ESOPHAGEAL ATRESIA (EA) & TRACHEOESPHAGEAL FISTULA (TEF)
Esophageal Atresia (EA): A congenital condition where the esophagus does not fully develop; it may end in
a blind pouch and not connect to the stomach.
Tracheoesophageal Fistula (TEF): An abnormal connection between the esophagus and trachea.
Types (most common to rare):





Type C: EA with distal TEF (most common)
Type A: Isolated EA (no TEF)
Type B: EA with proximal TEF
Type D: EA with both proximal and distal TEF
Type E (H-type): TEF without EA
CAUSES/HISTORY:
Exact cause is unknown, but likely due to abnormal development of the foregut during early fetal
development (25–35 days gestation).

CROUP SYNDROME
Croup (Acute Laryngotracheobronchitis) is a
common respiratory illness in young children, especially
ages 6 months to 3 years. It causes swelling in the upper
airway (larynx and trachea), leading to a barking cough,
hoarseness, and stridor (noisy breathing).
 More common in boys (1.4:1 ratio)
 Peaks in late fall to early winter
 Usually mild and self-limiting, but can become
severe.
Types based on severity:

Mild: Barking cough, no stridor at rest


Moderate: Stridor at rest, chest retractions, difficulty breathing
Severe: Constant stridor, severe distress, cyanosis, fatigue
CAUSES/HISTORY:
Croup is viral in origin. Common viruses include:





Parainfluenza virus types 1, 2, and 3 (most common)
RSV (Respiratory Syncytial Virus)
Influenza A and B
Adenovirus, Rhinovirus
Measles virus (especially in unvaccinated children)
The virus infects the lining of the upper airway, causing inflammation, swelling, and narrowing of the airway—
especially below the vocal cords (subglottic area).
SIGNS AND SYMPTOMS (S/S):
1.
2.
3.
Runny/stuffy nose (coryza)
Low-grade fever
Hoarseness
Progressive Symptoms:
4.
5.
6.
7.
Barking cough (seal-like)
Stridor (noisy breathing)
Respiratory distress (nasal flaring, chest retractions, tracheal tugging)
Worse at night or when crying
Severe Signs (Impending Respiratory Failure):
8.
9.
10.
11.
Cyanosis even with oxygen
Fatigue, lethargy
Decreased/absent breath sounds
Altered mental status
PATHOPHYSIOLOGY:
Virus → immune response → swelling → airway narrows → turbulent airflow = stridor
Severity depends on how narrow the subglottic airway becomes.
NURSING INTERVENTIONS:








Keep child calm and quiet (crying worsens symptoms)
Elevate head to ease breathing
Use cool mist/humidified air (comfort measure)
Monitor breathing: look for stridor, retractions, color
Encourage fluid intake if possible
Educate parents on signs of worsening symptoms
In hospital: oxygen therapy, monitor for rebound after treatment
Rare cases may need intubation or ICU care
MEDICATION/ TREATMENT:

Dexamethasone (steroid):
 Reduces airway swelling
 Dose: 0.15–0.6 mg/kg (oral, IM, or IV)
 Works within hours, lasts 2–3 days



Nebulized Epinephrine (Adrenaline):
 Fast relief from airway swelling
 Short-acting (~2 hours), monitor after use for rebound stridor
Hospitalization if symptoms are severe or not improving
No antibiotics (unless there's a secondary bacterial infection)
ACUTE RESPIRATORY DISTRESS SYNDROME
ARDS is a serious condition where fluid builds up
in the air sacs (alveoli) of the lungs due to
inflammation, making it hard for oxygen to reach the
blood. It is not caused by heart problems, but by
injury or inflammation in the lungs. It can cause low
oxygen (hypoxia), damage to organs, and can be lifethreatening.
Stages of ARDS:
1.
2.
3.
Exudative Phase (1st 24 hours) – Lungs get inflamed, leaky, and stiff; fluid builds up, oxygen exchange is
reduced.
Proliferative Phase (up to 14 days) – Body tries to repair; cells grow back, but scarring may begin.
Fibrotic Phase (after 3 weeks) – Permanent scarring may happen, causing long-term lung problems. Not all
patients reach this stage.
CAUSES/HISTORY:


