Cerebrospinal fluid is found within the tissue that surrounds the brain and spinal cord. A hollow needle is inserted between two vertebrae into the cerebrospinal fluid space just behind them. The cerebrospinal fluid is collected in a tube.
Beforehand
The examination and the sedation are explained prior to the actual procedure. The medical pedagogical care provider prepares your child and explains what will be done during the procedure.
The examination
Your child lies on their side with bent knees. A sample of the cerebrospinal fluid is removed from the back through a hollow needle and then examined in the laboratory.
Afterward
Your child must lie flat for two hours after the puncture, so without a pillow. A plaster has been applied to your child's back. If the puncture site is sensitive, your child is given paracetamol. If clear fluid seeps out of the puncture site or if your child has a fever, contact the department.
