Transcript Specific Medical Emergencies
A
variety of pediatric medical problems can
activate the EMS system
The majority of childhood medical
emergencies involve the respiratory system
Other systems may be involved
Infectious
diseases may be caused by the
infection or infestation of the body by an
infectious agent
Virus, bacterium, fungus, or parasite
Most
infections are self-limiting
Some infections may be life threatening
Meningitis, pneumonia, and septicemia
Fever
Chills
Tachycardia
Cough
Sore throat
Nasal congestion
Malaise
Tachypnea
Cool or clammy skin
Petechiae
Respiratory distress
Poor appetite
Vomiting
Diarrhea
Dehydration
Hypoperfusion
Purpura
Seizures
Severe headache
Irritability
Stiff neck
Bulging fontanelle
Take
all Standard Precautions
Become familiar with the common pediatric
infections encountered in your area
Previous exposure to disease and
vaccinations
The
most common reason EMS is summoned
to care for a pediatric patient
Your approach to the child with a respiratory
emergency will depend on the severity of
respiratory compromise
Three
categories
Respiratory distress
Respiratory failure
Respiratory arrest
Learn
in
to recognize the phase your patient is
Mildest
form of respiratory impairment
Increased work of breathing
Increase in respiratory rate
Frequently estimated
Should be measured for at least 30 seconds
Normal
mental
status deteriorating
to irritability or
anxiety
Tachypnea
Retractions
Nasal flaring (in
infants)
Poor
muscle tone
Tachycardia
Head bobbing
Grunting
Cyanosis that
improves with
supplemental oxygen
Occurs
when the respiratory system is not
able to meet the demands of the body for
oxygen intake and for carbon dioxide
removal
Characterized by inadequate ventilation and
oxygenation
Irritability
or anxiety
deteriorating to
lethargy
Marked tachypnea
later deteriorating
to bradypnea
Marked retractions
later deteriorating
to agonal
respirations
Poor
muscle tone
Marked tachycardia
later deteriorating
to bradycardia
Central cyanosis
The
end result of respiratory impairment
The cessation of breathing
Typically follows a period of bradypnea and
agonal respirations
Unresponsivenes
deteriorating to coma
Bradypnea deteriorating to apnea
Absent chest wall motion
Bradycardia deteriorating to asystole
Profound cyanosis
Should
be based on the severity of the
problem
Goals of management
Increasing ventilation
Increasing oxygenation
Airway
Patency
Assure continued maintenance of the airway
Breathing
Administer high-flow, high-concentration oxygen
If no improvement the patient should be treated
more aggressively
Treatment
of late respiratory failure or
arrest
Mechanical ventilation with a BVM device
Endotracheal intubation
Consideration of gastric decompression
Consideration of needle decompression
If suspected pneumothorax
Consideration of cricothyrotomy
Circulation
You should obtain venous access
Transport
to an appropriate facility
Continue to reassess the child
Provide emotional and psychological support
Upper
airway distress
Croup
Epiglottitis
Bacterial Tracheitis
Foreign Body Aspiration
Viral
infection of
upper airway
Occurs in children 6
months to 4 years of
age
Leads to edema
beneath the glottis
and larynx
Assessment
Child will have a mild cold or other infection
Develops loud, brassy cough at night
You should never examine the oropharynx
Difficult to distinguish from epiglottitis
Management
Position of comfort
Cool, mist oxygen
Administration of racemic epinephrine or
albuterol may be considered
An
acute infection and
inflammation of the
epiglottis
Caused by a bacterial
infection
Haemophilus
influenzae type B
Tends
to strike
children 3–7 years old
Assessment
Child awakens with a high temperature and a
brassy cough
Pain upon swallowing, sore throat, high fever, shallow
breathing, dyspnea, inspiratory stridor, and drooling
Never attempt to visualize airway
Patients will often assume the “tripod position”
Management
Appropriate airway
maintenance and
oxygen administration
If the airway becomes
obstructed:
Two-rescuer ventilation
with BVM is almost
always effective

