Effect of a constant rate infusion of lidocaine on the quality of recovery from sevoflurane or isoflurane general anaesthesia in horses. Lidocaine constant rate infusions (CRIs) are common as an intraoperative adjunct to general anaesthesia, but their influence on quality of recovery has not been thoroughly determined. Objective: To determine the effects of an intraoperative i.v. CRI of lidocaine on the quality of recovery from isoflurane or sevoflurane anaesthesia in horses undergoing various surgical procedures, using a modified recovery score system. Objective: The administration of intraoperative lidocaine CRI decreases the quality of recovery in horses. Methods: Lidocaine (2 mg/kg bwt bolus followed by 50 microg/kg bwt/min...
Changes in location of centre of pressure and hoof-unrollment pattern in relation to an 8-week shoeing interval in the horse. In order to optimise shoeing and shoeing conditions, it is essential to know how the horse adapts to a common shoeing interval. Objective: To measure changes in location of the centre of pressure (CoP) and hoof-unrollment pattern during a shoeing interval and to assess whether these changes in CoP result directly from changes in hoof conformation or are also influenced by compensatory mechanisms. Methods: Eighteen horses were trotted over a pressure-force measurement system shortly after shoeing and 8 weeks later. The position of the CoP was measured and also predicted using calculations based...
Use of serum amyloid A and other acute phase reactants to monitor the inflammatory response after castration in horses: a field study. Early recognition of excessive inflammation and infectious complications after surgery, leading to early institution of therapy, reduces post operative discomfort and facilitates recovery. Because serum amyloid A (SAA) is a highly sensitive marker of inflammation, measurements of SAA and other acute phase reactants in the equine surgical patient may be valuable in assisting clinical assessment of post operative inflammation. Objective: To investigate changes in inflammatory markers after castration and to correlate levels of acute phase reactants with clinical severity of inflammation after ca...
Black walnut extract-induced laminitis in horses is associated with heterogeneous dysfunction of the laminar microvasculature. Equine laminitis purportedly involves haemodynamic dysfunction at the level of the laminar vasculature. However, to date, no studies have been performed characterising the function of laminar arteries and veins during the prodromal stages of equine laminitis. Objective: That the prodromal stages of laminitis are associated with contractile dysfunction of the equine laminar vasculature. Objective: To assess contractile function of laminar arteries and veins to phenylephrine (PE) and 5-hydroxytryptamine (5-HT). Methods: Horses were administered black walnut heartwood extract (BWHE) or water (con...
Cross-sectional anatomy and comparative ultrasonography of the equine medial femorotibial joint and its related structures. Injuries of the equine stifle are frequent causes of hindlimb lameness. Ultrasonography is useful for the diagnosis of many soft tissue lesions but, until recently, its application to the equine stifle has been limited to a description of normal and abnormal structures. A comparative study using gross anatomical sections to identify all structures visible on ultrasonographic images of the equine stifle has not previously been reported. Objective: To provide a comprehensive comparative cross-sectional atlas of the normal equine medial femorotibial (MFT) joint and its related structures using ul...
Two clinical manifestations of desmopathy of the accessory ligament of the deep digital flexor tendon in the hindlimb of 23 horses. Desmopathy of the accessory ligament of the deep digital flexor tendon (ALDDFT) in the hindlimb is an unusual cause of lameness in horses, and reports of the condition are sparse. Objective: To describe the clinical and ultrasonographic findings, therapy and outcome of 23 horses treated for desmopathy of the ALDDFT in the hindlimb. Methods: Records of 23 horses with ultrasonographic evidence of desmopathy of the ALDDFT in one or both hindlimbs from 3 referral centres were reviewed retrospectively. Age, breed, sex, duration and nature of clinical signs, results of clinical and lameness examinat...
Radiographic scoring lacks predictive value in inflammatory airway disease. Diagnosis of inflammatory airway disease (IAD) currently rests upon the results of bronchoalveolar lavage (BAL) cytology, lung function testing and histamine bronchoprovocation (HBP), none of which provides direct information about structural change in the lung. Objective: That thoracic radiography might better portray structural change in the lungs and therefore offer a good clinical assessment of IAD. Methods: A radiographic scoring system was developed to assess the extent of bronchial and interstitial pattern on thoracic radiographs in the dorsocaudal, dorsocranial and caudoventral regions...
