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.
Båverud V, Gustafsson A, Franklin A, Lindholm A, Gunnarsson A.Clostridium (C.) difficile, or its cytoxin, was demonstrated in faecal samples from 10 of 25 (40%) mature horses investigated with acute colitis treated primarily with antibiotics for disorders other than diarrhoea. C. difficile was not found in faecal samples from 140 horses without signs of enteric disorders, from 21 nondiarrhoeic horses treated with antibiotics, nor from 22 horses with colitis untreated with antibiotics. Except for C. difficile neither Salmonella nor any other investigated intestinal pathogen was isolated in any of the diarrhoeic horses. The findings strongly support some e...

Kriss TC, Kriss VM.Thirty million Americans ride horses; 50,000 of these riders are treated in emergency rooms annually. Equestrian activities are uniquely dangerous because the participant is unrestrained, often helmetless, and riding large, unpredictable animals capable of 40-mph speeds and kicking with up to 1 ton of force. Neurologic injuries in equestrians constitute the majority of severe injuries and fatalities. We prospectively studied all patients admitted to the University of Kentucky Medical Center with equine-related neurosurgical trauma from July 1992 to January 1996. Eighteen of 30 patients were ma...
Cable CS, Fubini SL, Erb HN, Hakes JE.The case records of 119 young horses (all less than age one year) that underwent an exploratory celiotomy during a 17 year period were examined to determine the surgical findings, short- and long-term outcome, and prevalence of small intestinal disease compared to previous reports in the mature horse. Physical and laboratory values were compared for long-term survivors vs. nonsurvivors and the frequency of post operative intra-abdominal adhesions was determined. The most common cause for exploratory celiotomy was small intestinal strangulation, followed by enteritis and uroperitoneum. Six hors...
Carr EA, Carlson GP, Wilson WD, Read DH.To characterize history, clinical signs, and pathologic findings in horses with histologically confirmed acute hemorrhagic pulmonary infarction and necrotizing pneumonia. Methods: Retrospective study. Methods: 21 horses. Results: 19 of the 21 horses were Thoroughbred racehorses in training. Eighteen horses had had strenuous exercise immediately prior to onset of illness. Fifteen horses had a serosanguineous nasal discharge during hospitalization. Seventeen horses had radiographic evidence of pulmonary consolidation and pleural effusion. Nine of 14 horses had ultrasonographic evidence of large ...
Furr M, Tinker MK, Edens L.This study was conducted to develop an equation for the prediction of outcome in neonatal foals undergoing treatment in an intensive care unit (ICU). Fifty-three physical examination, historical, and clinicopathologic variables were analyzed from the records of 99 neonatal foals (< 14 days of age) treated in the neonatal ICU of the Equine Medical Center. The outcome was recorded and the results were categorized into either surviving or nonsurviving groups. The mean values for the 2 groups were compared, and variables that differed significantly between the two groups were retained and used ...
Frazer GS, Perkins NR, Blanchard TL, Orsini J, Threlfall WR.A retrospective investigation was performed to determine the population characteristics of horses presented for dystocia at 2 equine referral hospitals and the types of fetal maldispositions among these horses. The study population consisted of a similar number of Thoroughbreds (25%), Standardbreds (24%) and draft horses (22%). Most of the current literature pertaining to equine obstetrics is based on a predominately draft horse population (63%). The latter population appeared to have more transverse presentations (P = 0.06), possibly because of the higher number of draft mares. In our study, ...
Parraga ME, Spier SJ, Thurmond M, Hirsh D.The purpose of this study was to evaluate the effects of probiotic administration on the prevalence of fecal shedding of Salmonella, the prevalence of postoperative diarrhea, the length of antimicrobial therapy, and the length of the hospitalization stay during the postoperative period in horses with colic. Two commercially available probiotics for horses were used in a double-blind prospective study of 200 horses undergoing surgery for colic. Probiotic or placebo was administered PO once a day for 7 days postoperatively, and fecal cultures for Salmonella were obtained daily for 10 days. After...
Dart AJ, Peauroi JR, Hodgson DR, Pascoe JR.In this retrospective study, postoperative ileus was studied in horses having resection of the small intestine followed by a jejunojejunal (n = 35) or a jejunocaecal (n = 35) anastomosis. Twenty-six horses received no metoclopramide, 27 received metoclopramide as an intermittent intravenous infusion and 17 horses received metoclopramide as a continuous intravenous infusion (0.04 mg/kg/hour). Horses receiving a continuous infusion of metoclopramide had a reduced total volume (P < 0.001), shorter duration (P < 0.001), and a slower rate (P < 0.001) of postoperative gastric reflux, and a ...
