Bronchiolitis (peds): Difference between revisions
Revision as of 20:45, 31 March 2015
- <2yr old (peak 2-6mo age)
- Respiratory Syncytial Virus (RSV) causes ~70% of cases
- Preemies, neonates, congenital heart dz are at risk for serious disease
- Peaks in winter
- Duration = 7-14d (worst during days 3-5)
- Inflammation, edema, and epithelial necrosis of bronchioles
- Rhinorrhea, cough, irritability, apnea (neonates)
- Assess for dehydration (tachypnea may interfere with feeding)
- Rapid RSV
- Obtain if <1mo old
- If positive then admit pt
- Not routinely necessary
- May lead to unnecessary use of abx (atelectais mimics infiltrate)
- Consider if
- Diagnosis unclear
- Critically ill
- Not routinely necessary
- Infants <60 days with RSV bronchiolitis and fever
- Randomized controlled trials of bronchodilater or corticosteroid therapy have shown mixed results. Bronchodilators could aggravate the symptoms.
- The AAP guidelines also state that it is reasonable to not perform continuous oximetry on infants and children with bronchiolitis
- O2 (maintain SaO2 >90%)
- oxygen saturation alone should not dictate admission
- Suction nares / nasal saline drops
Although AAP recommends as a possible intervention. the SABRE trial found no support the use of nebulised HS in the treatment of acute bronchiolitis in regard to time to discharge or adverse events. 
- Nasopharyngeal suctioning may temporarily relieve symptoms
- Do not perform deep suctioning since it will increase length of stay with no added benefit
- Age <3months
- Preterm (<34wks)
- Underlying heart/lung disease
- Initial SaO2 <90%
- Sa02 alone should not be used as the only factor for admission
- Unable to tolerate PO
