Key Pediatric Key Pediatric Differences in the Differences in the

Respiratory SystemRespiratory System• Lack of or insufficient surfactant (premature

infant) • Smaller airways and underdeveloped cartilage• Tonsilar tissue enlarged• More flexible larynx• Obligatory nose breather (infant)• Less well developed intercostal muscles• Brief periods of apnea common (newborn)• Faster respiratory rate• Increased metabolic needs• Eustachian tubes relatively horizontal

Respiratory Diseases and Respiratory Diseases and Disorders of ChildhoodDisorders of Childhood

• Otitis Media• Pharyngitis• Epiglotitis• Broncholitis• Pneumonia• Asthma exacerbation• Cystic Fibrosis• Tuberculosis

Upper Upper Respiratory Respiratory

Tract Tract DisordersDisorders

Otitis Media (OM)Otitis Media (OM)• One of the most common illnesses in infancy and

childhood• Peak incidence: 6 months to 6 years• Infection or blockage of the middle ear• Acute, Chronic or Serous OM

Risks for Development Risks for Development of Acute Otitis Mediaof Acute Otitis Media

• Exposure to second hand smoke• Allergies• Bottle fed infants

(AOM) Acute Otitis (AOM) Acute Otitis MediaMedia

• Sudden temperature increases

• Sharp pain • Otalgia (earache); pull

on ear, rubbing face • Irritability• Sleep disturbance• Persistent crying• Fever, vomiting,

diarrhea, anorexia• Sudden relief and

drainage=rupture TM

TreatmentTreatment• AOM could be viral or bacterial• Acetaminophen (pain, fever)• Amoxicillin for 7-10 days if bacterial• ALTERNATIVE- wait 72 hours then treat

Serous Otitis Media or Serous Otitis Media or

Otitis Media with Effusion Otitis Media with Effusion

(SOM/OME)(SOM/OME)• Result of chronic otitis

media (3 AOM in 6 months or 4 AOM in 1 year)

• Epithelial cells of middle ear begin producing secretions instead of absorbing them

Surgical Surgical InterventionsInterventions

Myringotomy• Surgical incision or laser of the tympanic membrane• Allows mucoid material to be removed from middle

earTympanostomy tubes• Placed to equalize pressure on both sides of the

tympanic membrane, keeps ear aerated• Allows middle ear mucosa to return to normal and

growth of the eustachian tube to continue

Patient Teaching-Patient Teaching-Post OpPost Op

• Monitor for ear drainage

• Report any fever or increased pain

• Avoid blowing nose for 7-10 days

• Swimming, showers allowed only with earplugs

• Diving and swimming in deep water is prohibited

Pharyngitis (Tonsillitis)Pharyngitis (Tonsillitis)

of pharynx and tonsils (may be slight)

• Vesicles or ulcers on tonsils

• Fever (usually low grade)

• Hoarseness, cough, rhinitis, conjunctivitis, malaise, anorexia

• Cervical lymph nodes may be enlarged, tender

• Usually lasts 3-4 days then resolves spontaneously

Bacterial Pharyngitis Bacterial Pharyngitis • Abrupt onset (may be

gradual in children younger than 2 years)

• Sore throat (usually severe)

• Erythema, inflammation of pharynx and tonsils

• Fever usually high (103-104F) but may be moderate

• Abdominal pain, headache, vomiting

• Cervical lymph nodes may be enlarged, tender

o coughing frequentlyo clearing the throato blowing the nose

CroupCroup

Manifestations of Manifestations of CroupCroup

• Begins at night; may be preceded by several days of symptoms of upper respiratory tract infection

• Sudden onset of harsh, barky cough; sore throat; inspiratory stridor; hoarseness

