What is the treatment approach for Respiratory Syncytial Virus (RSV) in the Emergency Department (ED)?

RSV Treatment in the Emergency Department

Primary Treatment Approach

RSV treatment in the ED is primarily supportive care, focusing on hydration assessment and oxygen supplementation when oxygen saturation falls persistently below 90%. 1 There is no specific antiviral therapy indicated for routine ED management of RSV infection in otherwise healthy children. 1

Core Supportive Measures

Hydration and Oxygenation

• Assess and maintain adequate hydration and fluid intake for all RSV patients 1
• Provide supplemental oxygen if oxygen saturation falls persistently below 90% in previously healthy infants 1
• As clinical improvement occurs, continuous SpO2 monitoring is not routinely needed, though premature infants and those with hemodynamically significant heart or lung disease require close monitoring during oxygen weaning 1

Symptomatic Relief

• Use acetaminophen or ibuprofen for fever or pain management 1
• Nasal saline irrigation may provide symptomatic relief in adults with upper respiratory symptoms 1

What NOT to Use in the ED

Medications Without Benefit

• Do NOT use bronchodilators routinely - the American Academy of Pediatrics recommends against routine bronchodilator therapy without documented clinical improvement 1
• Do NOT use corticosteroids - routine use is not recommended in bronchiolitis management 1
• Do NOT use ribavirin routinely - it should not be used in children with bronchiolitis except in severely immunocompromised patients, hematopoietic stem cell transplant patients, or mechanically ventilated infants with documented severe RSV infection 1, 2
• Do NOT use antibacterial medications unless specific indications of bacterial co-infection exist 1
• Do NOT use palivizumab for treatment - it has no therapeutic benefit for established RSV infection and is only approved for prevention in high-risk infants 1

Diagnostic Approach

Rapid Testing

• Perform rapid diagnostic testing (immunofluorescence or ELISA) to document RSV infection, especially during RSV season (December-March) for pediatric patients and immunocompromised adults with respiratory illness 3, 2
• RSV infection should be documented by rapid diagnostic method before or during the first 24 hours of treatment in high-risk populations 1, 2
• Respiratory virus testing (including RSV, influenza, parainfluenza, adenovirus, and human metapneumovirus) and chest radiography are indicated for patients with upper respiratory symptoms and/or cough 3

Infection Control in the ED

Hand Hygiene - The Most Critical Intervention

• Hand decontamination before and after direct contact with patients is the single most important measure to prevent transmission 3, 1
• Use alcohol-based rubs as the preferred method for hand decontamination 3, 1
• Wash hands after contact with patients or respiratory secretions, after touching potentially contaminated fomites, and after removing gloves 3

Personal Protective Equipment

• Wear gloves while handling patients with confirmed or suspected RSV infection and when handling potentially contaminated fomites 3
• Change gloves between different patients and after handling respiratory secretions 3
• Wear a gown if clothing could be soiled by respiratory secretions (especially when handling infants) 3
• Change gown after contact and before caring for another patient 3

Special Populations Requiring Different Management

High-Risk Patients Requiring Admission Consideration

• Premature infants 1
• Infants with hemodynamically significant heart or lung disease 1
• Immunocompromised patients (including those receiving chemotherapy) 3
• Patients with severe combined immunodeficiency (SCID) 1

When to Consider Ribavirin (Inpatient Decision)

Ribavirin is FDA-approved for hospitalized infants and young children with severe lower respiratory tract RSV infection, but treatment decisions should be made by the admitting team, not in the ED 2. The drug is specifically considered for:

• Hematopoietic stem cell transplant patients with RSV lower respiratory tract infection 1
• Severely immunocompromised patients 1
• Mechanically ventilated infants with documented severe RSV infection 1

Treatment with ribavirin is most effective when instituted within the first 3 days of clinical illness 2

Disposition and Escalation Criteria

Consider Admission for:

• Inability to maintain adequate hydration 1
• Persistent oxygen saturation below 90% despite supplemental oxygen 1
• Severe respiratory distress 1
• High-risk patients (premature infants, those with cardiopulmonary disease, immunocompromised) 1

Consider ICU Transfer for:

• Failure to maintain SaO2 >92% in FiO2 >60% 1
• Shock 1
• Severe respiratory distress with rising PaCO2 (>6.5 kPa or approximately 49 mmHg) 1

Critical Pitfalls to Avoid

• Overuse of antibiotics without evidence of bacterial co-infection - this is a common error that contributes to antimicrobial resistance 1
• Continuing bronchodilator therapy without documented clinical improvement 1
• Inadequate infection control measures leading to nosocomial transmission - hand hygiene is paramount 1
• Using palivizumab as treatment - it has no therapeutic role in established infection 1
• Restricting healthcare workers with active upper respiratory symptoms from caring for high-risk infants - symptomatic staff should not care for vulnerable patients 3
