Abstract

PURPOSE: This study aimed to examine the factors influencing the appearance of headache and backache following diagnostic lumbar puncture in children, focusing on the need for strict bed rest after lumbar puncture.
METHODS
We studied 70 two-fifteen-year-old pediatric patients who underwent diagnostic lumbar puncture from July 2005 to July 2007 at Konkuk University Hospital. We divided them into two groups. Patients in the first group (n=24) were allowed free mobility and patients in the second group (n=46) were to have strict bed rest for four hours after puncture. Data were analyzed by age, sex, number of puncture attempts, cell counts and pressure in the cerebrospinal fluid (CSF), duration of bed rest, and occurrence of headache and backache.
RESULTS
The rate of complications was not significantly related to sex, age, presence of enterovirus, CSF pressure, or postural headache. The occurrence of headache was significantly correlated with white blood cell (WBC) count in CSF (P=0.043). Symptom frequency did not differ significantly between the groups. Backache was significantly related to the frequency of puncture attempts (P=0.046).
CONCLUSION
Strict bed rest following diagnostic lumbar puncture in children does not influence headaches and backaches. These are respectively related to the WBC count on the CSF profile and the frequency of attempts. Therefore, after lumbar puncture, absolute bed rest is not necessary and patients are more comfortable with free mobility.
