Premedication with lidocaine for an LP does not hinder the ease of obtaining CSF.The clinical relevance of a greater number of traumatic LPs in the lidocaine-treated group is questionable because this finding is negated when traumatic is defined as more than 10,000X10/6L CSF red blood cells.Based on these results,we advocate premedication with a local anesthetic when an LP is performed in the pediatric emergency department. |
