Management of Respiratory Syncytial Virus (RSV) Infection
Primary Approach to Management
The primary approach to managing Respiratory Syncytial Virus (RSV) infection is supportive care, including maintaining adequate hydration, providing supplemental oxygen if needed, and monitoring respiratory status. 1 This is because there are no specific antiviral treatments routinely recommended for most patients with RSV infection.
Supportive Care Measures
Supportive care remains the cornerstone of RSV management and includes:
- Oxygen supplementation: Provide supplemental oxygen if SpO₂ is below 90% 1
- Hydration maintenance: Ensure adequate fluid intake, which may require IV fluids in severe cases 1
- Respiratory monitoring: Monitor respiratory rate, work of breathing, and oxygen saturation 1
- Nasal suctioning: Clear nasal passages to improve breathing and feeding 1
- Positioning: Slightly elevated head position while sleeping 1
- Cool-mist humidifier: May help loosen secretions 1
Special Considerations for High-Risk Populations
For specific high-risk populations, additional interventions may be considered:
Immunocompromised Patients
- Ribavirin (aerosolized or systemic) may be considered for immunocompromised patients at high risk for severe RSV disease 2, 1
- Combination therapy with ribavirin plus IVIG may benefit allogeneic hematopoietic stem cell transplant patients with RSV lower respiratory tract infectious disease 2
Infants at High Risk for Severe Disease
- More intensive monitoring and lower threshold for hospitalization 1
- Consider hospitalization if the infant develops:
- Oxygen saturation ≤92% on room air
- Significant respiratory distress
- Inability to maintain adequate hydration
- Apnea episodes
- Lethargy or altered mental status 1
Treatments to Avoid
Several interventions are not recommended due to lack of evidence:
- Bronchodilators: Not recommended for routine use in RSV bronchiolitis 1
- Antibiotics: Should not be used unless there is specific evidence of bacterial co-infection 1
- Corticosteroids: Not routinely recommended for RSV bronchiolitis 1
Prevention Strategies
Prevention is a critical component of RSV management:
Infection Control Measures
- Hand hygiene: Critical before and after patient contact 2, 1
- Contact isolation: For hospitalized patients with RSV 2
- Cohorting: Group infected patients together when private rooms are unavailable 2
- Personal protective equipment: Gloves and gowns during contact with RSV-infected patients 2
Immunoprophylaxis
For high-risk infants, immunoprophylaxis options include:
Palivizumab: A monoclonal antibody indicated for prevention in high-risk infants, including:
- Premature infants ≤35 weeks gestational age who are 6 months or younger at the beginning of RSV season
- Children ≤24 months with bronchopulmonary dysplasia requiring medical treatment within the previous 6 months
- Children ≤24 months with hemodynamically significant congenital heart disease 3
Nirsevimab: A newer long-acting monoclonal antibody recommended for:
- All infants <8 months born during or entering their first RSV season
- Infants and children 8-19 months at increased risk entering their second RSV season 1
Common Pitfalls to Avoid
Overuse of antibiotics: RSV is a viral infection; antibiotics should only be used if bacterial co-infection is suspected 1
Excessive testing: RSV bronchiolitis remains a clinical diagnosis; routine viral testing is not recommended for typical cases 1
Continuous pulse oximetry: Not required in all cases and may lead to prolonged hospitalization 1
Delayed recognition of deterioration: Infants under 2 months are at higher risk for severe disease and require closer monitoring 1
Inadequate infection control: Proper hand hygiene and isolation precautions are essential to prevent nosocomial spread 2
RSV management primarily focuses on supportive care while preventing complications and spread of infection. For high-risk populations, specific preventive measures like immunoprophylaxis should be considered according to current guidelines.
