Surgery.

Wolters Kluwer Health, 2014: 281.
Thoracic surgery commonly involves fiber optic
bronchoscopy. What is the smallest endotracheal
tube (ETT) in which a standard fiber optic
bronchoscope will pass?
8.0

What perioperative test is an adequate assessment
of pulmonary function in patients presenting for
thoracic surgery who have very little or absent
functional impairment?
Spirometry

Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 282
Patients revealing what spirometric values warrant
further testing prior to pulmonary resection?
Patients with the following spirometric values warrant further
testing prior to surgery: FEV1 (forced expired volume in 1
second) 45mmHg.

Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 282.
The majority of patients undergoing pneumonectomy
or lobectomy are placed in what surgical position?
Lateral decubitus position. This position allows a posterolateral
or lateral thoracotomy, permitting the best exposure of the
pulmonary hilum.

Manual of Surgical Procedures. 5th ed. Philadelphia, PA:

What hemodynamic changes can result when the
pericardium or hilar structures are retracted
vigorously?
Cardiac arrhythmias and hypotension can occur.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 282.
The surgeon asks the anesthetist to reinflate the
lung while he clamps the bronchus that leads to the
lobe being resected. What is the purpose of this?
To ensure that the remaining lobes inflate adequately.

Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 282.
If a chest tube is placed following a pneumonectomy,
why is a balanced drainage system imperative?
A mediastinal shift towards the operative side will occur if a
balanced drainage system is not used, resulting in severe
hemodynamic changes.

List 3 relative contraindications to lung resection.
- Right ventricular dysfunction 2. Pulmonary hypertension 3.
Preoperative hypercapnia

What are the most common preoperative diagnoses
seen in patients presenting for lobectomy or
pneumoectomy?
The most common preoperative diagnosis is carcinoma of the
lung, however patients may also present with infection (namely
bronchiectasis and mycobacterial disease), developmental
abnormalities, and trauma.

A patient presenting for lung resection has
myasthenic syndrome (Eaton-Lambert syndrome).
How would you expect the patient to respond to
depolarizing muscle relaxants? Nondepolarizing
muscle relaxants?
The patient would exhibit resistance to depolarizing muscle
relaxants and an increased sensitivity to nondepolarizing
muscle relaxants.

Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 285.
What are the benefits to the intraoperative use of
regional analgesia during a lobectomy or
pneumonectomy?
The amount of systemic analgesics and anesthetic is reduced,
thus facilitating a quick emergence.
Jaffe RA, Schmiesing CA, Golianu B. Anesthesiologist’s
Manual of Surgical Procedures. 5th ed. Philadelphia, PA:
Wolters Kluwer Health, 2014: 286-287.
Why is it important not to overhydrate a patient
during a lobectomy or pneumoectomy?
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.

- What are the most common sized double-lumen
tubes (DLT) used in men? 2. What are the most
common sized DTLs used in wormen?
- 39-41 Fr 2. 35-37 Fr

What is a wedge resection? For what reasons would
a wedge resection be indicated?
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.

What are the two most common indications for chestwall
resection.
- Primary chest-wall tumors 2. Lung cancers that have
invaded the thoracic cage

A patient presenting for chest-wall resection has
received chemotherapy with Adriamycin
preoperatively. What are the concerns associated
with this chemotherapeutic agent?
At high doses, Adriamycin is associated with cardiotoxicity.

What is empyema? How is it primarily treated?
Empyema is a collection of pus and fluid within the pleural
cavity. Drainage of the infected fluid is the primary treatment.

Empyema most commonly occurs secondary to
what disorder?
Pneumonia
