Final answer:
The Angoulvant 2017 paper concluded that hypertonic saline does not significantly reduce hospital stay for infants with bronchiolitis and should not be routinely used.
Step-by-step explanation:
The Angoulvant 2017 paper specifically investigated the efficacy of hypertonic saline in the treatment of bronchiolitis in infants. The study concluded that the use of hypertonic saline did not significantly decrease the length of stay in the hospital for infants with bronchiolitis. It suggested that hypertonic saline should not be routinely used as a treatment for this condition. The findings contributed to the ongoing research and discussions among healthcare professionals concerning the optimal management of bronchiolitis in young children.
