Topic:Hospitalization
Hospitalization of horses involves the admission of equine patients to veterinary facilities for the diagnosis, treatment, and management of various medical conditions. This process is typically initiated when a horse requires intensive monitoring, specialized care, or advanced medical interventions that cannot be adequately provided in a non-clinical setting. Common reasons for equine hospitalization include surgical procedures, severe injuries, colic, respiratory disorders, and infectious diseases. During hospitalization, horses are monitored for vital signs, administered medications, and provided with supportive care tailored to their specific needs. This page compiles peer-reviewed research studies and scholarly articles that explore the protocols, outcomes, and advancements in the hospitalization of horses, providing insights into best practices and innovations in equine clinical care.
Risk factors for salmonellosis in hospitalized horses. A case-control study to identify risk factors associated with isolation of Salmonella was accomplished, using data from records of horses hospitalized in the period July 1971 through June 1982. Horses in which nasogastric tubes were passed were at 2.9 times greater risk of having Salmonella isolated, compared with horses that did not undergo this procedure. Horses treated with antibiotics parenterally were at 6.4 times greater risk, and those treated with antibiotics orally and parenterally were at 40.4 times greater risk of developing salmonellosis, compared with horses not receiving such tre...
Complications associated with left dorsal displacement of the large colon in the horse. Four horses operated on for left dorsal displacement of the large colon (LDDLC) had major intraoperative or postoperative complications. One horse was euthanatized during surgery because of extensive necrosis of the large colon. Three horses that were discharged after surgical correction of LDDLC were readmitted with signs of abdominal pain between 5 weeks and 13 months after surgery. Two horses had recurrence of LDDLC, and the third horse had an omental adhesion attached to and obstructing the pelvic flexure. The displacements were corrected, the adhesion was broken down, and the horses were ...
Cecal perforation in the horse. The case records of 23 horses with cecal perforation (CP) were reviewed. The horses averaged 4.5 years of age (6 weeks to 13 years) and included 9 intact males, 12 mares, and 2 geldings. Twelve of the horses were Standardbreds, 9 were Thoroughbreds, and 1 each, a Belgian and Morgan. The horses were allotted to 2 groups: group I-13 hospitalized horses in which CP occurred unexpectedly, and group II-10 horses with CP at the time of admission. The horses characteristically had been sick or affected with disease unrelated to the cecum. Sixteen horses had been given nonsteroidal anti-inflammatory d...
Salmonella shed by horses with colic. Salmonella was isolated from 13 of 100 colicky horses admitted to a referral hospital. Seven horses were shedding the microorganism at or soon after hospital admission. A unique serotype was introduced into the hospital by a horse not shedding Salmonella at admission. It was concluded that 8 horses were infected before admission. Whether the remaining 5 horses were infected before or after admission could not be determined. Salmonella senftenberg was the most commonly isolated serotype from colicky horses and from horses with salmonellosis that were not colicky on hospital admission during the...
Nutritional support of the foal during intensive care. Provision of adequate nutritional support to the sick neonatal foal is a vital part of intensive care; frequently, however, it is very difficult to accomplish. In this article, current recommendations concerning both enteral and parenteral nutrition are discussed.
Ileal impaction in the horse. Twelve cases of ileal impaction in the horse were reviewed. Clinical features of the disease included evidence of mild abdominal pain, reduced or absent intestinal sounds, rectally palpable distended small intestine, gastric reflux, and in the early stages, normal peritoneal fluid. Surgical correction of the impaction was accomplished in 10 horses. Of 8 horses discharged from the hospital, 7 returned to full function. It was concluded that the shorter the duration of colic before surgical intervention, the better the prognosis.
Clinical and radiographic findings in Corynebacterium equi pneumonia of foals. Thirty-nine foals with pneumonia were admitted to the Veterinary Medical Teaching Hospital at the University of California, Davis. Corynebacterium equi was recovered from each of them on bacteriologic culture of transtracheal aspiration specimens or lung specimens at necropsy. The foals were divided into 2 groups. Group I consisted of 20 foals that died because of C equi pneumonia and were subsequently necropsied. Group II consisted of 19 foals that were treated and discharged from the hospital. Radiography was performed on all foals. Clinical signs included increased respiratory rate, fever, ...
Inclusions in equine cytologic specimens. Inclusions and cellular changes were seen in cytologic specimens from 1 healthy horse, 6 horses hospitalized because of respiratory problems, and 1 horse hospitalized because of colic and hepatitis. Two bronchial aspirates contained detached ciliated cytoplasmic tufts and cytoplasmic inclusions characteristic of the specific degenerative process called ciliocytophthoria. These changes and inclusions resembled those seen in bronchial aspirates from human beings with parainfluenza virus infection. Four bronchial aspirates and 2 serous fluid specimens had nuclear inclusions resembling those seen ...