• Could progress into use of accessory muscles to breathe

• Frightened appearance; agitation• Cyanosis

• Mostly viral in nature, resolves spontaneously

• Humidification and cold air resolves attacks

EpiglottitisEpiglottitis• Bacterial form of croup (H influenza) with unique

symptoms and treatment• Bacterial infection invades tissues surrounding the

epiglottis• Epiglottis becomes edematous, cherry red and may

completed obstruct airway• Progresses rapidly, child is unable to swallow,

drooling

SymptomsSymptoms

• May have had mild URI few days prior• Drooling• Dysphasia • Dysphonia • Distressed respiratory efforts• Tripod position: supported by arms, chin

thrust out, mouth open

ER ManagementER Management• NEVER leave child unattended• Don’t examine or culture throat or start IV/Blood

samples• Continuous pulse ox • Humidified O2• Antipyretics suppository-nothing PO• Calm the parent! Explain what is going on…a calm

parent=calmer child!• OR- intubation• Throat & blood cultures done after intubation• Usually extubated after 48h• Antibiotics for 7-10 days• Discharge

Nursing Interventions on Nursing Interventions on

Chronic Lung Chronic Lung DiseasesDiseases

AsthmaAsthma• A reversible obstructive

airway disease

• Hypersensitivity of many cells (Mast, Eosinophils, T Lymphocytes)

• Increased airway responsiveness to a variety of stimuli

AsthmaAsthma• Bronchospasm resulting from constriction of bronchial

smooth muscle

• Inflammation and edema of the mucous membranes that line the small airways and the subsequent accumulation of thick secretions in the airways

• Initial Symptom is a Cough (w/o illness) usually at night• Wheezing is produced when there is decreased

expiratory airflow

Asthma SeverityAsthma Severity• Classified as

o Mild intermittent• Symptoms < 2 x week

o Mild Persistent• Symptoms > 2 x week, but less than

once a dayo Moderate

• Day symptoms 2 x week, 1 or more night symptoms per week

o Severe• Continual day symptoms, frequent

night symptoms

use and storage, nebulizer)

Teach use of Peak Flow Teach use of Peak Flow MeterMeter

• Measures maximum peak expiratory flow rate

• Need to first use when healthy to mark baseline

• Can use to predict acute exacerbation in kids 5-6 years and older

• Take a deep breath, blow out hard and fast

• If peak flow is 30-50% of child’s predicted baseline=ER

Cystic Fibrosis (CF)Cystic Fibrosis (CF)• Mutated gene on chromosome 7 CFTR

• Inherited autosomal recessive trait

• Both parents carry gene

(1/4 chance of conceiving affected child)

Cystic FibrosisCystic Fibrosis• Chronic multisystem disorder affecting the exocrine

glands• Affects bronchioles, small intestines, pancreatic &

bile ducts• Usually diagnosed before 1st birthday• Incurable• Symptoms worsen as disease progresses• Median life expectancy is reduced due to infections

Cystic FibrosisCystic Fibrosis• Respiratory System• Gastrointestinal System• Reproductive System• Exocrine Glands

Respiratory SystemRespiratory System• Wheezing, dry, non-productive cough,

repeated URI’s• Copious, thick sputum• Crackles, wheezes, decreased breath sounds• Increasing signs of respiratory distress =>

emphysema & atelectesis• Clubbing, barrel chest

Nursing ManagementNursing Management• Facilitate airway clearance • Prevent pooling of secretions – postural drainage• CPT every 4 hours (1 hour before or 2 hours after meals,

prior to bedtime)• Forced expiration (“huffing”)• Prevention and treatment of pulmonary infections-

aggressive IV antibiotics• Administer bronchodilators and mucolytics • High-humidity cool-mist tent to mobilize secretions• If 02 is required, use low flow rate

CPTCPT

Gastrointestional Gastrointestional SystemSystem

• Steatorrhea: frothy, foul-smelling stools 2-3 times bulkier than normal

• Malnutrition and failure to thrive despite normal caloric intake

• Protuberant abdomen• Fat soluble vitamin deficiencies: K, A, D, E (caused

by inability to absorb fats)• Meconium illeus in the newborn might be 1st sign

Nursing ManagementNursing Management• Well balanced diet high in calories,

protein, carbohydrates• Pancreatic enzymes within 30 minutes of

eating all meals and snacks

Reproductive Reproductive SystemSystem

• Average of 2 year delay in the development of secondary sex characteristics

• Females have thick cervical mucus (trouble getting pregnant)

