Institution of appropriate, timely nutritional support in the anorexic or critically ill patient has become accepted medical practice in people and animals. This article focuses on the benefits of appropriate nutrient intake in critically ill animals, recommended nutrient requirements for dogs and cats receiving enteral feeding, and mechanics of food preparation and delivery for a variety of feeding tubes. General nutrient requirements for all patients, specific recommendations for certain illnesses such as renal failure, pancreatitis, and hepatic disease, and nutritional alterations for critical illness are reviewed. Commercial liquid diets manufactured for people and pets, and pet-food diets practical for formulation of gruel are presented. Institution of and weaning from feeding are explained. 相似文献

Nutritional support in critical care patients. 总被引：3，自引：0，他引：3
Rebecca L Remillard 《Veterinary Clinics of North America: Small Animal Practice》2002,32(5):1145-64, viii
Malnutrition in the form of insufficient nutrient intake to support tissue metabolism undermines appropriate medical or surgical therapeutic management of a case. The major consequences of malnutrition in all patients are decreased immunocompetence, decreased tissue synthesis and repair, and altered intermediary drug metabolism. A practical goal is to begin nutritional support within 24 hours of the injury, illness, or presentation. There are only two methods by which nutrients can be supplied to the body: enteral and parenteral. General guidelines are presented to help establish a foundation. 相似文献

Objectives – This case series describes 5 dogs with small intestinal intussusception and acute kidney injury due to infection with Leptospira interrogans serovar Australis.
Case Series Summary – Small intestinal intussusception was observed in 4 dogs diagnosed with acute kidney injury due to leptospirosis presented between 1997 and 2005. Intussusception was diagnosed at initial presentation or later during hospitalization. An additional dog fulfilling our inclusion criteria was presented to a small animal specialty clinic nearby and was included. Upon admission, all dogs were severely azotemic and thrombocytopenic. All 5 dogs showed the strongest microscopic agglutination test serology reaction to L. interrogans serovar Australis. Two dogs survived with no apparent residual renal damage, 1 survived with subsequent mild chronic kidney disease, and 2 dogs were euthanized at the owners' request due to a guarded prognosis.
New or Unique Information Provided – Intussusception can occur or may be seen in dogs with leptospirosis due to L. interrogans serovar Australis and patients should be monitored closely for this potential complication. As all 5 dogs described in this case series showed the highest titer for L. interrogans serovar Australis, these precautions may be especially applied in geographic areas where this particular serovar is seen. 相似文献

This position paper delineates the expert recommendations of the Regulatory Affairs Committee of the American Society for Veterinary Clinical Pathology for the use of preclinical, clinical pathology endpoints in assessment of the potential for drug-induced hepatic injury in animals and humans. Development of these guidelines has been based on current recommendations in the relevant preclinical and human clinical trial literature; they are intended to provide a method for consistent and rigorous interpretation of liver-specific data for the identification of hepatic injury in preclinical studies and potential liability for hepatic injury in human patients. 相似文献

Behavior patterns exhibited by the domestic ferret, although similar to its wild cousins, are distinctly domestic in nature. Domestic ferrets use many different types of behaviors, including body posturing, animations, vocalizations, and scent markings. These behaviors may differ somewhat from ferret to ferret. The domestic ferret is best understood by observation and recognition of its behavior patterns and interactions as it plays and communicates with both humans and animals within its home environment. As with all other species of animals kept as pets, the clinician will be greatly benefited by urging the pet owner to regularly note typical behavior patterns for their individual pet. Following is a brief summary of behavioral changes noted in domestic ferrets that may aid the owner or keeper in the detection of potential illness or injury: A normally active ferret suddenly becoming quiet or vice-versa Any sudden increase or decrease in daily food and water intake Routine behaviors performed out of context or order, especially in older animals Any sudden increase or decrease in the speed at which routine behaviors are performed (such as urination, defecation, grooming, food, or water intake) Any sudden increase in the effort required to perform normal or routine behaviors Any sudden changes in personality or attitude toward other ferrets or toward other animals or people. The previous information was gathered over the last 15 years from personal observations, experiences, and studies of ferrets in the shelter, home, and animal hospital environments. This information regarding ferret behavior can assist the veterinarian in differentiating between normal and abnormal behaviors in domestic ferrets. This increased understanding of ferret behavior can aid in the diagnosis of injury and disease and assist the veterinarian in educating clients regarding ferret behavior, care, and recognition of potential disease. 相似文献