Guglick MA, MacAllister CG, Ewing PJ, Confer AW.A 12-year-old Quarter Horse gelding was admitted to the veterinary medical teaching hospital with a 2-day history of signs of abdominal pain. Initial findings on physical examination included signs of lethargy, dehydration, diarrhea, and gastric reflux. Results of laboratory testing indicated that the horse had panleukopenia with neutrophilic toxic changes, was dehydrated, and was hypocalcemic. During the first 48 hours of hospitalization, 1 abdominal palpation per rectum and 3 analyses of peritoneal fluid were performed; abnormalities were not detected. A preliminary diagnosis of enterocoliti...
Cohen ND, Honnas CM.To determine the incidence of the risk factors for developing diarrhea in horses after celiotomy for colic. Methods: Retrospective cohort study. Methods: 357 adult horses that had celiotomy for colic at the teaching hospital between Jan 1, 1990 and Sep 1, 1994. Methods: Medical records of horses that had celiotomy for colic were reviewed to abstract information regarding development of diarrhea, signalment, history, and treatment. Results: In horses that had celiotomy for colic, the incidence of diarrhea was 53.2% (190/357). Using multiple logistic regression, horses with a disorder of the lar...
Hartmann FA, Callan RJ, McGuirk SM, West SE.Salmonella anatum was isolated from horses treated at a private veterinary clinic or at a university veterinary medical teaching hospital. All isolates were resistant to most commonly used antibiotics. Because of the severity of disease resulting from outbreaks of infections with drug-resistant strains of S anatum, an epidemiologic investigation was conducted. Enteric bacteria, including S anatum, that were resistant to most antibiotics were isolated from the private veterinary clinic environment. Salmonella anatum was not isolated from the university teaching hospital environment. To prevent ...

Methods: Retrospective analysis of medical records. Methods: 219 horses housed in the intensive care unit of a veterinary medical teaching hospital from October 1991 through May 1992. Methods: Bacteriologic culturing of fecal samples was used to identify horses shedding S krefeld. For affected horses, the scan statistic was used to analyze temporal clustering, and Knox's method was used to analyze temporal-spatial clustering. Results: 20 ...
Wilson DA, MacFadden KE, Green EM, Crabill M, Frankeny RL, Thorne JG.Trimethoprim-potentiated sulphonamides (TPS) are among the most frequently administered antimicrobials in equine medicine. Anecdotally, TPS has been implicated as a cause of mild to moderate diarrhea in horses. The purpose of this study was to document the prevalence of diarrhea in horses receiving TPS, to characterize the severity of the diarrhea, and to identify any other factors associated with the development of diarrhea. A 2-part study was designed to identify the prevalence of diarrhea associated with TPS in our clinic population. Part I was a case-control retrospective study of 135 reco...
Murray RC, Debowes RM, Gaughan EM, Bramlage LR.Closed fractures of the proximal aspect of the ulna were repaired in 10 horses younger than or equal to 6 months of age by application of a hook plate using a tension band principle. Ulnar fractures were classified as type 1A (2 horses), type 1B (4 horses), type 2 (1 horse), type 3 (1 horse), and type 4 (2 horses); all fractures had displacement of a proximal fragment. Complications were implant deformation (4 horses), screw pullout (1 horse), osseous sequestration (1 horse), ulnar fracture through a hole used to apply a tension device (1 horse), and metacarpophalangeal deformity associated wi...
Laverty S, Lavoie JP, Pascoe JR, Ducharme N.Clinical features, treatment and outcome of 15 horses with penetrating thoracic wounds are described. The most common cause of trauma was collision with an object (10 horses). Concurrent clinical findings included subcutaneous emphysema (12 horses), pneumothorax (12 horses), haemothorax (5 horses) and pneumomediastinum (6 horses). Axillary wounds were present in 5 horses. Foreign bodies were identified and removed from 2 horses. Wounds were sutured (6 horses) or packed (7 horses). Air was evacuated from the pleural cavities of 11 horses. Eleven horses (73%) were discharged from the hospital. A...
Seltzer KL, Byars TD.To determine the percentage of Thoroughbred racehorses that would be capable of racing performance after recovery from infectious pleuropneumonia. Methods: Retrospective case series. Methods: 70 Thoroughbred horses that had recovered from pleuropneumonia. Only horses 5 years old known to be in race training at the time of illness were included in the study. Results: Forty-three of the 70 (61%) horses raced after recovery, and 24 of the 43 (56%) won at least 1 race. Horses that required placement of an indwelling thoracic drain apparently did not have a worse prognosis than did horses that did...
