It is possible to calm children without using drugs prior to surgery, according to a study by researchers at the University of Adelaide and Women's and Children's Hospital.
The study said that computer games and funny doctors could calm kids before they were due to be given general anesthesia. Relaxation techniques such as yoga and meditation could also help because parental stress is often passed onto kids.
The study assessed 1800 children across the world and found that video games, clown doctors and computer games helped calm kids, but music therapy did not help.
The study also said that parents must relax ahead of their kids' surgery.
