OBJECTIVE: To describe the complications and short-term outcome following the use of perioperative nasotracheal oxygen administered through a nasotracheal tube (NTT) placed prophylactically or as a rescue during anesthetic recovery for brachycephalic dogs.
METHODS: 35 brachycephalic dogs were included in this retrospective study. Medical records were searched between January 2017 and September 2025 for dogs with brachycephalic obstructive airway syndrome that received supplemental oxygen through an NTT during the anesthetic recovery period. Dogs were divided into 2 groups depending on timing of tube placement. Tubes were placed prophylactically prior to extubation or as a rescue when reintubation was required. Follow-up information was obtained from medical records, referring veterinarians, or a phone call with the owner.
RESULTS: Minor complications associated with NTTs occurred in 23% of dogs (8 of 35). Non-tube-related complications occurred in 63% of dogs (22 of 35), with severe respiratory complications occurring in 17% of dogs (6 of 35). Four of 6 dogs (67%) with severe respiratory complications had rescue tubes. Nasotracheal tubes were successful in 66% of dogs (23 of 35). Success was associated with 10-Fr or larger tubes.
CONCLUSIONS: Nasotracheal oxygen supplementation was another tool to assist in successful anesthetic recovery of high-risk brachycephalic dogs. Larger tubes were associated with improved success rates.
CLINICAL RELEVANCE: NTTs placed either prophylactically or as a rescue were generally well tolerated. Dogs that undergo rescue tube placement may experience severe postoperative respiratory complications, including temporary tracheostomy, need for mechanical ventilation, and euthanasia or death. Further evaluation on timing of NTT placement is warranted.
