Incidence and effect of traumatic lumbar puncture in the neonate

The incidence of non-traumatic, traumatic and unsuccessful lumbar punctures in 181 neonates was similar whether a needle with a stylet, a butterfly needle without stylet, or a standard venipuncture needle without stylet was used. Comparison of 20 lumbar puncture pairs in 17 patients showed that traumatic lumbar puncture does not result in a cerebrospinal fluid pleocytosis between two and 13 days after initial traumatic lumbar puncture.