Topper MJ, Prasse KW.To evaluate new ELISA for measurement of thrombin-antithrombin III (TAT) concentration, and to correlate the values to other tests of hemostasis in horses with colic. Methods: Plasma TAT concentration and 8 other hemostasis analytes were measured in horses with colic at hospital admission and during the next 4 days. Retrospectively, data were analyzed by outcome, broad-category diagnosis, and clinical management, and for correlation between TAT and other assays. Methods: 100 horses with colic. Methods: Plasma samples were evaluated for TAT, fibrinogen, and fibrin degradation products concentra...
Raisis AL, Hodgson JL, Hodgson DR.Equine neonatal septicaemia was confirmed in 24 foals hospitalised at the Rural Veterinary Centre between 1989 and 1992 with suspected septicaemia. Septicaemia was confirmed by culture of bacteria from blood of live foals and tissues obtained at necropsy of foals that died or were euthanased. Pathogenic bacteria isolated were predominantly Enterobacteriaceae (including Escherichia coli and Salmonella serovars) and Actinobacillus equuli. Clinical manifestations of septicaemia included signs of depression, dehydration, abnormalities in body temperature and manifestations of localised infection i...
Moore RM, Hance SR, Hardy J, Moore BR, Embertson RM, Constable PD.Colonic luminal pressure (median, range) measured during ventral midline celiotomy in 69 horses with strangulating obstruction (SO) of the large colon (SO; > or = 270 degrees large colon volvulus; 27 cm H2O: 2 to 80 cm H2O) was greater (P = .0023) than that measured in 37 horses with nonstrangulating obstruction (NSO) of the large colon (NSO; < or = 180 degrees volvulus or a nonstrangulating displacement; 18 cm H2O; 6 to 46 cm H2O). Sixty-five percent (45 of 69) of horses with SO and all horses with NSO survived. Survival analysis was restricted to 59 horses with large-colon SO that survived t...
Vatistas NJ, Snyder JR, Wilson WD, Drake C, Hildebrand S.Sixty-seven foals age < 150 days underwent a ventral celiotomy for colic. Of the 67 foals, 51 foals (82%) recovered from anaesthesia and 42 (63%) were subsequently released from the hospital. Three (6%) of the 51 foals were subjected to a repeat celiotomy. Long term follow-up was available on 36 foals. Twenty-nine (57%) of the 51 foals recovered from anaesthesia, were alive at least 2 years following surgery. Adhesions were identified in 8 (17%) of the foals which recovered from general anaesthesia but were subsequently subjected to euthanasia due to recurrent colic. Strangulating lesions were...
Larsen J, Dolvik NI, Teige J.Case histories, results of laboratory analyses, treatment regimens and outcome are described for 13 horses that developed acute enterocolitis after various surgical treatments. Twelve of the 13 horses had been cast in lateral recumbency, and 10 of those 12 had received general anesthesia. Eleven horses had been treated with antimicrobial drugs. Most horses (11) developed diarrhea 2 days after initiation of treatment, with a variation from 1 to 5 days. The most apparent symptoms were fever, up to 40.5 degrees C, elevated heart rate, discoloration of mucous membranes, and diarrhea. Dehydration, ...
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...
Doxey DL, Milne EM, Harter A.The outcome for 35 horses with chronic dysautonomia which were kept in the hospital at the Royal (Dick) School of Veterinary Studies and subsequently returned to their owners is recorded. They constituted 42.7 per cent of the 82 chronic cases seen between 1991 and 1994; the other 47 horses were euthanased while in hospital. Of the 35 animals returned to their owners four died and 27 were available for follow up; of these 27, 12 were working competitively and six were being trained for future competitive work. It takes at least a year before it is clear whether a horse can compete successfully ...

Methods: Retrospective case series. Methods: Seven adult horses with grade-3 rectal tears. Methods: A single-incision loop colostomy was performed with horses under general anesthesia (n = 6) or while restrained in standing stocks (n = 1). The rectal tear was lavaged via an endoscope. The colostomy was resected after the rectal tear healed. Results: Rectal tears ranged from 4 to 10 cm in diameter and were > 25 cm proximal to the anus. All horses survived colostomy surger...
