not cause any damage to the child. So don't worry too much about lumbar puncture.
