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.
Equine motor neuron disease: findings in 28 horses and proposal of a pathophysiological mechanism for the disease. Over a three and one-half year period, 28 adult horses were diagnosed with equine motor neuron disease (EMND). The most commonly identified environmental risk factors for a horse having EMND were absence of grazing for more than a year and provision of poor quality hay. Quarter Horses were 5.4 times more at risk than other breeds but this was thought to be an epiphenomenon related to the frequency of Quarter Horses at boarding stables. Weight loss, excessive recumbency and/or trembling were the first signs noted. Other clinical diagnostic signs included: constant shifting of the weight in the ...
Surgical treatment for epiglottic entrapment in horses: 51 cases (1981-1992). Medical records of 51 horses with epiglottic entrapment were reviewed, and the outcome after surgical treatment was evaluated by use of results from a survey of owners and from race records. Horses with epiglottic entrapment and no additional problem (uncomplicated) of the nares, nasal passages, pharynx, or larynx (upper airway) that were treated by transoral axial division (group 1) or resection via laryngotomy (group 2), and horses with epiglottic entrapment complicated by an additional upper airway abnormality (group 3) were compared. The cost of treatment, duration of hospitalization, time...
Review of 40 cases of lung abscesses in foals and adult horses. A retrospective study of 40 horses with primary lung abscesses without pleuropneumonia showed that lung abscesses occurred predominantly in young horses, usually in foals aged < or = 6 months. Hyperfibrinogenaemia was present in all but 2 horses, and other common clinical and haematological findings were hyperthermia, tachycardia, polypnoea, and neutrophilic leucocytosis. The most common bacterial species isolated from transtracheal aspirates were Streptococcus zooepidemicus (20/34) and Rhodococcus equi (13/34). Most horses (23/27) discharged from the hospital were long term survivors. Of t...
Horseback riding injuries among children and young adults. Horseback riding injuries are responsible for an estimated 2300 hospital admissions annually among persons younger than 25 years of age in the United States, but injury rates, patterns of injury, and risk factors for this population have not been well studied. Methods: Study participants were selected from a list provided by a national mail-order company that sells riding equipment. A total of 557 persons younger than 25 years of age who rode horses at least six times a year completed survey questionnaires. Results: Among the study participants, 34 (6.1%) had been hospitalized at least once be...
Systemic candidiasis in four foals. Four foals were admitted to the neonatal intensive care unit in the first 2 days of life with problems related to birth hypoxia (neonatal maladjustment syndrome, renal failure, necrotizing enterocolitis) and sepsis. Foals were hospitalized for an extended period (35 to 70 days) and received treatment with several broad spectrum antimicrobial agents. Invasive monitoring and treatment procedures included intravenous catheterization, urinary catheterization, and parenteral nutritional and ventilatory support. In each foal, infections of undetermined cause developed, and systemic candidiasis was d...
A retrospective study of vein thrombosis in horses treated with intravenous fluids in a veterinary teaching hospital. The medical records of 68 horses treated with IV fluids for 24 hours or more were reviewed to determine the risk of vein thrombosis and to determine which factors were associated with the occurrence of vein thrombosis in these horses. Three factors were positively associated with vein thrombosis including use of locally produced fluids and presence of fever and diarrhea. Two factors, having general anesthesia or having surgery, were negatively associated with vein thrombosis. One continuous variable, duration of treatment, was positively associated with vein thrombosis. Factors not associated ...
Comparison of measured and calculated values for colloid osmotic pressure in hospitalized animals. A relation exists between colloid osmotic pressure (pi) and serum total protein concentration; equations describing this relation have been used to determine a calculated value for pi. However, the relation between total protein concentration and pi is altered by the method used to measure protein and by changes in the ratio of concentrations of albumin (A) to globulin (G). We developed nomograms for estimating pi from A and G concentrations, using samples obtained from clinically normal animals and compared the accuracy of these nomograms with that of previously described equations relating p...
Partial closure of laryngotomies in horses. In horses, ventral laryngotomies are typically allowed to heal by second intention. Partial closure of the laryngotomy incision, however, was associated wtih less exudate, less aftercare, shorter hospitalization, and better cosmetic results, compared with the traditional technique. The partial closure technique did not result in complications in the 3 horses in which it was attempted.
