Dr. Lorenzo Crosta will present this live, interactive, webinar on the clinical perspectives of avian anesthesia. After briefly reviewing clinically relevant avian anatomy and physiology, Dr. Crosta will touch upon injectable anesthesia, then discuss in detail preanesthesia and inhalation anesthesia in clinical practice. The discussion will then move onto monitoring the avian patient, from vital parameters to capnography, doppler, electrocardiography, and pulse oximetry. Dr. Crosta will also discuss analgesia, intra-operative fluid therapy, as well as specific concerns related to avian anesthesia, such as positioning the patient, hypocalcemia, air sac cannulation, as well as management of diving birds. This seminar will conclude with practical tips for safe and uneventful patient recovery.
Dr. Heather Barron presented this webinar on avian critical care. View a recording of the live, interactive event, then take the brief post-test to earn 1 hour of continuing education credit. The goal of wildlife medicine is always eventual release and therefore triage of avian wildlife may vary based on case load, regulations, and the presenting situation. Dr. Barron examines the guidelines used to set triage policy and the reasons a bird may not be releasable or have a good quality of life in captivity. She then discusses practical measures intended to alleviate suffering and improve the odds of patient survival, such as fluid support, analgesia, evaluation of blood volume, and transfusion. This presentation concludes with a brief discussion on assessing life and euthanasia.
Long-term vascular access is difficult to obtain and maintain in chelonians. Fortunately, central venous catheters provide flexibility and length to avoid catheter dislodgement. Central lines are an effective tool that allow serial blood measurements and can be used for anesthesia administration, intravenous drug delivery, blood product transfusions, and continuous fluid therapy or continuous rate infusions.This photo tutorial article describes this simple technique step-by-step.
This free, R.A.C.E.-approved continuing education webinar, Emergency and Critical Care of Rabbits, was presented by Charly Pignon, DVM, DECZM (Small Mammal) on November 7, 2018. Lecture topics of this webinar recording include emergency triage, cardiopulmonary resuscitation, analgesia, fluid therapy, and critical care nutrition.

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.
This learning aid is designed to assist the participant in meeting the needs of VECCS-certified facility. The basics of emergency medicine and critical care universal, however veterinarians face a unique set of challenges when caring for birds, exotic companion mammals, and reptiles. Level 1 of this teaching module reviews the basics of exotic animal critical care. To learn more in Level 2, review the key points on critical care or supportive care for each taxonomic group: birds, exotic companion mammals, and reptiles. Each summary page includes a brief quiz that tests your knowledge and reinforces fundamental principles. Delve deeper into critical care of exotic animal patients in Level 3 by browsing pertinent exotic animal content on LafeberVet.
Reptiles lack an epiglottis and the glottis is ready visualized, making intubation readily accomplished in most species. If the glottal folds are closed, apply topical lidocaine to facilitate intubation. The tracheal rings are complete in reptiles. Use of an inflated, cuffed endotracheal tube can lead to pressure necrosis because there is no elastic ligament to accommodate tracheal expansion. Always select an uncuffed endotracheal tube in small reptiles and never inflate a cuff in large reptiles …
Although the principles of emergency medicine critical care are universal for all species, this approach must be balanced with an understanding of the unique aspects of small mammal medicine. Use this summary page to review the basic approach to the exotic companion mammal patient and select additional links to supplement your knowledge base.

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.

This webinar explores five common reptile clinical presentations in detail: trauma, gastrointestinal foreign body, neurological deficits, respiratory difficulty, and reproductive problems.
Placement of an enteral feeding tube is a recognized method of supportive care, and the esophagostomy tube is an accepted route that is generally well tolerated by avian patients and relatively easy to place. In clinical patients, esophagostomy tube placement has been described in psittacine birds, raptors, and ostriches.
Esophagostomy tube placement is indicated in cases of severe beak trauma or disease, as well as diseases of the oral cavity or proximal esophagus, such as abscesses and neoplasia. Esophagostomy tubes may also be used to…
Many people have been curious about the way we at International Bird Rescue were able to clean the birds affected by the San Francisco Bay Mystery Goo Spill in January 2015.
