M. Lenaerts et al., NO SIGNIFICANT EFFECT OF AN ATRAUMATIC NEEDLE ON INCIDENCE OF POSTLUMBAR PUNCTURE HEADACHE OR TRAUMATIC TAP, Cephalalgia, 13(4), 1993, pp. 296-297
We compared the incidence of post-lumbar puncture headache and of red
blood cells in the first CSF sample (traumatic tap) in 35 inpatients p
unctured with a standard 20 G Yale needle and in 26 patients punctured
with Sprotte's ''atraumatic'' needle. No significant difference was f
ound between the two groups in incidence of headache or in frequency o
f traumatic taps.