Leroux AJ, Schott HC, Hines MT.Ventricular tachycardia was diagnosed in a 12-year-old unconditioned Appaloosa gelding after a 3-day trail ride. Initial signs were those of abdominal discomfort, ileus, and dehydration. Medical treatment included IV administration of lactated Ringer's solution. During hospitalization, the horse developed ventricular tachycardia. Serum potassium concentrations were within reference limits; however, assessment of total body potassium stores was not performed. Resolution of the arrhythmia occurred with further fluid treatment and potassium supplementation. Cardiac arrhythmias should be considere...
Madewell BR, Tang YJ, Jang S, Madigan JE, Hirsh DC, Gumerlock PH, Silva J.Intestinal colonization with toxigenic strains of Clostridium difficile was documented in 9 of 10 horses with acute onset diarrhea in a veterinary medical teaching hospital, whereas a similar isolate was detected in only 1 of 23 other horses without diarrhea in the hospital. One horse with diarrhea was infected simultaneously with both C. difficile and Salmonella krefeld. Clostridium difficile was detected by fecal culture on selective medium, confirmed with a latex particle agglutination test, and identified as toxigenic by polymerase chain reaction amplification of toxin A and toxin B gene s...
Honnas CM, Schumacher J, McClure SR, Crabill MR, Carter GK, Schmitz DG, Hoffman AG.Medical records of 10 horses with olecranon bursitis were reviewed to examine treatments, evaluate a technique for en bloc resection of the bursa in standing horses, and determine outcome of the horses after treatment. Before admission, 6 horses had been treated by needle aspiration of fluid from the mass, followed by injection of corticosteroids. Subsequent treatment for 2 of these 6 horses included open drainage and packing of the cavity with gauze soaked in 7% iodine solution. None resolved after these treatments. After admission to the hospital, 5 horses were treated medically and 5 were t...

Methods: A prospective observational study of all children less than 15 years of age who were brought to the University of Virginia children's Emergency Department with horse-related injuries. Results: During the two-year period of the study, 32 children were evaluated. Two children were injured when a horse stepped on them. Thirty children fell from or were thrown from a horse. Of these, 20 were wearing a helmet. Head injuries were more frequent in those patients not wearing helmets. The mean Mod...
Dabareiner RM, White NA.Medical records from all horses with large colon impaction admitted between 1985 and 1991 were examined. Large colon impaction was diagnosed in 147 of 1,100 (13.4%) horses with colic. One hundred thirty horses were admitted for further evaluation of acute onset of abdominal pain after having been examined and treated by referring veterinarians, and 17 horses that were hospitalized for unrelated medical problems developed large colon impaction. Female horses (92/147; 62.6%) were more commonly affected than males. The age ranged from 1 to 29 years (median, 7.1 years). Mean duration of clinical s...
Oosterlaan-Mayer B, Back W, Sloet van Oldruitenborgh-Oosterbaan MM.All horses and ponies with laminitis treated at the Department of Equine Sciences, Faculty of Veterinary Medicine, Utrecht University, between 1995 and 1998 were analysed retrospectively (n = 152). Based on the results of this study and on the world-wide knowledge on laminitis a standardised treatment protocol was adopted in 1999. Fifty-eight patients have been treated for laminitis between 1999 and 2001 following the treatment protocol. Compared to our hospital-population (orthopaedic patients), mares and ponies are at higher risk developing laminitis, but the prognosis does not differ betwee...
van Bömmel-Wegmann S, Gehlen H, Barton AK, Büttner K, Zentek J, Paßlack N.Little is known about the animal- and diet-related factors that could interfere with the plasma zinc (Zn) concentrations of equines. Additionally, the adequacy of plasma to reflect changes in the Zn intake is unclear. In the first part of this study, the plasma Zn concentrations of hospitalized horses and ponies ( = 538) were measured and evaluated for the impact of the age, sex, horse type, and internal diseases of the animals. In the second part, the effects of increasing dietary Zn chloride hydroxide and Zn methionine supplementations were assessed on the plasma and mane hair Zn concentrati...

Bousum PC.There is no simple recipe for designing a multifaceted practice. However, keys to any design are the devotion of the people involved and proper positioning of such people in the organization. Anyone designing such a practice also must pay keen attention to details and a keep a finger constantly on the pulse of the business to ensure that it maintains a sound financial footing and a consistent vision. Little money is made from savings or pushing financials. Profits come mainly through building additional sales, maintaining a clear vision, and making shrewd investments. Like for every small busi...
