DDx for wheeze 4 common and a few uncommon
common 1. asthma 2. bronciolitis 3. PNA - fever cough malaise 4. GERD uncommon 1. CF - prolonged and unresponsive 2. foreign body - sudden onset 3. mass 4. CHF - FTT 5. tracheobronchial abnormalities
def. of asthma
airway hyperactivity, bronchospasm, inflammation, and reversible airway obst
crit. for determining if well controlled

PEF variations of
important asthma Hx
- severity of episode
- might Sx
- eposures
- hospital and ICU admissions
- fam Hx
invest. for asthmas
- pulse oximetry
- consider ABG if increasing O2 required
- CXR if first time or atypical
- 6 can do spirometry
spirometry def of asthma
FEV/FVC
mgmt of asthma
- humid O2 if
when to hosp. for asthma
absolute
- requires O2
DC instructions for asthma
- B2 agon q4h, 1-2 days
- dex to complete course
- inhaled cort. for at least 3 weeks or seaon
- educations
- reassess in 24-48 hrs
def. of bronchiolitis
self limiting seasonal viral infection of lower tract in child
Hx of bronchilitis
- prodrome of coryza, worsening cough
- low oral intake
- irritable
- resp distress
invest for bronchioitis
- Hx and Phx
- pulse ox
- NP for viral swabs if in hosp
- blood work and CXR NOT necc.
mgmt of bronciolitis
- O2 if sats
when to hosp. for bronchiolitis
absoute - O2 requirements - dehydration evident - Hx of apnea relative - young
def, of CF
- auto reccessive
- mutation of gene causes abnormal Cl - thick secretions
- changes to epithelium of airway, panc ducts, biliary tree, vas def. and sweat glands
present of CF
resp - cough - lower airway colonization - endobronch. infection - hypoxemia upper airway - pansinusitis - nasal polyps GI - protein and fat malabsorption - meconium ileus - distal intestinal obst. - abst. jaundice - rectal prolapse
Dx of CF
- part of newborn screen
- if test is positive, then do sweat chloride test
- CFTR gene mutation analysis
CF complications
lung disease - progressive obst. and inflammaiton lung infection - Staph, H flu, pseudo panc. disease intestinal disease hepatobiliary disease infertility in males
mgmt of CF
methods to promote clearance of airways
def. epiglotitits
acute cellulitis of epiglottis
- most common H flu
death with no Tx

Distress
Phx of epiglot

- classic tripods
- stridor
- drolling
- tender to palpate hyoid
- tachy
mgmt of epi
- ENT stat
- xray - thumbprint sign
- secure airway at nearest hosp
