Bronchoalveolar Lavage

Today the use of fiberoptic bronchoscopy is a common and standard diagnostic procedure, which allows direct observation of the upper and lower conducting airways. During passage of the endoscope through the nasopharynx, trachea, and large bronchi, the quantity of mucous secretions can be assessed readily in addition to the degree of mucosal edema and bronchospasm.… Read More »

Tracheal Aspirates: Technique

Several methods for obtaining TAs have been developed, each having advantages and disadvantages. The most important consideration when choosing a technique is whether microbiologic culture of the tracheobronchial secretions is indicated. In general, aspirates obtained endoscopically are unsuitable for this use because they invariably become contaminated by upper airway flora. However, a guarded catheter passed… Read More »

Postanesthetic Upper Respiratory Tract Obstruction

Upper respiratory tract () obstruction can occur in horses recovering from general anesthesia after various surgical procedures. Postanesthetic upper respiratory tract obstruction most often results from nasal edema and/or congestion and is usually mild. Other causes include arytenoid chondritis, dorsal displacement of the soft palate, and bilateral arytenoid cartilage paralysis. Bilateral arytenoid cartilage paralysis is… Read More »

Axial Deviation of the Aryepiglottic Folds

Axial deviation of the aryepiglottic folds () has been recognized as a cause of dynamic upper respiratory obstruction in horses since the first use of high-speed treadmill exercise testing to evaluate poor performance. The membranous portions of the aryepiglottic folds, which extend from the abaxial margin of the epiglottis to the corniculate processes at the… Read More »

Interpretation of Peritoneal Fluid Changes in Peripartum Mares

Abdominal discomfort in the peripartum mare poses a diagnostic dilemma for the equine clinician because of the difficulty in differentiating between normal uterine contractions and other sources of abdominal pain. When a periparturient mare displays abdominal discomfort she may be experiencing a reproductive problem including uterine torsion or rupture, vaginal tear involving the peritoneal cavity,… Read More »

Determination of Fetal Gender

Fetal gender determination has been incorporated into the management programs of many breeding farms. Depending on the sire or the dam, the fetal gender may affect the value of the fetus and therefore influence the value of the pregnant mare. This knowledge could change various management decisions such as appraisals, foaling location, sales’ reserves, insurance… Read More »
