Randomized Controlled TrialEffects of dobutamine, dopamine, phenylephrine and noradrenaline on systemic haemodynamics and intestinal perfusion in isoflurane anaesthetised horses.
In the horse, effects of cardiovascular-active drugs on local perfusion of the gastrointestinal tract are poorly understood. ⋯ At the investigated doses dobutamine improved systemic and peripheral haemodynamics, while dopamine decreased MAP and peripheral perfusion. Noradrenaline increased MAP and SVR while peripheral blood flow was maintained, phenylephrine increased MAP, but reduced both local and systemic perfusion.

Prevalence of headshaking within the equine population in the UK.
Headshaking in horses has been reported to be most commonly due to idiopathic neuropathic facial pain (trigeminal-mediated headshaking). The prevalence of headshaking in horses in the UK is unknown. ⋯ Within this sample, owner-reported prevalence of signs of headshaking within the last year, in horses in the UK was 4.6%. Over two-thirds of owners of headshaking horses did not seek veterinary intervention for headshaking. Trigeminal-mediated headshaking was rarely reported by owners as a diagnosis.

Randomized Controlled TrialThe effect of dobutamine and bolus crystalloid fluids on the cardiovascular function of isoflurane-anaesthetised horses.
Cardiac output does not always increase with dobutamine administration in anaesthetised horses and information on peripheral perfusion is lacking. ⋯ The increase in FBF seen with co-administration of fluids and dobutamine may provide a beneficial effect on muscle compared with the use of dobutamine alone.

Randomized Controlled TrialA comparison of the effects of a 4% modified fluid gelatin and a 6% hydroxyethyl starch on haemodilution, colloid osmotic pressure, haemostasis and renal parameters in healthy ponies.
Adverse effects on renal health and haemostasis have been documented in human patients administered hydroxyethyl starches (HESs). Gelatins may represent useful substitutes should similar adverse effects be identified in horses. ⋯ Modified fluid gelatin could be considered as an alternative to HES for volume expansion and oncotic support. Neither MFG nor HES were associated with clinically significant adverse effects on haemostasis or renal parameters.

Clinical TrialFeasibility and safety of lumbosacral epiduroscopy in the standing horse.
The large size of the adult horse prevents the use of advanced imaging modalities in most areas of the axial skeleton, including the lumbosacral vertebral column. Traditional imaging techniques are frequently unable to pinpoint the underlying pathology in horses with caudal back pain. In man, lumbosacral epiduroscopy is used to diagnose and treat subjects with chronic back and leg pain. This technique may close the diagnostic gap in horses with similar clinical signs. ⋯ Lumbosacral epiduroscopy can be performed safely in sedated standing horses. The procedure may become a valuable diagnostic tool in horses with caudal back or hindlimb pain of unknown origin.