[Results of the surgical treatment of colic, represented by case material of 1983 from the Munich-Riem horse hospital]. The results of the ileus surgery in horses by a consistent performing of a known and standardised clinical and operative procedure are very good, provided that there are surgeons who have experience in abdominal surgery and that there is a co-operating team for the pre- and post-operative care.
[Postoperative wound infection in the horse]. A systemic investigation of wound infection in the horse after operative treatment of large wounds reveals that the age of the wound is of critical importance. The limit for an uncomplicated healing process lies around four hours. The duration of the operation itself is of little significance, the location of the lesion on the body of the horse, however, plays a major role. The pattern of isolated bacterial organisms is discussed in relation to the duration of hospital treatment. It is concluded that a systemic antibiotic therapy is of no value and that a local antibiotic therapy is only indic...
Case-control study of risk factors associated with isolation of Salmonella saintpaul in hospitalized horses. In an investigation of a 1981-1982 outbreak of nosocomial Salmonella saintpaul infection in hospitalized horses at the University of California Veterinary Medical Teaching Hospital in Davis, California, a case-control study was performed using data gathered from the records of 33 cases and 132 controls. Multiple logistic regression risk analysis was used to identify factors associated with isolation of the organism, controlling for the effects of other, possibly confounding variables. Horses receiving parenteral antibiotics were at 10.9 times greater risk of having S. saintpaul isolated than w...
Ulcerative colitis and protein losing enteropathy associated with intestinal salmonellosis and histoplasmosis in a horse. Ulcerative colitis, protein losing enteropathy and intestinal histoplasmosis-salmonellosis were diagnosed in a six-year-old Quarterhorse stallion. For six months before examination, the horse experienced a slow continual loss of weight. During the 17 day period of hospitalisation the horse developed progressive generalised oedema. On the 12th day of hospitalisation a severe profuse watery diarrhoea began; the horse was killed five days later.
Serratia spp infection in 21 horses. Twenty-three isolations of Serratia spp were made from 21 horses at the University of Florida Veterinary Medical Teaching Hospital between Jan 1, 1979 and July 1, 1983. Three Serratia spp were involved in single-organism and mixed infections of various tissues. Eight horses of this group died. All horses that died had massive, mixed, gram-negative infection. The other 13 responded to treatment, including systemic antibiotic therapy. Most of these horses were stressed and under antibiotic therapy prior to the time of culture. Possible nosocomial infection, variable antibiotic sensitivity, and a...
Ultrasonographic detection of fistulous tracts and foreign objects in muscles of horses. The results from water-bath studies on equine muscle in which foreign material had been inserted and then scanned ultrasonographically were compared with the results from scanning of the muscles of horses hospitalized for diagnosis of suspected foreign objects embedded in muscle. The water-bath studies showed that bone, wood, and large tendons all will demonstrate acoustic shadowing, but that subtle differences in the characteristics of the relative hyperechogenicity and acoustic shadows facilitate elimination of certain considerations in the differential diagnosis. Ultrasonography was effecti...
Splenic lymphosarcoma in a horse. A 10-year-old Tennessee Walker gelding, with a history of progressive weight loss, intermittent colic and lethargy, had a slight fever, tachycardia, tachypnea, pallor, ascites and marked ventral edema. Blood analyses revealed anemia, leukocytosis, neutrophilia with a left shift, lymphopenia, monocytosis, hypoproteinemia and a slightly increased SDH level. Abdominocentesis produced red-orange fluid with many RBC and an increased fibrinogen content. Rectal palpation revealed a large mass in the left caudal abdominal quadrant. The animal died shortly after resection of the mass. The histopatholog...
Survey of 79 referral colic cases. The clinical, surgical and/or necropsy diagnosis of 79 horses admitted to a referral clinic for evaluation of colic are reported. Twenty-one horses were presented with conditions amenable to medical treatment and all were subsequently discharged. Exploratory laparotomies were performed on 44 horses during the present study, in some cases as a diagnostic procedure preceding euthanasia. In general, in surgical cases the mortality rate was highest for problems involving the small intestine, followed by those affecting the large colon and then the small colon. Postoperative sequelae included perit...
Mycoplasma felis as a cause of pleuritis in horses. Mycoplasma felis was the only organism recovered from the thoracic cavity of a horse with pleuritis. Large numbers of mildly degenerative neutrophils were in the pleural fluid. The horse developed a serologic response to M felis and recovered during hospitalization. Experimentally, a pony was inoculated in the thoracic cavity with a pure culture of the M felis isolate suspended in the pony's serum. A control pony was inoculated with serum only. Within 48 hours, the principal pony developed fever, increased respiratory rate, pleural effusion, and signs of pain. A highly cellular exudate with no...
