Where is the child's lumbar puncture site

Generally, the lumbar puncture of children should be carried out in the fourth and fifth lumbar space as much as possible, and the puncture needle selected is thinner than common needles. Especially for babies under six years old, it is necessary to choose a special lumbar puncture needle for children. Babies over six years old can choose adult lumbar puncture needles. Smaller lumbar puncture needles are not easy to cause cerebrospinal fluid leakage. In addition, the purpose of children's lumbar puncture is mainly to make a clear diagnosis of the disease or carry out corresponding treatment. If it is suspected that the child has an intracranial infection or other intracranial spinal cord lesions, a lumbar puncture should be performed in time. Because the baby’s spinal cord is relatively long and it is easy to cause spinal cord damage during puncture, the location of the puncture is lower than that of adults, which is not easy to cause spinal cord damage and is safer. Generally, adults’ choice is to perform puncture between the third and fourth lumbar vertebrae. For children, choose the following as far as possible for the puncture site of the lumbar vertebrae. Choose the fourth and fifth lumbar vertebrae for puncture.
