Abstract

Objective

To assess the accuracy of a point-of-care thoracic ultrasound examination for the evaluation of the pulmonary parenchyma in rabbits without lower respiratory signs using thoracic radiography or computed tomography (CT) as the reference standard. An additional objective was to establish a baseline frequency and number of B-lines in rabbits without pulmonary disease.

Design

Prospective, multicenter, clinical study from December 2021 to July 2023.

Setting

University teaching hospital and an emergency and specialty referral center.

Animals

Sixty-three pet rabbits (Oryctolagus cuniculus) without lower respiratory signs and with lungs verified to be healthy with radiography or CT.

Interventions

Rabbits were screened for signs of respiratory disease. A modified point-of-care thoracic ultrasound examination was performed on each conscious rabbit, followed by a thoracic radiography or CT study. The frequency and number of B-lines were statistically compared based on signalment, body condition score, and health status.

Measurements and Main Results

The overall frequency of B-lines was 33.3% (21/63) in rabbits without pulmonary disease. Most B-lines were categorized as single discrete artifacts. A single region was positive for B-lines in 17 of 21 rabbits, with 14 of them having a single B-line, two having two B-lines, and one having three B-lines. Two and three regions were positive in three and one rabbit, respectively. Cranial thoracic ultrasound revealed mediastinal tissue rather than pulmonary parenchyma in 61 of 63 rabbits.

Conclusions

This study evaluated a modified point-of-care thoracic ultrasound, including B-line frequency and distribution, and described what can be expected as a normal thoracic ultrasound in rabbits without pulmonary disease. Findings indicate that isolated B-line artifacts can be detected within the lungs of rabbits without pulmonary disease. Additional studies are needed to describe the pulmonary ultrasonographic features in rabbits with respiratory conditions and to determine the clinical use of this diagnostic technique in those cases.

无肺部疾病宠物兔（Oryctolagus cuuniculus）即时胸部超声检查b线的频率和数量

目的：评价以胸片或CT为参考标准的即时胸部超声检查对无下呼吸体征家兔肺实质的评价准确性。另一个目标是在没有肺部疾病的家兔中建立b系的基线频率和数量。设计：前瞻性、多中心、临床研究，2021年12月至2023年7月。环境：大学教学医院，急诊和专科转诊中心。动物：63只宠物兔（Oryctolagus cuniculus），无下呼吸道体征，肺部经x线摄影或CT证实健康。干预措施：筛选兔子是否有呼吸道疾病的迹象。对每只有意识的兔子进行改良的即时胸部超声检查，随后进行胸部x线摄影或CT研究。基于信号、身体状况评分和健康状况，统计比较b线的频率和数量。测量和主要结果：在无肺部疾病的家兔中，b系的总频率为33.3%（21/63）。大多数b线被归类为单个离散的工件。在21只兔中，有17只兔的单个区域b -线阳性，其中14只兔有一个b -线，2只兔有两个b -线，1只兔有三个b -线。2个和3个区域分别在3只和1只兔子中呈阳性。63只家兔中有61只在颅胸超声检查中发现纵隔组织而非肺实质。结论：本研究评估了一种改进的医疗点胸部超声，包括b线频率和分布，并描述了在没有肺部疾病的家兔中可以预期的正常胸部超声。研究结果表明，在没有肺部疾病的兔子的肺部可以检测到分离的b线伪影。需要进一步的研究来描述呼吸系统疾病家兔的肺部超声特征，并确定这种诊断技术在这些病例中的临床应用。

期刊介绍： The Journal of Veterinary Emergency and Critical Care’s primary aim is to advance the international clinical standard of care for emergency/critical care patients of all species. The journal’s content is relevant to specialist and non-specialist veterinarians practicing emergency/critical care medicine. The journal achieves it aims by publishing descriptions of unique presentation or management; retrospective and prospective evaluations of prognosis, novel diagnosis, or therapy; translational basic science studies with clinical relevance; in depth reviews of pertinent topics; topical news and letters; and regular themed issues. The journal is the official publication of the Veterinary Emergency and Critical Care Society, the American College of Veterinary Emergency and Critical Care, the European Veterinary Emergency and Critical Care Society, and the European College of Veterinary Emergency and Critical Care. It is a bimonthly publication with international impact and adheres to currently accepted ethical standards.
