Anaesthetic and Surgical Considerations of Brachycephalic Dogs
As previously advised, it is our preference to undertake definitive corrective procedures at the same time as assessment and examination under anaesthesia. Otherwise, anaesthetic recovery in a dog with compromised airways may be problematic. Screening blood testing – biochemistry and haematology are strongly recommended. An IV catheter is always placed. In healthy animals we use a pre-med of - Methadone – 0.2-0.3 mg/kg and Medotomidine 3-5 µg/kg.
Patients are pre-oxygenated for 10 minutes prior to induction of anaesthesia – we find this simple step significantly improves outcomes.
Induction at Veterinary Specialist Services is by Alfaxalone – 1-2mg/kg – to effect.
Following assessment of the upper airways and chonae animals are intubated with a cuffed endotracheal tube and anaesthesia is maintained with Isoflurane 1-2% and Oxygen.
The most common surgical procedures undertaken (in order of procedure) are:
Resection of the soft palate
Resection of oedematous laryngeal ventricles
Removal of tonsils
It is essential to note that each animal is an individual and not all animals require all procedures while some require alternate surgical options.
Removal of nasal turbinates is never performed at the time of initial surgery.
