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.
Sewgobind S, Johnson N, Mansfield KL.Japanese encephalitis (JE) is an infection that occurs predominantly in Asia and the Pacific Islands. It is transmitted by mosquito bites, with the main vector being Culex tritaeniorhynchus, and is maintained in enzootic cycles involving pigs, wild birds and mosquitoes. JE is caused by infection with Japanese encephalitis virus (JEV), a zoonotic pathogen that also causes disease in mammals such as pigs and horses. In humans, most symptoms are mild or flu-like but can progress to encephalitis. Pigs are considered amplification hosts, and sows may have gestational complications. Horses may exhib...

Methods: Medical records of patients undergoing surgical treatment for colic were reviewed. Horses recovering...
Reeves MJ, Curtis CR, Salman MD, Hilbert BJ.Multiple logistic regression was used to investigate prognosis in 308 horses referred to the University of Minnesota veterinary teaching hospital with colic. Bivariate results identified the following significant individual parameters: absent or hypomotile abdominal sounds, medical or surgical classification, peritoneal fluid total protein, anion gap, serum glucose, capillary refill time, blood pH, heart rate, packed cell volume, base excess, serum chloride, plasma bicarbonate, serum urinary nitrogen and age. Two multivariable prognostic models were developed using logistic regression. Model I...
To assess injury patterns attributable to horse kicks, to raise the issue of preventive measures, and to evaluate the role of modern accident and emergency department computer software. Methods: Data analysis using a new kind of full electronic medical record. Results: Seventeen kicked equestrians were unmounted at the time of injury. Eight of seventeen patients sustained contusions of the extremities, the back, and the trunk. In nine patients an isolated facial injury was diagnosed. Five of nine patients needed referrals to the department of plastic surgery because of the complexity of the fa...
Taylor AH, Mair TS, Smith LJ, Perkins JD.The influence of synovial fluid culture on short- and long-term prognosis of cases with septic synovitis requires study. Objective: Horses with a positive bacterial culture from septic synovial fluid are less likely to survive or return to successful athletic function than those with a negative bacterial culture from septic synovial fluid. Methods: Records of mature horses presented to 2 equine referral hospitals for investigation of suspected septic synovitis were examined. Horses (n=206) were included in the study if synovial fluid was submitted for full laboratory examination, including bac...
Senior JM, Proudman CJ, Leuwer M, Carter SD.Endotoxaemia is frequently presumed on the basis of clinical signs in horses with colic. Objective: Measurements of plasma endotoxin (LPS) are rarely made in clinical cases and there is little information on the correlations between this variable, clinical variables and outcomes. Objective: To measure LPS levels in plasma of horses presented to the Philip Leverhulme Equine Hospital on admission and daily for up to 4 days and to relate LPS levels to selected clinical parameters, such as heart rate and packed cell volume, and outcomes. Methods: Blood samples were collected and stored at -20°C p...
Cohen ND, Lester GD, Sanchez LC, Merritt AM, Roussel AJ.To determine factors associated with development of postoperative ileus (POI) in horses undergoing surgery for colic. Methods: Prospective case-control study. Methods: 251 horses undergoing colic surgery, of which 47 developed POI. Methods: Signalment, history, clinicopathologic data, pre- and postoperative treatments, lesions, complications, costs, and outcome were recorded for all horses during hospitalization. Results: Variables associated with increased odds of POI included small intestinal lesion, high PCV, and increased duration of anesthesia. There was modest evidence that pelvic flexur...
Berryhill EH, Magdesian KG, Aleman M, Pusterla N.Equine coronavirus (ECoV) is a recently described enteric virus with worldwide outbreaks; however, there are little data available on clinical presentation, diagnosis, and outcome. The study objective was to document case management of ECoV in adult horses presented to a referral hospital and compare to a cohort of horses that tested negative for ECoV. A retrospective case series was performed based on positive real-time quantitative PCR results for ECoV on faeces from horses treated at the UC Davis Veterinary Medical Teaching Hospital from 1 March 2012 to 31 March 2018. Horses negative for EC...
Pascoe PJ, McDonell WN, Trim CM, Van Gorder J.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...
Soza-Ossandón P, Rivera D, Tardone R, Riquelme-Neira R, García P, Hamilton-West C, Adell AD, González-Rocha G, Moreno-Switt AI. is a highly infectious microorganism responsible for many outbreaks reported in equine hospitals. Outbreaks are characterized by high morbidity and mortality rates, nosocomial transmission to other patients, zoonotic transmission to hospital personnel, and even closure of facilities. In this study, 545 samples (environmental and hospitalized patients) were collected monthly during a 1-year period from human and animal contact surfaces in an equine hospital that received local and international horses. A total of 22 isolates were obtained from human contact surfaces (e.g., offices and pharmac...
