Treatment
Medical Care
- Antibiotics are not necessary in the child with asthma. Oral corticosteroids, together with frequent inhaled bronchodilators and continued high-dose inhaled corticosteroids, address the underlying inflammation and bronchospasm.
- A recent study determined that noninvasive medical treatment can be simply and easily used to substitute bronchoscopic treatment in small hospitals.2
- If the child with atelectasis has cystic fibrosis, aggressive antibiotic therapy is indicated in conjunction with chest physical therapy and postural drainage. A mucous plug from other causes may respond to chest physical therapy and postural drainage. See Cystic Fibrosis for a more detailed discussion of the therapy for this disorder. Instillation of DNAse, either through a nebulizer or through a bronchoscope, may help remove the secretions more rapidly and completely.
- Children with neuromuscular disease, children who have undergone surgery, and children with chest pain benefit from chest physical therapy to reduce the likelihood of developing further atelectasis; whether these procedures treat the existing atelectasis is not clear. In children with neuromuscular disease, using the mechanical ex-insufflator (CoughAssist Device) is helpful in preventing atelectasis and may produce enough of a cough to clear the airways.
- If pain is causing the atelectasis, adequate pain therapy is mandatory. Administering adequate pain therapy is probably more important than the possibility of decreased minute ventilation from the pain therapy in this situation.
Surgical Care
- If the patient is severely affected by the atelectasis and response to therapy of the underlying disorder is suboptimal, bronchoscopic removal of secretions, mucous plugs, or both may be helpful. Both N- acetyl cysteine and rhDNase have been used with some success in facilitating the removal of mucous plugs in the airways. Both have been used in patients with cystic fibrosis and have had some success in patients without cystic fibrosis as well.
- DNAse has been used in cystic fibrosis to facilitate transport of the abnormal secretions. DNAse has been successfully used in other patients with acute atelectasis. However, the success of the medication depends on the amount of DNA in the secretions, which is generally not known beforehand. Although N -acetyl cysteine has been used as a mucolytic both in nebulizer and bronchoscope forms, success has not been validated in controlled studies. Furthermore, it has the potential to cause significant bronchospasm.
Consultations
- A pediatric pulmonologist may help diagnose and treat the underlying disorder and may also be helpful if bronchoscopy is necessary.
Activity
- As long as the child's oxygenation status is not compromised, activity should not be limited.
Medication
Tailor therapy to the underlying disorder whenever possible. Antibiotics are not necessary if the child has asthma and uses oral corticosteroids, frequent inhaled bronchodilators, or high-dose inhaled corticosteroids to address the underlying inflammation and bronchospasm. For more information, see Asthma. The National Asthma Education and Prevention Program (NAEPP) provides detailed information regarding managing children or adults with asthma. For more information see the NAEPP guidelines.3
If the child has cystic fibrosis, aggressive antibiotic therapy is indicated in conjunction with chest physical therapy and postural drainage. In children with cystic fibrosis, reducing the load of Pseudomonas species in airways facilitates airway clearance. See Cystic Fibrosis for a more complete discussion on the indications for antibiotics, antibiotics used, and dosing schedule in these patients.
Bronchodilators
These agents decrease muscle tone in the small and large airways in the lungs, thereby increasing ventilation. They are used in children with asthma and are potentially helpful in children with cystic fibrosis.
Albuterol (Ventolin HFA, Proventil HFA, ProAir HFA)
Relaxes bronchial smooth muscle by action on beta2-receptors with little effect on cardiac muscle contractility. First-line bronchodilator that should be used with spacer if using metered dose inhaler.
Adult
2-5 inhalations (90 mcg/actuation) PO qid or q2-3h prn cough or wheeze
Pediatric
Administer as in adults
When MDI is used with valved holding chamber, a nebulizer has no advantage
Actions are antagonized by beta-antagonists (eg, propranolol); concomitant administration of sympathomimetics may enhance cardiovascular side effects
Documented hypersensitivity
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
May cause tremor or tachycardia
Systemic corticosteroids
These agents effectively reduce airway inflammation in asthma and cystic fibrosis, which allows easier mobilization of secretions. These also reduce airway reactivity, which might increase propensity to atelectasis.
