Buzzy® and HSTT take the sting out of kids' injections
NCT ID NCT07509164
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether two simple, low-cost tools—Buzzy® (a vibrating device) and HSTT (a quick injection technique)—can reduce pain and fear in children aged 4 to 6 during intramuscular shots in the emergency department. 120 children participated, and researchers measured their pain and fear levels using special picture scales. The goal is to find easy ways to make injections less scary and painful for young kids.
