Effective Strategies

Use of atraumatic needle (Sprotte, Whitacre, and others)

Replacement of stylet prior to removal of needle

Performing LP in the lateral decubitus position

Insertion of needle with bevel oriented in a cephalad to caudad direction (when using standard needle)

Ineffective Strategies

Bed rest (up to 4 h) following LP

Supplemental fluids

Minimizing the volume of spinal fluid removed

Immediate mobilization following LP
