Pumping cerebrospinal fluid in children has a very tiny effect on the child, because the cerebrospinal fluid is relatively large and in a constant formation, and when a small amount of cerebrospinal fluid is pumped to a child, new cerebrospinal fluid is formed very quickly, and the effect on the child is negligible. If the cerebrospinal fluid is drawn improperly or the condition is severe, adverse effects can occur: firstly, it can cause low cranial pressure syndrome in children, which can lead to headaches and other symptoms if the child receives too much cerebrospinal fluid from the cerebrospinal fluid or if the child is not given a decubitus position to lie down after the cerebrospinal fluid has been drawn. Secondly, it can lead to cerebral herniation. If the intracranial pressure in a child is very high, and there is no appropriate treatment to lower the cranial pressure, then pumping the cerebrospinal fluid can lead to cerebral herniation.
