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.

Pantaleon LG.Fluid therapy is an important component of resuscitation and treatment of critically ill equine patients. However, the decision of which fluid type to use in certain critical situations is somewhat controversial. This article focuses on the potential benefits of performing small-volume resuscitation in critically ill horses by combining hypertonic saline with a colloid (e.g., hetastarch).
Morris DD, Moore JN.Serum immunoglobulin (Ig) titres to core lipopolysaccharide (LPS) were determined in 102 horses admitted to a university referral hospital during a 12-month period for evaluation of colic. Serum samples were collected again 10-14 days later from 84 of the horses. Titres to core LPS were quantitated by an indirect enzyme-linked immunosorbent assay (ELISA), utilising the J-5 mutant of Escherichia coli 0111:B4 as the solid-phase antigen. All horses had natural antibodies to core LPS at the time of admission and the titre was not affected significantly by age, sex or type of gastrointestinal disor...
Sheahan BJ, Wilkins PA, Lascola KM, Martin V, Po E.Prior studies have shown the prognostic utility of measuring L-lactate in critically ill neonatal foals, both as single (at admission) and serial measurements. Greater prognostic sensitivity and specificity may be achieved by use of the area under the L-lactate versus time curve (LACArea ) over the first 24 hours of hospitalization, which captures both severity and duration of hyperlactatemia. Prior to application of this concept in sick equine neonates, a reference interval for LACArea should be determined. Methods: The concentration of lactate [LAC] was measured in blood obtained via direct ...
Riemann HP, Kaneko JJ, Haghighi S, Behymer DE, Franti CE, Ruppanner R.Hospitalized animals and stray dogs were serologically tested for antibodies against Toxoplasma gondii.

Javsicas LH, Sanchez LC.Administration of omeprazole paste per os to healthy neonatal foals has been shown to effectively increase intragastric pH, but has not been evaluated in sick neonatal foals. Objective: To determine the effect of orally administered omeprazole paste on intragastric pH in clinically ill neonatal foals requiring nasogastric intubation. Methods: Intragastric pH was measured continuously for 24 h using an indwelling electrode and continuous data recording system in hospitalised neonatal foals age < or =2 days. Intragastric pH was measured for 12 h prior to (pretreatment period) and 12 h followi...
Hartnack AK, Van Metre DC, Morley PS.To evaluate the potential association between Salmonella enterica shedding in hospitalized horses and the risk of diarrhea among stablemates, and to characterize gastrointestinal-related illness and death following discharge among horses that shed S. enterica while hospitalized. Methods: Retrospective cohort study [corrected]. Methods: 221 horses (59 that shed S. enterica during hospitalization and 162 that tested negative for S. enterica shedding ≥ 3 times during hospitalization). Methods: Information from medical records (signalment, results of microbial culture of fecal samples, clinical ...
Breuhaus BA, DeGraves FJ.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...
Corradini I, Armengou L, Viu J, Rodríguez-Pozo ML, Cesarini C, Jose-Cunilleras E.To determine if plasma iron concentration is different between horses with and without systemic inflammation (SI) and to assess the accuracy for the detection of SI by assaying plasma iron and fibrinogen concentrations, individually or combined. To assess the prognostic value of plasma iron concentration and to describe the progression of plasma iron and fibrinogen concentrations during hospital follow-up, and its relation to SI and survival. Methods: Prospective observational study evaluating plasma iron and fibrinogen. Methods: University veterinary teaching hospital. Methods: Equine patient...
