Q

The majority of patients undergoing pneumonectomy

or lobectomy are placed in what surgical position?

A

Lateral decubitus position. This position allows a posterolateral
or lateral thoracotomy, permitting the best exposure of the
pulmonary hilum.

Q

Why is it important not to overhydrate a patient

during a lobectomy or pneumoectomy?

A

Following surgery, the pulmonary vascular resistance increases
relative to the portion of removed lung tissue. Overhydration
places these patients at risk for pulmonary edema and right
ventricular failure.

Q

What is a wedge resection? For what reasons would

a wedge resection be indicated?

A

A wedge resection is the excision of a mass in a way that does
not involve total removal of an entire pulmonary segment.
Wedge resections may be perfomed in those with peripheral
non-small-cell tumors, patients with extremely limited pulmonary
reserve who could not tolerate a lobectomy, for the resection of
multiple or single metastatic lesions arising from varying primary
neoplasms, therapeutic and diagnostic purposes in lesions that
cannot be diagnosed by less invasive techniques.

Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 302

25
Q

What are common preoperative pulmonary findings

in patients presenting for drainage of empyema?

A

Mediastinal shift to the ipsilateral side, ipsilateral lung collapse,
impaired hypoxic pulmonary vasoconstriction due to infection
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:

Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 308.

31
Q

Describe the typical patient population presenting for

excision of apical blebs

A

These patients typically are young, otherwise healthy
individuals, with normal lung function.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 334

32
Q

What conditions are frequently seen in patients with

bullous emphysema?

A

Pulmonary hypertension, right ventricular dysfunction, endstage
lung disease.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 334.

33
Q

Are the majority of blebs or bullae excised through

open procedures or thoracoscopically?

A

Thoracoscopically. The goal of the procedure (regardless of
technique used) is to remove the nonfunctioning bleb or bullae.
This allows the compressed, preserved lung tissue to reinflate,
once again contributing to gas exchange.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 333-334.

34
Q

What is a major concern for patients undergoing

excision of bilateral, large bullae?

A

Tension pneumothorax/pulmonary tamponade due to the
expansion of bullae from positive pressure ventilation. It is best
to isolate the affected lung before positive pressure ventilation
is initiated.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 335.

35
Q

What measures can be taken to minimize the risk of

bulla rupture during positive pressure ventilation?

A

Use pressure-controlled ventilation

36
Q

Describe the typical patient presenting for lungvolume

reduction surgery.

A

These patients have severe emphysema, require steroids, use
supplemental oxygen and bronchodilators.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 336

37
Q

How does lung-volume reduction surgery improve

pulmonary function?

A

By reducing lung volume through the removal of diseased
tissue, elastic recoil improves and airway resistance is
decreased. The chest cavity itself is reduced, therefore
diaphragmatic and chest-wall function is improved.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 336.

38
Q

What two surgical approaches can be used for lungvolume

reduction surgery?

A

Median sternotomy, endoscopically
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 337

39
Q

Whether lung-volume reduction surgery is performed
open or endoscopically, the patient should be
extubated in the OR. Why is this?

A

To avoid unnecessary ventilatory pressures being placed on the
lungs.

40
Q

Following lung-volume reduction surgery, why are

chest tubes left to water seal and not suction?

A

To prevent the build up of negative pressure on the lung that
could disrupt staple lines.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 337.

41
Q

Why would a patient undergo a bronchopulmonary

lavage?

A

Bronchopulmonary lavage is performed in patients with
pulmonary alveolar proteinosis. This condition is characterized
by abnormal surfactant production that results in saturation of
the lungs with proteinaceous fluid. The cause of this disorder is
not well known.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 340.

42
Q

Describe the process of a bronchopulmonary lavage.

A

Bronchopulmary lavage necessitates general anesthesia with
the use of a double-lumen tube. The lung is irrigated with 500-
1000 cc’s of normal or half normal saline. This lavage washes
out and dilutes the excess surfactant, mucus, or pus, and it also
obtains specimens for histochemical and cytological
examination.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 340.

43
Q

Pulmonary alveolar proteinosis is the the most
common diagnosis seen in patients presenting for
bronchopulmonary lavage. What are other possible
preoperative diagnoses seen?

A

Cystic fibrosis, refractory asthma, inhalation of radioactive dust,
silicosis, alveolar microlithiasis, lipoid pneumonitis,
bronchiectasis
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 340.

44
Q

Typically, unilateral lavage is performed, with the
more diseased lung irrigated first. If both lungs are
equally diseased, what lung is irrigated first?

A

The left lung is irrigated first. The right lung is larger and can be
used for ventilation to provide more adequate gas exchange.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 341.

45
Q

What signs and symptoms are seen in a person with

pulmonary alveolar proteinosis?

A

Fatigue, dyspnea, cough, cyanosis, clubbing, diffuse rales,
decreased pulmonary compliance

Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 341.

46
Q

What would an ABG reveal in a person with

pulmonary alveolar proteinosis?

A

Repiratory alkalosis and hypoxemia

Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 341.

47
Q

List the most common indications for a lung

transplant.

A

Pulmonary fibrosis, emphysema, pulmonary hypertension,
cystic fibrosis. People with pulmonary hypertension typically
have normal lung mechanics but extremely abnormal cardiac
function. Patients with cystic fibrosis, pulmonary fibrosis, and
emphysema have profoundly abnormal mechanical pulmonary
function.

48
Q

Is cardio-pulmonary bybass (CBP) required for lung

transplantation?

A

No, however a CPB circuit and perfusionist should be available
at all times.
