BackgroundPain from needle-related procedures in children can alter pain perception, increase pain sensitivity, and generate inappropriate pain responses. Currently pain management includes the use of lidocaine-containing patches, which is complicated to manage in a busy medical setting such as a vaccination centre. We assessed the BuzzyⓇ device, which combines vibration and cold, to manage pain in children undergoing a needle-related procedure, compared to the standard lidocaine patch.DesignProspective, open-label, non-inferiority trial.SettingThe vaccination centres of three university hospitals in France.ParticipantsFrench speaking children aged 4-15 requiring a needle-related procedure (vaccination or venepuncture) were eligible. Principal exclusion criteria were allergy or sensitivity to the lidocaine patch.MethodsChildren were randomly allocated (1:1) to use either the BuzzyⓇ device or the lidocaine patch during the needle-related procedure. The lidocaine patch was applied to the puncture site for the hour prior to the intervention. The BuzzyⓇ device was applied to the puncture site for 30 s and then moved 5 cm along the limb during the procedure. The refrigerated wings were detached if they bothered the child. The child assessed their pain using the validated Revised Faces Pain Scale. The revised faces pain scale comprised six facial expressions from 0, normal "no pain" to 10, a screaming face "severe pain" (2 points/face). The primary endpoint was the average pain score recorded by the child. The study aimed to test the non-inferiority of BuzzyⓇ.ResultsOverall 219 participants were randomised. The primary outcome was assessed in 215 children: 108 in the BUZZY group (43% asked for the refrigerated wings were de to be detatched before the end of the procedure) and 107 in the PATCH group. The baseline characteristics were similar between the study groups with an average age of 9 (range: 4.08-15.81). The average needle-related pain was 2.04 in the BUZZY group and 1.42 in the PATCH group. The average difference between the children's assessments in the groups was 0.62, thus faling to demonstrate non-inferiority.ConclusionsOur study failed to show that the BuzzyⓇ device was not inferior to the lidocaine patch in managing pain in children undergoing needle-related procedures.
