Washington ? Sometimes the numbing effect of TV can be helpful.

Especially if you’re a kid being stuck with a needle at the hospital.

Researchers confirmed the distracting power of television – something parents have long known – when they found that children watching cartoons suffered less pain from a hypodermic needle than kids not watching TV.

Especially disturbing to the author of the scientific study was that the cartoons were even more comforting than Mom.

While it’s good to have a powerful distraction for children getting painful medical procedures, it also is troubling “because we have demonstrated the excessive power of television,” said Carlo Bellieni, a father of three and a neonatologist and pediatrician at the University of Siena in Italy.

His research at a nearby hospital was reported this week in the British journal Archives of Disease in Childhood.

The study involved 69 children, ages 7 to 12, who were separated into three groups and then asked to rate their pain on a numerical scale when they were stuck with needle used to take a blood sample. The children’s mothers also rated the kids’ pain.

Those watching TV cartoons reported half the pain as those who were being soothed by Mom. When compared with children who just sat in a hospital room with mothers who didn’t try to soothe them, the TV watchers reported one-third the pain.

“The power of television is strong and it can be harmful for children if it is stronger than the force made by the mother to distract children,” Bellieni said. “I believe that this power must be controlled and reduced.”

In general, Mom’s soothing touch may be overrated, another expert said.

Other studies have found that parents’ attempts at comforting often backfire because it makes the children feel that “something must really be bad” if they need to be soothed, said Dr. Brenda McClain, director of pediatric pain management services at Yale University.

Bellieni, who has noticed the distracting effect of television on his own kids, theorizes that being absorbed in television releases pain-reducing hormones in children.
