Hematology and biochemistry results serve as an important part of the minimum database for all veterinary patients. Use three videos on blood collection in lizards, snakes, and chelonians (or text with still images) plus one slideshow on general principles to better understand reptile venipuncture and to improve your ability to obtain a clinically useful sample. This teaching module is approved for 1 hour of continuing credit for veterinarians and veterinary technicians by the American Association of Veterinary State Boards Registry of Approved Continuing Education.
Successful venipuncture can be a challenge in turtles and tortoises, however hematology and biochemistry results serve as an important part of the minimum database in chelonians just as they do for all veterinary patients. Use this video, or text with still images, to review the equipment needed and sample handling recommendations as well as the potential complications and proper approach to the jugular vein, brachial vein, subcarapacial vessel, and dorsal coccygeal sinus in the chelonian.
Hematology and biochemistry results are an important part of the minimum database for all veterinary patients, including lizards. Proper venipuncture technique is critical for accurate interpretation of laboratory results. Blood samples are most frequently collected from the ventral coccygeal vein and jugular vein in lizards; however, the site selected can depend on a variety of factors including the preferences and experience of the phlebotomist, the volume of blood needed, patient size and temperament, and of course the species involved.
Proper patient handling, blood collection technique and sample handling are all critical for accurate interpretation of hematology and biochemistry in all patients, including snakes. Use the video or text with still images to review equipment needed as well as the potential complications and proper approach to the ventral coccygeal vein and the heart, the two most common venipuncture sites in the snake.
John Chitty BVetMed CertZooMed MRCVS presented a live, interactive webinar on the unique features of this group of terrestrial Chelonia and how these adaptations to a unique biome affect husbandry and disease investigation. This presentation provides an overview on identification and sexing, captive husbandry, hibernation needs and management, reproduction and follicular stasis, clinical investigations, hospitalization needs, and disease prevention.
Dr. Jaime Samour presented Part 1 (medical and nursing procedures) of his presentation for the Avian, Wildlife & Exotics club at the University of Tennessee College of Veterinary Medicine, and Part 2 (cosmetic procedures) for Mississippi State University. These distance-learning events were hosted by the Lafeber Company Student Program.
View the RACE-approved webinar recording, presented by Douglas Whiteside, DVM, DVSc, DACZM, DECZM (Zoo Health Management). Topics covered include clinically relevant anatomy and physiology, obtaining a detailed history, triage and emergency therapies, clinical examination, diagnostic testing, analgesia, nutritional support, hospitalization, and euthanasia.
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.
Blood collection in miniature pigs can be a challenge. Peripheral veins are not readily accessible and some vessels, such as the auricular vein, are inadequate for obtaining sufficient volumes. The radial vein is located along the medial aspect of the forelimb. This vessel is relatively straight and generally superficial.
The term “miniature pig” is used to describe a variety of smaller pig breeds as well as crossbreeds. There are at least 14 recognized breeds of miniature pigs, including the Vietnamese potbellied pig, the Juliana pig, the KuneKune, and others. This information sheet reviews natural history and taxonomy, as well as a number of clinically relevant information including (but not limited to) diet, housing, behavior, normal physiologic data and anatomy, restraint, preventive medicine, zoonoses, and important medical conditions seen in the mini pig.
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.
Hematology and biochemistry results serve as an important part of the minimum database for all veterinary patients. Although collection of blood samples can be a clinical challenge in reptiles, the method of patient handling, blood collection and sampling techniques are all critical for proper interpretation of laboratory results. This brief video or slideshow with still images reviews the basic principles of reptile venipuncture that should be considered before, during, and after the procedure.
Because of a lack of identified blood groups in companion bird species, compatibility for transfusion is based on the use of major and minor cross matches. A major cross match is performed by mixing donor red cells with recipient plasma and a minor cross match uses recipient cells and donor plasma. The appearance of agglutination or cell lysis indicates incompatibility.
Unlike mammals, a single transfusion between different bird species can be safe and efficacious. Transfusions will be most effective if the donor is…
Blood work is considered a basic diagnostic test in every species, including birds. Venipuncture may be indicated for wellness screening, sample collection for DNA sexing, evaluation of the ill or injured bird, as well as collection of blood for transfusion. The value of testing must always be weighed against the stress of venipuncture since the critically ill bird may not be stable enough for restraint. This article reviews equipment needed, the volume of the blood sample, general tips for blood collection, common venipuncture sites in the bird, and sample handling.
