To evaluate the effectiveness and treatment outcome of a minimal surgical debridement and antimicrobial-impregnated gauze packing technique for treatment of dental abscesses in rabbits.
Retrospective case series.
13 rabbits with 14 dental abscesses.
Medical records of pet rabbits with dental abscesses were reviewed. Rabbits that underwent a wound-packing treatment protocol with a follow-up period of > 6 months were included. Pretreatment evaluation included physical examination, skull radiography, CBC and plasma biochemical profile, and an endoscopically guided dental examination. The surgical procedure consisted of lancing the abscess, cleaning the cavity, minimal debridement, and packing with strips of synthetic gauze impregnated with a selected antimicrobial. Purulent material from abscesses was submitted for bacterial culture. The procedure was repeated weekly until abscess resolution. Rabbits also received systemic treatment with antimicrobials.
Rabbit ages ranged from 1 to 5 years. Anaerobic bacteria were cultured from 6 abscesses and aerobic bacteria from 5; no bacteria were cultured from 4 abscesses. Antimicrobials most commonly used in packing procedures were ampicillin and clindamycin; trimethoprim-sulfamethoxazole with metronidazole and azithromycin were given most often for systemic treatment. Thirteen of 14 abscesses resolved, and rabbits were followed for a mean ± SD period of 32.6 ± 24.3 months. Number of packing procedures used to obtain resolution of infection was 4.8 ± 2.2.
Minimal surgical debridement followed by antimicrobial-impregnated gauze packing of the abscess cavity is an effective and practical option for the long-term resolution of dental abscesses in rabbits when combined with systemic treatment with appropriate antimicrobials.
评估一种微创外科清创术和抗菌浸渍纱布填塞技术治疗兔牙脓肿的有效性和治疗效果。
回顾性病例系列。
13只患有14处牙脓肿的兔子。
回顾宠物兔牙脓肿的病历。纳入接受伤口填塞治疗方案且随访期>6个月的兔子。治疗前评估包括体格检查、颅骨X线摄影、全血细胞计数和血浆生化指标，以及内镜引导下的牙齿检查。手术过程包括切开脓肿、清理腔隙、微创清创，并用浸渍了选定抗菌药物的合成纱布条填塞。将脓肿的脓性物质送检进行细菌培养。每周重复该程序，直至脓肿消退。兔子还接受了抗菌药物的全身治疗。
兔子年龄在1至5岁之间。6处脓肿培养出厌氧菌，5处培养出需氧菌；4处脓肿未培养出细菌。填塞程序中最常用的抗菌药物是氨苄西林和克林霉素；甲氧苄啶-磺胺甲恶唑与甲硝唑和阿奇霉素最常用于全身治疗。14处脓肿中的13处消退，兔子的平均随访期为32.6±24.3个月。用于实现感染消退的填塞程序次数为4.8±2.2次。
与使用适当抗菌药物的全身治疗相结合时，微创外科清创术继以脓肿腔抗菌浸渍纱布填塞是长期解决兔牙脓肿的有效且实用的选择。
