1

Defines the narrowest portion of the upper airways in children <10 yrs

Cricoid cartilage

2

Bark-like or brassy cough

Croup

3

Harsh, high-pitched respiratory sound which is usually inspiratory but can be biphasic

Stridor

4

Most acute infections of the upper airway are caused by ___ with the exception of diphtheria, bacterial tracheitis, and epiglottitis

Viruses

5

Account for ~75% of infectious upper airway obstruction

Parainfluenza

6

Croup peaks at what age

2 y/o

7

Croup is aka

Laryngotracheobronchitis

8

MCC of pediatric epiglottitis in vaccinated children

S. pyogenes, S. pneumoniae, S. aureus; Hib has been reduced due to vaccination

9

MCC of croup

Viruses

10

MC form of upper airway osbtruction

Croup

11

Barking cough, hoarseness, inspiratory stridor

Croup

12

T/F Symptoms of croup are worse at night

T

13

T/F Croup is a clinical diagnosis and does not require a radiograph of the neck

T

14

Radiographs of the neck in croup can show the typical ___

Subglottic narrowing or steeple sign

15

Accepted treatment for moderate to severe croup which causes constriction of the precapillary arterioles through β-adrenergic receptors, causing fluid resorption and decreased edema

Nebulized racemic epinephrine

16

T/F Effectiveness of oral corticosteroids in viral croup is well-established

T

17

Upper airway obstruction: Drooling with hyperextended neck in an attempt to maintain the airway

Acute epiglottitis

18

Upper airway obstruction: Tripod position

Acute epiglottitis

19

Upper airway obstruction: Stridor is a late finding

Acute epiglottitis

20

T/F In acute epiglottitis, no other family members are ill with acute respiratory symptoms

T

21

Upper airway obstruction: Cherry red epiglottis

Acute epiglottitis

22

T/F Diagnosis of acute epiglottitis REQUIRES visualization of a large cherry red swollen epiglottis by laryngoscopy

T

23

Classic radiographic picture of child who has epiglottitis

Thumb sign

24

T/F Establishing an airway is indicated in patients with epiglottitis regardless of degree of apparent respiratory distress

T

25

Reason why it is necessary to establish an airway in epiglottitis regardless of degree of respiratory distress

As many as 6% of children without an artificial airway die compared to <1% with artificial airway

26

T/F Children with epiglottitis are intubated for 2-3 days because response to antibiotics is usually rapid

T

27

Choices for empiric therapy of epiglottitis

IV Ceftri, Cefotax, Merop (BECAUSE 10-40% of Hib are resistant to Ampicillin)

28

Indications for household members prophylaxis in cases of epiglottitis

1) <48 months of age incompletely immunized 2) <12 months with no primary vaccination series 3) Immunocompromised child

29

Medication used for prophylaxis in cases of epiglottitis

Rifampin

30

MCC of acute infectious laryngitis

Virus
