Q

Asthma management: (1) evaluate asthma severity (new dx, not on long-term control meds)
-how is this determined?
-parent/caregiver recall
-what does more frequent and intense exacerbations cause?

A

-determined by assessment of BOTH impairment and risk
-assess impairment domain by patient’s/caregiver’s recall of previous 204 weeks and spirometry –> assign severity to the most severe category in which any feature occurs
-more frequent and intense exacerbations = greater underlying disease severity

  4. pharmacologic agents (two categories)
54
Q

what do NAEPP recommendations emphasize with therapy?

A

recommendations emphasize daily anti-inflammatory therapy with inhaled corticosteroids as the cornerstone of treatment of persistent asthma

55
Q

asthma: quick relief medications
-SABA: types (meds), use, MOA, mild/mod sx, severe sx, nebulized tx

A

-albuterol, levalbuterol, bitolterol, pirbuterol, terbutaline
-most effective bronchodilators; most effective during exacerbations
-relaxes the smooth muscles –> prompt increase in airflow and decrease in sx
-1-2 puffs usually sufficient
-higher doses of 6-12 puffs every 30-60min of albuterol by MDI or 2.5mg neb is equivalent bronchodilation
-DOSE NOT offer more effective delivery but providers higher doses (usually nebulized tx doses are 25-30x higher; single activation MDI 0.09mg-albuterol. Standard dosing of inhalations from an MDI will often be insufficient in the setting of an acute exacerbation)

56
Q

SABA administration before exercise
-what does it prevent?

A

prevents exercise induced bronchoconstriction

57
Q

what does repetitive ABA administration promote?

A

produces incremental bronchodilation

58
Q

alternatives if SABA doesn’t work for asthma

A

-anticholinergics: ipratropium bromide is the inhaled drug of choice for pts with intolerance to beta 2 agonist or with bronchospasms due to beta blockers meds despite being less effective than beta 2 agonists (decreases mucus gland hypersecretions; reverse mediated bronchospasm but NOT allergen or exercise induces asthma)
-corticosteroids: systemic steroids are PRIMARY tx for patients with moderate to severe asthma exacerbations who do not respond promptly and completely to SABA. Reduces rate of relapse and speeds resolution of airflow obstruction
*outpatient burst therapy: 0.5-1mg/kg/d (typically 40-60mg) in 1-2 doses for 3-10d
*severe exacerbations: require 1mg/kg of prednisone or methylprednisone every 6-12hrs for 48 hrs or until FEV1 returns to 50% predicted
-antimicrobials: multiple studies suggest infections with viruses (rhinovirus) and bacteria (M pneumoniae and C pneumoniae) predispose exacerbations. Consider when likelihood of acute bacterial RTI. Routine use in asthma exacerbations is not recommended.

67
Q

what is the 1st line treatment agent used for patients with persistent asthma?

A

inhaled corticosteroids

68
Q

inhaled corticosteroids (asthma treatment)

A

long term controller; anti-inflammatory agent
-preferred first line tx for all pts with persistent asthma
-most pts use twice daily dosing –> provides adequate control
-maximum response from inhaled corticosteroids may not be observed for months
-dry powder inhalers: not used w/ an inhalation chamber (chamber with mouth rinsing DECREASES side effects)
-systemic effects may be seen w/ high dose of steroids

69
Q

systemic (oral) corticosteroids (asthma treatment)

A

long term controller; anti-inflammatory agent
-most effective in achieving prompt control of asthma during exacerbations in children and adults
-alternating days (treatment plan) is preferred than daily tx
-requires concurrent treatment with calcium and vit D to prevent corticosteroid induced bone mineral loss; check bone density after 3 months
-avoid rapid discontinuation to prevent adrenal insufficiency
-

70
Q

what (med) is the most effective in achieving prompt control of asthma during exacerbations in children and adults?

