Abstract
Lumbar puncture was performed in 195 children and the depth of needle was recorded.
Our results show that the depth of lumbar puncture necessary to obtain uncontaminated
cerebrospinal fluid correlates best with the child’s weight. The simple formula:
mean depth of insertion (cm) = 1.3 + 0.07 x body weight (kg), can be used to
estimate the depth of lumbar puncture of children older than 3 months. The depths of
lumbar puncture of children younger than 3 months are mostly 1.0–1.5 cm.
