The Effect of ShotBlocker and Finger Puppet on Pain and Fear During Blood Drawing in Children: A Randomized Controlled Trial
This randomized controlled trial involving 90 children found that the ShotBlocker device was significantly more effective than both finger puppets and no intervention in reducing pain and fear levels during blood draws.

Imagine a child's visit to the doctor for a blood draw as a tiny, terrifying storm. For many kids, the sight of a needle brings a wave of pain and fear that can feel like a thunderclap. This study, conducted by researchers in Turkey, set out to find the best "umbrella" to shield children from that storm. They tested two different ways to help: a high-tech gadget called a ShotBlocker and a classic, playful Finger Puppet.
Here is the story of what they found, broken down simply.
The Three Teams
The researchers gathered 90 children (ages 5 to 10) and split them into three teams, like three different lanes in a race:
- The ShotBlocker Team: These kids had a special plastic device placed on their skin right before the needle. Think of this device as a "noise-canceling headphone" for your skin. It has tiny bumps that press against the skin to create a buzzing, tingling sensation. This sensation is so strong that it "jams" the signal of the needle prick, much like how loud music can drown out a whisper.
- The Finger Puppet Team: These kids got a different kind of help. A researcher put a cute animal puppet on their finger and made animal noises, chatting with the child to distract them. This is like trying to look at a scary movie while someone tells you a funny joke; your brain gets busy with the joke and forgets to focus on the scary part.
- The Control Team: These kids got the blood draw with no special gadgets or puppets. They were the "baseline" group, representing what happens when you just do the procedure without any extra help.
The Race Results
After the blood draws, the researchers asked three people to rate how much pain and fear the child felt: the child themselves, their parent, and an independent observer (like a referee). They used two simple tools: a "Face Scale" for pain (where you pick a face from a smile to a frown) and a "Fear Scale" (from a calm face to a scared face).
The Winner: The ShotBlocker
The ShotBlocker team won the race by a landslide.
- Pain: They reported the least amount of pain. The "noise-canceling" effect of the device worked so well that the needle prick felt much less sharp.
- Fear: They were also the least scared. Because the pain was lower, the fear naturally dropped too.
- The Verdict: The ShotBlocker was significantly better than both the Finger Puppet and doing nothing at all.
The Runner-Up: The Finger Puppet
The Finger Puppet team did better than the Control team, but not as well as the ShotBlocker team.
- Pain & Fear: The puppets helped distract the children, making the experience less scary and painful than if they had done nothing. However, the distraction wasn't quite as powerful as the physical "jamming" of the pain signal provided by the ShotBlocker.
- The Verdict: Puppets are a good helper, but they aren't the strongest shield against the pain.
The Last Place: The Control Team
As expected, the kids with no intervention felt the most pain and fear.
Why Did This Happen?
The researchers explain the difference using a simple concept called the "Gate Control Theory."
- The ShotBlocker works like a bouncer at a club. It sends a strong, non-painful signal (the tingling bumps) to the brain, which tells the "pain gate" to close before the needle's pain signal can get through. It's a direct, physical fix.
- The Finger Puppet works like a magician. It tries to trick the brain into looking away. While this is clever and helps with fear, it doesn't physically stop the pain signal from entering the brain as effectively as the ShotBlocker does.
The Bottom Line
This study shows that while both a ShotBlocker and a Finger Puppet are better than doing nothing, the ShotBlocker is the champion for reducing pain and fear during blood draws.
- ShotBlocker: Best for stopping the pain directly (like a physical shield).
- Finger Puppet: Good for distracting the mind and lowering fear (like a mental break), but less effective at stopping the actual pain.
The researchers conclude that for the quickest and most direct relief from pain during these quick procedures, the physical device (ShotBlocker) is the most powerful tool. However, puppets still have a role to play in helping children feel less afraid. The best approach might be to choose the tool that fits the specific child and the specific situation.