Management
Intubation equipment is available
(cont.)
Contraindicated unless obstruction occurs
Immediate transport
Handle gently
Do not visualize airway
Avoid IV sticks
Bacterial
infection of the airway, subglottic
region
Afflicts mainly infants and toddlers 1–5 years May
follow episode of croup
Assessment
Presence of a high-grade fever accompanied by
coughing up of pus and/or mucous
Hoarse voice
Inspiratory or expiratory stridor
Management
Manage airway and breathing
Ventilations may require high pressure
Oxygen by mask or blow-by
Depress pop-off valve on BVM
Consider intubation only in cases of complete
airway obstruction
The
number one cause of in-home accidental
deaths in children under 6 years
Food or foreign objects
Assessment
Partial
Complete
Management
If the obstruction is partial:
Make the child as comfortable as possible and
administer humidified oxygen
Have intubation equipment available
Transport
If complete:
Utilize basic life support techniques
Visualize the airway with a laryngoscope
Lower
Airway Distress
Asthma
Bronchiolitis
Pneumonia
Foreign Body Lower Airway Obstruction
Chronic
inflammatory disorder of the lower
respiratory tract
Pathophysiology
Characterized by bronchospasm and excessive
mucous production
Widespread, but variable, airflow obstruction
The airways become hyperresponsive
Pathophysiology
(cont.)
“Triggers”
Two-phase reaction occurs
Release of chemical mediators such as histamine
Bronchoconstriction
Responds to bronchodilator medications
Inflammation of the bronchioles as cells of the immune
system invade the respiratory tract
Additional edema and further decreases in expiratory
airflow
Assessment
Can often be differentiated from other pediatric
respiratory illnesses by history
Medications may also be an indicator
Usually sitting up, leaning forward, and
tachypneic
Wheezing may be heard
An ominous finding is lack of wheezing
Management
Establish an airway
Supplemental,
humidified oxygen
Pharmacological
interventions
Inhaled beta agonist
Nebulized
bronchodilator
medications
Steroid administration
© Ken Kerr
Status
Asthmaticus
Severe, prolonged asthma attack that cannot be
broken by aggressive pharmacological
management
Child will have greatly distended chest
Patient is usually exhausted, severely acidotic,
and often dehydrated
Prepare for intubation
Respiratory
infection of the medium-sized
airways
Caused by a viral infection
Respiratory syncytial virus (RSV)
Characterized
by prominent expiratory
wheezing and clinically resembles asthma
Assessment
Distinguish from
asthma
A low-grade fever often exists
Major distinguishing factor is age
Asthma does not occur < 1 year of age
Management
Administer humidified
oxygen by mask or blow-by
method
Support ventilations
Equipment for intubation should be readily
available
Consider bronchodilator by nebulizer
An
infection of the lower airway and lungs
Bacterial or viral
Most
commonly appears in infants, toddlers,
and preschoolers ages 1–5 years
Assessment
History of a respiratory infection
Low-grade fever, decreased breath sounds,
crackles, rhonchi, and pain in the chest area
Management
Ensure a patent airway and administer
supplemental oxygen
Support ventilations as needed
Emotional and psychological support to the
parents
A
foreign body can enter the lower airway if
it is too small to lodge in the upper airway
The foreign body can act as a one-way valve
May trap air in distal lung tissues or prevent
aeration of distal lung tissues
Assessment
History often includes information about the
child having a foreign body in the mouth
Considerable, often intractable, coughing
May have diminished breath sounds
Management
Management of an aspirated foreign body is
supportive
Inadequate
Ultimately results in tissue hypoxia and
metabolic acidosis
Shock
perfusion of the tissues
is an unusual occurrence in children
Will lead to cardiopulmonary arrest
Causes
Hypothermia, dehydration, infection,
septicemia, trauma, and blood loss
Compensated shock
The body is able to compensate
for decreased
tissue perfusion through various physiological
mechanisms
Signs and symptoms
Irritability or anxiety
Tachycardia
Tachypnea
Weak peripheral pulses, full central pulses
Delayed capillary refill (more than 2 seconds in
children less than 6 years of age)
Cool, pale extremities
Systolic blood pressure within normal limits
Decreased urinary output
Decompensated
Compensatory mechanisms begin to fail
Blood pressure falls
Signs and symptoms
Lethargy or coma
Marked tachycardia or bradycardia
Absent peripheral pulses, weak central pulses
Markedly delayed capillary refill
Cool, pale, dusky, mottled extremities
Hypotension
Markedly decreased urinary output
Absence of tears
Irreversible
Treatment measures are inadequate or too late
to prevent significant tissue damage and death
Despite resuscitation, organ death occurs
Best treatment is prevention
Shock
Cardiogenic
Hypovolemic
Obstructive
Distributive
May
can be classified in a number of ways:
be classified into two categories:
Cardiogenic
Non-cardiogenic
Hypovolemic
Results from loss of intravascular fluids
Treatment
Airway management
Fluid bolus

respiratory distress, congestive heart failure, or
a “cyanotic spell”
Congenital
Administer high-flow, high-concentration oxygen
Heart Disease (cont.)
Ventilate as necessary
Start an intravenous line
Monitor ECG
If the patient is having a cyanotic spell:
Place the child in the knee–chest position facing
downward
Older child can squat
Cardiomyopathy
A disease or dysfunction of the cardiac muscle
Can be result of congenital heart disease or infection
Cardiomyopathy causes mechanical pump failure
Signs and symptoms

engorgement of the liver, and peripheral edema
Cardiomyopathy
Supplemental oxygen should be administered
IV access
(cont.)
Restrict fluids
Should be treated with furosemide and pressor
agents (dobutamine, dopamine)
Dysrhythmias
Dysrhythmias in children are uncommon
Bradydysrhythmias are most common
Dysrhythmias can cause pump failure ultimately
leading to cardiogenic shock
Very limited capacity to increase stroke volume
Supraventricular
Narrow complex tachycardia
tachycardia
HR > 220 bpm
Does not allow time for adequate cardiac filling
Signs and symptoms

The main concern associated with diarrhea is
dehydration
Treatment is primarily supportive
Diabetes
can occur in very young children
Diabetic children can have great swings in
their blood glucose levels
Hypo and hyperglycemia possible
Very
young children can develop
hypoglycemia without having diabetes
Diabetic
children increase their risk of
hypoglycemia through overly strenuous
exercise, too much insulin, and dehydration
from illness
Assessment

Management
Monitor the ABCs
Obtain glucose
In the conscious, alert
patient, administer oral
fluids with sugar or oral
glucose
Glucagon or Dextrose

Hyperglycemia
may lead to dehydration and
diabetic ketoacidosis
Causes include:
Eating too much food relative to injected insulin
Missing an insulin injection
Defective insulin pump
Illness or stress
Assessment
Dehydration
