In order to define the impact of needle type on post-lumbar puncture headache (PLPH), we performed a prospective, randomized trial comparing the incidence of PLPH in patients undergoing lumbar punctures (LPs) with traumatic vs atraumatic 22-gauge needles. Fifty-eight patients underwent 85 LPs. The incidence of PLPH was 36% in the traumatic vs 3% in the atraumatic group (p = 0.002).
