Abstract：
OBJECTIVE: To determine whether student involvement in intravenous catheter (IVC) placement increases the risk for complications and to report the rate and types of complications associated with IVCs in adult horses in a university teaching hospital.
METHODS: 455 IVCs placed in 394 horses.
METHODS: Data relevant to IVC placement and removal were retrieved from an electronic medical record search including records of adult horses from January 1 to December 31, 2022. Data retrieved from records included the role of the individual who prepared the site and placed the IVC, site of IVC placement, and type of IVC. The reason for removal of the IVC and presence or absence of detectable changes within the vein at the time of removal were documented in addition to clinical data, allowing for classification of each case. Data were reviewed retrospectively, and statistical analyses were performed using mixed-effects logistic regression models. Significance was set at P ≤ .05.
RESULTS: The overall rate of complications was 15.6%, and the most common type of complication was swelling of the vein. Students were involved in 87 of 455 IVC site preparations and placements, and there were no statistically significant differences in complication rates between IVC sites prepared or placed by veterinary students versus nonstudent personnel.
CONCLUSIONS: Veterinary personnel and clients may be hesitant to allow student involvement in IVC placement in horses, but these data suggest that student involvement does not increase the risk of IVC complications.

摘要：
目的：确定学生参与静脉导管（IVC）放置是否会增加并发症的风险，并报告在大学教学医院的成年马中与IVC相关的并发症的发生率和类型。
方法：在394匹马中放置455个IVC。
方法：从电子病历搜索中检索与IVC放置和移除相关的数据，包括2022年1月1日至12月31日的成年马记录。从记录中检索到的数据包括准备站点并放置IVC的个人的角色，IVC放置部位，和IVC的类型。除临床数据外，还记录了去除IVC的原因以及在去除时静脉内是否存在可检测的变化。允许对每种情况进行分类。数据进行了回顾性审查，并使用混合效应逻辑回归模型进行统计分析。显著性设定为P≤0.05。
结果：并发症的总发生率为15.6%，最常见的并发症类型是静脉肿胀。学生参与了455个IVC站点准备和安置中的87个，由兽医学生准备或安置的IVC点与非学生人员的并发症发生率无统计学显著差异.
结论：兽医人员和客户可能会犹豫是否允许学生参与马的IVC安置，但这些数据表明,学生参与不会增加IVC并发症的风险.
