Intraosseous (IO) catheterization enables rapid access to systemic circulation in critical patients. A battery-powered IO device (BPIO) utilized in veterinary practice is reliable in facilitating IO catheter placement. A new spring-powered IO device (SPIO) has been developed for people but has not been tested in veterinary patients. The goal of our study was to compare placement characteristics and flow rates achieved with the BPIO compared to the SPIO in animals when operated by novice users.
Six veterinary students performed 72 catheterizations in the humeri and tibias of 12 dog and 6 cat cadavers. The user, cadaver, device, and site of placement were randomized. Flow rates were determined by three-minute infusions.
In dogs, overall success rates (50% BPIO, 46% SPIO; = 0.775) and flow rates based on location were similar between devices. Successful placement was faster on average with the BPIO (34.4 s for BPIO and 55.0 s for SPIO, = 0.0392). However, time to successful placement between devices was not statistically significant based on location (humerus: 34.7 s for BPIO and 43.1 s for SPIO, = 0.3329; tibia: 33.3 s for BPIO and 132.6 s for SPIO, = 0.1153). In cats, success rates were similar between devices (16.7% for BPIO and 16.7% for SPIO, = 1.000), but limited successful placements prevented further analysis.
This is the first study to examine the use of the SPIO in animals, providing preliminary data for future IO studies and potential applications for training in the clinical setting.
骨内（IO）置管能够在危急患者中快速建立体循环通路。兽医实践中使用的电池驱动骨内装置（BPIO）在促进骨内置管方面是可靠的。一种新型弹簧驱动骨内装置（SPIO）已被开发用于人类，但尚未在兽医患者中进行测试。我们研究的目的是比较新手用户操作时，动物使用BPIO和SPIO的置管特性及流速。
六名兽医专业学生在12只犬和6只猫的尸体的肱骨和胫骨上进行了72次置管。用户、尸体、装置和置管部位均随机分配。通过三分钟输注确定流速。
在犬中，两种装置的总体成功率（BPIO为50%，SPIO为46%；P = 0.775）以及基于置管部位的流速相似。BPIO平均置管成功速度更快（BPIO为34.4秒，SPIO为55.0秒，P = 0.0392）。然而，基于置管部位，两种装置之间成功置管的时间在统计学上无显著差异（肱骨：BPIO为34.7秒，SPIO为43.1秒，P = 0.3329；胫骨：BPIO为33.3秒，SPIO为132.6秒，P = 0.1153）。在猫中，两种装置的成功率相似（BPIO为16.7%，SPIO为16.7%，P = 1.000），但成功置管次数有限，无法进行进一步分析。
这是第一项研究SPIO在动物中应用的研究，为未来骨内研究提供了初步数据，并为临床环境中的培训提供了潜在应用。
