Q

Neck and airway

A
  • The airway of a young child is also smaller than an adult airway making it more prone to obstruction
  • During the first 4 to 6 months of life infants are obligate nose breathers and nasal obstruction with mucus can result in significant respiratory distress
  • The narrowest part of a young child airway occurs at the level of the cricoid cartilage rather than at the vocal cords as an adult

Q

Chest and lungs

A
  • A child’s chest wall is quite then making it easy to hear heart and lung sounds but also means that sounds are transmitted throughout the chest
  • Children have fewer rib fractures and flail chest events however thoracic organs may be more severe
  • Children are more vulnerable than adults the pulmonary contusions, cardiac Tampa nod and diaphragmatic rupture
  • Signs of a pneumothorax or haemothorax and children are often subtle

Q

Abdomen and pelvis

A
  • abdominal distension in a healthy infant is due to two factors the weakness of the abdominal wall muscles and the size of the solid organs
  • liver extends below the rib cage in infants
  • Abdominal injuries are the second leading cause of serious trauma in children
  • The liver and spleen extend below the rib cage and do not have much boney protection as they do in an adult the kidneys as well

Q

Work of breathing

A
  • Listening for abnormal airway sounds and looking for signs of increased breathing effort
  • Abnormal positioning and retractions are physical signs of increased work of breathing that can easily be assessed without touching the patient
  • Combined the characteristics of work of breathing abnormal airway sound, abnormal positioning, retraction, and nasal flaring to make your general assessment

Q
  • Retractions
A

represent the recruitment of accessory muscles of respiration to provide more muscle power to move air into and out of the lungs in the face of airway or lung disease or injury

o May be evident in the Super clavicular area above the clavicle, the intercostal area between the ribs, or the sub sternal area under the sternum

o Head bobbing is another form of retractions

Q
  • Acceptable blood pressure in children 1 to 10 years is determined by
A

70 + (2 x age)

24
Q
  • Immediate transport
A

for trauma and the child has a serious mechanism of injury, physiological abnormality, potentially significant anatomic abnormality, or if the scene is unsafe

  • In these cases stabilize the spine, manage the airway and breathing, stop external bleeding and begin transport attempt vascular access on the way
25
Q

Focused history and physical exam

- Four objectives:

A

o Obtain complete description of the chief complaint using sample and OPQRST
o Determine the MOI or nature of illness
o Perform rapid trauma or medical assessment
o Obtain baseline and subsequent vital signs

26
Q

Ongoing assessment

A
  • Include the PAT, reassessment of patient priority, vital signs every five minutes for unstable every 15 minutes for stable, assessment of effectiveness of interventions, and reassessment of focussed examination areas
27
Q
  • Respiratory distress
A

increased work of breathing to maintain oxygenation or ventilation it is a compensated

o State in which increased work of breathing resulting in adequate pulmonary gas exchange

o Hallmarks of respiratory distress are classified as mild, moderate or severe these include retractions, abdominal breathing, nasal flaring and grunting

28
Q
  • Respiratory failure
A

Can no longer compensate for underlying pathologic or anatomic problem by increased work of breathing so hypoxia and carbon dioxide retention occurs

o Signs include decreased or absent retractions going to fatigue, altered mental status owing to inadequate oxygenation and an abnormally low respiratory rate

o Decompensated state

29
Q
  • Respiratory arrest
A

implies that patient is not breathing spontaneously

o administer immediate bag mask ventilation with supplemental oxygen to prevent progression to cardio pulmonary arrest

30
Q

Foreign body aspiration or obstruction

A
  • In the absence of fever, cough or respiratory congestion suspect foreign body aspiration when a child has a sudden onset of respiratory distress accompanied by coughing, gagging, strider or wheezing
31
Q

Epiglottitis

A
  • The severe inflammation of supraglottic structures usually due to bacterial infection
  • Classic presentation is easily distinguished using the PAT and initial assessment the child will look sick and anxious, will sit up right in the sniffing position and maybe drooling because of an inability to swallow secretions
  • The work of breathing is increased, and pallor or cyanosis may be evident there may be strider, muffled voice, decreased or absent breath sounds and hypoxia
32
Q

Bronchiolitis

A
  • Is an inflammation of small airways in the lower respiratory tract due to viral infection
  • An infant with a first time wheezing episode occurring in the late fall or winter likely has bronchiolitis
  • Mild to moderate retractions, tachypnea, diffuse wheezing and diffuse crackles and mild hypoxia characteristics
33
Q

Bag mask ventilations

A
  • Deliver breath at a rate of 12 to 20 breaths per minute for infants and children squeeze in the bag only until you see chest rise
  • Ventilate at the appropriate rate and volume over approximately one second until the chest visibly rises do not hyperventilate
34
Q
  • Tachypnoea without retractions or abnormal airway sounds
A

is common in an infant or child with primary cardiac problems it is a mechanism for blowing off carbon dioxide to compensate for metabolic acidosis related to poor perfusion