Traumatic orthopedic injuries are relatively common in the avian patient. Although bird bones are strong when intact, they tend to shatter on impact as the cortices are thin and brittle. A lack of abundant soft tissue coverage often leads to open fractures…
All raptors consume a meat-based diet ranging from the specialist diet of the fish-eating osprey (Pandion haliaetus) to a generalist diet that can include insects, mammals, birds, reptiles, amphibians, and even carrion. Other than poultry, the exact nutritional requirements of birds are unknown, however the natural raptor diet is always relatively high in protein and fat and low in carbohydrates. Whole prey diets have a calcium/phosphorus ratio of 1.5:1 as the bird actually consumes the bones as well as the meat…
Did you attend the Lafeber Symposium at the 2015 International Conference on Avian heRpetological and Exotic mammal medicine in Paris? View a recording of this encore, web-based seminar: “Medical Management of Psittacines with Bornavirus Ganglioneuritis (PDD)” by Susan Orosz, DVM, DABVP (Avian Practice), DECZM (Avian). This presentation on avian borna virus contains medium to advanced level content. The novice is encouraged to view the first hour of Dr. Orosz’s presentation “Anatomy & Physiology of the Avian Gastrointestinal Tract: Clinical Applications”, which includes a helpful review of avian gastrointestinal anatomy and physiology.
The use of esophagostomy tubes (E-tubes) allows administration of oral medications and critical care nutrition to turtles and tortoises while minimizing stress and the risk of esophageal trauma associated with repeated rigid gavage tube feeding. Esophagostomy tubes are very well tolerated in chelonians and the patient can even eat normally with the tube in place. Patients can be medicated and fed on an outpatient basis, and once fully recovered, the E-tube is easily removed in the veterinary clinic.
Released for National Veterinary Technician Week 2014, Nursing Care for Exotic Companion Mammals is part of an Exotic ICU series providing advice on the management of small exotic companion mammals in a critical care setting. Specific recommendations on caging, medicating, feeding, and monitoring the critical small mammal are explored as well as important potential sequelae to the stress of hospitalization.
It is 10 p.m. in your veterinary emergency hospital and a dreaded call comes in. A panicked owner is in tears because their beloved pet is in crisis. In most cases, your team will quickly gather supplies and move swiftly to prepare for the emergent patient. This patient may strike fear in many veterinary professionals, however, because it is the dreaded avian patient presenting to a general veterinary practice.

Wing injuries may present as a wing droop or an inability to fly. The figure-of-eight bandage, or wing wrap, is the standard method for stabilizing the wing short-term. See the NEW and improved version of LafeberVet’s wing wrap placement video clip.
If the gut works, use it. The preferred route for providing nutrition is enteral feeding since this preserves intestinal structure and function. Parenteral nutrition is indicated to prevent malnutrition when patients cannot consume adequate nutrients by oral feeding or tube feeding or when the respiratory tract cannot be protected. Parenteral nutrition is 100% bioavailable since nutrients reach tissue without the variations associated with gastrointestinal digestion.
Providing nutrition to the hospitalized small mammal is a fairly straightforward process. Encourage owners to bring their pet’s “regular” diet to minimize the risk of food refusal or gastrointestinal upset. Also consider keeping the following food items available…
Depending on their age and size, snakes may be fed multiple times in one week or every 2 to 4 weeks. If nutritional support is truly needed, then assisted feeding is indicated in the hospitalized snake. Tube feeding is commonly performed in critically ill snakes after fluid therapy and supplemental heat is provided.
This brief article was created to serve as a synopsis of LafeberVet’s longer, more detailed “Avian Analgesia” authored by avian veterinarian, Dr. Michelle Hawkins.
