Is lumbar puncture in children dangerous?

Everyone is not unfamiliar with venous blood drawing and intravenous injection, and it is acceptable. In fact, the same is true for lumbar puncture, just a needle. Lumbar puncture is to insert a very thin and long lumbar puncture needle through the skin and muscle into the lumbar intervertebral space, puncture the dura mater to the subarachnoid space, and take out a small amount of cerebrospinal fluid for biochemical and cytological examination.

Because the site of lumbar puncture is in the third and fourth lumbar intervertebral spaces of the spine, and in the process of human development, the length of the spinal cord and the spinal cord are not the same. At this segment, there is no spinal cord, so parents do not need to Fear of injury to the spinal cord during puncture.

There are also some parents who think that lumbar puncture is "brain and spinal cord pumping", which will make children stupid. This understanding is also wrong. A lumbar puncture is actually not the "cerebrospinal fluid" that people think, but "cerebrospinal fluid". Cerebrospinal fluid is just a colorless and transparent fluid that circulates on the surface of the brain and spinal cord. It is in a state of constant renewal, with 0.3 ~0.4ml of cerebrospinal fluid is produced. It can be seen that, according to its production rate, when the doctor draws out 3ml of cerebrospinal fluid during a lumbar puncture, they can be regenerated in about 10 minutes. Therefore, "pumping a little cerebrospinal fluid" will not give children. It will not cause harm to your health, nor will it damage the brain and cause sequelae.

Since lumbar puncture is not as scary as imagined, is lumbar puncture a necessary check? The answer is yes. First, let's look at the properties of cerebrospinal fluid. Cerebrospinal fluid is an extracellular fluid. The brain and spinal cord are soaked in cerebrospinal fluid. When the brain, spinal cord, cerebrospinal fluid, blood vessels and other tissues undergo pathological changes, the pressure and composition of cerebrospinal fluid can be changed. Therefore, in the diagnosis of some diseases in pediatrics, we often use lumbar puncture to collect a small amount of cerebrospinal fluid for testing to help diagnose, so that doctors can make targeted treatment plans as soon as possible. The seemingly terrifying but very necessary examination undoubtedly pushed the child to a very dangerous situation. Taking purulent meningitis as an example, lumbar puncture and cerebrospinal fluid examination can be used for early diagnosis and targeted medication. Early diagnosis and timely treatment are very critical to the prognosis. If the opportunity for diagnosis and treatment is missed, the consequences will be disastrous.

In addition, the success of lumbar puncture is also closely related to the degree of cooperation of the child and his family. In fact, during the lumbar puncture, the doctor will give the child local anesthesia. The pain that the child suffers is similar to the usual intramuscular injection. Therefore, for parents, first of all, they should calm down their emotions and reduce anxiety, so as not to cause harm to the child. Uncomfortable hints. Then encourage the child more, reassure the child, and let the child turn his attention to the things he likes. During lumbar puncture, the patient's body should be in a flexed position as much as possible, the knee joint should be as close to the chest as possible, and the space between the vertebrae should be fully exposed, so that the doctor can smoothly insert the needle. It is necessary to let the child avoid coughing and make changes in body position as much as possible to avoid discomfort caused by the lumbar puncture needle touching the paraspinal nerve. After the lumbar puncture, the child should generally lie down for about 6 hours. The purpose of lying down is to prevent Headache due to changes in intracranial pressure after lumbar puncture.

In a word, as long as the doctor reasonably grasps the indications, performs the operation in accordance with the normal operating specifications, and operates carefully and carefully, and the children and their families actively cooperate, lumbar puncture is a safe procedure without obvious side effects and sequelae. Accept it so that you don't miss the best opportunity for diagnosis and treatment.
