Alyssa Brzenski MD ENT PATHOLOGY

Case A 34 week old premature baby boy was born vaginally to a young mother with chorioamnioitis. At birth the baby was tachypneic and required intubation. Blood cultures were performed and came back positive, so the NICU started the baby on IV Penicillin and Gentamycin for 14 days. He was given surfactant x 3 doses and remained intubated for 7 days. Upon finishing his antibiotic regime, he was allowed to go home with his mother weeks later, the mother appears at the pediatricians office with the baby and complains that “the baby turns blue, he’s noisy when he breathes and she has difficulty feeding him.”

“Noisy Breathing” Definition

Differential Diagnosis

Evaluation of Stridor

Laryngomalacia- The Facts Most common laryngeal anomaly and cause of stridor (54-75%) DEFINITION: “Flaccid laryngeal tissue and inward curling of supraglottic structures during inspiration. There is a fluttering inspiratory stridor that worsens with agitation, crying, feeding or supine.” Begins in 1 st weeks of life and peaks at 6-8 months

Normal Pediatric Anatomy

Laryngomalacia

Treatment

Supraglottoplasty

Before and After

CO2 vs YAG Laser TypeAdvantageDisadvantageOther CO2 LaserPrecise; Decreased Post-op Edema Takes longer for bigger areas Invisible on it’s own, combined with helium-neon laser Nd:Yag LaserGreat CoagulationDeep penetration/surroun ding tissue damage Able to go through liquids, can be used in fluid filled areas

Additional Management Dexamethasone Possible Post-op Intubation Racemic Epi PPI H2 Blocker

Subglottic Stenosis Aquired Subglottic Stenosis From prolonged intubation or high pressure on the tracheal mucosa Congenital Subglottic Stenosis Cricoid diameter less than 3.5mm Result of malformation of the cricoid cartilage

Vocal Cord Paralysis Inspiratory or biphasic stridor, weak cry Causes Birth trauma Central (Arnold-Chiari, Brainstem compression) neurologic diseases Thoracic disease or procedures (PDA ligation, aortic arch surgery)