A

systemic (oral) corticosteroids

71
Q

-provide the equivalent to what would be if doubled the inhaled corticosteroids
-combo inhalers of formoterols short onset and budesonide

73
Q

anticholinergics agents, short acting muscarinic agents (SAMA) and long acting muscarinic agents (LAMA)

80
Q

Mild asthma exacerbation
-characterized by…
-4 components to exacerbation
-**doubling dose

A

-characterized by only minor changes in airway fx (PEF (peak expiratory flow) >80%)

-many patients respond to quick and fully to inhaled SABA
-sometimes need continuous SABA at increased doses
-if not taking an inhaled corticosteroid, can initiate one
-if patient is taking inhaled steroid –> can initiate oral corticosteroid

81
Q

Moderate asthma exacerbation
-goal of treatment
-SABA and corticosteroid role
-what correlates to severity of asthma exacerbation

A

-correct hypoxemia, reverse airflow obstruction, and reduce likelihood of reoccurrence of obstruction
-MAIN IMPORTANCE is correction of hypoxemia through supplemental oxygen

-Continue inhaled SABA and early administration of corticosteroids
-systemic corticosteroids should be given if peak flow is >70% of baseline or patient who doesn’t respond to several SABA treatments

-improvement of FEV1 after 30 minutes

Q

AIRQ
-definition
-what is it used along side?

A

can help you and your patient determine whether their asthma is well controlled

Asthma impairment and risk questionnaire
-for patients age >equal 12 years, only the AIRQ is validated as a single instrument assessing both impairment and control
-10 yes or no questions that evaluate sx, social and physical activities, exacerbations, related healthcare resources utilization, perception of asthma control, and use of rescue (reliever) medications

-a score of 0 or 1 indicates asthma is well controlled
-score of 2-4 indicates asthma is not well controlled
-score of 5-10 indicates asthma is very poorly controlled

*identifies patients with exacerbations requiring treatment with oral corticosteroids or emergency department/unplanned office visits or hospitalizations for asthma that are not assessed by many other asthma control tools

*used along side the asthma checklist

100
Q

asthma checklist

A

a management assessment checklist used in conjunction with an asthma control questionnaire can facilitate a thorough investigation and optimization of asthma control
-this checklist includes factors such as medication adherence, use of an action plan, psychological issues, vaccination, and suggestions for specialty care referral

101
Q

Assessing Asthma Control
-Asthma Control Test

A

Questionnaire that assesses a patient’s asthma control. For patients 12 years and older who have been diagnosed with asthma. If score is 19 or less, asthma may not be controlled as well as it should be. Talk to your doctor.

102
Q

Acute (severe) asthma exacerbation
-how serious is this?
-what three things should patient be immediately put on?

A

-can be life-threatening
-all patients should immediately get O2, high dose of inhaled SABA and systemic corticosteroids

103
Q

Acute (severe) asthma exacerbation
-management: oxygen, SABA, regular control meds, oral corticosteroids, IV mag, assess
-when can you D/C patient home?
-what is contraindicated?

A

-oxygen saturation >90% or PaO2>60mmHg
-frequent delivery of high-dose SABA: albuterol inhaler 2-6 puffs, repeat in 20 min x3 (may need to continue SABA q 3-4 hours for 24-48hrs)
-continue/adjust regular control meds (stepwise) –> ipratropium bromide reduces rate of hospitalizations when added to inhaled SABA in pts with mod to severe asthma
-start short course oral corticosteroids (prednisone, methylprednisolone, or prednisolone in either single dose or divided BIDx7days (no need to taper)
-IV magnesium: FEV1<25%
-assess use of regular medications –> EDUCATE
-assess immunization status: influenza, pneumococcal vaccine
-can discharge to home if PEF or FEV1 has returned to 60% or more of predicted

-contraindicated: mucolytic agents (may worsen cough and airflow; anxiolytic and hypnotics (due to resp depression)

104
Q

Treatment for all cases of asthma
-quick acting

A

quick acting “rescue” inhaler = SABA

albuterol can be given as a MDI (90mcg/spray) or nebulized (available as 0.63 or 1.25mg/3mL of saline)
-dose: 0.05mg/kg (max 5mg) 20kg = 1 mg
-use 1 puff of MDI or 1 neb - may repeat q 20 min x 3 for acute exacerbation of sx

105
Q

how does a patient use an asthma action plan?

A

used for daily management that includes instructions and measures to take in response to specific change in status

106
Q

reasons to refer someone with asthma

A

-atypical presentation
-comorbid conditions
-suboptimal response to therapy
-not meeting asthma goal after 3-6 months
-requires high dose corticosteroids for control
-more than 2 courses of oral prednisone in past 12 months
-any life-threatening asthma exacerbation requiring hospitalization in last 12 months
-social/psych issues interfering with asthma management

107
Q

when to admit patient with asthma to the hospital

A

poor response to SABA after 2 treatments 20 minutes apart
-hypoxia: O2 sat <95% on RA
-marked breathlessness: inability to speak in sentences
-use of accessory muscles
-changes in alertness
-PEF of <50% personal best!!!!!!!
