Q

What is ABG?

A

Arterial blood gas (ABG)
sampling of blood levels of oxygen & carbon dioxide within the arteries, opposed to venous blood.
Acidity, or pH, of the blood is measured simultaneously with the gas levels in ABG sampling.

16
Q

What must be determined before resection?

A

Firm diagnosis of malignancy

17
Q

What is the goal in surgical treatment of cancer?

A

Curative resection, with minimal removal of lung tissue

18
Q

Is resection of the parietal structures possible?

A

Yes, feasible

19
Q

What is peri-operative death?

A

Death within 2 weeks of a surgical procedure

20
Q

What are the reasons for peroperative death?

A

ARDS
Bronchopneumonia
Myocardial Infarction
PTE
Pneumothorax
Intrathoracic bleeding

21
Q

What is ARDS?

A

Acute respiratory distress syndrome
Condition that leads to low oxygen levels in blood.
Fluid builds up in the air sacs
prevents lungs from filling with air & moving enough oxygen into bloodstream.

22
Q

What does PTE stand for?

A

Pulmonary thromboembolism

23
Q

What non-fatal complications exist after an operation?

A

Pain
Empyema
BPF
Wound infection
AF
MI
Post-op respiratory insufficiency
Gastroparesis/constipation.

24
Q

What does BPF stand for?

A

Bronchopulmonary fistula

25
Q

What does MI stand for?

A

Myocardial infarction

26
Q

What is gastroparesis?

A

Spontaneous movement of the muscles (motility) in your stomach does not function normally

27
Q

When is it difficult to assess the size of a tumour?

A

Because of collapse of a lobe or lung

28
Q

What are the commonest problems with staging of lung cancer?

A

Presence of another pulmonary nodule
Retrosternal thyroid
Adrenal Nodule - benign tumour in the adrenal gland

29
Q

What is a retrosternal thyroid?

A

The abnormal location of all or part of the thyroid gland below the breastbone (sternum)

30
Q

Define pneumonectomy

A

Surgical removal of a lung or part of a lung.

31
Q

When might be confused for cancer?

A
Tb, lung abscess
Benign tumour - hamartoma
Granuloma 
Fibrosis
Paraffinoma
32
Q

Define hamartoma

A

Disorganised mass of cells. The cells are the same as those found in the local area, non- malignant. Growth rate is equal to that of the surrounding area

33
Q

Define parrafinoma

A

Injection of paraffin causing a tumefaction, usually a granuloma

34
Q

What is the operative mortality rates for lung cancer

A

Pneumonectomy 5-10%
Lobectomy 3-5%
Wedge resection 2-3%
Open/ close thoracotomy 5%