Effect of repeated oral administration of hypertonic electrolyte solution on equine gastric mucosa. Electrolyte supplementation is common in horses during endurance competitions, but the effect on the gastric mucosa is unknown. Objective: Repeated oral administration of hypertonic electrolyte solution is associated with exacerbation of gastric ulcers in mature horses. Methods: The study design was a randomised, blinded, crossover trial. Fourteen horses were divided randomly into equal groups and administered either 60 ml water (placebo) or 56.7 g commercial electrolyte supplement mixed with 60 ml water by dose syringe orally once an hour for 8 h. The minimum concentration of individual const...
Supernumerary cheek teeth (n = 24): clinical features, diagnosis, treatment and outcome in 15 horses. There are few reports of case series of horses with supernumerary cheek teeth (SCT) that document clinical findings, treatment and long-term outcome. Objective: To review the clinical and ancillary diagnostic findings and responses to different treatments in horses with SCT. Methods: The case records of 15 horses were reviewed and long-term outcomes obtained by telephone interview. Results: Fifteen horses with a total of 24 SCT were identified. Two SCT were incidental findings and were not treated. Clinical signs were improved or resolved in 11 of 13 of the teeth treated conservatively and all...
Assessing allocation concealment and blinding in randomised controlled trials: why bother? As users of RCT results, we must understand the potential for humans to interject bias. By describing assessments of allocation concealment and blinding, abstracts included in Evidence-Based Nursing will help readers to discern those trials that have made superior efforts to minimise bias. Judging the quality of allocation concealment and blinding reflects current empirical research and reflects the commitment of the editors of this journal to apply the principles of evidence-based practice to reporting of study findings.
Acute lung injury/acute respiratory distress syndrome in 15 foals. Few reports exist in the veterinary medical literature describing clinical and pathological findings resembling conditions described as (ALI) and acute respiratory distress syndrome (ARDS) in man. Objective: To document history, clinical, laboratory and diagnostic findings, treatment and outcome of foals age 1-12 months diagnosed with ALI/ARDS at a referral hospital. Methods: Medical records, including radiographic, cytological, microbiological, serological and post mortem findings, were reviewed in a retrospective manner to identify foals with acute onset of respiratory distress, a partial pr...
Functional consequences of cartilage degeneration in the equine metacarpophalangeal joint: quantitative assessment of cartilage stiffness. No quantitative data currently exist on the relationship of the occurrence of cartilage degeneration and changes in site-specific biomechanical properties in the metacarpophalangeal (MCP) joint in the horse. Objective: To gain insight into the biomechanical consequences of cartilage deterioration at 2 differently loaded sites on the proximal articular surface of the proximal phalanx (P1). Objective: Static and dynamic stiffness of articular cartilage decreases significantly in degenerated cartilage. Methods: Cartilage degeneration index (CDI) values were measured at the lateral dorsal margin (...
Is there a characteristic distal tarsal subchondral bone plate thickness pattern in horses with no history of hindlimb lameness? Osteoarthritis (OA) is a common cause of distal tarsal pain, but disease development is poorly understood. Awareness of normal tarsal structure and function is important in order to understand the pathogenesis of OA. Thickening of the subchondral bone (SCB) plate has been related to the development of OA, but SCB plate patterns in the equine tarsus have not been documented. Objective: There is a repeatable pattern of SCB thickness across the distal tarsal joints, and specifically that thickness would be greatest dorsally and laterally. Methods: Twenty cadaver tarsi were collected from mature h...
Incomplete sagittal fracture of the talus in 11 racehorses: outcome. Little information exists regarding talus fractures in the horse and there have been no previously published case series of racehorses diagnosed with incomplete sagittal fracture of the talus. Objective: To describe the diagnosis, treatment and post injury performance of horses with incomplete sagittal fracture of the talus. Methods: Medical records of 11 racehorses (8 Standardbreds and 3 Thoroughbreds) admitted between January 1992 and January 1999 were reviewed. Subject details, anamnesis, results of lameness examination, radiographs and nuclear scintigraphic findings were evaluated. Racing ...
Prevalence of pharyngeal and laryngeal abnormalities in Thoroughbreds racing in Australia, and their association with performance. Little information is available regarding the prevalence of abnormalities of the upper airway and their association with performance in the general population of Thoroughbred racehorses. Objective: To describe the prevalence of selected abnormalities of the upper airway and their association with performance in Thoroughbred racehorses in Australia. Objective: That abnormalities of the upper airway of Thoroughbred racehorses are associated with poor race performance. Methods: Rhinolaryngoscopy was performed after racing and presence and characteristics of abnormalities of the larynx and pharynx...
