169
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
170
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
171
Q

Heart

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

193
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 occurso Signs include decreased or absent retractions going to fatigue, altered mental status owing to inadequate oxygenation and an abnormally low respiratory rateo Decompensated state

194
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

195
Q

  • 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
196
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
197
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

199
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

200
Q

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

201
Q

o A child and compensated shock

A

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

202
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

203
Q

o A child in decompensated shock may have

A

an altered appearance, reflecting inadequate perfusion of the braino Hypertension is it late and I’m gonna sign in an infant or younger child an urgent intervention is needed to prevent cardiac arrest

204
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
205
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
206
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
207
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
208
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
209
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
