Q

Symptoms of pleural effusion

A

-Dullness to percussion
-Decreased fremitus
-Decreased breath sounds
-Pleural friction rub

23
Q

Initial test of choice for pleural effusion and what is normally seen

A

CXR
-Blunting of the costophrenic angles (meniscus sign)

24
Q

What are the BEST films to evaluate for a pleural effusion?

A

Lateral decubitus

25
However, what is the GOLD standard diagnostic for pleural effusion?
Thoracocentesis
26
A thoracocentesis can be diagnostic and therapeutic. It helps distinguish between transudate and exudate. What criteria is used and what are the three parts?
Light's Criteria: an exudate is present if any of these three are present. -Pleural fluid protein: >0.5 -Pleural fluid LDH: serum LDH >0.6 -Pleural fluid LDH >2/3 upper limit of normal
27
How do you know if an empyema is present?
Pleural fluid pH < 7.2 Glucose < 40 mg or Positive gram stain
28
What should you do if an empyema is present?
Chest tube fluid drainage
29
What is a pneumothorax?
Air in the pleural space, leading to collapse of the lung from positive intrapleural air pressure
30
What is a primary pneumothorax?
Atraumatic and idiopathic with no underlying lung disease. Mainly affects 20-40 thin men, smokers, with a family history of pneumothorax.
31
What is a secondary pneumothorax
Secondary spontaneous - due to underlying lung disease (COPD, asthma, etc.)
32
A tension pneumothorax occurs when
positive air pressure pushes the trachea, great vessels, and heart to the contralateral side
33
What is a catamenial pneumothorax?
Occurs during menstruation
34
When does a traumatic pneumothorax occur?
During CPR, thoracocentesis, subclavian line placement, car accident, etc.
35
Exam findings of a patient with a pneumothorax
-Chest pain: pleuritic, unilateral, non-exertional, sudden. Dyspnea -Hyperresonance to percussion -Decreased fremitus -Decreased breath sounds
36
Also, what are the specific symptoms of a tension pneumothorax
-Increased JVP, hypotension, pulsus paradoxus
37
What is the initial diagnostic done for pneumothorax?
CXR: expiratory upright view preferred -Companion lines (visceral pleural line running parallel with the ribs) -Decreased peripheral markings
38
What is the management of a small (<3 cm) primary spontaneous pneumothorax
-Observation and supplemental oxygen -Repeat films 6 hours to exclude progression
39
What is the management of a large (>3 am) PSP?
Needle or catheter aspiration vs chest tube vs catheter thoracostomy
40
What should you do for a tension pneumothorax
Needle aspiration followed by chest tube thoracostomy
41
What should you advise the patient who has a pneumothorax?
Avoid pressure changes for a minimum of 2 weeks (high altitudes, smoking, scuba diving, etc.)
42
What is pulmonary hypertension?
Elevated mean pulmonary arterial pressure > 20 mmHg
43
What happens as a result of the increased pulmonary vascular resistance?
Leads to RVH, increased RV pressure, and eventually right-sided HF
44
Primary pulmonary HTN, which is idiopathic in nature, MC occurs in
middle-aged or young women
45
What gene defect is associated with primary pulmonary HTN
-BMPR2 gene defect
46
Symptoms of pulmonary HTN
-Dyspnea -Fatigue -Chest pain -Weakness -Cyanosis -Edema
47
Other physical exam findings in pulmonary HTN
-Accentuated S2 -Signs of Right-heart failure: increased JVP, peripheral edema, ascites -Pulmonary regurgitation, systolic ejection click
48
Diagnostics for pulmonary hypertension CXR: _______ ECG: _________ Echocardiogram: ________
-enlarged pulmonary arteries -Cor pulmonale: RVH, right axis deviation, Right BBB -large right ventricle, RVH
49
What is the definitive diagnostic for pulmonary HTN?
Right heart catheterization
50
What is seen on CBC in a patient with pulmonary HTN?
-polycythemia with increased hematocrit
51
What is the first thing that should be done with the treatment in pulmonary HTN?
Vasoreactivity trial with IV Adenosine, CCB, or inhaled Nitric oxide.
52
If vasoreactive, what is the treatment?
CCB are first line (Verapamil, Diltiazem, Nifedipine, Amlodipine)
53
Other treatment options for pulmonary HTN
-PD5-inhibitors (Sildenafil, Tadalfil) -Oxygen therapy -Long term anticoagulation in some
54
Definitive Treatment for pulmonary HTN
-Heart-lung transplant
