Consolidation Syndromes Flashcards
PULMONARY CONSOLIDATION
SYNDROMES
signs and symptoms secondary to the
collapse of the lung parenchyma with disappearance of air in the involved territory
Consolidation occurs through accumulation of inflammatory cellular exudate in the alveoli
CLASSIFICATION
- Depending on location
Systematized (lung, lobe, segment)- without displacement
Not-systematized - Related to the adjacent parenchyma:
• Not-retractile- they do not restrict the adjacent parenchyma
• Retractile - they restrict the adjacent parenchyma - Related to etiology:
• Determined by infectious / inflammatory processes
• Pneumonia
• Bronchopneumonia
• Determined by tumors
• Lung cancer
• Vascular etiology: Pulmonary Infarction
PULMONARY CONSOLIDATION
SYNDROMES- characteristics
PALPATION • ↑ tactile fremitus (when bronchia is open)→not retractile PERCUSSION • Dullness to percussion (fixed) AUSCULTATION • ↓ intensity / absence of breath sounds, replaced by • Tubular breath • Possible medium, late, or pan-inspiratory crackles • “Crepitante”
PULMONARY CONSOLIDATION
SYNDROMES
•Not retractile
•Pneumonias
1. Bacterial
2. Interstitial (atypical)
•Bronchopneumonias
BACTERIAL PNEUMONIAS
Inflammation of the alveoli and terminal airspaces in response to invasion by an infectious agent acquired through hematogen spread or airborne transmission
ETIOLOGY of bacterial pneumonia
- S. pneumoniae (pneumococcus) →Typical lobar
- pneumonia
- Staphylococcus
- Streptococcus
- Haemophilus influenzae
- Klebsiela (Friendlander bacillus)
TYPICAL LOBAR PNEUMONIA
Etiology: Streptococcus pneumoniae = encapsulated Gram positive diplococci
Involves: 1 segment / 1 pulmonary lobe
Evolution: in 3 stages/phases
- Onset
- Evolution
- Resolution
TYPICAL LOBAR PNEUMONIA
onset phase
Onset phase
Symptoms/ Sygns
▪ Sudden Onset
▪ Chills: sudden, Single rigor, prolonged (Duration 15 – 30 min) ▪ Chest pain
▪ Cough - Dry, irritating, hollow cough, at first 1 – 3 day Followed by Sputum production- dark-red, adherent ▪ Superficial respiration – Tachypnea, polypnea General sign
▪ Fever: high 390 – 400, constant pyrexia, plateau ▪ Tachycardia
▪ Altered status
Physical sign
▪ Warm teguments (febrile)
▪ Redness of face
▪ ± herpes labialis (± whole face)
Chest pain
- Severe
- Sharp / knifelike
- Localization: submammary area / basal *
- Aggravated by breath / coughing
- Immobilize the patient on the sick side
- Pleuritic pain = Results from inflamed parietal pleura
(e.g.: diaphragmatic pl. → shoulder pain
children → abdominal pain)
* Depend on pneumonia location (anatomical involvement)
TYPICAL LOBAR PNEUMONIA
Onset Phase
Respiratory system examination
inspection + palpation + precussion + auscultation
INSPECTION: superficial respiration - polypnea
PALPATION: tactile fremitus normally transmitted
PERCUSSION: discreet dullness
AUSCULTATION:
Initially: ↑ tonality and intensity of breath sounds
= bronchial breath sounds
± timber changes = hardening of breath sounds
= fremitus, breath and voice sounds are transmitted
as if they came directly from the larynx and trachea
TYPICAL LOBAR PNEUMONIA
EVOLUTION phase (the disease course)
→ After 24 – 48 hours
Duration → 7 – 10 days
Consolidation syndrome → full clinical presentation
Fever → sustained (plateau)
Dyspnea with inspiratory polypnea
Cyanosis ±
Chest Pain (pleuritic) sustained but of ↓ intensity
Cough with
Sputum: pinkish or adherent rusty sputum (containing fibrin and red cells)
→ yellowish
- Redness of face (plethora of the cheek of affected side)
- Jaundice ( hemolysis, impaired liver function)
TYPICAL LOBAR PNEUMONIA
Respiratory system examination
EVOLUTION phase
INSPECTION : ↓ chest expansion
restricted motion of the affected hemithorax
PALPATION : ↑ tactile fremitus
PERCUSSION : Dullness
AUSCULTATION :
bronchial breath sounds surrounded by fine crepitant rales, instead of vesicular breath sounds
(initially, fine crepitant rales dominate, being replaced by tubular or bronchial breath sounds)
TYPICAL LOBAR PNEUMONIA
Resolution / Recovery
- In “ crisis ”
- In “ lisis ”Characteristics:
Less well defined dullness
↓ / tubular & breath sounds disappear
Crepitant rales reappear with other characters:
coarse, unequal, mucous
Recovery in “crisis”
Sudden Before AB / 1⁄2 pt. died “in crisis” The patient state of health is aggravated suddenly Rapid temperature rise at 400 ± delirium -> Abundant sweating ↓ Fever → normal Normal pulse
Recovery “in lisis”
- Without particular clinical signs
- Apparent state of health is improving
- Body temperature begins to fall
- Cough diminishes, then disappears
TYPICAL LOBAR PNEUMONIA
LABORATORY FINDINGS
- Specific SPUTUM 1. Bacteriological examination: pneumococci Gram’s method (smear- direct exam) 2. Culture Cellularity: red cells, alveolar cells, leucocytes
TYPICAL LOBAR PNEUMONIA
Chest XRAY

TYPICAL LOBAR PNEUMONIA
PARTICULAR FORMS
1.INCOMPLETE FORM
– spontaneous healing without AB
2.ELDERLY PNEUMONIA

4. IN ALCOHOL ADDICTED
– psychiatric disorders, psychomotor agitation
TYPICAL LOBAR PNEUMONIA
OUTCOME
NATURAL (SPONTANEOUS, W/O Tretment)
- Death “in crisis”
- Complication
with TREATMENT
- Younger & Immunocompetent → healing in 5-6 days
- Elders & immunodepressed → Complications

COMPLICATIONS
Sepsis → bacteriemia: pericarditis, endocarditis, meningitis, brain abscess, nephritis, circulatory collapse
Abscess
Pleural effusion

Bronchopneumonia complications
Early onset *: local / general Late onset: bronchiectasis * E.g. Septic shock with tachycardia, hypotension, collapse Renal failure Heart failure Hypoxemia with hypercapnia Children: acute cor pulmonale
Bronchopneumonias prognosis
severe before antibiotics use
improved with treatment (etiological and supportive)
Bronchopneumonia XRAY
There is no parallel between the clinical and radiological picture bronchopneumonic foci = “shadows” with less extension - multiple - variabile intensities - irregular shape not well delimitated Some times there are foci much more dense