Ventilatory support of the neonatal foal. Many sick neonatal foals have respiratory failure secondary to perinatal hypoxia, sepsis, or pneumonia. These foals require ventilatory support to prevent respiratory embarrassment and other complications associated with chronic hypoxia and hypercapnia. This article discusses practical aspects of ventilatory therapy, such as choosing a candidate for mechanical ventilation, choosing the proper ventilatory mode, placing a foal on a ventilator, maintaining a foal on mechanical ventilation, and weaning from mechanical ventilation. This article details some of the techniques that have been develope...
Equestrian injuries: a five-year review. A retrospective chart review was conducted to define the demographic and injury patterns of patients presenting to the emergency department (ED). The setting is a rural/small urban tertiary care center with approximately 40,000 visits per year. All patients presenting to the ED from January 1986 through December 1990 with equestrian-related injuries were enrolled in the study. Measurements included age, sex, mechanism of injury, injury or injuries diagnosed, admission to the hospital, morbidity, and mortality. A total of 142 patients met the inclusion criteria. The majority of injuries occurre...
Tetanus in the horse: a review of 20 cases (1970 to 1990). The case records of 20 horses with tetanus referred to the Ontario Veterinary College-Veterinary Teaching Hospital between 1970 and 1990 were reviewed. The fatality rate was 75%. There was a strong association with previous vaccination and survival (P = .03). Most of the animals had been injured an average of 9 days (range 2 to 21 days) prior to development of clinical signs. Hyperesthesia and prolapse of the third eyelid were the most common clinical signs. Treatment regimens varied during hospitalization; however, all horses received parenteral penicillin, tranquilizers, tetanus toxoid, and ...
Is horse riding a dangerous recreation for young girls? A study at emergency departments of Lahti City Hospital and Päijat-Häme Central Hospital, Lahti. Horse-related injuries form a notable part of sports and leisure time accidents. 54% of the injured were female riders under the age of 20 years. The most serious injuries were upper extremity ones. Over one third of the riders had suffered previously from horse-related injuries.
The effects of cisapride on the restoration of gut motility after surgery of the small intestine in horses; a clinical trial. Seventy horses surgically treated for colic caused by disorders of the small intestine were included in a randomized blind trial to determine the effects of cisapride (0.1 mg/kg bw intramuscularly at 8-h intervals) on the post-operative restoration of gut motility. Cisapride appeared to reduce the incidence of post-operative ileus. It accelerated the restoration of bowel motility, reducing the period of post-operative intensive care. It is concluded that cisapride is an effective and useful drug in the post-operative treatment of horses after surgery of the small intestine.
Plasma endotoxin concentrations in clinically normal and potentially septic equine neonates. Plasma endotoxin concentrations were measured at 1 to 2 and 5 to 6 days of age in clinically normal foals and in potentially septic neonatal foals admitted to North Carolina State University's Veterinary Teaching Hospital for a variety of conditions. In 1 to 2 and 5 to 6 day old normal foals, median plasma endotoxin concentrations were 2.17 (range, 1.61-2.54; n = 6) and 2.89 (range, 2.61-3.50; n = 7) endotoxin units/mL (EU/mL), respectively. Median plasma endotoxin concentration in potentially septic foals with negative blood cultures or gram positive isolates (n = 8) was 2.73 (range, 0.59-4.0...
Injuries due to falls from horses. This study describes the epidemiology of injuries due to falls from horses in New Zealand. There were 54 fatalities from 1977 to 1986 (0.17 per 100,000 persons per year). There were 773 hospitalisations in 1987 (23.7 per 100,000 persons per year). Head injuries were predominant among both fatal and nonfatal injuries. The incidence of nonfatal head injury in the 10 to 19 age group was significantly higher than the incidence in all older groups (P = 0.003). Young people, particularly females, were the segment of the population most affected by the problem of falls from horses. Reference to data ...
