The purpose of this report is to describe the anesthetic and analgesic management and the surgical procedures of gonadectomy in six (four females and two males) healthy adult Egyptian fruit bats (). Bats were anesthetized with a combination of alfaxalone, midazolam, and morphine administered subcutaneously. Incisional line infiltration using bupivacaine was administered in all bats, and additional bilateral intratesticular injection was administered in the males. Ovariectomy was performed a dorsal approach, by bilateral midline skin incisions at the paralumbar fossa level. Orchiectomy was performed a ventral approach, by bilateral midline incisions of scrotal skin above the testes. Following surgery, all bats were administered flumazenil for midazolam reversal, and meloxicam for postoperative analgesia, subcutaneously. All bats recovered from anesthesia uneventfully. Bats were monitored for complications up to 10 days following surgery, when skin sutures were removed. No morbidities or mortalities occurred during this period in any of the bats. In conclusion, ventral approach orchiectomy and dorsal approach ovariectomy using the injectable combination alfaxalone-midazolam-morphine in conjunction with local anesthesia and meloxicam are feasible procedures in Egyptian fruit bats and can be performed with relative ease. However, further studies using these techniques in a larger group of bats should be performed to establish their safety.
本报告旨在描述六只（四只雌性和两只雄性）健康成年埃及果蝠性腺切除术的麻醉和镇痛管理以及手术过程。蝙蝠通过皮下注射阿法沙龙、咪达唑仑和吗啡的组合进行麻醉。所有蝙蝠均采用布比卡因进行切口浸润，雄性蝙蝠还进行了双侧睾丸内注射。卵巢切除术采用背侧入路，在腰旁窝水平进行双侧中线皮肤切口。睾丸切除术采用腹侧入路，在睾丸上方进行阴囊皮肤的双侧中线切口。手术后，所有蝙蝠均皮下注射氟马西尼以逆转咪达唑仑的作用，并注射美洛昔康用于术后镇痛。所有蝙蝠均顺利从麻醉中恢复。术后对蝙蝠进行长达10天的并发症监测，直至拆除皮肤缝线。在此期间，任何一只蝙蝠均未出现发病或死亡情况。总之，在埃及果蝠中，采用阿法沙龙-咪达唑仑-吗啡注射组合联合局部麻醉和美洛昔康进行腹侧入路睾丸切除术和背侧入路卵巢切除术是可行的手术，且相对容易实施。然而，应使用这些技术在更大数量的蝙蝠群体中进行进一步研究以确定其安全性。
