RESUMEN
A juvenile domestic green-winged macaw was admitted to the veterinary clinic within an hour of ingestion of lead drapery weights. Radiopaque objects were evident in the crop and ventriculus. The bird was anesthetized, and the crop was lavaged to remove lead fragments. Because lead fragments remained in the ventriculus after lavage, chelation treatment was instituted. Serial radiography was done on days 2, 5, 9, and 14 to determine passage of the lead. By day 14, lead fragments were not visible radiographically. The macaw did not have ill effects from the lead ingestion or from medical treatments. Because this bird had been observed ingesting the lead weights, treatment was for foreign body ingestion initially and for lead ingestion secondarily.

Successful diagnostic local anesthesia is dependent upon a thorough knowledge of appendicular anatomy, application of correct technique, and accurate interpretation. Use of cadaver specimens to review anatomy and practice needle placement is strongly recommended. A marker solution, such as new methylene blue, can be injected into cadaver limbs, which can be subsequently dissected to verify accuracy. Detailed interpretation of local anesthetic blocks in the lame horse reaches beyond the scope of this article. Interpretive difficulties, however, can be responsible for the failure of a block to provide useful information to the examiner, even though the block may have been performed in a technically correct manner.
