Lumbar puncture in infants

Lumbar puncture is indicated in any infant with symptoms suggestive of meningitis (seizures, intractable vomiting and unexplained fever) and in the evaluation of neonatal intracranial bleeding. The infant must be held firmly in the lateral decubitus or sitting position. Under sterile conditions, a 22- to 25-gauge needle is inserted into the L3-4 interspace. The most important complication is unrecognized compromise of respiratory status.
