Viral NPA culture nad Pcr
PNA pertussis
Blood cultures?sepsis
Mycoplasma/chlamydia
CXR not necessary in mild P
CRP not necessary does not dd viral/bacterial
FBC may aid dd viral/bacterial

A
Heart failure
Bronchiolitis
Sepsis
Inhaled FB
Metabolic acidosis
Asthma exacerbation with viral induced illness
17
Q

CXR in pneumonia when

A

Severe pneumonia
?CCF
Complications eg pl effusion

18
Q

Management of mild pneumonia

A

Oxygen if necessary
Oral antibiotics amoxicillin 25-30mg /kg tds
IV benzepenicillin 60mg/kg QID
Mycoplasma macrolides roxithromycin 4mg /kg bd

19
Q

Severe pneumonia treatment

A

Oxygen
Antibiotics
Fluids ( watch avoid SIADH)
Antibiotics 3rd generation cephalosporin 50mg/kg
Add in clindomycin 10mg/kg iv tds toxin clover staph strep
Add Azithromycin atypical
Add Vancomycin MRSA

20
Q

A positive NPA viral rules out bacterial cause for pneumonia T/F

A

False 50% can have an associated bacterial infection

21
Q

Bacterial pneumonia

A
Usually a lobar Pneumonia 
Pneumococcus/ S. Aurueus/ H Influenza common m/o
Treat with an antibiotics for 7-10 days
Complications pl effusion 
Emphysema
Necrotising P
Abscess 
Should respond to antibiotics in 48hours if does not consider addition of 3rd generation cephalosporin  ( cephtriaxone 50mg /kg)if not responding to the antibiotics
22
Q

Pneumococcus Pneumonia features

A
Normally use amoxicillin/ penicillin 
Vaccination reduces the incidence 
Normal kids prevenar13 x3
At risk eg ATSI 4th prevenar 13 at 12/12
And PPV23 at 15years
23
Q

Staph aureus Pneumonia

A

If SEVERE Pneumonia always cover add in clindomycin good for toxins and if ?MRSA vancomycin

24
Q

Viral pneumonia

A

Common viruses are RSV paraInfluenza Influenza A/B
Adenovirus. Usually from URT
Symptoms coryza, fever, coug
Signs are bilateral wheezing cracked recession reduced Oxygen stat
APONEA in infants
CXR hyperinflation diffuse patchy
NPA
Treatment is conservative management
But 50% have co infection so watch for need for antibiotics
Rare complication Bronchiolitis obliterans adenovirus
Or Bronchiectasis

25
Q

Pneumonia in infants/neonates

A

Group B strep
Seen in prolonged rom, chorioamniocentesis prem labor
Associated with rapid deterioration in neonates
CXR shows diffuse / focal
Treatment iv ampicillin and gentamicin

Chlamydia
Pneumonia first 3months of life 
50% conjunctivitis 
Pneumonia 10-20%
Dx conjunctival inclusion body /NPA culture /serology
Treatment erythromycin 14/7
Chlamydia
26
Q

Complications of pneumonia (8)

A
SIADH
Pl effusion 
Empyma
Necrotising P
Lung abscess
Resp failure ARDS
Sepsis
Bronchiectasis
27
Q

Pleural effusion

A
Common complication of pneumonia
Assoc with chest pain / dysponea
Dull to percussion 
Decreased breath sounds 
Ix CXR/USS ( volume estimate type watery or thick/fibrous)
Treatment 
Small conservative watch and antibiotics 
Large /resp distress. Drain
28
Q

SIADH

A

Can be a complication of pneumonia
HypoNa+ and fluid retention
Treatment is fluid restrict 2/3 and very carefully replace Na+

29
Q

Empyma

A

Extension of a pl effusion
Pus in the intrapl space
Consider this if fever >48hours despite proper antibiotics
Diagnosis CXR /USS fibrous strands thick
Treatment is antibiotics
Chest drain ( if very thick ?use urokinase to thin it down)
Aspiration ( likely to reaccumulate)
VATS surgical drainage
Monitor inflammatory markers

30
Q

If pleural fluid is drained send for micro and cytology

A

Micro bacterial C/S
STAIN AFB
Step pneumonia Ag test
16SPCR

Cytology
Raised lymphocytes?malignacy /TB

31
Q

Necrotising pneumonia

A

Rare/sever/sepsis
Often have a pl effusion
Abscess +/- broncholpleural fistula
Good prognosis if managed correctly
S. Aureus/ S pneumonia/ mycoplasma
Diagnosis CXR /CTscan ( esp if surgery being considered )
Treatment is prolonged antibiotics IV / +/- chest tube/ +/- surgery

32
Q

Lung abscess

A

Can be part of necrotising pneumonia
Cavitation inflmatatory lesion
Can be caused by inadequate treatment of a lobar pneumonia
Can be assoc with an aspiration ( FB/Vomit)
CXR thick walled lesion with an air filled level

33
Q

Air filled /thin walled sac
Associated with Staph Aureus
Risk of broncholpleual fistula / pneumothorax
Associated with empyma
