Aim: To identify nurses' doubts and questions (about lumbar puncture, related nursing interventions and post-dural puncture headache - PDPH) and to find answers in the available literature.
Methods: 26 nurses were asked to identify open questions and a literature review was conducted searching on Medline, Cochrane database of Systematic Reviews and Cinahl.
Results: Atraumatic needles, small gauge, cranial bevel oriented insertion and stylet reinsertion are variables that reduce the risk of PDPH. Bed rest has no efficacy in reducing this complication. On the contrary, it may increase the risk of PDPH. There are not enough evidences about the efficacy of additional fluid intake after the procedure. It's not clear if the risk of PDPH could be affected by the position during lumbar puncture and the volume of cerebrospinal fluid withdrawn.
Conclusions: This literature review clarifies some aspects of lumbar puncture and PDPH: the use of traumatic or atraumatic needles, the bevel orientation and stylet reinsertion, bed rest. More research is needed to study the efficacy of other interventions, still uncertain (patient position during the procedure, volume of cerebrospinal fluid withdrawn, hydration and analgesic drugs' efficacy).