Analysis of hemostasis in horses with colic. Eight tests of hemostasis were measured in 233 horses with colic. Blood samples were obtained at admission and for 4 consecutive days of hospitalization. Data were analyzed retrospectively by outcome, by broad-category diagnosis group, by small intestinal disorder, and by smaller categories for comparing specific diseases. Nonsurviving horses and horses with the most severe forms of intestinal ischemia had changes interpreted as hypercoagulative, the intensity of which was increased on the first and second mornings (sample times 2 and 3) after admission, when most significant differences for r...
Retrospective analysis of the results of 151 exploratory laparotomies in horses with gastrointestinal disease. Of 149 horses that underwent 151 exploratory laparotomies for gastrointestinal disorders from September 1987 to May 1991, 107 (72%) were discharged from the hospital: 100 (66%) survived for > 7 months, 94 of which returned to their intended use. Survival rate (64/80) for horses with caecum/large colon obstruction was significantly (P = 0.003) higher than for horses with small intestinal obstruction (33/64). Prolonged surgery was associated with significantly (P < 0.001) lower survival rates than short surgical time. In the large intestine, survival rate (15/29) for strangulated obstructions wa...
Hematuria and leptospiruria in a foal. A Thoroughbred foal that was born after 305 days of gestation was referred 6 hours after birth. On initial examination, the foal was alert, but weak and unable to stand. Heart rate was 150 beats/min, respiratory rate was 48 breaths/min, and rectal temperature was 33 C. Leukocytosis was detected (26,000 WBC/microliters). Dysuria and passage of red urine was observed approximately 30 hours after admission. Urine collected by free catch had a 3+ reaction for blood on dipstick analysis. Examination of Warthin Starry-stained sections of allantochorion revealed organisms morphologically characterist...
Clinical pharmacokinetics of amikacin in hypoxic premature foals. The pharmacokinetics of amikacin, administered iv at 7 mg/kg, every 8 h, were evaluated over the first 48 h of hospitalisation in 7 critically ill hypoxic premature foals and compared with those in 8 full-term nonhypoxic critically ill neonatal foals. The pharmacokinetic data were used to calculate dosage schedules that would maintain the plasma amikacin concentrations in individual foals within a target range of > or = 15 micrograms/ml but < 30 micrograms/ml for peak values and < or = 3 micrograms/ml for trough values. The results indicated a statistically significant increase in the amikacin...
Relationship of serum total calcium to serum albumin in dogs, cats, horses and cattle. A retrospective study was performed in order to assess the relationship between serum calcium and serum albumin concentrations in domestic animals. Results of 9041 canine, 1564 feline, 2917 equine, and 613 bovine serum samples from hospitalized patients were examined by regression analysis. Subpopulations of cases with concurrent elevations in creatinine or that were less than six months of age were evaluated separately. Statistically significant linear relationships between calcium and albumin concentrations were established for each species (p <0.05). The coefficients of determination (r(...
Serological titers of equine monocytic ehrlichiosis associated with gastro-intestinal disorders and serological follow-up on two endemic farms. The purpose of this work was to study the association of positive serological titers to Ehrlichia risticii, the causative agent of equine monocytic ehrlichiosis (EME) with gastro-intestinal disorders in hospitalized horses referred to The Ohio State University College of Veterinary Medicine Teaching Hospital (OSU VMTH). In addition, serological titers for E. risticii were monitored in two horse populations with endemic EME for one season to monitor temporal changes in titers. A statistically significant difference was found between the proportion of the total hospitalized horse population pres...
Squamous cell carcinoma associated with a chronic wound in a horse. A 13-year-old Belgian stallion developed a squamous cell carcinoma at the site of a neck laceration that had been treated topically with various irritating chemicals for 18 months. Orthovoltage treatments at 3 times over 5 years controlled the tumor. Eight years after the initial hospitalization, the area was healed and the stallion appeared healthy.
