Heliox and Epinephrine Boost Response in Bronchiolitis

NASHVILLE, TENN. — Heliox may have a beneficial effect when used to deliver racemic epinephrine to young children with bronchiolitis, suggest the results of a randomized controlled trial. Investigators found that children treated with epinephrine and heliox improved significantly more than those treated with epinephrine and oxygen, Dr. In Kim reported in a poster presented at the annual congress of the Society of Critical Care Medicine. “The mixture of helium and oxygen delivers nebulization deeper and faster into the lungs and has been shown to ease the work of breathing in adults,” Dr. Kim, a pediatric emergency physician at Kosair Children's Hospital in Louisville, Ky., said in an interview. “This would also be very important for these little ones, in whom more work of breathing can lead to fatigue and even respiratory failure.”