Direct Lung Injury (Direct causes):
 Pneumonia – Infection causes inflammation and fluid in lungs
 Pancreatitis – Inflammatory chemicals reach lungs
 Aspiration – Inhaling vomit or food causes damage
 Drowning – Water directly fills lungs
 Smoke inhalation – Burns and damages lung tissue
Indirect Lung Injury (Indirect causes):
 Sepsis (most common in adults) – Body’s extreme response to infection
 Severe trauma or burns – Body releases inflammatory signals
 Head injury – Can trigger inflammation
 Blood transfusion reaction – Immune system attacks lungs
 Lung transplant complications – Rejection or injury
 Viral infection (most common in children/PARDS) – e.g., RSV
SIGNS AND SYMPTOMS (S/S):

Hypoxemia (low blood oxygen) – Hallmark sign
Shortness of breath (dyspnea)
Fast, shallow breathing
Fatigue and muscle weakness
Low blood pressure
Dry cough
Fever
Fast heart rate (tachycardia)
Confusion or mental changes
Headache
NURSING INTERVENTIONS:
Main Goals: Improve oxygenation, prevent further injury, and treat the cause.

PEEP (Positive End-Expiratory Pressure):
Keeps alveoli open, improves oxygen levels, prevents collapse
(10–20 cm H₂O depending on patient’s condition)





Administer Oxygen:
 Nasal cannula
 High-flow oxygen
 Mechanical ventilation if needed
Prone Positioning:
 Lying face down improves oxygenation without increasing O₂ level
 Helps air reach more lung areas
Monitor Respiratory Status:
 Look for signs of worsening breathing
 Monitor ABGs (arterial blood gases), oxygen saturation
Fluid Monitoring:
 Avoid fluid overload especially in children
 Check daily weight, I&O (intake and output)
Provide Supportive Care:
 Elevate head of bed
 Suction secretions if needed
 Calm environment to reduce oxygen demand
MEDICATION/ TREATMENT:





Oxygen therapy – to treat low oxygen
Antibiotics – for bacterial infection
Corticosteroids – reduce inflammation
Sedation or paralytics – may be used with ventilator support
Treat underlying cause – sepsis, trauma, infection, etc.
ASTHMA
Asthma is a long-term (chronic) disease where the
airways in the lungs become swollen and narrow. This
makes breathing hard. It causes coughing, wheezing, chest
tightness, and shortness of breath.
It is an allergic reaction (Type 1 hypersensitivity)
and can happen at any age—most common in children.
Types of Asthma:




Intermittent: Happens <2 days/week; no daily limits; rare at night.
Mild Persistent: >2 days/week but not daily; affects activity a little.
Moderate Persistent: Daily symptoms; needs daily meds; night attacks weekly.
Severe Persistent: All-day symptoms; limits activities; frequent nighttime attacks.
CAUSES/HISTORY:
Asthma often runs in families, showing it's inherited. Allergies are the main cause.
Common triggers:




Pollen, dust, mold, smoke, pet dander
Cold air, stress, infections
Exercise or certain foods
Jobs with chemical exposure (occupational asthma)

CYSTIC FIBROSIS
Cystic Fibrosis (CF) is a serious inherited
(genetic) disorder that affects the exocrine glands.
These glands produce mucus, sweat, and digestive
juices. In CF, these secretions become thick and
sticky, causing blockages in the lungs, pancreas,
intestines, and other organs.
CAUSES/HISTORY:




CF is an autosomal recessive disorder caused by a defect in the CFTR gene (located on chromosome 7).
This gene controls how salt and water move in and out of cells.
The faulty CFTR protein leads to thickened secretions that clog organs like the lungs and pancreas.
CF is more common in Northern-European Caucasian children and rare in Black or Asian children.
1 in 2,500 live births are affected.
SIGNS AND SYMPTOMS (S/S):
1. Pancreas Involvement
Blocked pancreatic ducts prevent digestive enzymes from reaching the intestines.
Results in:





Steatorrhea (large, greasy, foul-smelling stools)
Malnutrition (thin limbs, bloated belly)
Vitamin A, D, E, K deficiencies
Meconium ileus in newborns (early intestinal blockage)
Rectal prolapse (due to frequent straining)
2. Lung Involvement
Thick mucus clogs airways leading to:





Chronic lung infections (with bacteria like Staph aureus, Pseudomonas, H. influenzae)
Bronchiectasis and pneumonia
Secondary emphysema, atelectasis, respiratory acidosis
Clubbing of fingers
Barrel-shaped chest
3. Sweat Glands


Excess salt is lost through sweat.
Parents may notice salty skin when kissing their baby.
COMPLICATIONS:
Infertility:


Males: blocked vas deferens
Females: thick cervical mucus (hard for sperm to pass)
Fertility may be possible with IVF or artificial insemination
DIAGNOSTIC TESTS:
