title: Reinsertion of the stylet does not affect incidence of Post Dural Puncture Headaches (PDPH) after spinal anesthesia.
abstract: OBJECTIVE
  This study was conducted to investigate the effects of reinsertion of the stylet after a spinal anesthesia procedure on the Post Dural Puncture Headache (PDPH) METHODS: We have enrolled into this study 630 patients who were undergoing elective operations with spinal anesthesia and randomized them to Group A (stylet replacement before needle removal) and Group B (needle removal without stylet replacement). These patients were observed for the duration of 24 hours in the hospital and they were checked for PDPH on the 3(rd) and the 7(th) day of the study.
  
  
  RESULTS
  Overall, the PDPH incidence was at 10.8% (68 patients). Thirty-three of these patients (10.5%) who were in Group A (stylet replacement before needle removal) and the other 35 patients (11.1%) who were in Group B (needle removal without stylet replacement) experienced PDPH. There was no significant difference between the two groups with respect to the PDPH.
  
  
  CONCLUSIONS
  In contrary to the diagnostic lumbar puncture, reinsertion of the stylet after spinal anesthesia with 25-gauge Quincke needles does not reduce the incidence of PDPH.
