Dental treatment was carried out in an 8.5-year-old castrated male domestic shorthair cat found to have tooth resorption. Right mandibular, and right and left maxillary nerve blocks were administered using a 1 ml syringe attached to a 25 G x 5/8 inch needle and an intraoral technique. The following day the cat displayed blepharospasm of the right eye. The ocular signs progressed and 5 days later an ophthalmologist confirmed a blind, glaucomatous right eye. It was suspected that the eye had suffered a penetrating injury during dental surgery. Enucleation of the right eye was performed and gross and histopathological examination revealed a penetrating wound consistent with a needle tract injury.
Complications arising from veterinary dental regional anaesthesia appear to be rare; however, it may be that they are under-reported. This case report highlights the risks involved and reviews the safest and most efficacious regional anaesthesia technique for the feline maxilla.
对一只8.5岁已绝育的雄性家养短毛猫进行牙科治疗，发现其存在牙齿吸收情况。使用连接25G×5/8英寸针头的1毫升注射器及口内技术对右侧下颌、右侧和左侧上颌进行神经阻滞。次日，该猫右眼出现眼睑痉挛。眼部症状持续发展，5天后眼科医生确诊右眼失明且患有青光眼。怀疑眼睛在牙科手术期间受到穿透性损伤。遂对右眼进行眼球摘除术，大体及组织病理学检查发现一处与针道损伤相符的穿透性伤口。
兽医牙科区域麻醉引起的并发症似乎很少见；然而，可能存在报告不足的情况。本病例报告强调了其中涉及的风险，并回顾了猫上颌最安全、最有效的区域麻醉技术。
