Atlanta (CNN)Six-year-old Nhaijah Russell swallowed three or four squirts of seemingly innocuous liquid hand sanitizer at school. It tasted good, she said, like strawberry.

It also contained enough alcohol to make her dangerously drunk. She arrived at the emergency room slurring her words and unable to walk.

Since 2010, poison control center hotlines across the United States have seen a nearly 400% increase in calls related to children younger than 12 ingesting hand sanitizer, according to new analysis by the Georgia Poison Center.

"Kids are getting into these products more frequently, and unfortunately, there's a percentage of them going to the emergency room," said Dr. Gaylord Lopez, the center's director.

The amount of alcohol in hand sanitizer ranges from 45% to 95%. Ingesting even small amounts -- as little as two or three squirts in some cases -- can cause alcohol poisoning. By comparison, wine and beer contain about 12% and 5% alcohol, Lopez said.

Nhaijah's blood-alcohol level was .179, twice what's considered legally drunk in an adult, according to Dr. Chris Ritchey, who treated her in the emergency room at Gwinnett Medical Center near Atlanta. Doctors had to watch Nhaijah overnight at a nearby children's hospital for signs of brain trauma, since the alcohol had caused her to fall and hit her head, he said.

"That was very scary," Nhaijah's mother, Ortoria Scott, said. "It could have been very lethal for my child."

Alcohol poisoning can cause confusion, vomiting and drowsiness. In severe cases, a child can stop breathing.

Lopez said 3,266 hand sanitizer cases related to young children were reported to poison control centers in 2010. In 2014, the number increased to 16,117 cases.

Last week, Lopez sent a letter to Georgia's school systems warning about children drinking hand sanitizer. He explained that some children do it intentionally in order to get drunk, while others do it on a dare from friends. Still others, he said, drink sanitizer because it looks tasty.

"A kid is not thinking this is bad for them," Lopez said. "A lot of the more attractive (hand sanitizers) are the ones that are scented. There are strawberry, grape, orange-flavored hand sanitizers that are very appealing to kids."

Lopez recommends parents and teachers store hand sanitizer out of reach of children and monitor its use. He said non-alcohol based products or sanitizing wipes can also be used.
