Post–lumbar puncture
headache is a frequent clinical problem.
Needle design is expected to
reduce post–puncture headache. In
this study, we compared two different
lumbar puncture needle designs
in diagnostic lumbar puncture and
analysed post–dural puncture
headache (PDPH) and social and
economical harm associated with
the diagnostic lumbar puncture procedure.
This prospective, controlled
study consisted of 80 consecutive
adult patients requiring elective
diagnostic lumbar puncture due to
various neurological symptoms.
Lumbar puncture was completed
either with Spinocan
®
22 G sharp
bevel needle or Whitacre
®
22G
pencil point needle. Patients were
asked about previous headache
symptoms and pain provoked by
puncture. One week after the lumbar
puncture all patients were interviewed
by telephone and occurrence
and type of headache, headache
intensity, medication and frequency
of impairment in activities of daily
living were asked. Need for epidural
blood patch was also recorded.
Thirty–three of 78 (42%) patients
experienced headache after diagnostic
lumbar puncture and in 26 (33%)
the headache could be classified as
PDPH. There were no statistically
significant differences between needle
types in the frequency of common
headache, PDPH, puncture
pain intensity, need for epidural
blood patch or sick leave. Also,
there were no other complications
except local back pain or headache.
In this study, the needle design did
not affect the frequency of PDPH.
Also, PDPH was common, occurring
in 33% cases and caused a considerable
amount of disturbance in
daily activities. Seeking help for
this condition was insufficient and
only part of these PDPH patients
were treated with epidural blood
patch.