Elevated concentrations of serum phosphate are linked with progression and increased case fatality rate in animals and humans with chronic kidney disease. Elevated concentrations of serum phosphate can be a risk factor for development of renal and cardiovascular diseases or osteoporosis in previously healthy people. In rodents, an excess intake of dietary phosphorus combined with an inverse dietary calcium : phosphorus ratio (<1 : 1) contributes to renal calcification. Renal injury also has occured in cats fed experimental diets supplemented with highly soluble phosphate salts, especially in diets with inverse calcium : phosphorus ratios. However, not all phosphorus sources contribute similarly to this effect. This review, which focuses on cats, summarizes the published evidence regarding phosphorus metabolism and homeostasis, including the relative impact of different dietary phosphorus sources, and their impact on the kidneys. No data currently shows that commercial cat foods induce renal injury. However, some diets contain high amounts of phosphorus relative to recommendations and some have inverse Ca : P ratios and so could increase the risk for development of kidney disease. While limiting the use of highly soluble phosphates appears to be important, there are insufficient data to support a specific upper limit for phosphate intake. This review also proposes areas where additional research is needed in order to strengthen conclusions and recommendations regarding dietary phosphorus for cats. 相似文献

Like humans, many companion animals experience a gradual decline in skeletal muscle mass and function during later years of life. This process, analogous to sarcopenia in humans, increases risk for morbidity and mortality. Periods of reduced activity due to injury or illness, followed by an incomplete recovery, can accelerate the loss of muscle mass and function. Emerging research from human studies suggests that moderate amounts of high-quality protein may attenuate the loss of muscle, while preventing accumulation of fat during periods of disuse. Whey protein is a consumer-friendly and readily available source of high-quality protein. It supports skeletal muscle maintenance during normal aging and may also provide anabolic support during periods of illness, injury, and recovery. Ongoing research efforts continue to refine our understanding of how protein quality, quantity, and meal timing can be optimized to support retention of muscle mass and function during aging. Priority research areas include supplementation with high-quality protein during illness/injury to stimulate anabolism by targeting molecular mechanisms that regulate skeletal muscle metabolism. 相似文献

Necropsy and culture results are presented for 269 consignments of imported birds (mainly psittacine and passerine species) examined between January 1977 and August 1980. Consignments were submitted for diagnosis of clinical illness or deaths occurring among these birds while they were in quarantine before entry into Canada. Enteritis and injury were the most frequent diagnoses. Pathogens or potential pathogens were isolated from 77% of consignments. Newcastle disease virus was isolated nine times, and Chlamydia psittaci was isolated once. Escherichia coli (from 113 consignments) and salmonellae (from 49) were the most common bacteria isolated, and reoviruses (from 22) and paramyxoviruses other than Newcastle disease virus (from 22) were the most common viruses. Salmonella typhimurium was the most common Salmonella serovar. Salmonella hadar was isolated from turkey poults imported from Great Britain. The possible public health significance of the role of imported birds in the introduction of exotic Salmonella serovars, or of serovars resistant to several antimicrobials is discussed. 相似文献

There have been very few clinical trials evaluating therapies for naturally occurring spinal cord injury in dogs and cats. This review describes the methods suitable for evaluating the behavioural recovery of animals with spinal cord injuries, in either a clinical or a laboratory setting. A list of commonly used methods for evaluating behavioural recovery in animals is provided, both in the clinical and laboratory setting; the tests, their limitations and benefits and specific recommendations for their use are also discussed in more depth. 相似文献

