Background & Objectives : It is widely believed that the post-lumbar puncture headache (PLPH) is related to CSF leakage through the dural hole made by needle tract. So it is accepted that PLPH is prevented by at least 4 hour bed rest after lumbar puncture (LP). If bed rest was unnecessary, the administrative and nursing advantages would be obvious, especially in neurologic units, where LP has been done frequently. Therefore, we evaluate the incidence of PLPH in the ambulant and bed-rest patients prospectively and compared the incidence difference between two groups.
Methods : Eighty-eight patients without preceding headache who were done lumbar puncture for diagnostic purpose were selected prospectively. We compared the incidence of PLPH between the ambulant (50 patients) and bed-rest group (38 patients) at 6 hours and 24 hours. We also evaluated the effect of the CSF profile (count of RBC and
WBC, protein level, and opening pressure) on PLPH.
Results : The PLPH was found in 11 cases (12 .5%) among bed-rest and ambulant groups. The frequency of each group was 8% (3/38) in bed-rest group and 16% (8/50) in ambulant group, but there is no significant difference between two groups (p-value =0.26). The frequency of PLPH is also not correlated to the CSF profiles; count of RBC
and WBC, protein level, and opening pressure.
Conclusions : There is no significant difference between the ambulant and bed-rest group in the frequency of the PLPH. We conclude that the bed rest after LP is unnecessary for the prevention of the PLPH.