Training-related factors associated with dorsometacarpal disease in young Thoroughbred racehorses in the UK. Dorsometacarpal disease (DMD) is common in young Thoroughbred (TB) racehorses, often interfering with their training programme. No reports exist on incidence rate or associated risk factors in the UK. Objective: To estimate the incidence rate of DMD in TB horses in training for flat racing in the UK and identify associated risk factors, particularly in relation to training regimens. Methods: Data were drawn from a large prospective study in which TB horses in 13 training yards were monitored for a period of up to 2 years, recording daily training information and details of musculoskeletal inju...
Transarterial coil embolisation in 31 horses (1999-2002) with guttural pouch mycosis: a 2-year follow-up. There have been no previously published large case series describing short- and long-term outcome of transarterial coil embolisation (TCE) in horses with guttural pouch mycosis (GPM). Objective: To describe the clinical and surgical features of horses with GPM presented at the Veterinary School of Lyon during a 28 month period; and to evaluate immediate to long-term results of TCE as a treatment. Methods: Medical records of all horses with GPM treated with TCE between February 1999 and July 2002 were analysed. To be included in the study, no other surgical or medical treatment for the mycosis ...
Costs and complications of equine castration: a UK practice-based study comparing ‘standing nonsutured’ and ‘recumbent sutured’ techniques. Clinicians are often asked to guide owners and trainers over the relative advantages and disadvantages of equine castration performed in either the standing horse with an open unsutured scrotal wound with healing by second intention, or a recumbent horse under general anaesthesia in aseptic conditions, with sutured scrotal skin allowing primary wound closure. Objective: To identify types and frequency of complications following the 2 differing approaches, and to compare the financial cost associated with each procedure, based on practice charges. Methods: Veterinary expenses of 217 horses cast...
Can an external device prevent dorsal displacement of the soft palate during strenuous exercise? Dorsal displacement of the soft palate (DDSP) is a common condition in racehorses for which various surgical treatments are often performed. In light of recent findings that suggested the position of the larynx may influence the occurrence of DDSP, we investigated whether a noninvasive mean of affecting the position of the larynx could be effective in the management of DDSP. Objective: An external device (laryngohyoid support; LHS) positioning the larynx in a more rostral and dorsal location and preventing caudal displacement of the basihyoid bone would be effective in preventing DDSP during s...
Effect of composition and different fractions of hay dust suspension on inflammation in lungs of heaves-affected horses: MMP-9 and MMP-2 as indicators of tissue destruction. Airway matrix metalloproteinases (MMPs) increase following inhalation of organic dust. The relative contribution of dust components to this elevation is unknown. Objective: To identify components of organic dust responsible for elevated MMP levels in equine airways. Methods: Bronchoalveolar lavage (BALF) from 7 heaves-susceptible horses, collected 6 h following inhalation challenges with saline, 2 different hay dust suspensions (HDS-1 and -2) and soluble and particulate fractions of HDS-1, were analysed for MMP-2 and -9 using SDS-page gelatin zymography. Results: HDS-1 challenge increased BALF...
Surgical advancement of the larynx (laryngeal tie-forward) as a treatment for dorsal displacement of the soft palate in horses: a prospective study 2001-2004. Correct placement of sutures ('laryngeal tie-forward') in experimentally created dorsal displacement of the soft palate (DDSP) has been observed to replace the function of the thyrohyoideus muscles and prevent DDSP. Objective: The 'laryngeal tie-forward' procedure would prevent or delay the occurrence of DDSP during exercise in horses with naturally occurring DDSP and therefore improve performance. Methods: A clinical population (n = 116), mainly of racehorses was presented for treatment of naturally occurring exercise-induced DDSP. All horses underwent the 'laryngeal tie-forward' procedure. T...
Post operative neutrophilic inflammation in equine small intestine after manipulation and ischaemia. Post operative ileus (POI) remains an important cause of post operative morbidity and mortality in the horse. However, clinical progression of naturally occurring cases of POI in both horse and man does not entirely support the 'neurogenic' hypothesis as the sole mechanism of POI; and the hypothesis that inflammation plays a major role at 12-24 h after surgery requires validation. Objective: An inflammatory infiltrate in the muscularis externa and myenteric plexus of equine jejunum is present 18 h following a period of ischaemia. Methods: Samples of normal jejunum, jejunum from the proximal re...
Factors affecting long-term survival of horses recovering from surgery of the small intestine. Epiploic foramen entrapment (EFE) has been associated with a particularly poor post operative prognosis for equine colic cases, but the reasons for this are unknown. Objective: To identify variables associated with post operative survival following surgery for small intestinal disease; develop a model describing long-term post operative survival; and identify reasons for the poor prognosis associated with EFE. Methods: Data from 382 horses undergoing surgery were used to identify variables associated with survival. A multivariable Cox proportional hazards model for post operative survival was ...
