In 30 seconds
This randomized equivalence trial evaluated the effectiveness of Buzzy Ⓡ and Pikluc Ⓡ for pain relief during intramuscular injections in children aged 1-11 years. In children aged 1-3 years, all devices demonstrated equivalent pain relief, while in those aged 4-11 years, self-reported pain did not show equivalence. The study included 170 participants.
Key findings
- In children aged 1-3 years, all device comparisons showed equivalence in pain relief.
- For ages 4-11 years, self-reported pain did not show equivalence across devices.
- Observer-reported assessments suggested equivalence for Pikluc Ⓡ vs. Buzzy Ⓡ 30 seconds in older children.
Why it matters
Understanding effective non-pharmacological pain relief methods is crucial for improving the experience of pediatric patients during procedures. This study provides insights into the use of two devices that can help reduce pain during intramuscular injections.
