A dedicated anesthetist should be assigned to monitor every patient during the perianesthetic period. The anesthetist is fundamental to patient safety because she assures the patient is not aware, not moving, and not in pain, all while maintaining stable anesthetic depth. A deep plane of anesthesia can lead to hypoventilation and hypoxemia, reduced cardiac output, hypotension, inadequate tissue perfusion, central nervous system (CNS) depression, and prolonged recovery. This review article first explores the stages of anesthesia and then discusses assessment of anesthetic depth in exotic companion mammals, birds, and reptiles.

Capnometry measures the maximum value of carbon dioxide (CO2) obtained at the end of expiration or end-tidal carbon dioxide (ETCO2). There is good correlation between ETCO2 and arterial CO2 in birds and mammals and capnography can be used as a reliable tool to evaluate the adequacy of ventilation in these species. Capnography can only be used to identify trends in reptiles because of cardiac shunting of blood past the reptilian lungs.

Article

Even the most steadfast and seasoned veterinary anesthetist can find themselves intimidated by exotic animal patients. Standard veterinary anesthesia monitors are not designed to read the extremely high (or extremely low) heart rates and respiratory rates of some exotic animal patients. Despite these challenges, valuable information can be gathered from monitoring tools as well as hands-on techniques. Essential vital signs, such as heart rate and rhythm, respiratory rate and depth, body temperature, and mucous membrane color should all be evaluated.

There is little empirical information available on cardiopulmonary resuscitation in most exotic animals. Fortunately, the basic principles of CPR are the same for all species, however there are important species-specific considerations. This review article explores techniques for establishing airway control, ventilation and cardiac compression recommendations as well as considerations for emergency drug selection.

Article

The approach to analgesia and sedation in exotic companion mammals faces special challenges, including small patient size and unique features of the prey species mentality. Recognition of pain is more difficult in rabbits and rodents because many small mammals are very good at hiding the signs of pain commonly observed in predator species. Instead pain in a rabbit or rodent is often inferred from the patient’s clinical condition as well as the absence of normal behaviors. The diagnostic and therapeutic plan frequently requires some form of chemical restraint in exotic mammal medicine. When compared to general anesthesia, sedation is a safer option for the debilitated or critically ill small mammal.

Article

Rabbit intubation can be accomplished using either an orotracheal or nasotracheal technique. Both intubation methods can be challenging in rabbit patients and require patience and practice. Nasotracheal intubation may be the preferred approach in situations where maximum access and maneuverability is required in the oral cavity. Nasotracheal intubation is also preferred where an extended recovery is expected.

Air sac cannulas are routinely used to ventilate birds by a route other than endotracheal intubation. Air sac tubes are used for oxygenation and anesthesia, especially during surgery of the head or trachea where tracheal intubation would be cumbersome. In addition, air sac cannulas provide a means to medicate air sacs directly, and they are also used to aid dyspneic birds with tracheosyringeal obstruction from foreign bodies, granulomas, or tumors.

In no way, should the reader believe the use of tracheostomy tubes is common in exotic companion mammals like the guinea pig. This technique is exceedingly rare. However given the frequent lack of airway control and the particular concerns when anesthetizing guinea pigs, those concerned with emergency and critical care should be aware of this technique as a “back up” option. In most instances, use of this surgical approach would mean that the clinician has failed to exercise foresight and planning for their patient’s airway control. Nevertheless anyone who sees rodents, particularly on an emergency basis, should consider compiling a tracheostomy kit and practicing this technique on cadavers.

Are you using epidurals in your practice? The epidural is a neuroaxial technique that provides preemptive analgesia by injecting drug into the epidural space surrounding the spine. Epidurals can be used for abdominal surgery, perineal surgery, and orthopedic procedures involving the pelvic limb or spine. Some opioids can also travel cranially to provide supplemental analgesia for chest and thoracic limb procedures. Epidurals serve as an adjunct to systemic analgesia, and epidural analgesia also reduces the amount of anesthetic drug needed. Epidurals can also shorten recovery time.
