Developmental Characteristics
• Greatest Change Occurs in first Few years of Development– Muscle
Coordination– Cognitive Process– Language Skills– Social Skills
• Understanding allows a better and more complete assessment
• Effects the Assessment Findings
Developmental Characteristics
• Development and Assessment– Knowledge of appropriate developmental
milestones– Information from Parents on child’s norm– Appropriate Communication Skills– Children will REGRESS when STRESSED
Infants and young children should be allowed to remain
in their parent’s arms.
The approach to the pediatric patient should
be gentle and slow.
A small toy may calm a child.

AppearanceAgitated, makes eye contact
Initial Assessment
– Airway - Open and maintainable – Breathing - RR 50 breaths/min, clear lungs,
good chest rise– Circulation - HR 180 beats/min; cool, dry, pale
skin; CRT 3 seconds; BP 74 mm Hg/palp – Disability - AVPU=A– Exposure - No sign of trauma, weight 8 kg
What is this child’s physiologic state?
What are your treatment priorities?
• Assessment: Compensated shock, likely due to hypovolemia with viral illness
• Treatment priorities:– Provide oxygen, as tolerated– Obtain IV access en route
• Provide fluid resuscitation– 20 ml/kg of crystalloid, repeat as needed
• 160 ml normal saline infused
• HR decreased to 140 beats/min
• Patient alert and interactive, receiving second bolus on emergency department arrival
General Management of the Pediatric Patient
• Airway Management
• Fluid and Medications
• Electrical Therapy
• C-Spine Consideration and Impact
• Transport Considerations
Summary of BLS Maneuvers
Clearing an Infant’s Airway
Suctioning
• Decrease suction pressure to less than 100 mm/Hg in infants.
• Avoid excessive suctioning time—less than 15 seconds per attempt.
• Avoid stimulation of the vagus nerve.
• Check the pulse frequently.
Pediatric-size suction catheters. • Top: soft suction catheter. • Bottom: rigid or hard suction catheter.
Suction Catheter Sizes for Infants and Children
Oxygenation
Adequate oxygenation is the hallmark of pediatric patient management.
Inserting an oropharyngeal airway in a child with the use of a tongue blade.
a. In an adult, the airway is inserted with the tip pointing to the roof of the mouth, then rotated
into position. b. In an infant or small child, the airway is inserted with the tip pointing toward
the tongue and pharynx, in the same position it will be in after insertion.
Ventilation
• Avoid excessive bag pressure and volume.
• Obtain chest rise and fall.• Allow time for exhalation.• Flow-restricted, oxygen-powered devices
are contraindicated.• Do not use BVMs with pop-off valves.• Apply cricoid pressure.• Avoid hyperextension of the neck.
In placing a mask on a child, it should fit on the bridge of the nose and cleft of the chin.
Sellick’s maneuver
Advanced Airway and Ventilatory
Management
Infant/Child Endotracheal Tubes
The Pediatric Airway
• A straight blade is preferred for greater displacement of the tongue.
• The pediatric airway narrows at the cricoid cartilage.
• Uncuffed tubes should be used in children under 8 years of age.
• Intubation is likely to cause a vagal response in children.
Pediatric Endotracheal Tube Size
• Use a resuscitation tape that estimates ET tube size based on height.
• Estimate the correct diameter, based on the child’s little finger.
Pediatric Tube Size Formula
(Patient’s age in years + 16)
4
Indications• Need for prolonged artificial ventilation• Inadequate ventilatory support with a BVM• Cardiac or respiratory arrest• Control of an airway in a patient without a
cough or gag reflex• Providing a route for drug administration• Access to the airway for suctioning
Placement of the laryngoscope.
Endotracheal Intubation in the Child
Hyperventilate the child.
Position the head.
Insert the laryngoscope and visualize the airway.
Insert the tube and ventilate the child.
Confirm tube placement.
Nasogastric Intubation
Nasogastric Intubation
Indications:
• Inability to achieve adequate tidal volume during ventilation due to gastric distention
• Presence of gastric distention in an unresponsive patient
Oxygenate and continue to ventilate, if possible.
Measure the NG tube from the tip of the nose, over the ear, to the tip of
the xiphoid process.
Lubricate the end of the tube. Then pass it gently downward along the
nasal floor to the stomach.
Auscultate over the epigastrium to confirm correct placement. Listen for bubbling while
injecting 10–20 cc of air into the tube.
Use suction to aspirate stomach contents.
Secure the tube in place.
Rapid Sequence Intubation
• Indicated in pediatric patients when intubation is difficult due to combativeness or clenched teeth.
• Neuromuscular compliance is gained by the use of a paralytic.
Circulation
Two problems lead to cardiopulmonary
arrest in children:
• Shock
• Respiratory failure
Vascular Access
• Neck veins
• Scalp veins
• Arms
• Hands
• Feet
• Intraosseous infusion
Intraosseous Infusion Indications
• Children less than 6 years of age
• Existence of shock or cardiac arrest
• Unresponsive patient
• Unsuccessful peripheral IV
Intraosseous Infusion Contraindications
• Fracture in the bone chosen for IO• Fracture of the pelvis or extremity fracture
of bone, proximal to the chosen site
Intraosseous administration.
Drugs Administered by IO Route
• Epinephrine
• Atropine
• Dopamine
• Lidocaine
• Sodium bicarbonate
• Dobutamine
Correct needle placement for intraosseous administration.
Fluid Administration
Accurate fluid dosing in children is crucial!
Electrical Therapy• Initial dose is 2 joules per kilogram
of body weight.• If unsuccessful, increase to 4 joules
per kilogram.• If still unsuccessful, focus on
correcting hypoxia and acidosis.• Transport to a pediatric critical care
unit, if possible.
Immobilizing a Patient in a Child Safety Seat
One paramedic stabilizes the car seat in an upright position and applies and maintains manual inline stabilization
throughout the immobilization process.
A second paramedic applies an appropriately
sized cervical collar. If one is not available, improvise using a rolled hand towel.
The second paramedic places a small blanket or towel on the child’s lap, then uses straps or wide tape to secure the
chest and pelvic area to the seat.
The second paramedic places towel rolls on both sides of the child’s head to fill voids
between the head and seat. He then tapes the head into place, taping over the chin, which would put pressure on the neck. The patient
and seat can be carried to the ambulance and strapped to the stretcher, with the stretcher
head raised.
Applying a Pediatric Immobilization
System
Position the patient on the immobilization system.
Adjust the color-coded straps to fit the child.
Attach the four-point safety system.
Fasten the adjustable head-support system.
The patient fully immobilized to the system.
Move the immobilized patient onto the stretcher and fasten the loops at both ends to connect to the stretcher
straps.
Emotional support of the infant or child continues during
transport.
Never delay transport to perform a procedure that can be done
en route to the hospital!
