Learning Objectives

After listening to these episodes listeners will…

  • learn what the recent literature on bronchiolitis shows about hypertonic saline, pulse oximetry, invasive suctioning high-flow nasal cannula.
  • discuss treatments and testing options to avoid doing routinely: CXR, viral testing systemic steriods, inhaled bronchodilators, invasive suctioning (NEW), continuous oximety (NEW).
  • discuss when to use High Flow Nasal Cannula, what flow rates to provide and when it is not helpful.

Notes Episode 2-4

Dr. Knochel mistakenly mentioned Pediatric Grand Rounds would be March 8th.  The correct date is Thursday, March 7th at 8 am.  Link below.

Regarding flu swabbing guidelines:

Each lab may differ on acceptable specimens, even given these CDC guidelines.   Deep nasal (midturbinate) swab is apparently find for flu testing, but we’re not sure about other viruses.

For respiratory viral testing, Primary Children’s laboratory does not accept nasal swab + throat swab combo or deep nasal swab (yet), but we do take (with proper labeling & order) the following:

BAL, trach aspirate, Nasopharyngeal wash (in sterile saline), nasopharyngeal swab (UTM or M4 medium), nasopharyngeal aspirate (UTM or M4 medium), sputum sample (older kids who can hack up sputum or expectorate an induced sputum specimen).

Of course, a good question to ask before obtaining respiratory panel testing is:  “will this change my management?”  Usually for bronchiolitis the answer is no, unless you suspect influenza and will treat if positive, or if you think it’s pertussis.