Although hematology and biochemistry are an important part of the clinical picture in the avian patient, this bloodwork remains just ‘part of the picture’. All too often, when a clinician is unfamiliar with a species, the reaction is often to rely on laboratory results to hang a diagnosis upon. Although we have all been guilty of this, such an approach is inappropriate. For each sick bird, the following diagnostic tools should be applied: complete history, visual examination of the bird and its environment, physical examination, clinical pathology sample collection (blood, feces, swabs, aspirates, etc.), and radiography.
White blood cells are similar to mammalian lines, except that mammalian neutrophils are replaced with heterophils and mammalian platelets are replaced with thromobocytes. There are significant variations in normal differentials among avian species, in particular the total white cell count and…
Regardless of the initial cause of illness or injury, neonatal psittacine birds often develop secondary bacterial and/or fungal infections that can become serious primary problems. These infections are most commonly encountered within the gastrointestinal tract.
Hemochromatosis, “iron overload”, or “iron storage disease” is the excess accumulation of iron within parenchyma, especially in the liver and eventually in the heart and spleen. Elevated iron stores eventually lead to hepatocyte damage and fibrosis.
Blood collection is challenging in sugar gliders. Heavy sedation or general anesthesia, using isoflurane or sevoflurane, is almost always required in clinical practice. The most common sites for blood collection in the glider are the jugular vein and the…
Blood collection is challenging in rats and mice, and heavy sedation or general anesthesia is almost always required in clinical practice. Increasing patient body temperature to promote vasodilation can also be helpful. Gently warm the rodent by placing its cage on a heating pad set on low or by placing the cage in an incubator set at 39°C (102°F) for 5 to 10 minutes. Monitor the patient carefully…
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.
Hemorrhage in the critical patient can occur from a number of reasons. Before a blood sample is collected, carefully weigh the risk to the exotic animal patient against the clinical value of the test results. What will you do with this information? How will it affect your clinical plan? EDTA is the most commonly used anticoagulant in small mammals; lithium heparin is commonly used in birds and reptiles. Whenever possible, make a blood film immediately after venipuncture using fresh blood free of anticoagulant. Most adult small mammal hematocrits range from…
All but the weakest ferrets can be challenging to restrain for blood collection. Consider sedation or general anesthesia, particularly if the handler or phlebotomist is relatively inexperienced; however remember that anesthesia can affect ferret hematology.
Use this video clip or article with still images to review equipment needed, and potential venipuncture sites including the jugular vein, cranial vena cava, lateral saphenous vein, and cephalic vein.
The rabbit has a relatively short prothrombin time and whole blood quickly clots at room temperature. To minimize the risk of clot formation, it can be helpful to pre-heparinize the needle and syringe by drawing heparin into the needle and expelling the excess from the hub. The total volume of blood that can be safely collected typically ranges from 0.5% to 1.0% body weight. Collect smaller volumes from geriatric patients or those suspected to have anemia or hypoproteinemia.
Use this video clip or article with still images to review equipment needed, and potential venipuncture sites including the jugular vein, lateral saphenous vein, and ear vessels.
Hematological and serum chemistry tests are considered part of the minimum database, yet collecting blood samples from small mammals can be extremely challenging. This review article reviews the recommended venipuncture site in popular exotic companion mammals including many rodents, rabbits, ferrets, hedgehogs, and sugar gliders. Sample collection from peripheral vessels including the cephalic, saphenous, tail, jugular, ear, and submandibular vein is discussed.
Blind venipuncture sites such as the cranial vena cava and femoral vessels are also described. Veterinary health professionals are also acquainted with the potential risks associated with blood collection from these small species, especially those presenting in advanced diseased states. Tips for clinical success are also shared.
Small mammals, such as rabbits and rodents, are stoic by nature and have evolved to mask their illness to avoid predation. This behavior can create a false sense of security in owners and a clinical challenge for veterinarians. In some cases, an animal that appears clinically normal may in fact have a terminal illness. Use hematology and biochemistry analysis to characterize the true physiological status of these species and aid in disease diagnosis.
The African pygmy hedgehog is a native of West and Central Africa. When threatened, the hedgehog curls into a ball, extends its spines, puffs up, and hisses. When exposed to a new object, hedgehogs may exhibit “self anointing” or “anting”. The new object is licked until thick, frothy saliva collects and is then…