The principles of fluid therapy are basically the same in exotic companion mammals as in other species. The biggest difference is that changes can occur very rapidly in these tiny patients. For instance, fluids should almost always be warmed or your patient will cool down quickly. Intraosseous or intravenous fluids can be heated with…
Turtles and tortoises display a variety of dietary strategies ranging from the complete herbivory seen in many tortoises to the strict carnivory displayed in aquatic species like the snapping turtle. There are also many chelonians, such as the Eastern box turtle, that may be considered opportunistic omnivores. This review article, critiqued by reptile nutritionist, Susan Donoghue, discusses clinical concerns related to feeding the hospitalized turtle or tortoise. Topics covered range from recognizing true anorexia to food items to avoid. Practical technical concerns related to nutritional support such as tube feeding and daily caloric requirements are also discussed.
Abdominocentesis or coelomocentesis may be indicated for the accumulation of fluid within one or more of the peritoneal cavities. Peritoneal fluid can accumulate with a variety of diseases, including chronic liver disease, amyloidosis in waterfowl, iron storage disease in mynah birds and toucans, coelomic tumors in budgerigar parakeets, viral infections like Marek’s disease (resulting in cardiac tumors), peritonitis, congestive heart failure, ovarian cysts, and trauma. This article reviews the potential complications of this clinical technique, the equipment needed, sample handling, and cytodiagnosis.

Fasting may be expected in lizards during certain times of the year. Many gravid females eat less or go off feed entirely due to the large number of eggs filling the coelom. Some species also fast for weeks or months as an adaptation to excess heat or cold, drought, or lack of food. This dormancy in reptiles is called…
Exotic animal practice is challenging! To approach any exotic animal patient requires a balancing act between the principles of “One Medicine-One Health” and species-specific information. The basic principles of avian medicine are the same as for a human being or a horse or a cat or a dog, and in many instances, veterinary care of birds may be extrapolated from basic medical principles. However this approach can only take one so far and these basic principles must be weighed against species-specific information.
The basic principles of fluid therapy are the same in the reptile as seen in birds and mammals, however reptile anatomy and physiology make some features of this crucial supportive care procedure unique. This article reviews fluid resuscitation with the use of crystalloid fluids and colloids, indications for replacement fluids including signs of dehydration and osmolarity values reported in reptiles. Routes of fluid administration in reptiles are described include subcutaneous, oral, soaking, intracoelomic, intraosseous, and intravenous via the cephalic vein, jugular vein, and in rare instances intracardiac catheter placement. Patient monitoring, including blood pressure measurement and signs of overhydration, are also explored.
When planning to accept avian patients, prepare yourself and your staff, prepare your hospital including hospital caging and exam rooms, and consider the equipment necessary for proper care…
The crop or ingluvies is a diverticulum of the esophagus present in many but not all, bird species. The crop serves as a food storage organ, regulating the flow of food through the gastrointestinal tract. Food within the crop is also softened by mucus glands. Crop stasis is a common clinical sign in which the crop fails to empty in a timely manner…
“Normal Body Weights in Birds” is a collection of normal reported weights in common companion birds and birds of prey presented in table format. Keep in mind that reported normal body weights for a given species can vary significantly…
Most amphibians do not drink water. Fluid instead diffuses across semipermeable skin, and sometimes gills, directly from water or moist substrates. Excess fluid is excreted primarily by the kidneys, while conserving electrolyte levels. In some amphibians, skin is also involved in osmoregulation and respiration.
Water is the single most important medium for sustaining life. Although there are unique considerations for avian, exotic companion mammal, and reptile patients, the basic principles of fluid therapy hold true for all animals. This brief article reviews 10 important facts related to water and organ homeostasis.
Physical examination parameters used to assess hydration are essentially the same in birds and mammals. Reduced elasticity of the skin or decreased skin turgor is seen with dehydration however normal bird skin is relatively inelastic and checking skin turgor is not as straightforward as in mammals. To check skin turgor in birds, tent the skin on the on the…
No single hospital environment can meet the needs of every exotic animal and caging systems must be tailored to meet the specific needs of each patient. Read about those caging requirements that remain constant among exotic animals as well as the species-specific needs of each taxa from birds and small mammals to fish, amphibians, and reptiles.
