The spinal tap procedure is similar for children and adults. However, there are slight differences. For example, infants and small children lie on their sides and curl their bodies into the shape of a “C,” with their knees under their chin. A nurse or other aide may have to hold a child in the proper position. Some infants may be held upright during the procedure. Sick newborns are usually held upright because there is a risk of breathing problems if placed on the side with the body curled.

Teenagers are usually asked to lie down on their side with the knees drawn up to the chest. In some cases, teens may sit down and place their head on a pillow that is at waist level.

Spinal taps are very safe procedures that rarely result in complications. However, they can be frightening to a child. It is not unusual for children to cry during this procedure, and some children may need to be held still by a nurse or even sedated. Prior to the procedure, parents are encouraged to listen to their child’s concerns and to answer any questions honestly. Maintaining a loving and supportive presence can make the test easier for a child to endure.
