OBJECTIVE
To evaluate the use of auricular vein catheters (AVC) in cattle in a clinical setting.
DESIGN
Case series.
ANIMALS
57 cattle.
PROCEDURE
68 AVC were placed in cattle for the administration of drugs or rehydration fluids. Catheter size, quantity of fluids administered, duration of administration, drugs administered, duration of catheter maintenance, and problems were recorded.
RESULTS
The AVC ranged in size from 20 to 14 gauge, with the latter being the predominate size. A maximum flow rate of 7.7 L/h was achieved, and the flow rate was satisfactory in all but 1 case. The maximum duration of maintenance was > 96 hours. Problems occurred in 29 of 68 (43%) catheterizations; the most frequent problem was occlusion of the catheter, which occurred 16 times (24%). No serious complications occurred.
CLINICAL IMPLICATIONS
Auricular vein catheters were a convenient, safe, and low-cost alternative to jugular vein catheters.
目的
评估耳静脉导管（AVC）在临床环境中用于牛的情况。
设计
病例系列。
动物
57头牛。
程序
将68根AVC置于牛体内用于给药或补液。记录导管尺寸、给药液体量、给药持续时间、给药药物、导管维护持续时间及问题。
结果
AVC尺寸范围为20至14号，后者为主要尺寸。实现了最高7.7 L/h的流速，除1例情况外流速均令人满意。最长维护持续时间>96小时。68次置管中有29次（43%）出现问题；最常见的问题是导管堵塞，发生了16次（24%）。未发生严重并发症。
临床意义
耳静脉导管是颈静脉导管方便、安全且低成本的替代选择。
