title: Comparison of prevalence of post-dural puncture headache between six hour- supine recumbence and early ambulation after lumbar puncture in thai patients: A randomized controlled study.
abstract: OBJECTIVE
  To compare the prevalence of Post Dural Puncture Headache (PDPH) between 6 hour- supine recumbence and early ambulation in Thai patients.
  
  
  METHODS
  The present study was a prospective controlled study and enrolled the patients who underwent Lumbar Puncture (LP) from Phramongkutklao Hospital, Thailand. The background characteristics were recorded Standard LP method was done. The patients were randomized to 6 hour-supine recumbence and < or = 1 hour- (early ambulation) groups. Prevalence and characteristics of PDPH were compared.
  
  
  RESULTS
  Of 65 patients, there were 33 patients (50.8%) in the 6 hour-recumbent group and 32 patients (49.2%) in the early ambulation group. The background characteristics and CerebroSpinal Fluid (CSF) findings were not different between the groups. Prevalence of PDPH was 16.9% (overall), 18.2% (6 hours) and 15.6% (early ambulation). There was no statistically significant difference in prevalence, pattern and severity of PDPH between the groups.
  
  
  CONCLUSIONS
  The prevalence and characteristics of PDPH were not different between the 6 hour- recumbence and early ambulation groups.