The number of canine and feline clinical diseases that may be manifested as ocular dysfunction continues to increase. Veterinarians are often presented with sick patients who also have eye disease. Conversely, animals are examined for eye disease that on closer inspection also have a systemic illness. A decision must be made; is there a relationship between the observed ocular and systemic problem, or are they separate morbid processes? If they are related, can the ocular signs be used to better define the systemic illness, chart its course, or establish a prognosis? It is hoped this article will aid the clinician in gaining a better perspective on the complex relationship between the eyes and systemic disease. 相似文献

Birds are often presented to the veterinarian with injury or disease that affects their ability to use one or both legs. Although in wild birds traumatic injuries usually involve the wing, captive birds especially falconer's birds, are usually presented with injuries to their legs. This article focuses on conditions affecting practice: birds of prey, and injured wild birds. The birds are presented with lameness or loss of use of the leg. The conditions described can be initiated by injury or by disease affecting an area other than the leg, such as the kidney or spinal cord, or they can be toxic or metabolic. 相似文献

Taste aversion learning in horses 总被引：1，自引：0，他引：1
The ability of ponies to learn to avoid a relatively novel food associated with illness was tested in three situations: when illness occurred immediately after consuming a feed; when illness occurred 30 min after consuming a feed; and when illness was contingent upon eating one of three feeds offered simultaneously. Apomorphine was used to produce illness. The feeds associated with illness were corn, alfalfa pellets, sweet feed and a complete pelleted feed. The ponies learned to avoid all the fees except the complete feed when apomorphine injection immediately followed consumption of the feed. However, the ponies did not learn to avoid a feed if apomorphine was delayed 30 min after feed consumption. They could learn to avoid alfalfa pellets, but not corn, when these feeds were presented with the familiar "safe foods," oats and soybean meal. Ponies apparently are able to learn a taste aversion, but there were constraints on this learning ability. Under the conditions of this study, they did not learn to avoid a food that made them sick long after consumption of the food, and they had more difficulty learning to avoid highly palatable feeds. 相似文献

Objective To describe clinical findings, ultrasonographic features and outcome of injury to the branches of insertion of the superficial digital flexor (SDF) tendon in horses.
Design Retrospective study of 14 cases.
Procedure Fourteen Thoroughbred horses with tendonitis affecting the branches of insertion of the SDF tendon were examined for lameness, location and amount of swelling, and the presence of other musculoskeletal abnormalities. The flexor tendons were assessed by ultrasonographic examination, and recommendations were made for management of the cases. Outcome was assessed by re-examination of some horses, direct communication with the owner or trainer, and examination of race records.
Results The lateral SDF branch was affected in 10 horses; the medial branch in three, and both branches in one horse. Two horses had concurrent injuries to the SDF tendon in the metacarpal region of the contralateral limb. Ultrasonographic findings included swelling of the affected SDF branch, peritendinous fluid accumulation, disruption of normal fibre alignment on sagittal scan, and variable loss of echogenicity. As healing occurred, there was return of normal echogenicity, but normal fibre alignment did not return completely and apparent adhesions formed between the affected SDF branch and adjacent structures. Seven of 10 horses which returned to their previous use were able to compete without further tendon injury. Recurrence of injury occurred in one case, and another two horses developed tendonitis in the metacarpal region. One horse was retired from racing but was able to compete at dressage without recurrence of injury. Two horses were retired for breeding without returning to training, and one horse was sold and lost to follow up but did not race.
Conclusion The prognosis is fair for return to previous use following injury to the branches of insertion of the SDF tendon in athletic horses. 相似文献

Objective – To review current information regarding the pathophysiology associated with traumatic brain injury (TBI), and to outline appropriate patient assessment, diagnostic, and therapeutic options. Etiology – TBI in veterinary patients can occur subsequent to trauma induced by motor vehicle accidents, falls, and crush injuries. Primary brain injury occurs at the time of initial impact as a result of direct mechanical damage. Secondary brain injury occurs in the minutes to days following the trauma as a result of systemic extracranial events and intracranial changes. Diagnosis – The initial diagnosis is often made based on history and physical examination. Assessment should focus on the cardiovascular and respiratory systems followed by a complete neurologic examination. Advanced imaging may be indicated in a patient that fails to respond to appropriate medical therapy. Therapy – Primary brain injury is beyond the control of the veterinarian. Therefore, treatment should focus on minimizing the incidence or impact of secondary brain injury. Because of a lack of prospective or retrospective clinical data, treatment recommendations for veterinary TBI patients are primarily based on human and experimental studies and personal experience. Therapeutic guidelines have been developed that center on maintaining adequate cerebral perfusion. Prognosis – Severe head trauma is associated with high mortality in humans and animals. However, dogs and cats have a remarkable ability to compensate for loss of cerebral tissue. It is therefore important not to reach hasty prognostic conclusions based on initial appearance. Many pets go on to have a functional outcome and recover from injury. 相似文献

