Equation of Abe et al for Lumbar Puncture Needle Length

Abe et al reported an equation for estimating the lumbar puncture needle length. The authors are from University of Hawaii in Honolulu.

Patient selection: 25 days to 80 years

Parameters:

(1) weight in kilograms (range 3.0 to 127.3 kg)

(2) height in cm (range from 48 to 181.5 cm)

lumbar puncture in cm =

= (17 * (weight) / (height)) + 1

Performance:

• The correlation tip was 0.81.
