Q

URI

When is is safe to proceed with surgery on a patient with an URI? If you had to reschedule surgery, how far out should you reschedule?

A

A patient that has had their URI for weeks and is stable can proceed with surgery.

Reschedule for 6 weeks out to avoid airway hyperreactivity period.

Q

Asthma

Inflammatory process:

A

inflammatory cascade leads to infiltration of the airway mucosa with eosinophils, neutrophils, mast cells, T cells, B cells, and leukotrienes.

Results in airway edema (esp. in the bronchi) and airway remodeling causing thickening to basement membrane and smooth muscle mass.

Q

CF

What gene mutation causes CF?

A

mutation on chromosome 7

encodes the cystic fibrosis transmembrane conductance regulator (CFTR)

slide 49

Q

CF

What does CFTR do?

A

produces a protein that aids in salt and water movement in and out of cells.

In CF, the mutated gene results in the production of abnormally thick mucus outside of epithelial cells.

Q

CF

What is the primary cause of morbidity and mortality in CF patients?

A

chronic pulmonary infection

slide 49

92
Q

CF

How does chloride transport disrupt lung function?

A

decreased chloride transport is accompanied by decreased transport of sodium and water, which leads to:
* dehydrated viscous secretions
* luminal obstruction
* destruction and scarring of various glands and tissues

slide 49

93
Q

CF

What is the diagnostic criteria?

A

sweat chloride conc. > 60mEq/L AND clinical symptoms such as:

RA to help decrease postop pulmonary complications

EKG equipment should be reversed for accurate interpretation

slide 55

right.

Normal mommas get displaced to the left.

obstruction of airflow in the trachea and mainstem bronchi

slide 57

123
Q

CAO

What causes obstruction?

think disease processes, not foreign body

A
  • tumors
  • granulation from chronic infection
  • airway thinning from cartilage destruction

slide 57

124
Q

CAO

How can we cause tracheal stenosis?

A

with prolonged intubation either with an ETT or a tracheostomy tube

125
Q

CAO

How do we prevent tracheal stenosis from artificial airways?

A

high volume low pressure cuffs

slide 57

126
Q

CAO

What does tracheal mucosal ischemia progression cause?

A
  • destruction of cartilaginous rings
  • subsequent circumferential scar formation

slide 57

127
Q

CAO

At what point does tracheal stenosis become symptomatic?

A

When the lumen is decreased to < 5 mm in diameter

Slide 58

128
Q

CAO

Tracheal stenosis symptoms?

A
  • dyspnea (even at rest)
  • accessory muscle use though all phase of respiratory cycle
  • audible stridor
  • tracheal narrowing on CT
  • flattened flow volume loops characteristic of fixed obstruction

may not develop for several weeks after extubation

slide 58

129
Q

CAO

What procedure can temporarily fix tracheal stenosis?

A

tracheal dilation via bronchoscopy with balloon dilators, surgical dilators, or laser resection of the tissue

slide 59

130
Q

CAO

Is tracheobronchial stent short or long term solution for tracheal stenosis?

A

trick question bitches, it can be both.

slide 59

131
Q

CAO

What is the most successful surgical treatment for tracheal stenosis and what kind of airway does it require?

A

surgical resection and reconstruction with primary re-anastomosis.

Requires a translaryngeal intubation

slide 59

132
Q

CAO

What anesthetic considerations are there for tracheal resection and reconstruction?

A
  • use volatiles to ensure maximal FiO2
  • may use high frequency ventilation
  • may add helium gas to facilitate anesthetics

slide 59

133
Q

CAO

How does helium gas facilitate anesthetic gasses?

A

Helium decreases the density of the gas mixture and may improve flow through the area of tracheal narrowing