Jejunal intussusception in adult horses: 11 cases (1981-1991). Medical records of 11 adult horses with jejunal intussusception examined at 5 veterinary teaching hospitals between 1981 and 1991 were reviewed. Nine of 11 horses had signs of acute abdominal discomfort for < 24 hours, whereas 2 horses had a history of chronic signs. Five of 11 horses had an intraluminal or intramural mass associated with the jejunal intussusception. Two horses died or were euthanatized prior to surgery. Partial jejunal resection and jejunojejunal anastomosis were performed in 9 horses. One horse died during surgery and 2 were euthanatized prior to hospital discharge because o...
A retrospective study of 192 horses affected with septic arthritis/tenosynovitis. The medical records of 192 horses with septic arthritis/tenosynovitis 1979-1989 were reviewed. Forty-three horses developed infection after an intra-articular injection, 46 following a penetrating wound, 25 following surgery, 66 were foals less than 6 months old, and 12 were adult horses without a known aetiology. Haematogenous infection of a joint occurs in adult horses and should be considered as a differential diagnosis in horses with an acute onset of severe lameness. The aetiology of the infection had a significant effect on the type of bacteria identified by culture. Staphylococcus was c...
Prognostic indicators for horses with duodenitis-proximal jejunitis. 75 horses (1985-1989). The medical records of 75 horses with duodenitis-proximal jejunitis (DPJ) were reviewed. Ages, physical parameters, laboratory values, and treatment data were compared between horses surviving DPJ and horses not surviving DPJ (Table 1). Fifty of 75 horses (66.6%) survived. Sixty-six horses (88.0%) were managed with medical treatment alone and nine horses (12.0%) were managed with medical treatment plus surgical intervention. Using a logistic regression model, the association of each of the 19 physical and laboratory parameters with death was evaluated retrospectively in the 75 horses. Three pa...
Open drainage, intra-articular and systemic antibiotics in the treatment of septic arthritis/tenosynovitis in horses. Open drainage was used to treat 26 horses with persistent or severe septic arthritis/tenosynovitis. Infected synovial structures were drained through a small (3 cm) arthrotomy incision that was left open and protected by a sterile bandage. Joint lavage was performed in all 26 horses. In addition to systemic antibiotics, 23 of these horses were also treated with intra-articular antibiotics; amikacin (17 horses), gentamycin (2 horses), cefazolin (2 horses), and 2 horses were injected at different times with gentamycin and amikacin. The infection was eliminated from the involved synovial structur...
Ventricular arrhythmias in horses: 21 cases (1984-1989). Ventricular premature depolarizations (VPD) were identified in 21 horses in which unexplained tachycardia or an arrhythmia was detected on auscultation. Horses were categorized into 3 groups on the basis of ECG findings. Seven horses had uniform isolated VPD (group 1); 7 horses had repetitive uniform VPD at a rate or = 100 VPD/min (group 3). Concurrent systemic disease was identified in 12 horses, 7 of which had gastrointestinal tract disorders. Serum cardiac isoenzyme activities were high in 6 (2 from each group) of 13 horses in which they were measured. Serum electrolyte concentrations were...
Removal of nasogastric tube fragments from three horses. Three horses were admitted for retrieval of polyurethane nasogastric tube fragments. The fragments were removed from the esophagus or stomach of 2 horses by manipulation of a snare introduced through the biopsy port of an endoscope. The fragments were surgically removed from the stomach of the third horse.
Surgical treatment of colic in American miniature horses: 15 cases (1980-1987). A study of 15 American miniature horses (AMH) that underwent surgical treatment for colic was performed. Information obtained from the medical records included signalment, clinical signs, type and location of gastrointestinal lesion, and postoperative complications. All 15 AMH had intraluminal obstructions, attributable to feed impactions (11 horses), enteroliths (2), and sand (2). The most common location of obstruction was the small colon, which was involved in 9 of the 15 cases. All 15 AMH survived and were discharged from the hospital. Six of the 15 AMH underwent subsequent surgical treatm...
Steroid hepatopathy in a horse with glucocorticoid-induced hyperadrenocorticism. Steroid hepatopathy was diagnosed in a horse with glucorticoid-induced hyperadrenocorticism on the basis of anamnesis, serum biochemical data, and histologic findings of hepatic biopsy. Initially, clinical signs of polyuria, polydypsia, and muscular degeneration were seen. The horse developed laminitis during hospitalization.
