Paediatric Emergencies
A.B.C.D.E
Airway
Breathing
Circulation
Disability (depressed consciousness,
unresponsiveness).
Exposure ( significant hypothermia,
bleeding, shock).
Paediatric Challenges







Not ‘Small’ Adults
Are Someone's Child
Age groups – size, development
Opiate use intra-op/Post-op
Emergence delirium
Families
Fear of mistakes
Paediatric Considerations
Higher Anaesthetic Morbidity &
Mortality
 Higher Intra-operative Bradycardia
(Infants)
 Higher Respiratory Complications
(Recovery)
 Associated outcomes worse
 Complications occur in healthy
children of normal weight

Paediatric Anaesthesia Report
Patient specific additions
 Defer verbal report if condition is unstable
or emergency intervention is warranted.
 Birth history (premature birth, or congenital
conditions).
 Developmental considerations (ensure
personal comfort items are present, toy,
blanket, religious items).
 Special needs (e.g. glasses, hearing
implants)
 Pre-operative behaviour, (calm or
anxious).
 Loose teeth (returned for tooth fairy).

Large Tongue
Narrow Nostrils
Smaller Airway Opening
Short Neck
Neonates are obligatory nose breathers
More Susceptible to Laryngeal /
Bronchospasm
Easily Obstructed Airway
Post Intubation Oedema
Airway problems
Tracheal intubation (under 5 years)
 History of pre-term birth
 Reactive airway disease
 Airway surgery

A respiratory Rate
consistently > than 60 bpm in
a child of any age is abnormal
Normal Spontaneous
Ventilation
Minimal work
 Quiet breathing
 Easy inspiration
 Passive expiration
 Rapid in the neonate
 Decreases in older infants & children

Paediatric Considerations
(Respiratory)





High metabolic rate
Oxygen demand is higher
Infant Oxygen Consumption is 6-8mls/kg
per minute (compared to 4mls/kg for
adults)
Hypoxaemia more rapid in infants &
children
A room air Sao2 < 94% in a normal child
indicates hypoxaemia.
Causes of Respiratory
Dysfunction Post Op
Residual effects of anesthetic agents
 Opiate Agents
 Sedative agents
 Excessive fluid volume
 Pain/ Anxiety
 Hypothermia/Hyperthermia
 Pre-existing Pulmonary Disease.

Higher cardiac output
Higher baseline heart rate
Infants – cardiac output dependent on heart
rate DO NOT COMPENSATE for lower B/P
Bradycardia in an infant ominous sign (CPR
<60) May indicate hypoxaemia
B/P lower than adults and increase with age
H/R higher than adults and decrease with
age

Shivering Increases metabolic rate &
discomfort

Metabolize brown fat
Move
