A new study, published in the latest issue of the Journal of Small Animal Practice (JSAP), demonstrated that placement of temporary tracheostomy tubes following multi-level airway surgery for brachycephalic obstructive airway syndrome (BOAS) is helpful in managing postoperative airway obstruction and has a low mortality rate.
Outcome of temporary tracheostomy tube-placement following surgery for brachycephalic obstructive airway syndrome in 42 dogs1 was undertaken at Dick White Referrals, UK. A retrospective case series of dogs that had a temporary tracheostomy tube placed in the post-operative period following surgery for BOAS was obtained from the referral hospital.
Of the 42 dogs, 11 had a tracheotomy tube placed electively and 31 had one placed as an emergency. The overall postoperative complication rate in the study was 95%. The minor complication rate – defined as resulting in no observable compromise of the clinical status and/or self-limiting, such as a cough - was 71%. The major complication rate – defined as resulting in discernible harm to the patient, such as cyanosis and dyspnoea - was 83%. Overall, 41/42 dogs were classified as having successful tracheostomy tube management.
Marius Stordalen, lead author of the paper said: “Contrary to what had been previously thought, this manuscript shows that in an appropriate clinical setting, temporary tracheostomy tube placement following multi-level airway surgery for brachycephalic obstructive airway syndrome carries a good prognosis for the majority of patients."
Nick Jeffery, editor of JSAP concluded: “Whilst overall mortality rate was low following placement of a tracheostomy tube in the postoperative period, there was a high overall complication rate. This finding demonstrates the need for continuous monitoring and intensive care for patients following placement of tracheostomy tube.”
