Feasibility and acceptability of Buzzy^® on procedural pain and anxiety in children undergoing needle-related procedures: A randomized pilot clinical trial

Background: Procedures involving needles in pediatric patients can lead to considerable distress or anxiety. Few studies have compared the effects of numbing cream and Buzzy^® in this population.

Objectives: This study aimed to evaluate the feasibility and applicability of Buzzy^® in pediatric settings and assess the effects of Buzzy^®, compared to Maxilene 4, on procedural pain and anxiety in children and adolescents undergoing repeated needle procedures. Methods: A randomized pilot clinical trial compared the Buzzy^® and Maxilene 4. Participants were between 4 and 18 years old and required a needle procedure in hemato-oncology, immunology, or rheumatology. Pain and anxiety among participants were measured using the FLACC and PBCL scales, respectively. Parental and healthcare provider satisfaction was assessed through questionnaires. Results: A total of 93 participants were randomized, with 47 assigned to Buzzy^® and 46 assigned to Maxilene 4. No significant differences were observed in procedural pain or anxiety levels. Both parents and nurses found Buzzy^® to be acceptable and feasible. Discussion: This study did not show that Buzzy^® is superior for reducing pain and anxiety in this population. Conclusion: Although no significant results were found regarding its use, Buzzy^® remains an intriguing alternative. A study with a larger sample size would be crucial.
