Research in this area focuses on evaluating the efficacy, safety, and outcomes of different treatment modalities. This page collects peer-reviewed research studies and scholarly articles that explore the methods, advancements, and clinical outcomes associated with equine treatment practices.
Frost GE, du Preez HR.A 3 year old thoroughbred colt in full training pulled up
acutely lame during a training gallop on a dirt track.
According to the trainer no reason for the injury was
evident. The horse refused to bear weight on the leg
and when forced to walk back to the stables it would
only touch the affected toe to the ground. The fetlock
soon became swollen and was very painful. The trainer
treated the animal for a sprain with ice packs and
bandages. No improvement occurred in 72 hours and
veterinary advice was sought.
Examination revealed the horse to be in obvious
pain. He was unable to bear ...
Hilbert BJ, Farrell RK, Grant BD.Squamous cell carcinoma around the eyes of 3 horses was treated with liquid nitrogen, using cryotherapy probes as the method of application. In 2 cases, there was complete regression of the tumor; in the 3rd case, remission and relief of discomfort were temporary.
McMullan WC, Joyce JR, Hanselka DV, Heitmann JM.Amphotericin B was used systemically or locally, or both, in the treatment of localized subcutaneous phycomycosis in horses. In 8 of 10 cases, the results were satisfactory. Intravenous treatment was well tolerated at an average starting daily dosage of 0.38 mg/kg, increasing up to as high as 1.47 mg/kg. It was concluded that the ideal treatment regimen would include early surgical removal of the lesion followed by daily intravenous and topical administration of amphotericin B, with periodic extirpation of small necrotic tracts as necessary.
Lyons ET, Drudge JH, Tolliver SC.In 1 experiment, a prepatent period of 8 or 9 days was recorded for Strongyloides westeri in 4 pony foals raised worm-free but infected with parasitic 3rd stage larvae in the postpartum milk of a mare via gastric intubation. This is about 2 to 6 days less than the usual age that eggs of S westeri appear in the feces of naturally infected suckling foals, in central Kentucky.
In other studies, mares were treated with cambendazole or thiabendazole at 0 to 2 days after parturition and continued for 7 to 16 days. Appearance of S westeri eggs in feces of foals nursing treated mares was prevented ...
Sanders RK, Martyn B, Joseph R, Peacock ML.In a two-year study of 322 conservatively treated, consecutive cases of tetanus in a rural hospital (all over twelve months old), intrathecal administration of 200 units of antitetanus serum (A.T.S.) (horse) reduced the overall mortality of 4-5% (5/110) compared with 14-5% (16/111) in the control series. 200 units intrathecal A.T.S. (horse) gave better results than 1500 units A.T.S. (horse). The results with lumbar and cisternal administration did not differ. It is suggested that tetanus is a polysystemic condition requiring polysystemic therapy. A regimen in which intrathecal A.T.S. is given ...
Scheel J, Duswald KH, Ring J, Seifert J, Scholz S, Brendel W.Eight mongrel dogs received a standard daily i.v. infusion of 20 mg/kg b.w. deaggregated horse-anti-dog-lymphocyte-globulin (ALG) and additional prednisolone (1 mg/kg b.w. daily i.v.) over a maximum period of 82 days following pretreatment with deaggregated normal horse IgG. No sensitization against horse protein was observed during therapy of afterwards as proved by lack of humoral antibodies against horse antigens, maintained lymphopenia, good compatibility, longterm prolongation of xenogeneic skin graft survival (85.6+/-20.6 days, n=8' untreated controls 12.5+/-1.3 days, n=4) and longterm s...
Orzan F, Angelini P, Oglietti J, Leachman RD, Cooley DA.Two cases of horseshoe lung are described; one was suspected and the other was diagnosed preoperatively. Both underwent successful surgical treatment. The embryology of this anomaly is briefly reviewed with reference to the closely related scimitar syndrome (anomalous venous return of right lung to inferior atriocaval junction). Diagnostic studies are discussed with stress on the need for a thorough functional evaluation of both the heart and lungs before the surgical indication is made.
