|
The reactive portion of hte lower respiratory tract includes?
|
bronchi
bronchioles |
|
|
Cartilaginous support of the large airways are not fully developed until?
smooth muscle in these structures represents a major factor in the constriction or the airway particularly in the bronchioles |
adolescence...how does this affect childrens' airways?
|
|
|
Define bronchitis (tracheobronchitis)?
|
inflammation of large airways (trachea and bronchi) which is frequently associated with URI...usually viral
|
|
|
What is the primary cause of bronchitis?
|
viral agents...
however, Mycoplasma pneumoniae is a common cause in children older than 6 years of age... other non-viral agents causing bronchitis include: bacteria fungi allergic disorders airborne irritants smoking |
|
|
What are the symptoms of bronchitis?
|
dry, hacking, nonproductive cough that worsens at night and becomes productive in 2 to 3 days
|
|
|
Is bronchitis severe?
|
no...it's a mild and self-limiting disease requiring only symmptomatic treatment
|
|
|
What treatment is needed for bronchitis?
|
basically palliative (make it more comfortable)
analgesics antipyretics hummidity cough suppressants may be useful to allow rest but can interfere with clearance of secretions.. takes about 5-10 days to recover rest bronchodilators increase fluid intake (encourage about 2-3 Liters per day unless contraindi- cated)...helps to liquify secretions and make it easier to expectorate secretions) humidify air an antitussive might be given to give relief from coughing, but be careful not to give them so much they can't expectorate the secretions...contain codeine (Robitussin A-C, Dimetane D-C) and may cause drowsiness antihistamines will open passageways which reduce salivary, lacrimal, bronchial and gastric and bronchial secretions decongestants stimulate swollen blood vessels and the sinuses constrict....this causes the inflammation to go down and opens up the airways the expectorants thin the secretions whether they can be coughed up Guaifenesin (Robitussin) is used more often for expectorant; however it can irritate the GI tract |
|
|
What is codeine (Robitussin A-C)?
|
opioid antitussive agent
used in combination with many other common cough and cold meds for treatment of coughs potentially addictive can depress respirations and CNS contraindicated with respiratory depression and increased intracranial pressure, seizure disorders and severe respiratory disorders onset 30-60 min peak 1-2 hr duration 4-6 hr |
|
|
What is guaifenesin (Robitussin)?
|
expectorant for management of coughs...thins difficult- to-cough up mucus in productive coughs
use with caution in individuals with asthma or respiratory insufficiency |