35
Q
  • For suspected cardiovascular compromise
A

start with airway and breathing and provide support care as needed

  • Ensure adequate oxygenation and ventilation and then assess the circulation by checking heart rate, pulse quality, skin CTC, and blood pressure
36
Q

o A child and compensated shock

A

tachycardia and signs of decreased peripheral perfusion such as cool extremities with prolonged Capillary refill

37
Q
  • Decompensated shock
A

shock is a state of inadequate perfusion in which the bodies on mechanisms to improve perfusion are no longer sufficient to maintain a normal blood pressure by definition a child a decompensated shock will be hypotensive for his or her age

38
Q

o A child in decompensated shock may have

A

an altered appearance, reflecting inadequate perfusion of the brain

o Hypertension is it late and I’m gonna sign in an infant or younger child an urgent intervention is needed to prevent cardiac arrest

39
Q

Hypovolemic shock

A
  • Most common cause of shock in infants and young children with lots of volume occurring due to illness or trauma
  • The child may appear pale, modelled or cyanotic
  • Signs of dehydration such as sunken eyes, dry mucous membranes, poor skin turgor or delayed calf refill with cool extremities
40
Q

Distributive shock

A
  • Decreased vascular tone develops, resulting in vasodilation and third spacing of fluids due to increased vascular permeability
  • May be due to sepsis, anaphylaxis and spinal cord injury
  • Early in distributive shock the child may have warm flushed skin and bounding pulses as a result of peripheral vasodilation
  • The symptoms and signs of late distributive shock will look much like hypovolaemic shock on initial assessment fever is a key finding in septic shock
41
Q

Obstructive shock

A
  • There is impaired filling of the heart thus reduce cardiac output
  • A child with obstructive shock usually has a history of abrupt onset symptoms of shock and or a history of trauma to the chest
  • Sign specific to the underlying cause such as asymmetric chest rise an absent breath sounds on the side of a tension pneumothorax, or muffled heart sounds and an elevated jugular venous pressure in cardiac tamponade
42
Q

Cardiogenic shock

A
  • Is the result of a pump failure
  • Myocardial function is poor
  • Uncommon in paediatric and less they have an underlying congenital heart disease
43
Q

Bradydysrythmias

A
  • Most often occur secondary to hypoxia rather than as a result of primary cardiac problem
  • Initiate electronic cardiac monitoring as part of your initial assessment
  • If the child’s pulse rate is lower than normal for age but perfusion is poor despite providing adequate oxygenation and ventilation begin chest compressions and ventilations
44
Q

Menegitis

A
  • Entails inflammation or infection of the meninges the covering of the brain and spinal cord
  • most often caused by a viral or bacterial infection
  • Viral meningitis is rarely a life-threatening infection bacterial meningitis is potentially fatal
  • Young infants will have to have a fever, lethargic, irritability, poor feeding at a bulging fontanel along with neck stiffness
45
Q
  • Meningococcal meningitis with sepsi
A

is typically characterized bypetechial (small purple nonblaching spots on the skin or purpuric (larger purple or black spots) rash in addition to other menegitis symptoms

46
Q

Febrile seizures

A
  • Child must be between three months and six years old have a fever and no identifiable precipitating cause
47
Q
  • Simple febrile seizure
A

brief generalized tonic clonic seizures lasting less than 15 minutes that occur in a child without underlying neurologic abnormalities

48
Q
  • Aytipical febrile seizure
A

: longer than 15 minutes, or focal or occur in a child with baseline developmental or neurologic abnormalities

49
Q
  • Status epilepticus
A

: is defined as a condition in which seizures recur every few minutes or last more than 20-30mins

50
Q

Sudden Unexpected Infant Death 3 causes

A
  1. Sudden infant death syndrome
  2. Unkown cause
  3. Adccidental suffocation and strangulation in bed
51
Q

Brief resolved unexplained event (BRUE)

A
  • A brief resolved unexplained event formally known as an apparent life-threatening event is an episode during an infant becomes pale or cyanotic chokes gags or has an acne expel or loses muscle tone
52
Q

Burns

Assessment

A
  • For infants to head and trunk each account for 18% of body surface area, the arms each count as 9% and the legs each count as 13.5%
53
Q

CSF

- Hydrocephalus

A

is a condition resulting from impaired circulation in absorption of CSF leading to the increase size of the ventricles and increased ICP

54
Q
  • CSF shunts
A

: inserted to drain excessive fluid from brain normalizing ICP

o When pressure buildup in ventricle the one-way valve opens and CSF drains into the peritoneum word is reabsorbed

55
Q
  • A CSF shunt obstruction
A

occurs when the drainage of fluid from the brain through the shunt becomes blocked without adequate fluid drainage the CSF fluid continues to accumulate resulting in increased ICP
- Typical symptoms include headache, fatigue, vomiting
