Respiratory Flashcards
PE of asthama?
labs?
Allergic: Eosinophilic inflammation - in blood work
Expiratory wheeze or rhonchi
Hx questions to ask pt with suspected asthma?
How frequent cough, wheezing, difficulty breathing Nighttime awakening Medication response Activity response Exacerbations required oral steroids
Med must know for tx asthma in pts 6 and older?
NO SABA alone (death in 6 and older), only under age of 5
Asthma differentials?
Allergic rhinitis/sinusitis Respiratory infection GERD Medication induced cough (ACE Inhibitors) COPD Heart Failure Vocal cord dysfunction
GINA Asthma Guidelines
- mild
- moderate
- severe
Mild:- well controlled with PRN alone or with low ICS (6 or older) -> STEP 1/2
Hard to diagnose under 5
Moderate- well controlled with low dose ICS.
-> LABA (STEP 3) SABA prn
Severe: high dose ICS/ LABA, -> remains uncontrolled (Step 4), saba prn
No ICS for kids under 6 y.o ,9
What age is treated as an adult for asthma
Over 6 years
<5 cant do spirometry
Pedi Asthma Differentials
VIral URI
Allergic rhinitis
Foreign body
How to treat pedi asthma? 1-11 years old
- Montelukast chewable
- Neb ICD until able to use inhaler
1-11 y/o
Neb with albuterol
Oral steroid burst : 60 mg/day
Liquid prednisone : 1-2mg/kg/day QAM for 3-10 days
Orapred 15mg/ml (has sorbitol- can make diarrhea worse)
For Rescue only
Not to be used alone, except for < 5 years of age.
Albuterol
Levalbuterol
Used in Combination therapy (long-acting, LABAs)
Salmeterol (Serevent)
Formoterol (Foradil)
Beta 2 Agonists
For Rescue only (short-acting, SABAs).
Acute infection of lower RR tract in infants and young children (common in infant hospitalization)
Agent: RSV, Rhino, adeno, corona
Bronchiolitis (self limiting, most mild)
Dehydration , feeding, lethargy → impending RR failure
Decrease UO
Bronchiolitis
How to manage/ tx bronchiolitis?
Improves itself, most mild and managed at home
Supportive- antipyretics, hydration, bulb syringe
TOXIC appearance
Otitis media, nasal congestion, tons secretions, tachypnea, increase WOB, wheezing, rhonchi, delayed cap refill, displaced spleen and liver d/t lung expansion
bronchiolitis
Inflammation of the trachea and bronchi/ lower tract by definition , caused by viruses or lung irritation
Risk Factors:
Occupational - exposure to irritants
Smoking
Bronchitis- URI
Cough-may or may not have sputum lasting longer than 7 days
Retrosternal pain- behind the sternum—> “chest cold”
Nasal discharge
Sore throat
Low grade fever
Reduction in FEV1
Bronchitis
What to consider in adult with hacking cough lasting > 2 weeks?
consider B. Pertussis
over Bronchitis
Cough and sputum on most days for 3 months of year, two consecutive years
Chronic Bronchitis
How to Tx/ manage Bronchitis?
Cough ____
What is the cause? Sx treatment- 80% improvement without
Cough: dextromethorphan/ benzonotate
Severe cough (bedtime: codine or hyd
Antipyretics
Cough suppressant is controversial- you want to be able to get the sputum out, not suppress it
Bronchodilator - doesn’t help w cough (unless has asthma)
NO ANTIBIOTIC- not likely bacterial - if it is, macrolides (first line)
Stop smoking
Illness of larynx, trachea and bronchi → stridor and barking, Inflammation of UR tract
Risk Factors:
18m-2 y.o
History of past infection - can cause recurrent spasmodic
Worse at night (runs course 3-5 days) Clinical Manifestations: Rhinorrhea Barking cough Fever Accessory muscle use
Croup
WestleyCroup scoring system
*Less than 3 - mild
3-6 -moderate
>6 - severe
PE:
Dyspnea
Tachypnea
Retractions
Stridor - (stridor at rest- foreign body)
Wheezing and rales may be heard if there is additional lower airway involvement.
Croup
Croup Differentials?
How to manage?
Differentials:
- FB aspiration (if stridor on rest)
- Epiglottitis (if drooling)
Management: Racemic epi (Causes vasoconstriction diminishing edema) Corticosteroids Humidifier in mild cases Antipyretic Oral hydration
the maximum rate that person can exhale in a short, maximal expiratory effort after a full inspiration
Peak Flow
Most common cause of Bronchiolitis
RSV
Well-controlled with as-needed reliever medication alone or with low-intensity controller treatment such as low-dose inhaled corticosteroids (ICSs), leukotriene receptor antagonists, or
chromones
Mild asthma
Well-controlled with low-dose ICS/long-acting beta2-agonists
LABA
Moderate Asthma
Requires high-dose ICS/LABA to prevent it from becoming
uncontrolled, or asthma that remains uncontrolled despite this
treatment
Severe asthma
GINA no longer recommends ______ for first-line use in asthma except in children
aged under 5 years (where evidence is lacking) and where a trial of ICS should be
used in those not responding to as-needed
SABAs
for as-needed relief of symptoms, GINA’s preferred choice of reliever is _____ for adults and adolescents over the age of 12 and _____ taken as needed together with a ____ in children aged 6–11 years
ICSs in combination with formoterol for adults and adolescents over the age of 12
ICS taken as needed together with a SABA in children aged 6–11 years
long-acting bronchodilator with rapid action
ICS-formoterol
For Rescue only (short-acting, SABAs).
• Not to be used alone, except for < 5 years of age.
Beta2 Agonists
• Albuterol
• Levalbuterol
Used in Combination asthma therapy (long-acting, LABAs)
Beta2 Agonists
• Salmeterol (Serevent)
• Formoterol (Foradil)
Exercised Induced Asthma tx
- Warm up
- Scarf over mouth in cold
- SABA 2 puffs 5 mins before exercise
- LABA
Acute Exacerbation Management for > 12 years
• Oral steroid burst 3-10 days • Prednisone up to 60mg AM • Methylprednisolone 40-60mg AM • Medrol dosepak 4mg tablets (84mg total divided over 6 days = inadequate dosing)
Acute Exacerbation Management for ages 6-11
• Chewable Montelukast (Singulair)
• Nebulizer for ICS until able to use inhaler
• Budesonide 0.25mg/2mL to 1mg/day; may
divide into BID
asthma exacerbation Ages 1-11
