Quiz - Track 1-4: Brachycephalics: What's Not to Love?

Question Title

* 2. Which of the following is a SECONDARY component of brachycephalic airway syndrome?

Stenotic nares

Elongated soft palate

Everted laryngeal saccules

Hypoplastic trachea

Question Title

* 3. Which of the following is TRUE regarding aberrant nasal turbinates in brachycephalic airway syndrome (BAS)?

Resection of stenotic nares resolves the intra-nasal obstruction of air flow in brachycephalic dogs.

Aberrant nasal turbinates are present in less than 25% of brachycephalic dogs.

Aberrant nasal turbinates are present in the majority of brachycephalic dogs and likely contribute to suboptimal outcomes after traditional BAS surgery in some dogs.

The addition of laser-assisted turbinectomy (LATE) did not improve outcome compared to traditional BAS surgery alone in the study by Liu et al (2019).

Question Title

* 4. Which of the following are treatment options for laryngeal collapse?

Sacculectomy for stage 1 collapse (everted laryngeal saccules)

Temporary tracheostomy

Permanent tracheostomy

All of the above

Question Title

* 5. Which of the following is FALSE regarding tracheostomy in brachycephalic airway syndrome (BAS)?

Temporary tracheostomy is a useful technique to facilitate anesthetic recovery after BAS surgery.

Risk factors for temporary tracheostomy are well-established and can be used to predict which patients will need a temporary tracheostomy after BAS surgery.

Dogs requiring a temporary tracheostomy have longer hospital stays and higher treatment costs compared to dogs extubated without a temporary tracheostomy.

Permanent tracheostomy has a high complication rate in brachycephalic dogs due in part to their small tracheal dimensions (diameter) and redundant skin folds.

Question Title

* 6. Which of the following is FALSE regarding gastrointestinal signs in brachycephalic airway syndrome (BAS)?

Gastroesophageal reflux and hiatal hernia result from sub-atmospheric intrapleural pressure generated by chronic airway obstruction.

Gastrointestinal signs (ptyalism, regurgitation, vomiting) are common among dogs with BAS, especially among French bulldogs.

The addition of metoclopramide to anesthetic protocols for BAS surgery may reduce the frequency of peri-operative gastroesophageal reflux and regurgitation.

Gastrointestinal signs associated with BAS did not improve after BAS surgery alone in the study by Kaye et al (2018).
