Vibration and Cold Sensation Can Reduce Pain in Children during Venipuncture

Needle-related procedures, such as intravenous (IV) cannulation, are a major source of pain and distress for hospitalized children, often leading to long-term consequences like needle phobia, heightened pain sensitivity, and traumatic memories. Effective, rapid, and affordable methods are needed to manage this pain. The Buzzy device, a vibrating cold device based on the Gate Control Theory, combines cold and thermomechanical stimulation to block pain signals and increase pain thresholds. This study aimed to assess the effectiveness of the Buzzy device in reducing pain and anxiety levels in children undergoing peripheral IV cannulation. This prospective, randomized study compared the effectiveness of the Buzzy device (vibrating cold device, VCD) and topical lidocaine (TL) in reducing pain during IV cannulation in children aged 3-18 years. Pain levels were assessed using the FPS-R and FLACC scales, while caregiver and nurse satisfaction were evaluated through surveys. Exclusion criteria included critical illness, local infection, or conditions affecting sensation. This study included 120 children randomized into two groups: 60 received the VCD and 60 received TL. Both groups were comparable in demographics and prior IV experiences, though the VCD group had higher pre-procedure FPS-R scores (p<0.001). The VCD group showed significantly fewer venipuncture attempts, lower FLACC scores, and shorter procedure durations (p<0.001). Caregivers and nurses reported higher satisfaction with the VCD method regarding pain relief, comfort, and likelihood of reuse or recommendation (p<0.001). No side effects were observed in either group. This study demonstrated the effectiveness of the Buzzy device in reducing pain and anxiety during IV cannulation in children aged 3-18 years. Compared to topical lidocaine, the Buzzy device resulted in fewer venipuncture attempts, lower FLACC scores, and higher caregiver and nurse satisfaction. Its affordability, ease of use, and efficacy make it a