Prednisone (Deltasone) or prednisolone (Prelone, Orapred)
Corticosteroids that are first-line therapies in the United States.
Both are available in tab and syr; Orapred is available in PO dissolving tab. When choosing syr for children, prednisolone syr is more palatable than prednisone syr.
Adult
5-60 mg/d PO qd or divided bid/qid
Pediatric
2 mg/kg/d PO divided bid; not to exceed 30-40 mg PO bid; tapering schedule necessary if used >10 d
Barbiturates, phenytoin, or rifampin may decrease prednisone effectiveness
Documented hypersensitivity; serious infections (excluding meningitis and septic shock) and fungal infections; varicella infections; diabetes (caution)
Pregnancy
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Precautions
Administer with meals to decrease GI upset; early onset adverse effects include glucose intolerance, hypertension, agitation, and indigestion; late-onset adverse effects include immune suppression and increased susceptibility to sepsis, adrenal suppression, hypertension, urinary calcium loss and osteopenia, and gastric irritation and bleeding; lower dose as quickly as possible to reduce adverse effects and complications; prolonged use might be advisable on an alternate-day schedule
Inhaled corticosteroids
These agents are safer than systemic corticosteroids for long-term anti-inflammatory effect. Dosing is based on the severity of asthma. Some of the most commonly used inhaled corticosteroids in the United States are listed below.
Fluticasone (Flovent HFA, Flovent Diskus)
Fluticasone decreases inflammation by suppressing the migration of polymorphonuclear leukocytes and reversing capillary permeability. Available as aerosol, Flovent HFA (44 mcg/actuation, 110 mcg/actuation, or 220 mcg/actuation), also available as Flovent Powder for Inhalation (Diskus) that delivers 50 mcg/actuation, 100 mcg/actuation, or 250 mcg/actuation.
Adult
Doses may be higher for patient with poor asthma control
HFA:
Previously on bronchodilators alone: 88-132 mcg inhaled PO bid; may increase to 440 mcg bid; higher doses may be necessary
Previously on inhaled corticosteroids: 88-220 mcg inhaled PO bid; may increase to 440 mcg bid or higher
Previously on PO corticosteroids: 440 mcg inhaled PO bid; may increase to 880 mcg bid or higher

HFA; 4-11 years: 88 mcg inhaled PO bid; higher doses may be required
Powder; 4-11 years: 50 mcg inhaled PO bid; may increase to 100 mcg bid or higher
HFA or powder: Adolescents: Administer as in adults
Drugs metabolized by CYP450 3A4 isoenzyme (eg, ketoconazole) might increase fluticasone concentrations
Documented hypersensitivity
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Suppression of HPA, suppression of linear growth, or Cushing syndrome may occur; caution with untreated systemic infections, ocular herpes simplex, or respiratory tuberculosis; rinse mouth after use to reduce likelihood of PO candidiasis; use with spacer
Budesonide (Pulmicort Flexhaler)
Budesonide is relatively new to US market but has been extensively used in Europe. It has recently been released in a nebulizer solution approved for use in children as young as 12 mo.
Budesonide decreases inflammation by suppressing the migration of polymorphonuclear leukocytes and reversing capillary permeability. Available as Pulmicort Flexhaler, powder for inhalation (90 mcg/actuation and 180 mcg/actuation, each actuation delivers 80 mcg/actuation and 160 mcg respectively) or Pulmicort Respules inhalation susp (0.25 mg/2 mL, 0.5 mg/2 mL, or 1 mg/2 mL). Nebulization has been used in children aged 1-8 y.