Hall S, McElligott S, Sadek AR, Griffith C, Waters R, Nader-Sepahi A. Accidents during sporting activities are a common cause of head injury, particularly in children and young adults. Whilst most sporting head injuries are minor, there remains a proportion which is associated with high morbidity and mortality. The epidemiology of sports associated head injuries is variable based on geographical region so the aim of this study was to review the management and outcomes of sporting head injuries managed by a single neurosurgical unit in the South of England. A retrospective review of the Trauma Audit and Research Network database was conducted for all patients ad...

Bladon BM, Hillyer MH.Extensive resection of the ileum of the horse, using automated stapling equipment followed by a stapled jejunocaecostomy, without closure of the mesenteric defect, was evaluated prospectively as a surgical treatment for lesions involving the distal small intestine. Of 153 horses treated surgically for colic, 10 horses with strangulating lesions involving the distal ileum were treated by extensive resection and jejunocaecal anastomosis leaving a residual mesenteric defect. These were compared with 12 horses with jejunoileal lesions treated by jejunocaecal anastomosis with closure of the mesente...
Ravary B, Fecteau G, Higgins R, Paré J, Lavoie JP.Bacteriologic detection of Salmonella spp. from feces of animals admitted to Veterinary Teaching Hospital of the Faculty of Veterinary Medicine, University of Montréal, in Saint-Hyacinthe was carried out during a 1-year period to estimate the prevalence of bovine and equine salmonellosis. Prevalence at the time of hospitalization was quite low: 1.4% in cattle and 1.7% in horses. Incidence was 15.1 cases/100 animal/year in cattle and 38.7 cases/100 animal/year in horses. Serotype typhimurium was the most prevalent in both species. In cattle, cases were evenly distributed over the year. In hors...
Fjordbakk CT, Arroyo LG, Hewson J.A retrospective study of 63 horses diagnosed with limb cellulitis between 1994 and 2005 was conducted. They all had an acute onset of painful, generalised limb swelling, and a clinical diagnosis of limb cellulitis was made by the attending clinician. None of the horses had more than one limb affected. Hindlimbs were significantly more often affected than the forelimbs (P<0.05). Thoroughbreds were significantly over-represented compared with the general distribution of breeds examined at the hospital. Blunt limb trauma, limb surgery and limb injections were associated with the cellulitis in mos...
Furr M, McKenzie H.Bloodstream infections (BSI) are common in sick foals and increase foal morbidity and mortality when they occur. Recognition of risk factors for BSI could be an important means to limit their occurrence, but studies on this topic are limited. Objective: Historical as well as maternal and foal physical examination findings will predict risk of BSI in neonatal foals. Methods: Foals <14 days of age admitted to a referral equine hospital for care. Methods: Retrospective case-control study with univariate and multivariable logistic regression analysis. Results: Four hundred twenty-nine (143 cases...
Cuny C, Witte W.MRSA infections in equine clinics were reported from Northern America, Europe, Australia, and Japan. The majority of nosocomial infections in horses is obviously associated with particular MRSA clonal lineages. As already observed for epidemic MRSA in human hospitals more than 10 years ago, a dynamics of MRSA clonal lineages is also observed in European equine clinics: clonal lineages belonging to clonal complex (CC) 8 are on the retreat whereas MRSA attributed to CC398 become increasingly prevalent. The majority of CC398 isolates belong to a subpopulation which is particularly associated with...
Gandini M, Giusto G.Accurate reporting of postoperative complications is paramount to understanding procedural outcomes, comparing procedures and assuring quality improvement. Standardising definitions of complications in equine surgeries will improve the evidence of their outcomes. To this end, we proposed a classification for postoperative complications and applied it to a cohort of 190 horses undergoing emergency laparotomy. Methods: A classification system for postoperative complications in equine surgery was developed. Medical records of horses that underwent equine emergency laparotomy and recovered from an...

Green SL, Conlon PD.The pharmacokinetics of amikacin, administered iv at 7 mg/kg, every 8 h, were evaluated over the first 48 h of hospitalisation in 7 critically ill hypoxic premature foals and compared with those in 8 full-term nonhypoxic critically ill neonatal foals. The pharmacokinetic data were used to calculate dosage schedules that would maintain the plasma amikacin concentrations in individual foals within a target range of > or = 15 micrograms/ml but < 30 micrograms/ml for peak values and < or = 3 micrograms/ml for trough values. The results indicated a statistically significant increase in the amikacin...
