Insights
Enteral hydration is safe for infants receiving high-flow oxygen therapy for bronchiolitis. This study found no pulmonary aspiration events in infants hydrated orally or via nasogastric tube while on high-flow oxygen.
Area of Science:
- Pediatric critical care
- Respiratory medicine
- Neonatology
Background:
- Nasal high-flow oxygen therapy is a common supportive treatment for infants with bronchiolitis.
- The safety of enteral hydration in infants receiving high-flow oxygen therapy is not well-established.
Purpose of the Study:
- To assess the safety of enteral hydration in infants with bronchiolitis receiving high-flow oxygen therapy.
- To evaluate adverse events associated with different hydration methods in this population.
Main Methods:
- A secondary analysis of a multi-center randomized controlled trial involving infants under 12 months with bronchiolitis and oxygen requirements.
- Infants were assigned to high-flow or standard oxygen therapy.
- Adverse events were assessed based on hydration methods: intravenous (IV), nasogastric tube (NGT) bolus/continuous, or oral.
Main Results:
- Of 505 infants on high-flow, 71.3% received only enteral fluids, and 18.4% received both IV and enteral fluids.
- Among enterally hydrated infants, methods included NGT bolus, continuous NGT, oral hydration, or combinations.
- No pulmonary aspiration events occurred in infants hydrated orally or via NGT (0%); one patient experienced pneumothorax (0.2%).
Conclusions:
- Enteral hydration is safe for the majority of infants with hypoxic respiratory failure due to bronchiolitis.
- Hydration via oral or nasogastric routes can be safely administered during high-flow oxygen therapy.
Aim:
Nasal high-flow oxygen therapy is increasingly used in infants for supportive respiratory therapy in bronchiolitis. It is unclear whether enteral hydration is safe in children receiving high-flow.
Methods:
We performed a planned secondary analysis of a multi-centre, randomised controlled trial of infants aged <12 months with bronchiolitis and an oxygen requirement. Children were assigned to treatment with either high-flow or standard-oxygen therapy with optional rescue high-flow. We assessed adverse events based on how children on high-flow were hydrated: intravenously (IV), via bolus or continuous nasogastric tube (NGT) or orally.
Results:
A total of 505 patients on high-flow via primary study assignment (n = 408), primary treatment (n = 10) or as rescue therapy (n = 87) were assessed. While on high flow, 15 of 505 (3.0%) received only IV fluids, 360 (71.3%) received only enteral fluids and 93 (18.4%) received both IV and enteral fluids. The route was unknown in 37 (7.3%). Of the 453 high-flow infants hydrated enterally patients could receive one or more methods of hydration; 80 (15.8%) received NGT bolus, 217 (43.0%) NGT continuous, 118 (23.4%) both bolus and continuous, 32 (6.3%) received only oral hydration and 171 (33.9%) a mix of NGT and oral hydration. None of the patients receiving oral or NGT hydration on high-flow sustained pulmonary aspiration (0%; 95% confidence interval N/A); one patient had a pneumothorax (0.2%; 95% confidence interval 0.0-0.7%).
Conclusions:
The vast majority of children with hypoxic respiratory failure in bronchiolitis can be safely hydrated enterally during the period when they receive high-flow.
