Study summary

The hypothesis of this study is that distraction cards used by the caretaker along with a vibrating cold pack placed proximal to the site of immunization will decrease the pain of routine pediatric immunizations when compared to a placebo device or standard care.

Read the detailed description

Needle pain is the most common and the most feared source of childhood pain, resulting in needle phobia for 10$ of adults. Current standard of care for immunizations in the US is no pain relief. An inexpensive, immediately effective form of needle pain control could reduce needle phobia or vaccine refusal in the long term if demonstrated to be effective for immunization pain.

Distraction can decrease procedural distress in children by 50%. The effect of using a multi-modal pain and distraction relieving approach has not been rigorously studied.

Study arms

  • No intervention
    Standard Care

    Immunizations are given with standard care of no pain control

  • Active comparator
    Experimental

    Vibrating device with cold pack held to arm proximal to injections within the same dermatome; caretakers offered and instructed in use of distraction cards.

    Device: Device: Buzzy

  • Sham comparator
    Sham Device

    The device without batteries or cold pack held to arm proximal to injections. No formal distraction.

    Device: Buzzy: sham device

Interventions

  • DeviceDevice: Buzzy

    "Buzzy", the vibrating cold pack, is held in place with a velcro strap or pressed by caretaker or nurse immediately prior and during immunizations. The vibration is activated and the device remains in place during the shot, moving locations if multiple shots are given. Distraction cards with pictures on one side and questions on the other are shown to the child while the caretaker asks the finding and seeking questions on the back.

    Also known as: Buzzy(R), Flippits(TM)

  • DeviceBuzzy: sham device

    The identical device without batteries or a cold pack is held in place proximal to the site with a velcro strap or pressed by parent or nurse immediately prior to immunizations. The device remains in place throughout the procedure, moving locations to complete multiple shots.

    Also known as: Buzzy

What researchers measure

Primary outcomes

  1. Pain of immunization

    Infants' and toddlers' pain is assessed by coding videotapes using the FLACC (face, legs, activity, crying and consolability) scale. Patients age 4 and older rate pain using self-report via the Faces Pain Scale Revised.

    Time frame: 5 minutes during or immediately after immunizations

Secondary outcomes

  1. Pain from immunization using observational measures

    Caretakers and nurses administering the shots rate pain using a 10cm Visual analog scale from "no pain" to "most pain possible"; duration of infant cry is also assessed following the procedure using coded videotape recordings.

    Time frame: 5 minutes immediately following immunization

  2. Treatment satisfaction

    10 item scale ranging from "strongly agree" to "strongly disagree" with ten parameters of satisfaction with the methods and concepts of immunization.

    Time frame: 5 minutes after immunizations

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 22, 2011, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
