Respiratory System Disorders Flashcards
(203 cards)
Viral cause of bronchiolitis
Respiratory syncytial virus (RSV), adenovirus, parainfluenza
Part Affected (Laryngo-tracheo Bronchitis)
Subglottic
Medications for bronchiolitis
a. Nebulizer therapy-bronchodilator, corticosteroids and beta agonists
b. Antipyretics(acetaminophen)
c. Mild sedative
d. Antibiotics only if (+) secondary bacterial infection (otitis media)
e. Antiviral therapy
f. RIBAVIRIN (VIRAZOLE)
Diagnosis of croup
- History (fever, cold symptoms, recent viral infection) and clinical manifestations
- X-ray of the neck
- WBC and differential count
→ may go undiagnosed until the child presents with persistent unilateral nasal drainage (if the
neonate develops respiratory infection) and seem to have more nasal obstruction not
proportional to the degree of infection
→ careful questioning reveals an unusual susceptibility to upper respiratory symptoms
unilateral choanal atresia
Disorders of the respiratory system
- Choanal atresia
- Croup
- Bronchiolitis
- Cystic Fibrosis
diagnostic tests in cystic fibrosis: insertion of a hollow needle through abdominal wall into the uterus to obtain cells
from amniotic fluid around the baby. The fluid is then tested to see if both of the baby’s CFTR genes
are normal.
Amniocentesis
less preferred preventive drugs for bronchiolitis
RSV-IGIV
cystic fibrosis is common to what race
caucasians (northern Europe)
high-pitched or squeaking noise when breathing in created by narrowing of the
airway
inspiratory stridor
complications of cystic fibrosis
o Chronic Respiratory infection – pneumonia
o Pneumotho rax
o Chronic respiratory failure
o Cor Pulmonale
o Liver Disease
o DM
o Osteoporosis and arthritis
– loud, harsh, “brassy” or “barking” cough (similar to a the noise of a seal barking)
o the result of swelling around the vocal cords (larynx) and windpipe (trachea). When the cough
reflex forces air through this narrowed passage, the vocal cords vibrate with a barking noise.
croupy cough
diagnostic tests in bronchiolitis: shows hyperaeration and consolidation (similar to that of pneumonia); shows collapse
of alveoli/atelectasis
a. major risk factor for COPD in later life
Chest X-ray
(a drug that stimulates sweating
pilocarpine
A chronic multisystem disorder characterized by exocrine gland dysfunction, inherited as an autosomal
recessive trait
cystic fobrosis
diagnostic tests in cystic fibrosis:
* This test is used to evaluate fat absorption as an indication of how the liver, gallbladder,
pancreas, and intestines work. Normal fat absorption requires bile from the gallbladder (or liver
if the gallbladder has been removed), enzymes from the pancreas, and normal intestines.
* 24 hour stool collection (or sometimes 72 hours or days)
* Consume a normal diet containing about 100 grams of fat per day for 3 days before starting the test;
no substances that interfere with result such as enemas, laxatives, mineral oil
Fecal fat test
How to maintain patent airway in croup
-Assess respiratory status every 2-4 hours or more often as indicated.
-Keep emergency suction and tracheostomy intubation tray at bedside.
-Care of the child in a croupette
-Administer meds as prescribed.
-No to visual inspection of mouth and throat unless when “E” intubation can be done
- .Position head of bed up, not supine.
-.Suction PRN
Medications for bronchiolitis: for high risk infant/child
antiviral therapy
sex affected in cystic fibrosis
male and females are equal
-decreases viscosity of mucus
dornase alfa
diagnosis of choanal atresia:
to determine the exact location of obstruction
Radiography using contrast material
croup is most common at what age
3mos to 5yrs
clinical manifestations of bronchiolitis
o Preceded by URI, manifested as nasal stuffiness, mild fever progressing to increased respiratory
distress (after 1-2 days)
➢ Tachypnea
➢ Nasal flaring
➢ Intercostal and subcostal retractions in inspiration
➢ Dyspnea
➢ Apnea
➢ Mild fever
➢ Tachycardia results from hypoxia
