Pediatric Respiratory Diseases

Most Common Pediatric Respiratory Diseases


Cystic Fibrosis

  • Cystic fibrosis is a chronic multisystem Disorder in which is characterized the Dysfunction of exocrine gland.
  • Cystic fibrosis is an autosomal recessive Disorder
  • That affects epithelial cells of the respiratory, gastrointestinal, reproductive , integumentary system and leads to abnormal exocrine gland se oration.
  • Exocrine gland secretes the – mucus, sweat, juices.
  • Mucus produced by Exocrine gland is abnormally thick causing obstruction of small passage of any system.
  • Increase sodium and chloride in sweat and saliva is the best Diagnostic test of cystic fibrosis.


Etiology of Cystic fibrosis

  • Mutation in the cystic   fibrosis gene on 7th chromosome
  • Abnormal CFTR protein (Cystic fibrosis transmembrane regulator)
  • Defective chloride transportation
  • Excessive mucus production
  • Infection, Atelectasis, Bronchiectasis
  • Dilation of Distal airway
  • Chronic hypoxemia
  • An abnormal elevation of sodium and chloride

Most common features of cystic fibrosis

  • Pancreatic enzyme Deficiency caused by blockage of Duet
  • Chronic progressive lung Disease Due to repetitive inflection
  • Dysfunction of sweat gland, due to Increase Na+ and Cl– 

Clinical Manifestations of Cystic fibrosis

  1. effect of cystic fibrosis on the respiratory system

  • Productive cough and wheezing
  • Excessive thick mucus production
  • Obstruction of the respiratory tract due to thick mucus

  • Barrel chest shape
  • High resonance sound in lungs
  • Dyspnea and cyanosis
  • Chronic bronchitis
  1. effect of cystic fibrosis on GI system

  • The earliest manifestation is = meconium ileus in a neonate
  • Intestinal obstruction – due to thick intestinal secretion
  • Nausea , vomiting , abdominal pain and distension
  • Malnutrition
  • Diabetes mellitus due to fibrosis
  • Acute pancreatitis
  • Steatorrhea
  • Failure of thrive and rectal prolapsed
  • Stool are frothy and foul smelling
  • Hypoalbumia
  1. effect of cystic fibrosis on the Reproductive system

  • Delay puberty in girls
  • Reduce fertility chance in females
  • In male, High chance of infertility
  1. effect of cystic fibrosis on the Integumentary system

  • Salty test on kiss the child
  • High concentration of sodium and chloride in sweat
  • Dehydration due to excessive water loss by sweat
  • Electrolyte Imbalance

Diagnosis test for cystic fibrosis

  1. Sweat chloride test –

these tests require the sweat

  • Provide the pilocarpine drug for production the of sweat
  • Collect the sweat of more than 75mg
  • Normal sweat chloride concentration is less than 40meq/liter (40mmol/L)
  • If sweat chloride concentration is more than 60meq/L, indicates cystic fibrous is present
  • Child less than 6 months –  >60meq/L – Positive

– <30meq/L – Negative

  • Child more than 6month – >60meq/L  = Positive

– <40meq/L = Negative

  1. Chest X-ray – for emphysema and atelectasis
  2. Pulmonary function test
  3. Trypsin and chymotrypsin estimation test in stool
  4. Genetic test and sputum culture test

management of cystic fibrosis

  • Airway clearance is the 1st intervention
  • Provide chest physiotherapy to remove the Excessive mucus from the respiratory tract.
  • Chest physiotherapy produces the vibration on the lungs segment and drainage out of mucus.

  • But Hemoptysis is present use cough suppressant
  • Last treatment of cystic fibrosis in respiratory tract is – lungs transplant
  • Provide the high calorie , high protein , and well balance diet
  • Monitor weight and for failure to thrive
  • Provide the pancreatic enzyme supplement to maintain the normal mechanism of digestion
  • Administer of pancreatic enzyme , with meal before 30mint of food
  • Provide supplement of vitamin  A,D,E,K
  • Avoid the pancreatic enzyme when patient on NPO.
  • Monitor the stool pattern and for sign of intestinal obstruction

Bronchiolitis in Children

  • Bronchiolitis is an acute infectious inflammatory disease of the upper respiratory tract and lower respiratory tract that result in obstruction of the small airways.
  • Bronchiolitis is inflammation of the Bronchioles that causes the production of thick mucus that block the bronchioles and bronchi.
  • RSV (Respiratory syncytial virus) is a most common cause of Bronchiolitis.
  • RSV is not an airborne infection, it is highly communicate by contaminated hand.

