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.

Schneider RK, Bramlage LR, Mecklenburg LM, Moore RM, Gabel AA.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...

Alward A, Corriher CA, Barton MH, Sellon DC, Blikslager AT, Jones SL.Ingestion of wilted red maple leaves by horses can result in severe hemolytic anemia and methemoglobinemia. Little is known about what factors influence the outcome of red maple leaf toxicosis in horses. Objective: Our hypothesis was that physical examination findings, clinicopathologic variables or therapeutic modalities may predict outcome in horses with red maple leaf toxicity. Methods: Horses with red maple leaf toxicosis presented to referral hospitals in the southeast region of the United States. Methods: A multi-institutional retrospective study was designed to identify factors that pre...
Hardy J, Minton M, Robertson JT, Beard WL, Beard LA.The clinical findings and outcome of 161 horses diagnosed with 174 episodes of nephrosplenic entrapment (NSE) were reviewed retrospectively. The median age at presentation was 5 years (9 months to 24 years), and duration of colic was 2-92 h. Nasogastric reflux was present in 49 of 113 horses (43.4%) and was significant (> or = 21) in 32 (28.3%) horses. The recurrence rate was 13/161 (8.1%). Thirteen horses (13/174, 7.5%) had other lesions including small intestinal obstruction (4), 360 degrees large colon torsion (5), gastric rupture (2), thromboembolic colic (1) and small colon infarction (1)...
