Examining Infectious Complications Following Lumbar Puncture in Children.

Little is known about infectious complications of lumbar puncture (LP) in children. We reviewed records of children with bacterial meningitis, intraspinal abscess, and vertebral osteomyelitis over a 3-year period to identify infections following LP. Four children with bacterial meningitis and 1 child with vertebral osteomyelitis were identified and their clinical presentations were described. These cases were scored by infectious disease experts, using a Likert scale, for the possibility of iatrogenic causation; these scores were variable, reflecting uncertainty. The bacterial meningitis cases had repeat LPs, and the latter cerebrospinal fluid analyses were diagnostic of bacterial meningitis; the interval between the initial "index" LP (I-LP) and symptom onset was 8 to 10 hours in most cases. Pediatricians should be aware of this possibility, and have a low threshold to repeat LP if there is a clinical change after the I-LP that could be consistent with meningitis.
