Objective and subjective side effects of research lumbar punctures in children and adolescents.

Lumbar punctures are a common clinical procedure in pediatric populations, yet little systematic information about side effects or the child's perspective of the procedure is available. In a subset (n = 20) of a sample of children and adolescents with disruptive behavior disorders, we recorded children's ratings of research lumbar puncture in comparison to other hospital experiences of blood sampling, electroencephalography, and going to school. Lumbar puncture did not differ from the other procedures in terms of preference. (School attendance was the last choice of 50% of our patients.) Postlumbar puncture headache occurred in 13 of 60 (22%) patients (age 6.5-19.8 years). Adults may overestimate the relative noxiousness of lumbar punctures in children.
