To investigate the effect of Buzzy^® and ShotBlocker^® on reducing pain induced by intramuscular penicillin injections in children.

This was a randomized controlled study. A total of 150 Turkish children aged 7~12 years who presented to our pediatric emergency clinic and met the inclusion criteria were recruited. The children were randomly assigned to each group (control=50, Buzzy^®=50, ShotBlocker^®=50). Data were collected using an information form, the State-Trait Anxiety Inventory for Children, Visual Analog Scale, and Faces Pain Scale-Revised.

The children in the control group had significantly higher pain scores during the penicillin injection than the children in the ShotBlocker^® and Buzzy^® groups. The children in the Buzzy^® group had significantly less pain than the children in both the ShotBlocker^® and control groups (p<.001).

Buzzy^® was more effective compared with ShotBlocker^® in this study.
