Paediatrics 1 (Cardio, GI, Neuro, Psych, Onco, MSK, Neonatal) Flashcards
Investigation: Fever in baby
- blood culture
- urine dip is not sensitive enough in under 3 months old
- send for urine microscopy
- WBC
- FBC
- U+Es
What condition should be checked for in febrile babies?
Meningitis
- weak blood brain barrier
- sample CSF
Management: febrile baby
Broad spectrum antibiotics
- cefotaxine or ceftriaxone and amoxicillin
(until culture come back)
Admit babies under 3 months with a fever > may need IV antibiotics
What is the most common cause of UTI?
E.coli
What antibiotic is used to treat E.coli UTIs in children?
IV cefuroxime
(once meningitis ruled out - doesn’t reach the blood brain barrier)
What investigation should be completed with a baby under 6 months old with a UTI?
Renal tract USS
- recurrent infections can cause scarring that can lead to long term renal problems
(or recurrent UTIs in older children)
What needs to be ruled out in a fitting child with a fever?
CNS infection
- might need an LP
What can be a cause of ineffective antibiotic treatment?
Some bacteria has Extended Spectrum Beta-lactamase producer
- resistant to all penicillins and cephalosporins
- change to meropenem
Presentation: meningitis
- Temperature
- Semi-comatose
- Purple rash on skin
Management: meningitis
ASAP
(before any investigations)
Bacterial meningitis or meningococcal sepsis:
- First line intravenous cefotaxime
Investigations: meningitis
- blood cultures
- EDTA (acid) blood for PCR
- Lumbar Puncture CSF = might delay if concerns about clotting and raised intracranial pressure
notify Public health
What bacteria causes meningitis?
Neisseria meningitidis
- gram negative diplococci
group B streptococcus
What are contraindications to a lumbar puncture?
- Findings of increased intracranial pressure
- bleeding diathesis
- cardiopulmonary instability
- soft tissue infection at the puncture site
- shock
- respiratory insufficiency
- suspected meningococcal
What is a complication of meningitis that causes petechial haemorrhages to develop on the trunk?
Waterhouse - Friderichsen syndrome
- petechial haemorrhages
- rapidly stops oxygen saturations
- severely hypotensive
What conditions should be noticed to public health?
- all meningitis
- all invasive meningococcal
- all encephalitis
Presentation: pneumonia
- short of breath
- pyrexial
- miserable
Investigations: pneumonia
- sputum culture or nose/ throat swab
- CXR = RLL change
- blood culture
What is the main cause of pneumonia?
Streptococcus penumoniae
- Gram positive cocci in pairs
Management: pneumonia
IV benzylpenicillin
PO amoxicillin
- if not improving check if child has developed an empyema in the pleural space = CXR
Define: prematurity
- under 37 weeks
At what gestation is resuscitation of a baby allowed?
from 22 weeks
management: premature rupture of membranes
- antibiotics e.g. Erythromycin for 10 days
- steroids
- IV MgSO4 = neuroprotection
What is a main problem in premature babies?
lungs are not fully formed
When is surfactant and alveoli produced in a foetus?
- surfactant = retained in type 2 pneumocystis (allow lungs to stretch and reduce surface tension)
- alveoli = absent at 24 weeks then exponential increase towards term
(from type 1 pneumocytes)
