Eight-year-old Lily Merema was one of almost 500 children who took part in the REACT study, undergoing a tonsillectomy at PCH.

“Every time Lily became sick with any little germ, she got tonsillitis and she would end up quite unwell,” Mum Michelle said. “She was also a really noisy sleeper, so we decided to get her tonsils out.

“Lily was the perfect candidate to help and we were just keen to contribute to the research. The surgery made a world of difference – her quality of sleep is better, and it seems to have improved the way her body responds generally when she is unwell.”

Professor Graham Hall, Co-head of the Children’s Lung Health team at Telethon Kids, worked closely with Professor Regli-von Ungern-Sternberg on the study and said the findings had changed the way children getting tonsillectomies are managed.

“We demonstrated a simple, inexpensive solution which is easy to implement, but has great benefit,” he said. “It is possible that Ventolin could also be beneficial for children, and adults for that matter, having other types of surgery.

“There is the potential for more research in this area.”
