Free coelomic fluid can be a physiologic or pathologic finding in snakes. In this study, ultrasonography was used to assess the presence, volume, and type of coelomic fluid in 18 (16 females, 2 males) clinically healthy corn snakes () using a semiquantitative scoring system. Each snake was divided into five equal regions (R1-R5) by length (from rostrum to vent) and fluid volume was scored on a scale of 0 to 4. Coelomic fluid was sampled when possible and cytologic analysis was performed. The majority of snakes (16/18) were found to have some degree of free coelomic fluid. The coelomic fluid samples that were collected (= 6) were classified as transudates, acellular or primarily lymphocytic. Fluid was most likely to be found in R3 compared with all other regions and least likely to be found in R1 compared with R2, R3, and R4. A higher score of volume was found in R3 compared with R1 and R5. This study describes the distribution and abundance of coelomic fluid in snakes, as well as a method for point of care ultrasound (POCUS) in this species.
游离体腔液在蛇类中可能是一种生理或病理表现。在这项研究中，我们使用半定量评分系统，对 18 条临床健康玉米蛇（）的体腔液的存在、体积和类型进行了超声评估（16 条雌蛇，2 条雄蛇）。每条蛇按长度（从吻端到泄殖腔）分为五个相等的区域（R1-R5），并按 0 到 4 的评分标准对体腔液体积进行评分。当可能时采集体腔液样本，并进行细胞学分析。大多数蛇（16/18）都有一定程度的游离体腔液。收集的体腔液样本（=6）被分类为渗出液、无细胞或主要为淋巴细胞。与其他所有区域相比，R3 中最有可能发现液体，与 R2、R3 和 R4 相比，R1 中最不可能发现液体。与 R1 和 R5 相比，R3 中的体积评分更高。本研究描述了蛇类体腔液的分布和丰度，以及该物种即时护理超声（POCUS）的方法。