Mortality rates and associated factors in equine colic operations – a retrospective study of 341 operations. A retrospective survey of 300 surgical treatments for colic involving 341 interventions was carried out to determine mortality rates and associated factors. These horses had been referred to the Ontario Veterinary College over the period September 1974 to February 1980. Data from the case records was collected and stored on a computer and statistical analysis was carried out using X(2) tests.Fifty percent (150/300) of the horses survived to be discharged from the hospital. Fifty-two horses were euthanized during the operation and another ten horses should have been; if these cases are excluded...
Clostridium perfringens cellulitis and immune-mediated hemolytic anemia in a horse. A 10-year-old Quarter Horse mare was referred for evaluation and treatment of a large pectoral skin slough and hemoglobinuria. The skin slough was secondary to Clostridium perfringens cellulitis and associated gas gangrene. Cold hemagglutinin disease was diagnosed and was suspected to be secondary to C perfringens septicemia. The autoimmune hemolytic anemia, severe intravascular hemolysis, and hemoglobinuria were treated with dexamethasone and hydrocortisone. The infection was treated with 20 X 10(6) units of sodium penicillin, IV, 4 times daily, and the wound was debrided. When the mare relap...
Study of agglutinins to Brucella abortus, B canis and Actinobacillus equuli in horses. Horses at a veterinary teaching hospital and a slaughterhouse were surveyed for antibodies to Brucella abortus, B canis and Actinobacillus equuli. Four of the 141 hospitalised horses and none of the 73 slaughtered horses had titres of 1:100 or greater to B abortus. Six horses of both populations reacted to the card test. One was culture positive. A card test using B canis antigen was positive in 38 per cent of the sera from hospitalised horses and all of the slaughtered horses. Twenty (27.4 per cent) of the latter group had high tires in a tube agglutination test. High titres could not be redu...
The anion gap as a prognostic indicator in horses with abdominal pain. The anion gap was calculated for each of 90 horses with signs of abdominal pain, using laboratory data obtained shortly after admission. The anion gap was defined as the difference between the sodium concentration (mEq/L) and the sum of the chloride and bicarbonate concentrations. To evaluate the use of the anion gap as a prognostic indicator, the survival rates were calculated for horses whose anion gap concentrations were within various ranges. It was found that the probability of survival decreased as the anion gap progressively increased about 20 mEq/L. The survival rates for increasing ra...
The acute abdominal patient: postoperative management and complications. The postoperative management of the surgical colic patient varies according to the complications experienced. Many of these complications can be related to the time at which surgery is performed
relative to commencement of the problem, the condition of the patient at the time of surgery, the particular condition, and, last but not
least, the surgeon's performance. Some of the points have been discussed elsewhere in the symposium. The maintenance of asepsis, attention to minimizing trauma to the bowel, and appropriate attention
to visceral and parietal closures are all important principles. ...
Myelomonocytic myeloproliferative diseases in a horse. Myelomonocytic myeloproliferative disease in a horse was diagnosed on the basis of hematologic, enzymatic, and histopathologic findings. It was characterized clinically by depression, weight loss splenomegaly, lymphadenopathy, coagulopathy, and bacteremia. Hematologic findings included severe refractory anemia, thrombocytopenia, monocytosis, and pleomorphic leukocytes, with a left shift of the myeloid series. The serum lysozyme concentration was 14.5 microgram/ml (normal, less than 5 microgram/ml). The bone marrow contained many immature cells of the myeloid series and had a myeloid-to-erythro...
Acquired inguinal hernia in the horse: a review of 27 cases. Twenty-seven cases of acquired inguinal hernia in the horse were reviewed. The history, clinical signs, treatment, and complications were summarized. Mortality was 25.9%. Only 13 or the 27 cases were diagnosed prior to admission. With early diagnosis and treatment, mortality should approach zero. In 24 of these cases, the hernia was strangulated. In each case, the signs were colic, a firm slightly enlarged testicle in the scrotum, and small intestine displacement through the inguinal ring, as determined via rectal palpation. In was concluded that palpation of the scrotum and inguinal rings sho...
Forelimb tic in a horse. An 18-month-old male Quarter Horse was referred for evaluation of a tic that had started after injury to the right forelimb 4 weeks earlier. The right forelimb appeared paretic and had constant regular twitches of variable intensity that were usually sufficiently forceful to move the trunk, neck, and head. The horse frequently threw the limb forward. The twitch persisted during sleep but disappeared during general anesthesia and following sedation with xylazine. It was unaffected by acetylpromazine, diphenylhydantoin, diazepam, carbamazepine, trimethadione, procainamide, quinidine, propranolol...