Among exotic animals, venous cutdown is most commonly employed in reptiles like lizards and snakes although intraosseous catheters are also placed in lizards. Similarly, when an exotic companion mammal like a ferret or rabbit suffers from severe hypovolemia, dehydration, hypotension, and vascular collapse, intraosseous catheters have largely replaced venous cutdowns but this technique is occasionally employed.
Why syringe fed? A cornerstone of treatment is delivery of food containing high dietary fiber. Proper syringe-feeding technique is essential..
Keeping your pet healthy is everyone’s goal. However if your bird becomes ill, effective treatment will require that medications are given at the right dose and frequency for the…
Due to their unique anatomy, physiology, and behavior, critically ill reptiles pose special challenges. Fortunately there are a host of tips and tricks that can increase clinical success in an intensive care setting.
At the Ontario Turtle Conservation Centre, previously the Kawartha Turtle Trauma Centre, we encourage private practices, emergency clinics, and rehabilitation centers to aid in the initial treatment of these injured turtles. We admit turtles from across the province, and it is extremely beneficial to the turtle to get immediate care locally before transfer. Snapping turtles are incredible in their ability to heal (albeit slowly!) and we cannot stress enough that the injuries can appear horrific, and yet can go on to heal, with subsequent release of the turtle back into the wild…
Debilitated sea turtles are often too weak to be housed in water upon presentation to a veterinary medicine or wildlife rehabilitation setting. Instead these patients are maintained on a padded surface or waterbed. Once the turtle is stronger, it should ideally be transferred to a rehabilitation tank. LOGIN to view references.
Fluid therapy is an important part of supportive care, and there are several routes available for fluid support in the reptile. Subcutaneous and/or oral fluids are appropriate for mild to moderate dehydration, while intracoelomic, intravenous, or intraosseous fluids are administered to critically ill reptiles or to patients with moderate to severe dehydration.
In My Experience: Living with a PDD Bird was authored by a diligent parrot owner and reviewed by her avian veterinarian. This commentary includes suggestions on diet as well as management tips that improved the quality of life, and possibly the life span, of this owner’s birds.
Do you have everything? Shared by registered veterinary technician and veterinary technician specialist, Jill Murray of Oklahoma State University, review our collection of procedure equipment checklists. Checklists are used in clinical practice to make preparation for procedures more efficient and more consistent, thereby improving the quality of care. Use these equipment checklists to train students and staff, or simply to jog your memory for procedures performed only sporadically.
Esophagostomy tube placement is an excellent choice for nutritional support of the debilitated small mammal patient requiring long-term feeding or for individuals that have suffered major orofacial trauma. Use this video clip or text with still images to review this important technique in the ferret.
Intravenous catheters are commonly placed in ferrets and rabbits to administer fluids and medications, induce anesthesia, and for delivery of analgesic drugs during and after surgery. Intravenous catheters are also placed with growing frequency in chinchillas, guinea pigs and other small exotic companion mammals. Use this video clip or text with still images to review patient selection, potential complications, equipment needed and step-by-step instructions for this technique, as well as daily fluid requirements, catheter maintenance, and patient monitoring.
Nasogastric tube placement in the rabbit is an excellent choice for the weak, dehydrated patient that requires enteral nutritional support. Use of a nasogastric tube can be less stressful and more successful than syringe feeding. Nasogastric intubation is also indicated in rabbits that will undergo surgery involving the oral cavity, esophagus, stomach, or biliary tract. Use this video clip or text with still images to review contraindications and potential complications, equipment needed as well as the technique involved.
Waterfowl that require hospitalization may come from a variety of settings, however the basic approach to waterfowl patients remains the same. When hospitalizing any waterfowl patient, there are a number of basic facts to keep in mind…
Intravenous catheters are commonly placed in rabbits to administer fluids, medications, induce anesthesia, and for delivery of analgesic drugs during the perioperative and postoperative periods. Catheterization techniques used in dogs and cats can also be used for rabbits. To reduce the time in handling and reduce stress, supplies needed for catheterization should be set out and ready to go, prior to removing the patient from the cage.
