Insights
Pediatric pain and anxiety during blood draws can be reduced using Buzzy, ShotBlocker, and DistrACTION Cards. Buzzy and DistrACTION Cards were found to be equally effective, with ShotBlocker also showing benefits over no intervention.
Area of Science:
- Pediatric healthcare
- Pain management
- Child psychology
Background:
- Venous blood sampling is a common but potentially distressing procedure for children.
- Effective pain and anxiety management strategies are crucial for pediatric patient care.
- Non-pharmacological interventions are increasingly explored to minimize procedural discomfort.
Purpose of the Study:
- To compare the efficacy of three interventions—Buzzy, ShotBlocker, and DistrACTION Cards—in alleviating pain and anxiety during venous blood collection in children.
- To evaluate the effectiveness of these methods against a control group receiving standard care.
- To identify the most suitable intervention for reducing procedural distress in pediatric patients.
Main Methods:
- An experimental randomized controlled study was conducted with 242 children aged 9-12 years.
- Participants were allocated to one of four groups: Buzzy, ShotBlocker, DistrACTION Cards, or a control group.
- Data on pain and anxiety were collected using the Visual Analog Scale, Faces Pain Scale-Revised, and the State-Trait Anxiety Inventory for Children.
Main Results:
- All three intervention groups (Buzzy, ShotBlocker, DistrACTION Cards) demonstrated significantly lower pain scores compared to the control group.
- Children in the control group reported higher levels of anxiety during the procedure.
- The study indicated a reduction in both pain and anxiety across all tested intervention groups.
Conclusions:
- Buzzy, ShotBlocker, and DistrACTION Cards are effective non-pharmacological methods for reducing pain and anxiety in children undergoing blood collection.
- "Buzzy" and "DistrACTION Cards" were found to be equally effective and can be preferred.
- ShotBlocker is also a viable option for pain and anxiety management in this pediatric population.
Objectives:
The aim of this study was to compare the effectiveness of 3 methods (Buzzy, ShotBlocker, and DistrACTION Cards) in reducing pain and anxiety while taking venous blood samples in children.
Methods:
The study population consisted of children aged 9 to 12 years admitted to the Child Health and Diseases Department in a Faculty of Medicine in Turkey. The sample of the study consisted of 242 children (Buzzy = 60, ShotBlocker = 61, DistrACTION Cards = 60, control = 61) who met the patient selection criteria and agreed to participate in the study. The data were obtained using an Information Form, the State-Trait Anxiety Inventory for Children, visual analog scale, and the Faces Pain Scale-Revised.
Design:
This article is an experimental randomized controlled study.
Results:
During venous blood collection, the scores of visual analog scale were significantly lower in ShotBlocker, Buzzy, and DistrACTION Cards groups than the control group. It was also observed that the control group experienced more anxiety than the other groups.
Conclusions:
Methods such as Buzzy, ShotBlocker, and DistrACTION Cards can be used to reduce the anxiety and pain of children during painful procedures such as blood collection and vascular access. Among these methods, "Buzzy" and "DistrACTION Cards" can be preferred as it is equally effective, and then ShotBlocker can be preferred.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