Pet foods on the market that are contaminated or otherwise present a health risk to humans or animals may be subject to a recall under US Food and Drug Administration (FDA) regulations. Legally, all recalls are "voluntary," but there is little incentive for companies to refuse a request by FDA to conduct a recall. While the firm does the bulk of the work, FDA oversees all aspects of a recall to help ensure that violative product is swiftly removed from the market. A recent new federal law will require FDA to improve its abilities to detect outbreaks of pet food-borne illness, respond to a contamination incident, and communicate with industry and the public on the matter of recalls. Veterinarians play a key role in detecting and reporting pet food-borne illness. 相似文献

Calves with diarrhea often have small intestinal overgrowth with Escherichia coli bacteria, regardless of the inciting cause for the diarrhea, and 30% of systemically ill calves with diarrhea have bacteremia, predominantly because of E coli. Antimicrobial treatment of diarrheic calves should therefore be focused against E coli in the small intestine and blood, the 2 sites of infection. Fecal bacterial culture and antimicrobial susceptibility testing is not recommended in calves with diarrhea because fecal bacterial populations do not accurately reflect small intestinal or blood bacterial populations and because the break points for susceptibility test results have not been validated. Antimicrobial efficacy is therefore best evaluated by the clinical response of a number of calves to treatment, with calves randomly assigned to treatment groups. Amoxicillin, chlortetracycline, neomycin, oxytetracycline, streptomycin, sulfachloropyridazine, sulfamethazine, and tetracycline administered PO are currently labeled in the United States for the treatment of calf diarrhea. On the basis of published evidence for the oral administration of these antimicrobial agents, only amoxicillin can be recommended for the treatment of diarrhea. Dosage recommendations are amoxicillin trihydrate (10 mg/kg PO q12h) or amoxicillin trihydrate-clavulanate potassium (12.5 mg combined drug/kg PO q12h) for at least 3 days; the latter constitutes extra-label drug use. Parenteral administration of broad-spectrum beta-lactam antimicrobials--ceftiofur (2.2 mg/kg IM or SC q12h) and amoxicillin or ampicillin (10 mg/kg IM q12h)--or potentiated sulfonamides (25 mg/kg IV or IM q24h) is recommended for treating calves with diarrhea and systemic illness; both constitute extra-label drug use. In calves with diarrhea and no systemic illness (normal appetite for milk, no fever), it is recommended that the health of the calf be monitored and that oral or parenteral antimicrobials not be administered. 相似文献

Objective: To summarize the challenges to recognizing pain in critically ill patients, the rationale for treatment even in the absence of signs of pain, and the therapeutic options available in the intensive care environment. Etiology: Pain is one of many stressors challenging the critically ill patient, and may in turn be multifactorial in nature. Common causes include local and systemic inflammation, injuries, diagnostic and therapeutic procedures, immobilization, and thrombosis. Diagnosis: Critically ill animals with pain may not demonstrate overt behavioral or physiologic signs of distress. Therefore, pain must be assumed to be present for animals whose condition puts them at risk. Therapy: Currently available analgesic and sedative drugs and methods of delivery are described. Several useful analgesics and sedatives may be co‐administered as fluid additives to provide continuous therapy. Prognosis: There is growing evidence that the neuroendocrine stress response to severe injury or illness may become sufficiently intense to contribute to morbidity and mortality. Many therapeutic analgesic and sedation options provide good control of pain and stress, and in some circumstances this may improve the outcome of critical illness. 相似文献