Foreign body Aspiration in children

  • Foreign body aspiration of a foreign body into the air passes.
  • Foreign body aspiration commonly occurs in the infant and toddler.
  • Most inhaled foreign body settle down in the main stem or lobar bronchus.
  • Large Foreign body aspiration is obstructed the upper airway and cause immediate features.
  • Small foreign body aspiration is obstructed the Respiratory tract for long time and cause the chronic effects.

Incidence of Foreign body aspiration

  • Commonly 1-3 years age group affected.
  • Sex – Male more prominent

Visual foreign bodies are

  1. Organic – Peanuts, Popcorn, Seeds, Hotdogs, Vegetable matter
  2. Inorganic -Toys part, pen tops, tracks, pins, nails, Screw, and bullet and casing

Composition of foreign body

  1. Large foreign body produce clinical feature immediately within 3-5 minutes.
  2. Small foreign body id deposit in secondary bronchus and produce aspiration pneumonia.
  3. Buttons, pins, small parts of toy can cause the irritation and edema in the Respiratory tract.

Anatomical location of Obstruction Foreign body aspiration

  1. Foreign body commonly obstruction the trachea and larynx.
  2. Bronchus is most common site of obstruction, mainly right bronchus have more chances because right bronchus is more horizontal and wide.

Degree of obstruction in Foreign body aspiration

  1. Foreign body aspiration creates the obstruction in inspiration and expiration.
  2. A large foreign body only obstructs the expiration.
  3. Small foreign body do not interfere in inspiration and expiration.

Clinical feature of Foreign body aspiration

The clinical feature of foreign body aspiration depends upon the anatomical location of the obstruction.

Foreign body Obstruction at Larynx

Wheezing sound during expiration

      • Harness of voice
      • Inability to speak
      • Coughing
      • Hemoptysis
      • Dyspnea

Foreign body aspiration Late sign 

  • Wheezing
  • Emphysema
  • Atelactesis.

Diagnosis of Foreign body aspiration

  • History collection and physical examination.
  • X-ray (Anterior, posterior and lateral)
  • Bronchoscopy – To diagnose tracheal obstruction.
  • Laryngoscope use to find out the obstruction.
  • Laryngoscope also use in removal of obstruction.
  • Fluoroscopic Examination

Management of Foreign body aspiration

  • Early removal of foreign bodies reduces the chance of inflammation and edema.
  • Below 1-year child – 5 back slaps and 5 Chest thrusts apply
  • In children, fingers are never inserted to remove foreign bodies because of chance of deep aspiration.
  • In adults, foreign body remove by Meinlich Maneuver ( abdominal thrush maneuver)
  • The child does not produce P sound means obstruction is severe
  • Antibiotics and steroids provide for the treatment of inflammation
  • Humidified air should be inhaled after the removal of a foreign body.
  • Treat the foreign body aspiration complication.

Nursing management of foreign body aspiration

  • Nurse all the small objects should be away from the child
  • Any person and nurse not set a example by putting any object in the mouth in front of child.
  • After ingestion the object, Nurse allows a comfortable position.
  • Nurse never attempt to allowing figure to remove the object.
  • Nurse Dont need to play with small toys and vegetables, nuts, etc.
  • Nurse encourage to mother for avoiding the laugh the child during feeding.
  • Nurse educate the mother never feed child during he is play and running

KEY POINTS Foreign body aspiration

  • Foreign body aspiration occur which age group children – Infant and toddler.
  • Which type foreign body aspiration create the aspiratory pneumonia – Small foreign body.
  • Foreign body commonly obstructed into the –Trachea and Larynx.
  • Most common site of foreign body obstruction in the bronchus –Right bronchus.
  • Large foreign body obstruction is interferer in – Expiration.
  • Audiable slap and palpate thud sounds are occur in the – Tracheal Obstruction
  • Most common management of foreign body removal in 1 Year children – Give 5 back below between the shoulder.
