Information provided by:
A vibrating cold pack placed proximal to the site of immunization will decrease the pain of routine preschool immunizations when compared to standard care.

Condition Intervention
Pain Device: Buzzy

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Supportive Care
Official Title: Relieving Pediatric Immunization Pain Using A Reusable Personal Device

Further study details as provided by MMJ Labs LLC:

Primary Outcome Measures:
  • FLACC observational pain/distress scale [ Time Frame: 5 minutes ]
    Videotaped scores are generated from the 30 seconds before the immunization and during the first two and second two sets of shots. Scoring is complete when the final bandage is placed over the last immunization.

Secondary Outcome Measures:
  • Self report using Faces Pain Scale - Revised [ Time Frame: 1 minute after immunizations are complete ]
    After the first arm and second sets of two shots, children and parents are asked to indicate which face represents how much pain they (or the child) felt.

Estimated Enrollment: 60
Study Start Date: January 2009
Estimated Study Completion Date: July 2010
Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Standard Care
Immunizations given with standard care of no pain control
Experimental: Buzzy
Vibrating device with cold pack held to arm proximal to injections
Device: Buzzy
"Buzzy", the vibrating cold pack, is pressed by parent or nurse immediately prior to immunizations. The vibration is activated and the device remains in place throughout the procedure, moving locations to complete the 4 shots.
Other Name: Buzzy R

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 provides analgesia 6% of the time. An inexpensive, immediately acting form of needle pain control could reduce needle phobia or vaccine refusal in the long term if demonstrated to be effective for immunization pain.

This study will evaluate pain responses using video-coded FLACC scores for patients undergoing routine pre-school immunizations. Parent and patient pain assessments, as well as demographic information and pre-procedural anxiety coded from videos will be included.
