Here are some good news for troubled parents whose little children have swallowed LEGO (or two). A new pediatric researcher's study concluded that the toy should reappear within a few days. They know this because their test items voluntarily absorb the LEGO's figure heads and watch how long it takes to get them.
Yes, this is an up-to-date scientific article published in the reputable Journal of pediatrics and children's health with the title "Everything is great: Do not forget LEGO." This is from the same group of pediatricians behind the popular blog "Do not forget the bubbles." "We finally answered the burning question: how long does it take for the absorbed LEGO to go?" Co-founder of DFTB and co-author of paper Tessa Davis has contacted Twitter, "It's dedication to pediatrics, but it's worthwhile developing science and pediatric emergency care."
It's a pity, but it really is an important issue. As Bruce J. Lee, a professor at the Johns Hopkins Bloomberg Public Health School Forbes, young children like to swallow things, especially coins. There are preliminary studies exploring the passage of coins through the digestive tract, namely 1971 paper, which finds that most coins pass harmlessly within three to six days.
But nobody looked closely at the second most commonly absorbed element: small toy particles. And the heads of LEGO figurines are especially tempting for the culinary dog.
How would you find even six adults (three men and three women) wishing to swallow portions of LEGO? Davis et al, recruit their subjects from the online community of children's hospitals. They looked at anyone who had previous gastrointestinal surgery, problems with swallowing objects, or "disgust from faecal matter".
Each subject held a "stool diary", recording the bowel movements before and after the absorption of the LEGO heads. They evaluated the frequency and freedom of their stools based on the results of the Research Team of Hardness and Transit Research Team (SHAT). (Who says the pediatricians have no sense of humor?) After swallowing the toy, they spent the next three days sifting through their own skirt to determine when LEGO's head appeared. The number of days that had to be passed and retrieved was recalculated as a result of the find and download result (FART).
A bad cat never drew LEGO's head at all.
Five of the six participants had FART scores ranging from 1.14 days to 3.04 days, averaging 1.71 days (about 41 hours). And one bad bastard never drew the head of LEGO at all. we I know now this subject is the co-author of the book and pediatrician consultant Damian Roland, who he told the CBC he kept searching for his own face for two weeks, hoping that the toy would return without result. Maybe a little rough in the diet will help?
As Lee points out, this is a small study focusing on adults rather than on young children. The SHAT and FART results may differ more widely in the general population. Neither was it a blind study because the authors thought they just wanted too many of the partners or colleagues of the survey participants to cross over on their behalf. Other particles of a small toy of different shapes may take a shorter or longer time to pass through the body.
"One gambling site is quickly passing through elderly people without complications," the authors conclude, adding an important warning: "parents should be advised not to look for the object in the stool because it's hard to find." But also do not swallow these LEGO figurines heads in the first place, m? Kay?