León CA.The purpose of this study was the identification of possible sequelae of the infection of human individuals with Virus of Venezuelan Equine Encephalitis (VEE). Special emphasis was laid on exploring neurological, psychological and behavioural aspects and particularly on the search for a possible association of the disease with epileptic phenomena, brain damage and/or mental deficiency. A four-year period of observation was conducted on a sample of children from El Carmelo (Colombia) where an epidemic of VEE took place in 1967. A group of seven children who presented the encephalitic type of th...
Luethy D, Feldman R, Stefanovski D, Aitken MR.Acute colitis is a serious cause of morbidity and death in horses.

A medical reason for POR was presumed wh...
Vatistas NJ, Snyder JR, Wilson WD, Drake C, Hildebrand S.Sixty-seven foals age < 150 days underwent a ventral celiotomy for colic. Of the 67 foals, 51 foals (82%) recovered from anaesthesia and 42 (63%) were subsequently released from the hospital. Three (6%) of the 51 foals were subjected to a repeat celiotomy. Long term follow-up was available on 36 foals. Twenty-nine (57%) of the 51 foals recovered from anaesthesia, were alive at least 2 years following surgery. Adhesions were identified in 8 (17%) of the foals which recovered from general anaesthesia but were subsequently subjected to euthanasia due to recurrent colic. Strangulating lesions were...
Blikslager AT, Bowman KF, Levine JF, Bristol DG, Roberts MC.Medical records of horses that underwent surgical treatment for colic between 1990 and 1992 were reviewed. Horses with a pulse rate of > or = 60 beats/min or signs of abdominal pain, which were also accompanied by a volume of > 2 L of material that refluxed from the stomach during the postoperative period (excluding horses with anterior enteritis), comprised the postoperative ileus (POI) group. Horses that had < 2 L of material reflux during the postoperative period and survived > 3 days after surgery comprised the reference population. The association of preoperative and intraoperative clinic...
Kim LM, Morley PS, Traub-Dargatz JL, Salman MD, Gentry-Weeks C.To evaluate factors potentially associated with fecal Salmonella shedding among equine patients hospitalized for colic at a veterinary teaching hospital and to determine the effects of probiotic treatment on fecal Salmonella shedding and clinical signs. Methods: Longitudinal study and controlled trial. Methods: 246 equine colic patients. Methods: History and medical information were obtained from patient records. Fecal and environmental samples were submitted for aerobic bacterial culture for Salmonella enterica. Fifty-one patients were treated with a commercially available probiotic; 46 were ...
Vörös K, Felkai C, Szilágyi Z, Papp A.Two-dimensional echocardiographic (2DE) examination was performed on a horse with clinical signs of pericardial effusion. Thickening of the pericardium, excess amount of pericardial fluid, elevation of the cardiac apex, and right ventricular compression, characteristic of cardiac tamponade, could be seen on 2DE recordings. Fibrinous pericarditis was suspected by observation of fibrinous strands in the pericardial fluid and epicardial fibrin deposits. Echocardiographically guided pericardiocentesis was performed, and 4 L of fluid was removed from the pericardial sac. Streptococcus zooepidemicus...
Bertin FR, Reising A, Slovis NM, Constable PD, Taylor SD.The epidemiology of equine neorickettsiosis (EN) has been extensively studied but limited clinical and clinicopathological data are available concerning naturally infected horses. Objective: Factors predictive of survival will be identified in horses diagnosed with EN. Methods: Convenience sample of 44 horses with EN admitted to 2 referral institutions. Methods: A retrospective study was performed. A diagnosis of EN was based on the presence of positive blood or fecal PCR. Results: The most common clinical signs included diarrhea (66%), fever (50%), anorexia (45%), depression (39%), colic (39%...
Beroza GA.In horses, ventral laryngotomies are typically allowed to heal by second intention. Partial closure of the laryngotomy incision, however, was associated wtih less exudate, less aftercare, shorter hospitalization, and better cosmetic results, compared with the traditional technique. The partial closure technique did not result in complications in the 3 horses in which it was attempted.
Laverty S, Lavoie JP, Pascoe JR, Ducharme N.Clinical features, treatment and outcome of 15 horses with penetrating thoracic wounds are described. The most common cause of trauma was collision with an object (10 horses). Concurrent clinical findings included subcutaneous emphysema (12 horses), pneumothorax (12 horses), haemothorax (5 horses) and pneumomediastinum (6 horses). Axillary wounds were present in 5 horses. Foreign bodies were identified and removed from 2 horses. Wounds were sutured (6 horses) or packed (7 horses). Air was evacuated from the pleural cavities of 11 horses. Eleven horses (73%) were discharged from the hospital. A...
