We investigated the impact of needle type on post lumbar puncture headache (PLPH) in hematologic patients undergoing LP. We prospectively compared traumatic (TN) vs. atraumatic 22G needles. Twenty-seven patients underwent 48 LPs, 22 with chemotherapy injection. PLPH occurred almost exclusively with TN (4% vs. 30% p=0.02), irrespective of chemotherapy injection.

Key words: lumbar puncture, intrathecal chemotherapy, post lumbar puncture headache, traumatic needle, atraumatic needle.
