Practice tip: Bronchoalveolar lavage



Bronchoalveolar lavage (BAL) is an under-utilised procedure in the investigation of equine respiratory disease. It provides information on lower airway inflammation that cannot be obtained from a tracheal aspirate. In the diagnosis of Recurrent Airway Obstruction, Summer Pasture-Associated Recurrent Airway Obstruction and Inflammatory Airway Disease it provides more reliable cytological inflammation than a tracheal aspirate. The procedure is safe, straightforward and inexpensive to perform.