Adult
Doses may be higher for patient with poor asthma control
Flexhaler: 360 mcg inhaled bid initially; may increase to 720 mcg bid
Pediatric
Doses may be higher for patient with poor asthma control
Flexhaler:
<6 years: Not established
180 mcg inhaled bid initially, for some 360 mcg bid may be appropriate; not to exceed 360 mcg bid
Respules (Age 12 mo to 8 y):
Previously on bronchodilators alone: 0.5 mg/d inhaled via nebulization administered qd or divided bid
Previously on inhaled corticosteroids: 0.5 mg/d inhaled via nebulization administered qd or divided bid; may increase to 1 mg/d
Previously on PO corticosteroids: 1 mg/d inhaled via nebulization administered qd or divided bid
The manufacturer recommends not mixing the Respules with any other nebulized medications, they should be administered as separate treatments; ketoconazole and other inhibitors of CYP450 3A may interfere with budesonide metabolism and increase serum levels; cimetidine caused a slight decrease in budesonide clearance
Documented hypersensitivity
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Suppression of HPA, suppression of linear growth, or Cushing syndrome may occur; caution with untreated systemic infections, ocular herpes simplex, or respiratory tuberculosis; rinse mouth after use to reduce likelihood of PO candidiasis; use with spacer; all clinical studies on the Respules were performed with a mask tightly fitting over the nose and mouth or with a mouthpiece in the mouth; these are the recommended methods of delivery; the "blow-by" technique frequently used for nebulizer medications in children is strongly discouraged; the Respules should not be used in an ultrasonic nebulizer
Beclomethasone
Decreases inflammation by suppressing the migration of polymorphonuclear leukocytes and reversing capillary permeability. Available as 40 mcg/actuation or 80 mcg/actuation.
Adult
Previously on bronchodilators alone: 40-80 mcg inhaled PO bid initially; may increase up to 320 mcg bid; higher doses may be necessary

Coadministration with ketoconazole may increase plasma levels but does not appear to be clinically significant
Documented hypersensitivity
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Suppression of the HPA, suppression of linear growth, or Cushing syndrome may occur; caution with untreated systemic infections, ocular herpes simplex, or respiratory tuberculosis; rinse mouth after use to reduce likelihood of PO candidiasis; use with spacer
Corticosteroid and bronchodilator combinations
These agents elicit long-acting beta2-adrenergic agonistic and anti-inflammatory effects for persistent asthma.
Fluticasone and salmeterol (Advair HFA, Advair Diskus)
Indicated to treat chronic persistent asthma. Salmeterol component elicits long-acting beta2-adrenergic agonist activity, resulting in bronchiole smooth muscle relaxation. Fluticasone is a corticosteroid that provides anti-inflammatory effects.
Available as powder inhalant containing fluticasone (100 mcg, 250 mcg, or 500 mcg) with salmeterol (50 mcg). HFA preparation in metered dose inhalers has 45, 115 or 230 mcg per puff, each with 21 mcg of salmeterol.
Adult
Diskus: 1 inhalation PO q12h; determine dosage strength according to dose of previously administered inhaled corticosteroid
HFA: 2 inhalations PO q12h
Pediatric
Diskus:
<4 years: Not established
4-11 years:
100 mcg/50 mcg inhaled PO q12h
>12 years: Administer as in adults
HFA:
<12 years: Not established
>12 years: Administer as in adults
Drugs metabolized by CYP450 3A4 isoenzyme (eg, ketoconazole) might increase fluticasone concentrations; concomitant use of beta-blockers may decrease bronchodilating, and vasodilating effects of beta agonists such as salmeterol; concurrent administration with methyldopa may increase pressor response; coadministration with oxytocic drugs may result in severe hypotension; ECG changes and hypokalemia resulting from diuretics may worsen when coadministered with salmeterol
Documented hypersensitivity; angina, tachycardia, and cardiac arrhythmias associated with tachycardia
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Not indicated to treat acute asthmatic symptoms; black box FDA warning describes that chronic use may result in increased asthma morbidity and mortality, use only as additional therapy for patients not adequately controlled on other asthma-controller medications (eg, low- to medium-dose inhaled corticosteroids) or patients whose disease severity clearly warrants initiation of treatment with 2 maintenance therapies, including salmeterol
Fluticasone may suppress HPA, suppress linear growth, or cause Cushing syndrome; caution with untreated systemic infections, ocular herpes simplex, or respiratory tuberculosis; rinse mouth after use to reduce likelihood of PO candidiasis
Budesonide and formoterol (Symbicort)
Formoterol relieves bronchospasm by relaxing the smooth muscles of the bronchioles in conditions associated with asthma.
Budesonide is an inhaled corticosteroid that alters level of inflammation in airways by inhibiting multiple types of inflammatory cells and decreasing production of cytokines and other mediators involved in the asthmatic response. Available as MDI in 2 strengths; each actuation delivers formoterol 4.5 mcg with either 80 mcg or 160 mcg.
