Do you know your equine practice clients? A healthy group of loyal clients is of the utmost importance for a healthy practice.Knowing the clients’ expectations and making every effort to exceed them when clients meet with the veterinarian or visit the clinic will result in continued client satisfaction. Clients will show loyalty to a veterinarian when they perceive that the care provided to them suits them and their animal and exceeds their expectations.
Ambulatory equine practice management. The horse owner not only expects outstanding care for their horse; they also recognize and appreciate a well-run equine practice. They expect their veterinarian to show up on time for appointments; they expect to receive decipherable invoices and statements on a regular basis and they appreciate an assistant who enhances the services that their veterinarian provides. A well-managed ambulatory equine practice supports the ideals of both high standards of care and mobility. In fact, a poorly managed practice will ultimately impact the care that an equine veterinarian attempts to provide the hors...

Lameness and performance evaluation in ambulatory practice. Lameness and performance evaluation can be one of the most rewarding aspects of equine veterinary practice. There is a misconception that it depends on new sophisticated and expensive diagnostic modalities, when the reality is that knowing where and when to use these modalities form the real art of equine lameness practice. The most expensive ultrasound machine in the world is not very diagnostic if applied to the wrong limb. The art of lameness practice is vested in knowledge of horsemanship, an understanding of anatomy and function, and inquiring senses to sort out what the horse and his han...
An ex vivo model for suture-less amniotic membrane transplantation with a chemically defined bioadhesive. Chemically defined bioadhesives (CDB) are "two-component reactive adhesives" made from antibiotic food additives. They contain no animal-derived ingredients and are characterized by a high level of self-degradability, low toxicity, and strong bonding properties. Amniotic membrane (AM) transplantation is used to repair severe ocular surface disease in humans and horses. AM requires meticulous suturing to the injured cornea. The purpose of this study is to determine whether CDB can facilitate the suture-less placement and adherence of equine AM to porcine cadaver cornea. Methods: Prospective stu...
Hydrallantois in the mare–a report of five cases. Hydrallantois in the mare is a very rare condition, and clinical reports help to gather information to elucidate its pathogenesis, treatment options and prognosis. Five different cases of hydrallantois in the mare are reported in this article, all with the involvement of placentitis. The five mares were presented because of acute distention of the abdomen, dyspnoea, stiff gait and a lack of appetite. After a gradual release of the excessive amount of allantoic fluid, an abortion was induced in all five mares. The foals were either born dead or euthanized. The mares recovered quickly. One mare ...

Such data are required to better evaluate the optimal time to acquire the cTnI sample following acute myocardial injury. Objective: To determine the T(1/2) of equine cTnI. Methods: Four healthy ponies received i.v. injections of recombinant equine cTnI. Plasma cTnI concentrations were measured with a point-of-care cTnI analyser at multiple time points after injection. Standard pharmacokinetic analysis was performed to establish the T(1/2) of cTnI. Resu...
Reproduction in ambulatory practice. The value of providing equine reproductive services in ambulatory setting is well established. Ambulatory practice has been, and will most likely continue to be, the primary provider of equine reproductive veterinary services. The limitations for performing various reproductive procedures in an ambulatory setting are those imposed by the amount of equipment and supplies that must be brought to the patient, as well as those imposed when procedures require additional assistance. This is analogous to human medical care: the ambulance cannot substitute for a hospital but it can certainly provide s...

Clinical experiences indicate that centesis of the lateral compartment of the femorotibial joint is often unsuccessful. Objective: To determine the accuracy of 2 published and 2 unpublished techniques of centesis of the lateral compartment of the femorotibial joint. Objective: It was hypothesised that a drug can be administered into the lateral compartment of the femorotibial joint via a diverticulum of this joint that surrounds the medial aspect of the long digital extensor tendon and that this technique is more accurate than described techniques of centesis of this compartment. Methods: Twen...
Equine ambulatory practice: challenges and opportunities. Current economic conditions make the practice of equine medicine challenging, to say the least. The downward trend in the US economy has had a huge impact on horse owners and equine veterinarians alike. Horses are expensive to keep; as such, economics are the driving factor in the problem of the unwanted horse. Under these conditions, efficient equine ambulatory practices are well-suited to weather the economic storm. As contributors to this issue of Veterinary Clinics of North America note, one can practice high-quality medicine and surgery without the overhead and expense of a large clinic. ...
Quantifying the sources of variability in equine faecal egg counts: implications for improving the utility of the method. The faecal egg count (FEC) is the most widely used means of quantifying the nematode burden of horses, and is frequently used in clinical practice to inform treatment and prevention. The statistical process underlying the FEC is complex, comprising a Poisson counting error process for each sample, compounded with an underlying continuous distribution of means between samples. Being able to quantify the sources of variability contributing to this distribution of means is a necessary step towards providing estimates of statistical power for future FEC and FECRT studies, and may help to improve t...
