背景:休息时的上呼吸道(URT)内窥镜检查通常用于评估具有URT条件的竞赛草马。地面内窥镜检查可能是草马URT评估的首选,因为它允许马匹用背带驱动,在与气道状况最突出的表演环中经历的类似情况下,过度检查和推车负载。
目的:描述具有异常呼吸噪音和/或表现不佳的比赛草马的运动URT结果。
方法:案例系列。
方法:回顾了在2013年1月至2018年1月期间接受地面内窥镜评估的竞赛草马的医疗记录,这些记录表现为异常呼吸噪音和/或表现不佳。在所有马匹中评估了静息和地上内窥镜检查的视频记录。在休息和运动时喉功能之间计算Spearman的等级相关系数。
结果:检查了50匹竞赛草马。13人之前曾接受过URT手术。静息和运动喉功能之间存在显着相关性(ρ=0.77,P<0.01)。在46匹马中检测到异常,包括类软骨塌陷(n=31),声带塌陷(n=27),腭功能障碍(n=14),会厌障碍(n=11),动态喉部塌陷(n=1),腭咽弓的头端偏离(n=3)和臂会厌褶皱的内侧偏离(n=16)。大多数马具有复杂的异常(n=31)或需要进行运动检查以进行识别(n=41)。在9匹马中观察到偶然的上食管功能不全。
结论:回顾性收集数据。
结论:地上内镜评估是识别竞赛草马URT障碍的有用技术。运动中确定的上呼吸道状况范围支持使用地上内窥镜作为诊断技术,并可能影响治疗考虑。该摘要有葡萄牙语版本-请参阅支持信息。
BACKGROUND: Upper respiratory tract (URT) endoscopy at rest is commonly used to evaluate competition draught horses with URT conditions. Overground endoscopy might be preferred for draught horse URT evaluation as it allows the horses to be driven with harness, overcheck and cart-load under similar conditions to those experienced in the show ring where airway conditions are most prominent.
OBJECTIVE: To describe the exercising URT findings of competition draught horses with abnormal respiratory noise and/or poor performance.
METHODS: Case series.
METHODS: Medical records of competition draught horses undergoing overground endoscopic evaluation between January 2013 and January 2018 with a presenting complaint of abnormal respiratory noise and/or poor performance were reviewed. Video recordings of resting and overground endoscopy were evaluated in all horses. Spearman\'s rank correlation coefficient was calculated between laryngeal function at rest and at exercise.
RESULTS: Fifty competition draught horses were examined. Thirteen had previously undergone URT surgery. There was significant correlation between resting and exercising laryngeal function (ρ = 0.77, P<0.01). Abnormalities were detected in 46 horses and included arytenoid cartilage collapse (n = 31), vocal fold collapse (n = 27), palatal dysfunction (n = 14), epiglottic disorders (n = 11), dynamic laryngeal collapse (n = 1), rostral deviation of the palatopharyngeal arch (n = 3) and medial deviation of the aryepiglottic folds (n = 16). The majority of horses had a complex of abnormalities (n = 31) or required exercising examination for identification (n = 41). Incidental upper oesophageal incompetence was observed in nine horses.
CONCLUSIONS: Retrospective collection of data.
CONCLUSIONS: Overground endoscopic evaluation was a useful technique for identifying URT disorders in competition draught horses. The spectrum of upper airway conditions identified in exercising draught horses supports the use of overground endoscopy as a diagnostic technique and could influence treatment considerations.
