“…It has been recommended that the tidal volume be maintained between 10 and 15 mL/kg when using the A/C mode in dogs with normal lungs undergoing general anaesthesia. 4 Considering the respiratory data seen during SIMV, our experimental setting, including the depth of anaesthesia, appears to be enough to deliver appropriate tidal volumes (>10 mL/kg) and regular spontaneous breathing to confirm appropriate SVV-guided fluid responsiveness.…”

We evaluated the utility of noninvasive stroke volume variation (SVV) as a functional haemodynamic predictor for fluid responsiveness under different ventilation modes [assist control (A/C), synchronized intermittent mandatory ventilation (SIMV), and continuous positive airway pressure (CPAP)] in 45 anaesthetized dogs, using an electrical velocimetry device. Receiver operating curve analysis confirmed the best predictive value during SVV (12.5% of cut-off value; 75% sensitivity and 86% specificity) followed by SVV (13.5% of cut-off value; 75% sensitivity and 75% specificity), while no statistically significance detected during SVV (P > .05). These data suggest that SVV is useful for the prediction of fluid responsiveness in laboratory dogs during A/C and SIMV, while its reliability during CPAP is poor.

“…The primary indications for mechanical ventilation are severe hypoxemia despite oxygen therapy, hypercapnia (hypoventilation) or excessive work of breathing . The reported success rates for dogs and cats who have been weaned off mechanical ventilation range from 22% to 39% . Mechanical ventilation is not a benign procedure and is associated with complications such as pneumonia, cardiovascular impairment, ventilator induced lung injury, pneumothorax, and mouth and corneal ulceration .…”

Objective As ownership of brachycephalic dog breeds rises, the surgical correction of components of brachycephalic airway syndrome (BAS) is increasingly recommended by veterinarians. This study's objective was to describe the incidence of, and strategies for the management of post-operative respiratory complications in brachycephalic dogs undergoing surgical correction of one or more components of BAS.Methods Medical records of 248 brachycephalic dogs treated surgically for BAS were retrospectively reviewed for demographic information, procedures performed, post-operative complications and treatment implemented, hospitalisation time, and necessity for further surgery.Results Pugs, Cavalier King Charles Spaniels and British Bulldogs were the most commonly encountered breeds. Dogs which experienced a complication were significantly older (mean was 5.5 years, compared with 4.1 years [P < 0.01]). Fifty-eight dogs (23.4%) had complications which included: dyspnoea managed with supplemental oxygen alone (7.3%, n = 18), dyspnoea requiring anaesthesia and re-intubation (8.9%, n = 22), dyspnoea necessitating treatment with a temporary tracheostomy (8.9%, n = 22), aspiration pneumonia (4%, n = 10), and respiratory or cardiac arrest (2.4%, n = 6). Five of the 22 dogs requiring anaesthesia and re-intubation deteriorated 12 or more hours after post-surgical anaesthetic recovery. The overall mortality rate in this study was 2.4% (n = 6). Age, concurrent airway pathology, and emergency presentation significantly predicted post-operative complications.Conclusion Our data show the importance of close monitoring for a minimum of 24 h following surgery by an experienced veterinarian or veterinary technician. Surgical intervention for BAS symptomatic dogs should be considered at an earlier age as an elective procedure, to reduce the risk of post-operative complications.

“…A low PEEP is considered sufficient to prevent collapse in healthy lungs, however higher pressures are often advocated to prevent collapse of diseased lungs. On the other hand, in case of pneumonia or other parenchymal lung diseases, where areas of the lungs may not be recruited, a higher PEEP can be dangerous and can cause overdistension of healthy areas of the lung (Hopper and Powell 2013). …”

Successful short‐term mechanical ventilation in a brachycephalic dog following aspiration pneumonia

Aspiration pneumonia is a relatively common concurrent disease in animals suffering from brachycephalic obstructive airway syndrome (BOAS). In addition to surgical correction of anatomical abnormalities, deterioration of respiratory function in these patients may warrant mechanical ventilator support to overcome severe hypoxia, hypoventilation or respiratory fatigue. Ventilation can be a life-saving procedure but is not free from contraindications, including oxygen toxicity. The authors report the successful treatment of a dog in respiratory distress following aspiration after BOAS surgery with short-term mechanical ventilation on 100 per cent oxygen. The patient also presented histamine release signs after administration of amoxicillin clavulanate.
