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.

Acute Respiratory Failure-V

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Acute Respiratory Failure-IV01:23

Acute Respiratory Failure-IV

Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