Fluid therapy is a vital part of avian medicine, and appropriate administration of fluids is essential. Intravenous catheters are commonly used intraoperatively or in more stable hospitalized patients. Unfortunately intravenous catheter placement in birds can be challenging. The veins can be difficult to access and the vessels are also prone to hematoma formation.
Use this video clip or text with still images to review the equipment needed, the technique involved, and potential venipuncture sites including the jugular vein, medial metatarsal vein and basilic or ulnar vein.
Loss of appetite is a common finding in the sick ferret and nutritional support is often required. Ferrets with insulinoma may also require regular assist feedings to help maintain normal blood glucose levels. Fortunately syringe feeding the ferrets is a relatively straightforward process. The short, simple gut of the ferret has only a limited ability to absorb nutrients. So even healthy ferrets require a highly digestible diet. Use this video or article to review the equipment needed and the technique involved.
Mild to moderately ill exotic companion mammals are often syringe fed, and proper syringe-feeding technique is an essential skill for critical care nutrition of ferrets, rabbits, and rodents. Gastrointestinal stasis is one of the most common medical problems seen in small herbivores. A cornerstone of treatment is delivery of food containing high dietary fiber. Aggressive fluid therapy, often in the form of oral and subcutaneous fluids, is also crucial for successful management. Always address dehydration before beginning nutritional support. Get specific tips to improve your clinical success with this video clip or read the article with still images.
The subcutaneous route is the most common method of fluid administration in the avian patient. Subcutaneous fluids are an excellent way to provide maintenance fluids or to correct mild dehydration in birds. This video clip and article with still images describe the equipment needed and the technique involved in this supportive care procedure.
Fluids are most commonly given in the inguinal space (crural patagium). With the bird secured by an assistant, have them extend one of the bird’s legs out and to one side. Wet down the area on the inner thigh to see the skin better at a point about halfway between…
Fluid therapy is indicated in critical patients including exotic animals. Vascular access can be extremely difficult or even impossible during shock, making intraosseous or IO catheterization necessary in the bird. Fortunately fluids and medications given through IO catheters are immediately taken up into the vasculature. The distal ulna is the site of choice for intraosseous catheter placement in the bird.
Fluid therapy is an important part of supportive care in the critical patient. When intravenous catheter placement fails or when veins are too small or too fragile, an intraosseous or IO catheter is an excellent option in exotic companion mammals. Use this video or text with still images to review equipment needed, potential complications, as well as the technique for intraosseous catheter placement in small mammals.
Tube feeding, also known as gavage feeding, is an essential part of avian supportive care. Sick birds are often presented with a history of anorexia and glycogen stores may be depleted within hours in small species with relatively high metabolic rates. Another important indication for gavage feeding is a documented drop in body weight of 5% to 10%.
Emeraid Omnivore can be hand fed or gavage fed to companion birds like parrots and songbirds and to omnivorous rodents like rats and mice. Emeraid Omnivore may be fed in combination with Emeraid Herbivore, to species like gerbils, hamsters, and the African pygmy hedgehog (Atelerix albiventris). Combinations of Emeraid Omnivore with Emeraid Carnivore can be used to meet the dietary requirements of these species…
Nutritional support is indicated in reptiles with a 10% drop in body weight, and force-feeding is sometimes indicated with a history of anorexia. Interpretation of anorexia can be difficult in some reptiles, particularly snakes and chelonians. Never rush to feed a reptile. The patient must first be warm, housed at its preferred optimal temperature zone, and must be adequately hydrated.
Pain assessment in birds is very complex because it requires consideration of differences in age, gender, species, individual behaviors and environmental factors. Birds may exhibit different behaviors or may hide painful behaviors when outside of their home cage. Predatory species may exhibit painful behaviors more readily than prey species. Many clinical signs may be associated with pain in birds including…
Small birds face an enormous task in maintaining their body temperature, especially in a cold environment, but fortunately plumage provides an effective barrier to heat loss. Down feathers trap air and allow little convective movement of heat to occur. Fluffing feathers increases insulation and…