• Some male patients sterile due to lack of sperm

Exocrine GlandsExocrine Glands

• Abnormally high concentrations of sodium and chloride in the sweat

• Sweat Test determines amount of sodium chloride in sweat

• Risk for electrolyte imbalance during hot weather

Nursing Nursing ManagementManagement

• Monitor for dehydration• Extra salt and fluid in hot weather

Dehydration Dehydration and Fluid Lossand Fluid Loss

Dehydration and Fluid Dehydration and Fluid LossLoss

• Large portion of a child’s fluids is located in extracellular fluid (increased BSA)o Infants: 75-80% of the weighto 2 year old: 60% of weight

• First two years of life kidneys are not functionally mature

• Inefficient at excreting waste products

Dehydration and Fluid Dehydration and Fluid LossLoss

• Fluid and electrolyte imbalances develop and progress very quickly

• Sick children often have low PO intake and diarrhea and vomiting =

• Infants and young children are highly susceptible to rapid and profound fluid and electrolyte imbalances

Types of Fluid LossTypes of Fluid Loss

• Sensible Fluid Loss• Insensible Fluid Loss

Sensible Fluid LossSensible Fluid Loss• Can be measured and observed• Urine output• Drains and tubes• Emesis • Diarrhea

Insensible Fluid LossInsensible Fluid Loss• Loss of fluid through lungs (2/3) and skin

(1/3)• Influenced by heat and humidity, body

temp, respiratory rate (children have higher RR than adults)

• Basal metabolic rate increases 10% for each degree Celsius above normal body temperature

• Example 39 Celsius = 102.2F o BMR increases by 20% !

ElectrolytesElectrolytes• NA- major electrolyte in ECF

o Needed to establish osmolarity

• K- major electrolyte in ICFo Needed for excitability of neurons and muscles

Three Types of Three Types of DehydrationDehydration

• Isotonic• Hypotonic• Hypertonic

Isotonic DehydrationIsotonic Dehydration• Sodium and water deficits are the same

(salt and water are lost in equal amounts in ICF and ECF)

• NA+ 130-150meq/L (normal)• Most common type in children from low PO

intake• Can result in hypovolemic shock

Hypotonic Hypotonic DehydrationDehydration

• Sodium deficit is greater than the water deficit

• Water moves from ECF to ICF• NA+ < 130meq/L• Results from GI losses (vomit, diarrhea)

• May result in shock

Hypertonic Hypertonic DehydrationDehydration

• Water loss exceeds sodium loss• Body compensates with fluid shifts from ICF

to ECF• NA+ > 150meq/L• May be caused by severe vomiting, too

much IV NA• Can result in seizures

Know the S+S of Know the S+S of DehydrationDehydration

• MildoNormal VS, moist mucous membranes,

alert, normal urine output, normal turgor, fontanelle, normal cap refill, thirsty

• Moderateo Rapid pulse and RR, normal BP, dry

mucous membranes, irritable, dark urine and decreased output, poor turgor, sunken fontanelle, delayed cap refill, moderately thirsty

Know the S+S of Know the S+S of DehydrationDehydration

• Severe• Changes in respirations depth and pattern, rapid weak pulse, low BP, mucous membranes parched, can be comatose, absent urine output, very poor turgor, sunken fontanelle, cool skin

Monitor for Monitor for DehydrationDehydration

URINE OUTPUT SHOULD BE AT MINIMUM1 ml/kg/hr

ALL children are on I+O

Monitor labs for:o Increased BUNo Increased serum bicarboHyponatermiaoHyperkalemiao Increased urine specific gravity

PREVENT dehydrationPREVENT dehydration• Monitor temperature, prevent overheating• Give frequent fluids, may need oral rehydration

(pedialyte) 50 ml/kg/ in 4 hours when febrile and GI losses

• Use small medicine cups, syringe without needed to administer fluids…even 1 tsp every few minutes

• Monitor IV fluid administration, ensure patent IV site

Administering IV Administering IV FluidsFluids

• Always use an infusion pump with a volume control device

• Prevents a sudden extracellular fluid volume overload

• Never use more than a 500 ml bag

• Mechanical pumps can have faulty performance, so check the intravenous line, bag, and rate often
