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.

Kamr AM, Dembek KA, Gilsenan W, Bozorgmanesh R, Hassan HY, Rosol TJ, Toribio RE.Hypocalcemia is a common finding in critically ill equine patients. Parathyroid hormone (PTH) helps to maintain calcium homeostasis in hypocalcemic patients by promoting renal calcium reabsorption and bone resorption. Increased serum PTH concentrations have been reported in critically ill people and animals, including horses and foals. It is unknown whether increased secretion of PTH is associated with markers of bone turnover in hospitalized foals. The goals of this study were to measure markers of bone resorption (C-terminal telopeptide of type I collagen [CTX-I]) and bone formation (osteoca...

Torcivia C, McDonnell S.Horses have evolved to show little indication of discomfort or disability when in the presence of potential predators, including humans. This natural characteristic complicates the recognition of pain in equine patients. It has been our clinical impression that, whenever a person is present, horses tend to "perk up" and ongoing discomfort behavior (DB) more or less ceases. The objective of this study was to quantitatively evaluate and describe this effect. For each of 20 orthopedic surgical patients, continuous 24-h video was reviewed to record all occurrences of DB during a caretaker visit (3...
Tirosh-Levy S, Gottlieb Y, Steinman A.Stress has been suggested as a risk factor for Theileria equi peracute disease and may lead to relapse in clinical signs in chronically infected horses.

Methods: Retrospective case-control study. Methods: Horses aged ≥20 years (geriatric, n = 78) and 4-15 years (mature non-geriatric, n = 156) that had exploratory celiotomy for colic and survived recovery from general anesthesia. Methods: Medical records (2000-2010) of horses that recovered from general anesthesia after colic surgery were reviewed. Postoperative complications evaluated included postoperative reflux (POR), diarrh...
Borchers A, Wilkins PA, Marsh PM, Axon JE, Read J, Castagnetti C, Pantaleon L, Clark C, Qura'n L, Belgrave R, Schwarzwald C, Levy M, Bedenice D....Evaluation of serial blood lactate concentrations [LAC] are of prognostic value for morbidity and mortality in critically ill human patients and neonatal foals, but have not been prospectively evaluated in a large multicentre study of critically ill neonatal foals. Objective: To prospectively evaluate the prognostic value of sequential [LAC] analysis in critically ill neonatal foals with risk of mortality. Methods: Prospective, observational study. Methods: Thirteen university and private equine referral hospitals enrolled 643 foals over the 2008 foaling season and [LAC] was measured at admiss...
Daniel AJ, Leise BS, Burgess BA, Morley PS, Cloninger M, Hassel DM.To compare the perioperative response of serum amyloid A (SAA) to fibrinogen in horses requiring exploratory celiotomy for colic and to determine if SAA could be used to predict complications and outcome. Methods: Prospective observational clinical study. Methods: University teaching hospital. Methods: Eighteen horses undergoing exploratory celiotomy for colic. Inclusion criteria for the study included survival and anesthetic recovery from exploratory celiotomy, no history of surgery within the past year. Methods: Blood was obtained via jugular venipuncture before surgery (time 0) and at 24, 4...
Mutore K, Lim J, Fofana D, Torres-Reveron A, Skubic JJ.There is a paucity of evidence about traumatic injuries and their sequelae sustained due to equestrian injuries nationally. Methods: Retrospective study analyzing National Trauma Data Bank data from 2007 to 2016. Variables collected included age, sex, race, payer status, Injury Severity Score (ISS), hospital length of stay, Glasgow Coma Scale, systolic blood pressure (SBP) at presentation, discharge disposition, and mortality. Patient data were analyzed by anatomic region. Results: The most frequent type of injury was in the thorax, but head and neck injuries produced the highest mortality. In...

Van Hao N, Loan HT, Yen LM, Kestelyn E, Hong DD, Thuy DB, Nguyen NT, Duong HTH, Thuy TTD, Nhat PTH, Khanh PNQ, Dung NTP, Phu NH, Phong NT, Lieu PT....Intramuscular antitoxin is recommended in tetanus treatment, but there are few data comparing human and equine preparations. Tetanus toxin acts within the CNS, where there is limited penetration of peripherally administered antitoxin; thus, intrathecal antitoxin administration might improve clinical outcomes compared with intramuscular injection. In a 2 × 2 factorial trial, all patients aged 16 years or older with a clinical diagnosis of generalised tetanus admitted to the intensive care unit of the Hospital for Tropical Diseases, Ho Chi Minh City, Vietnam, were eligible for study entr...
Steel CM, Hunt AR, Adams PL, Robertson ID, Chicken C, Yovich JV, Stick JA.To identify factors affecting the prognosis for survival and athletic use in foals with septic arthritis. Methods: Retrospective study. Methods: 93 foals with septic arthritis. Methods: Medical records were reviewed to obtain clinical findings, laboratory test results, radiographic findings, treatment method, and outcome. Race records for Thoroughbreds and Standardbreds were evaluated to determine whether foals subsequently raced and whether they raced successfully. Results: 43 foals had 1 affected joint, 44 foals had multiple affected joints, and number of affected joints was not recorded for...
Sutton GA, Ertzman-Ginsburg R, Steinman A, Milgram J.Initial assessment of the mortality rates and prognostic indicators in horses with colic presented to a referral hospital in Israel. Objective: To determine mortality rates and to identify potential prognostic indicators in horses undergoing treatment for colic. Methods: The medical records of 208 colic cases were reviewed and mortality rates calculated including 95% confidence intervals. Mortality rates in surgical cases were calculated separately for strangulating and nonstrangulating lesions as well as for lesions of the large and small intestines. Potential prognostic indicators were ident...
