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.
Smith LJ, Marr CM, Payne RJ, Stoneham SJ, Reid SW.Septic arthritis is a serious problem in the neonate, with a poor prognosis being reported for recovery. The impact of neonatal septic arthritis on the likelihood that Thoroughbred (TB) foals will start on a racecourse is not known. Objective: The development of septic arthritis in a TB foal significantly reduces the likelihood that it will race when compared to foals from the same dam. Methods: Medical records of 69 foals treated for septic arthritis were reviewed. The dam's foaling records were reviewed and lifetime racing records were then retrieved for both the affected foals and at least ...

Magdesian KG.Measurements of physiologic parameters, such as blood pressure or lactate concentration, are useful to detect occult derangements, such as tissue hypoxia and dysoxia. These tools are also useful in determining the effects of therapy. Monitoring techniques are now widely available for the intensive management of critically ill horses and foals. A number of these have evolved into noninvasive or minimally invasive devices and procedures and provide information that can be used for earlier and more dynamic therapeutic intervention. The goal of increased monitoring is to improve the level of care ...

Huskamp B, Scheidemann W.Ninety-six horses with chronic recurrent caecal impaction associated with hypertrophy of muscle layers in the caecal base or in the whole caecum were examined from 1990 to 1996. Enlargement of the caecocolic orifice was completed surgically in 58 horses. Of those horses having surgery, 50 were discharged from the hospital while 8 were subjected to euthanasia at the hospital due to complications. Twenty-seven of the 50 horses discharged were normal at follow-up while 23 died or were subjected to euthanasia due to acute or recurrent colic, recurrent impaction in the ascending or descending colon...

Methods: Retrospective case series. Methods: 14 horses with ISIGL. Methods: Medical records of horses with ISIGL examined between January 1994 and December 2006 were reviewed. Signalment, initial physical examination findings, results of abdominal fluid analysis, and clinical laboratory values were recorded, along with surgical findings, including segment of incarcerated intestine and surgical procedures...
Vatistas NJ, Wright IM, Dyson SJ.Forty-eight horses with osteochondritic lesions of the femoropatellar joint were treated, 23 of them by an arthrotomy and 25 by arthroscopy. Follow-up information was obtained from either the owner or the referring veterinarian by telephone inquiry. There were no statistical differences between the groups of horses undergoing the two procedures with regard to age, sex, breed, the involvement of one or both limbs, the size of the lesion, and the duration of either the surgery or anaesthesia. However, the horses treated by an arthrotomy spent 14.5 days in hospital after the operation whereas tho...
Welschen SE, de Bruijn CM, Sloet van Oldruitenborgh-Oosterbaan MM.The short- and long-term results of admission to the 'Neonatal Intensive Care Unit' (ICU) at the Department of Equine Sciences of the Utrecht University were evaluated. The patients were categorized, based on specific criteria, into different groups: 'Sepsis', 'Pneumonia', 'Enteritis', 'Asphyxia', 'Premature', 'Isoerythrolysis', and 'Equine herpes virus (EHV)'. The survival rate and mean duration of hospitalization were determined for each group. The venous blood variables at admission were compared for 'surviving' and 'non-surviving' foals within groups, between groups, and for the overall gr...
Stanbouly D, Besmer AV, Chuang SK.The purpose of our study is to assess the severity of craniomaxillofacial injuries from horseback-riding accidents. Methods: This is a 20-year retrospective cross-sectional study of the National Electronic Injury Surveillance System. Injuries from the activity of horseback-riding were included if they occurred in the craniomaxillofacial complex. Study predictors were derived from both patient and injury characteristics. The study outcome was the presence or absence (probability) of hospital admission from the emergency department. A multiple logistic regression model was created to model the o...
