is enclosed within the oxygen tent, monitoring of mucous membranes, capillary refill time and pupil size and reaction are impeded. Therefore, other monitoring techniques should be imple- mented.
Oxygen Cage / Box
Oxygen cages are commercially available or can be homemade. Using a cage is a non-invasive and less stressful way to provide supplemental oxygen. It is necessary to have a ‘clear’ box so the patient can be visually assessed at all times.
Commercial oxygen cage
The commercial oxygen cage enables ‘pure’ oxygen to be delivered to the cage, eliminating the use of an anaesthetic circuit.
Home-made Oxygen Cage
This oxygen cage has been made from a plastic storage box.
Several sizes can be made
· · A hole was drilled at one end of the box to facilitate the placement of the oxygen source via the anaesthetic circuit.
· · Two holes are drilled at the other end of the box to facilitate removal of expired carbon dioxide.
· · Although, not as clear as the commercial anaesthetic cage, the patient can still be continuously observed.
· · These boxes can become quite hot and therefore careful monitoring should be implemented to prevent this.
· · When the lid is removed from the box the oxygen content will drop dramatically and need to be replenished when re-sealed.

Learning objective: Oral and maxillofacial disorders require general anaesthesia for appropriate treatment. Therefore, anaesthesia and pain management are crucial areas of veterinary dentistry. An analgesic plan including a multimodal approach should be in place during the peri-operative period and for several days to a week after hospital discharge and it includes local anaesthetic techniques performed preoperatively. Patients must be comfortable and relaxed in order
to provide comprehensive dental therapy. Although patients may be sedated deeply enough to tolerate local anesthetic blocks and dental procedures, sedation leaves the airway and lungs unguarded. An unguarded airway predisposes patients to aspiration pneumonia, both from regurgitation and from the water and debris associated with the procedure. Placement of an endotracheal tube is the safest way to protect the lungs. With an endotracheal tube in place, inhalant anesthesia is easily administered and becomes the best option for anesthetic maintenance in nearly every patient.
Anesthetic monitoring is significantly correlated with decreased morbidity and mortality. The following
vital parameters should be monitored during general anesthesia: Pulse oximetry which can be a challenge to monitor during anesthesia for oral procedures since the probe can be easily displaced, however it can be placed over the ears and paws. Mean blood pressure which
is particularly important in dogs and cats with chronic kidney disease. Respiration should be ideally monitored using a capnograph since monitoring of respiratory
rate does not provide information of the “quality of
the respiratory function” Body temperature should be maintained between 37 and 38°C and monitoring it is necessary to react on time and prevent hypothermia.
Most oral and maxillofacial disorders and therapies involve inflammation and tissue damage/trauma. Oral disease and associated pain is a welfare issue since
it impacts quality of life and nutritional status. Dental disorders cause pain suffering, alter behaviour and cause physiological signs of stress Pain management
is not only important from the ethical and welfare
point of view but also as a therapeutic strategy. Pain management is performed preoperatively preoperatively and and postoperatively. It involves use of anesthetic drugs, techniques and their combinations aiming to minimise postoperative pain and discomfort.
