ABSTRACT
Objective To compare the effect of different body position and length of bed time after lumbar puncture on the postoperative headache.Methods Literatures were searched at home and abroad through the database,and provided comprehensive quantitative analysis to compare the effect of different body position and length of bed time after lumbar puncture on the postoperative headache by the Cochrane collaboration Meta-analysis.Results A total of 20 studies (3 514 patients) were included for Meta-analysis.Mter lumbar puncture for the low supine pillow and the pillow recumbent position,headache incidence rate had no significant difference between the two positions,combined odds ratio (OR) and 95％ confidence intervals were 0.87 (0.41-1.87)(P＞ 0.05);After lumbar puncture to stay in bed for a long time to rest (≥ 4 h) and short time in bed rest (＜1 h),headache incidence rate had no significant difference between the two different time,the combined odds ratio (OR) and 95％ confidence intervals were 0.77 (0.58-1.02)(P ＞ 0.05).Conclusions After lumbar puncture,the occurrence rate of headache is not increased after taking a low pillow lying position or a short time in bed rest (＜1 h).
