Electroacupuncture analgesia was used for surgery in horses and donkeys. A KWD-808 electrical stimulator was used to incrementally induce a dense, dispersed wave output at frequencies from 20 to 55 Hz, which was maintained at a frequency of 55 Hz, and to change the amplitude of the wave to the best grading number for the suggested operation in each animal. Induction of analgesia lasted for 20-30 minutes, and the effect of analgesia was maintained for 20-45 minutes depending on the type of surgery performed. The exhibited clinical signs, physical examination data, and the responses of all animals were used for evaluating the periods of analgesia. Although the majority of the cases (95%) had no response to strong surgical pain, they experienced significant increases in heart rates and respiratory rates during induction. The lack of pain, relaxed surgical procedures, reduced intraoperative bleeding, and improved healing without complications were all definite benefits of using electroacupuncture analgesia in surgery. Thus, this study has provided surgical evidence supporting the effectiveness of electroacupuncture analgesia, as well as confirming its reliability, in the field of equine anesthesia and surgery.

Summary A six year old buffalo was admitted with a chronic indurated swelling at the left ramus of the mandible since 3 months. The radiographic picture showed a large osteolytic area and soft tissue swelling at the cheek teeth of the mandible. His topathological examination disclosed neoplastic epithelial cells arranged in islands and cords. The cells were arranged in palisade form resembling the ameloblasts. The clinical findings, the radiographic features and the criteria of the neoplastic cells confirmed an ameloblastoma in a buffalo.
