Area of Science:

• Pediatrics
• Infectious Diseases
• Critical Care Medicine

Background:

• Bronchiolitis is a common viral respiratory infection in infants.
• Major medical interventions (MMIs) are sometimes required for severe cases.
• Understanding the need for and timing of MMIs is crucial for timely management.

Purpose of the Study:

• To examine the need for and timing of major medical interventions (MMIs) in infants under 6 months with bronchiolitis.
• To identify risk factors associated with requiring MMIs.

Main Methods:

• Retrospective review of medical records for 353 infants diagnosed with bronchiolitis.
• Definition of MMI included supplementary oxygen, intravenous fluids, intravenous antibiotics, or ICU admission.
• Analysis of patient demographics, clinical data, and outcomes.

Main Results:

• 19% of infants required an MMI, and 3% experienced apnea.
• Apnea was more common in infants under 2 months, particularly those with RSV and prematurity.
• Risk for MMI persisted up to 5 days post-onset; RSV positivity (OR 11.5) and fever >38°C (OR 3.5) predicted MMI, while higher initial oxygen saturation reduced risk (OR 0.7).

Conclusions:

• Infants under 6 months with bronchiolitis have the highest likelihood of needing MMIs within the first 5 days of illness.
• Early identification of risk factors like RSV infection and low oxygen saturation can guide clinical decision-making.
