Q

Pleurodesis

A

Used to scar the lining of the lung

Used in people that have recurrent effusions

ABX and cautery

20
Q

Simple pneumo

A

“Collapsed” lung - with no change in vitals

Urgent txt to expand lung

21
Q

Tension pneumo

A

Vital sign changes

Needle decompression then thoracostomy

22
Q

Open pneumo

A

Penetrating

Sucking chest wound

23
Q

Closed pneumo

A

Blunt trauma

Intact chest wall

24
Q

Causes of spontaneous pneumo

A
Smoker
Marfan’s
Thin build
Emphysema / blebs
CF
Lung CA
25
Q

Causes of traumatic pneumo

A

Blunt chest trauma
Penetrating trauma
Barotrauma
Thoracic procedures

26
Q

Txt for pneumo

A

Simple - thoracostomy
Tension - needle decomp
Open - one-way valve (chest seal), then thoracostomy
Closed - thoracostomy

27
Q

Causes of pulmonary infiltrates and consolidation

A
Pneumonia
Pulmonary contusion 
Inhalation injury
Sepsis
ARDS
28
Q

Txt for pulmonary infiltrates

A

ABX
Antifungals
Ventilatory support
Aggressive pulm toilet

29
Q

Lung masses that are touching bronchus can lead to

A

Cough / hemoptysis

30
Q

Lung mass in pleura can lead to:

A

Chest wall pain

31
Q

Lung masses that cause narrowing of the bronchus can lead to

A

Atelectasis

32
Q

Lung masses in the mid parenchyma away from bronchus can lead to

A

Hemoptysis

33
Q

NSCLC leads to what paraneoplastic syndrome?

A

Hypercalcemia
PTH-like substance is produced
Metastasis to the bone

34
Q

Small cell lung cancer leads to what paraneoplastic syndrome?

A

ADH like substance

SIADH -> low serum Na

MSH production -> hyperpigmentation

ACTH production -> increased cortisol -> Cushings -> glucose intolerance

35
Q

Pancoast tumor leads to what paraneoplastic syndrome?

A

Brachial plexus, cervical lymph chain

Ulnar nerve compression

Horner’s triad

SVC syndrome

36
Q

Tissue dx of lung masses

A

Bronchio-alveolar lavage - inject saline, aspirate out and send for cytology

Trans-bronchial bioppsy - biopsy through bronchial wall

Endobronchial ultrasound — FNA of mediastinal nodes / mass

37
Q

Percutaneous trans-thoracic biopsy

A

CT or fluoro guided - through chest wall

38
Q

MC primary types of lung CA

A

Adenocarcinoma

Squamous cell carcinoma - often central

39
Q

Common sites of metastasis

A

Lung
Liver
Bone
Brain

40
Q

Q

Malignant lung masses

A
More than 2cm
Increased or unstable over 24 mos
Irregular calcifications
Spiculated border
Multiple lesions
43
Q

Unresectable

A

Tumor has invaded vital structures - can’t cut it out

44
Q

Inoperable

A

Unstable pt due to comorbidities

45
Q

Cancer staging

A

T - tumor size (cm)
N - nodal involvement
M - metastasis (y/n)

46
Q

are you pleural effusion?

A

Cause i cant breath when youre around