Adult
Previously on medium-to-high dose inhaled steroids: 2 inhalations of 4.5/160 PO bid
Previously on low-to-medium dose inhaled steroids: 2 inhalations of 4.5/80 PO bid
Not currently receiving inhaled corticosteroids: 2 inhalations PO bid (strength depends on asthma severity)
Do not exceed 2 inhalations of 4.5/160 daily
Pediatric
<12 years: Not established
>12 years: Administer as in adults
Budesonide: None reported
Formoterol: Concomitant use of beta-blockers may decrease bronchodilating, and vasodilating effects of beta agonists; concurrent administration with methyldopa may increase pressor response; coadministration with oxytocic drugs may result in severe hypotension; ECG changes and hypokalemia resulting from diuretics, corticosteroids, or theophylline derivatives may worsen; drugs that widen QTc interval (eg, quinidine, procainamide, pimozide, moxifloxacin, sparfloxacin, gatifloxacin, sotalol, thioridazine, amiodarone) may potentiate cardiovascular side effects; concomitant use with other beta-adrenergic agonists may result in additive effects
Documented hypersensitivity to adrenergic amines, formoterol, budesonide, or any component of formulation; need for acute bronchodilation (including status asthmaticus)
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Use only as adjuvant therapy in patients not adequately controlled on other asthma-controller medications; not meant to relieve acute asthmatic symptoms or rapidly-deteriorating symptoms (treat acute episodes with short-acting beta2 agonist)
caution in patients with cardiovascular disease (arrhythmia or hypertension or HF); beta agonists may cause elevation in blood pressure, heart rate and result in CNS stimulation/excitation and may also increase risk of arrhythmias
Use with caution in patients with diabetes mellitus; beta2 agonists may increase serum glucose; use with caution in patients with GI diseases (diverticulitis, peptic ulcer, ulcerative colitis) due to perforation risk; caution in patients with hepatic impairment and patients with hypokalemia (beta2 agonists may decrease serum potassium); caution in myasthenia gravis (exacerbation of symptoms has occurred during initial treatment with corticosteroids); caution following acute MI (corticosteroids associated with myocardial rupture); caution in patients with cataracts and/or glaucoma; increased intraocular pressure, open-angle glaucoma, and cataracts have occurred with prolonged use; high doses and/or long-term use of corticosteroids have been associated with increased bone loss and osteoporotic fractures;
Renal impairment: Caution in renal impairment (fluid retention may occur); beta agonists may result in CNS stimulation/excitation (caution in patients with seizure disorders); changes in thyroid status may necessitate dosage adjustments; metabolic clearance of corticosteroids increases in hyperthyroid patients and decreases in hypothyroid ones; HPA axis suppression may lead to adrenal crisis (withdrawal and discontinuation of corticosteroids should be done slowly and carefully); particular care required when patients transferred from systemic corticosteroids to inhaled products due to possible adrenal insufficiency or withdrawal from steroids, including increase in allergic symptoms (patients receiving >20 mg/d of prednisone (or equivalent) may be most susceptible); steroids do not provide systemic steroid needed to treat patients having trauma, surgery, or infections; asthma-related deaths
US Boxed Warning: Long-acting beta2-agonists may increase risk of asthma-related deaths; rarely paradoxical bronchospasm may occur with use of inhaled bronchodilating agents (should be distinguished from inadequate response); immediate hypersensitivity reactions (urticaria, angioedema, rash, bronchospasm) reported; prolonged use of corticosteroids may increase incidence of secondary infection, mask acute infection (including fungal infections), prolong or exacerbate viral infections, or limit response to vaccines; exposure to chickenpox should be avoided; corticosteroids should not be used to treat ocular herpes simplex or cerebral malaria; close observation is required in patients with latent tuberculosis and/or tuberculosis reactivity restrict use in active tuberculosis (only in conjunction with antituberculosis treatment); may cause psychiatric manifestations, including depression, euphoria, insomnia, mood swings, and personality changes (pre-existing psychiatric conditions may be exacerbated by corticosteroid use); do not exceed recommended dose (serious adverse events, including fatalities, associated with excessive use of inhaled sympathomimetics
