Counseling for RSV Bronchiolitis Prevention in a 29-Week Premature Infant
This infant qualifies for palivizumab (Synagis) prophylaxis and should receive it immediately—this is a clear indication based on gestational age alone, and the medication reduces RSV hospitalization by 55% in high-risk infants. 1, 2
Why This Baby Qualifies for Prophylaxis
Infants born before 29 weeks, 0 days' gestation who are younger than 12 months at the start of RSV season should receive palivizumab prophylaxis. 1, 2, 3
This 2-month-old baby born at 29 weeks meets the primary eligibility criteria regardless of any other factors. 1, 4
The history of NICU stay and oxygen requirement further supports this indication, though gestational age alone is sufficient. 1
What Palivizumab Does
Palivizumab reduces RSV-related hospitalization by 55% overall in high-risk infants (from 10.6% to 4.8% hospitalization rate). 5, 6
In premature infants without chronic lung disease, the reduction is even more dramatic at 78% (from 8.1% to 1.8%). 6
The medication provides passive immunity through monthly injections and is only for prevention—it does not treat active RSV infection. 1, 7, 4
Dosing Schedule to Recommend
Administer 15 mg/kg intramuscularly every 30 days for a maximum of 5 monthly doses throughout RSV season. 1, 2, 4
In the Northern Hemisphere, initiate in November and continue through March, providing protection through April. 1
If starting later in the season, fewer doses may be needed—the goal is coverage through the end of RSV season. 1
The first dose should be given prior to commencement of RSV season or as soon as possible if already in season. 4
Safety Profile to Reassure the Mother
Palivizumab results in little to no difference in adverse events compared to placebo (91 vs 84 per 1000 participants). 5
Injection site reactions are uncommon (2.7%) and typically consist of mild, transient erythema. 6
The medication is safe and well-tolerated, with only 0.3% of children discontinuing due to adverse events. 6
Palivizumab does not interfere with routine childhood vaccinations—all scheduled immunizations should proceed as normal. 2
Additional Prevention Measures
Keep the infant away from crowds and situations where exposure to infected people cannot be controlled. 3
Practice careful hand hygiene—this is the cornerstone of reducing healthcare-associated RSV transmission. 1, 3
Restrict participation in group childcare during RSV season when feasible. 3
Eliminate all exposure to tobacco smoke. 3
Ensure all household contacts receive influenza vaccine and other age-appropriate immunizations. 3
Critical Points to Emphasize
If the infant develops RSV infection despite prophylaxis, continue monthly doses throughout the season—breakthrough infection does not mean prophylaxis has failed for future exposures. 4
However, if the infant is hospitalized with confirmed RSV, discontinue prophylaxis as the likelihood of a second RSV hospitalization in the same season is extremely low (<0.5%). 1, 2
The medication only prevents severe RSV disease—it does not prevent all respiratory infections or reduce wheezing episodes. 1, 2
What to Expect Without Prophylaxis
Premature infants like this baby face significantly elevated risk of RSV hospitalization during their first RSV season. 5, 8
RSV bronchiolitis can lead to intensive care admission, mechanical ventilation, and prolonged oxygen requirements in high-risk infants. 6
Treatment options for established RSV infection are limited to supportive care only—there are no effective antiviral therapies. 7, 9