Eales FA.Saffan was injected intravenously on 41 occasions in 11 horses and ponies to investigate its possible use in clinical equine anaesthesia. The optimum dose for induction was 1-90 mg per kg. This dose was divided into two halves, the first half given in five seconds and the second half, containing suxamethonium chloride 0.1 mg per kg, in the next 10 seconds. Induction was associated with excitement for up to 30 secs after the assumption of recumbency. At this dose rate anaesthesia lasted five to eight minutes. Muscle relaxation was poor. Recovery was associated with marked tactile and audible hy...
Cooper MJ.Fluprostenol (ICI 81,008) is a 16-aryloxyprostaglandin, structurally related to PGF2alpha. It is a highly potent luteolytic agent, being effective in thoroughbred mares at a single intramuscular dose of 250 mug and having a wide margin of safety in this species. A total of 941 mares have been treated with fluprostenol in an international trial, for various forms of infertility associated with abnormal persistence of luteal function. These mares were selected for treatment on the basis of clinical examination and 760 (approximately 80 per cent) responded fluprostenol by showing oestrus within s...
McKay AG, Milne FJ.A project to determine if intraarticular corticosteroid therapy was deleterious to the racing Thoroughbred was carried out in the 1971, 1972, and 1973 racing seasons. Of 22 horses available for follow-up examination, 6 had radiographic evidence of deterioration; 1 of these was destroyed because of probable corticosteroid-induced arthropathy. The remaining 16 horses did not have any evidence of deterioration. One of the 16, a stakes winner, had been given 12 injections into the left front fetlock during the 3-year period. It was concluded that if proper and careful aftercare is adhered to, intr...
Gretener P.On the basis of an examination carried out on 41 healthy horses, a correlation was established between the average breath stream strength (Vol./Time) during both inspiration and expiration and the breath volume per minute. In the range of breath volume between 45 and 200 liters per minute, it was found that there was a close linear correlation between the breath stream strength, both inspiratory and expiratory, and the breath volume per minute. Comparative examinations, carried out on 56 horses suffering from obstructive lung diseases, have shown that such diseases resulted in a reduction of t...
Nelson AM.Of 275 mares receiving prostaglandin F2alpha-Tham salt for its luteolytic effect upon the corpus luteum, 231 (84 per cent) exhibited signs of oestrus (range 73-95 per cent). Some mares not exhibiting overt oestrus may, nevertheless, ovulate and post-treatment rectal palpation of mares apparently failing to respond is suggested in these cases. Of 210 mares for which subsequent history was available. 104 (49.5 per cent) became pregnant from breeding at the post-treatment oestrus that immediately followed the induced regression of the corpus luteum (range 42.2-55.5 per cent). Fertility is compara...

Morales CJ, Sykes BW, McKemie DS, Kass PH, Knych HK.Current treatment options for equine gastric ulcer syndrome (EGUS), such as omeprazole-a proton pump inhibitor (PPI)-have notable limitations, including the need for administration on an empty stomach. Potassium-competitive acid blockers (P-CABs), such as vonoprazan, are a newer class of acid suppressants that offer several advantages over PPIs in humans and may provide similar benefits in horses. Objective: To describe the pharmacokinetics and effect of a single oral dose of vonoprazan on intragastric pH in horses. We hypothesised that vonoprazan would follow linear kinetics across the doses ...
Gandini M, Giusto G.Most studies on colic surgery outcome focus on short-term survival and complications. Long-term outcomes, particularly post-discharge morbidity, are poorly characterised despite their relevance. No standardised system has previously integrated both short- and long-term postoperative complications with survival outcomes. Therefore, this study aimed to evaluate long-term survival and morbidity in horses after colic surgery using the equine postoperative complication score (EPOCS), and to assess the association between complications and survival. Methods: The medical records of horses undergoing ...
So YM, Kwok WH, Yap C, Wong COL, Smalley SGR, Forbes BS, Chow DWY, Ho ENM.This paper describes the detection and longitudinal monitoring of cyclosporine in plasma and urine after subconjunctival implant administration in a horse. Sensitive liquid chromatography tandem mass spectroscopy (LC-MS/MS) methods for detecting cyclosporine in horse plasma and urine have been developed and validated, with estimated limits of detection down to 1 pg/mL in both matrices. The developed methods enabled longitudinal monitoring of cyclosporine levels in blood and urine samples collected over 6 months from a horse that had received an ocular cyclosporine implant.
