Q

What is the management of croup?

A
  1. Basics - minimal handling. Supplemental oxygen or respiratory support if required in severe cases. 2. Place and person - admit to hospital if worried about increased WOB or hypoxia. 3. Investigations and definitive diagnosis - clinical diagnosis 4. Management - oral prednisolone (1mg/kg), oral dexamethasone (0.15 - 0.6 mg/kg), IV dexamethasone (0.2mg/kg), nebulised adrenaline (1:1000), ETT 5. Long term

Q

What would you consider for “Place and Person” in a child with bronchiolitis, when deciding whether or not to admit them?

A
  • Oxygen requirement - if requiring oxygen to maintain SpO2 > 93% admit
  • Apnoeic episodes - marker of severity
  • Behaviour - poor feeding, lethargy and irritability are signs of severity
  • Work of breathing

Q

What is the management of bronchiolitis?

A

Basics

  • DRABC
  • Vital Signs

Place and Person

  • Assess severity
  • If increased WOB, requiring O2 to maintain SpO2 > 93%, apnoeas or lethargy/poor feeding/irritabilty –> ADMIT [if RURAL - if parents are anxious / nervous / “irresponsible” or if live far away]

Ix and confirm diagnosis

  • Usually aclinical diagnosis
  • If diagnostic uncertainty, can do CXR

Definitive Management

  • Supportive management
    • Minimal handling and frequent feeds’
  • Oxygen via NP / HFNP
  • NGT / IV fluids if poor feeding
  • Can be discharged once maintaining adequate oxygenation and adequate feeding
  • Can triabl salbutamol if 2 years old to see if salbutamol responsive

Follow Up

  • Follow up with GP
  • Educate RE signs to return (apnoeic, lethargic, poor feeding, wheeze, increased WOB)

Q

What are the typical symptoms/ signs of croup?

What is added to make this bacterial tracheitis?

A

URTI followed by barking cough, hoarse voice, wheeze [even though LRTI], increased WOB

If there is also high fever + toxic looking child –> consider BACTERIAL TRACHEITIS [OR EPIGLOTTITIS FOR THAT MATTER?!]

24
Q

What is the management of croup?

A

Basics

  • DRABC
  • Vitals

Place and Person

  • Do they need to be admitted?
    • Stridor at rest
    • Requiring O2 - VERY LATE SIGN
    • Increased lethargy/irritability
    • Poor feeding
    • Live far away [rural]
    • Parents don’t seem “sensible” [rural]

Ix and Confirm Diagnosis

  • Want to avoid over-investigating because can worsen
  • CXR if uncertainty: steeple sign if severe

Definitive management

  • Mild: D/C home and supportive care. Freqeunt small feeds and minimal handling
  • Moderate:
    • Oral corticosteroids:
      • 1mg/kg prednisolone
      • 0.15mg/kg dexamethasone
  • Severe:
    • Nebulised adrenaline
    • plus oral steroids as above

Follow Up

  • DC once no stridor at rest
  • Follow up with GP a few days later
  • Educate RE signs to come back in
25
What are the markers of severity for croup?
Stridor at rest Poor feeding Lethargy / irritability Increased WOB Reduced SpO2 is a very late sign
26
What is the aetiology of epiglottitis?
Haemophillus infleunzae Or, if immunised, more likelt to be Beta haemolytic strep Moraxella catarrhalis Strep pneumoniae
27
What are the causes of epiglottitis in an **immunised** child?
Group A Strep Moraxella Catarrhalis Streptococcus Pneumoniae
28
How do you differentiate between croup and epiglottitis?
Croup * sickness comes on over a few days * Preceeding URTI symptoms * Not usually with high fever * Miserable * Loud, barking, brassy cough * Loud, harsh stridor * Hoarse voice * Able to drink, not drooling Epiglottitis * Comes on suddenly * No preceeding URTI symptoms * High fever * Flat / flopppy * Soft, muffled cough * Soft stridor * Quiet voice, reluctant to speak / dysarthria * Dysphagia and drooling
29
What is the management of epiglottits!
Straight to ED Secure the airway (be prepared to perform a crycothyroidectomy) Take bloods once intubated Empiral antibiotics (Ceftriaxone) Treat contacts with Rifampicin prophylactically
30
What is the aetiology of cystic fibrosis?
autosomal recessive mutation on chromosome 7 inteferes with CFTR gene which cuases altered ion transportation across epithelial cells
31
What are the clinical features of CF?
Respiratory * Thickened secretions * Recurrent infections * Bronchiectasis * Recurrent pneumothroacies * ABPA * Nasal polyps * Chronic sinusitis Pancreas * Exocrine insufficiency (which then blocks the endocrine ducts) * Malabsorption * Steatorrhea * Failure to thrive * Recurrent pancreatitis * T1DM Hepatobiliary System * Prolonged neonatal jaundice * Hepatic cirrhosis * Portal HT * Fat soluble vitamin deficiency (vitamin ADEK) * Recurrent cholecystitis GIT * Meconium ileus * DIOS Reproductive system * Absence of vas deferens * Delayed puberty due to malnutrition * Infertility
32
What is involved in testing for CF using the Gutehrie Test?
1. First Test for IRT (immunorecative trypsinogen level) 2. If this is high - then test for CFTR
33
What is the screening test for CF? What is the diagnostic test?
Screening test = Gutherie Heel Prick (IRT & CFTR) Diagnostic Test = Sweat Test
34
If you had a child with symptoms of CF, what FIRST investigation would you order?
Sweat Test (Sweat chloride levels \>60mmol/L = diagnostic of CF) NOT the heel prick test, this is a screening test
35
What is the overall management of CF?
Basics * Explain there is NO CURE - only manage potential complications **Place and Person** * Referral to paediatrician, respiratory physician, allied health including physiotherapists and dieticians **Ix and CD** * Sweat Test if not already done **Definitive Management:** *Think of each system* * Respiratory * physiotherapy * aerolysed mucolytics * ABx if infection, also given resuce antibiotics * Lung transplant (last line) * GIT & Pancreas * High calorie diet * Pancreatic enzyme replacement (Creon) * Fat solumble vitamin replacement (A,D,E,K) * Salt replacement occasionally * Insulin later in life Prevntative / Ongoing * Flu vaccine * Pneumococcal vaccine * NO SMOKING * Avoid sick people * Regular follow up * Yearly mucous cultures taken (and at every exacerbation). Eventually get infected with pseudomonas. * DEXA scan at puberty *
