BACKGROUND
Intraosseous access has been used increasingly with proven efficacy in emergent situations for adults when intravenous access could not be obtained.
OBJECTIVE
Our aim was to demonstrate if tibial intraosseous (IO) is an effective route for iodinated contrast administration and pulmonary vasculature visualization.
CASE REPORT
We report on an obtunded patient requiring a computed tomography angiogram to help with diagnosis and tibial IO was the only viable access appropriate to withstand the pressure of a computed tomography iodinated contrast load. Tibial IO access was used successfully for administration of iodinated contrast to evaluate for massive pulmonary embolism in an obtunded patient in extremis secondary to cardiovascular instability.
CONCLUSIONS
The pulmonary arteries were opacified and demonstrated a high-quality CT angiogram can be done via tibial IO device.
背景
当无法获得静脉通路时，骨内通路在成人紧急情况下的使用越来越多，且已证实其有效性。
目的
我们的目的是证明胫骨骨内（IO）是否是注射碘化造影剂和观察肺血管系统的有效途径。
病例报告
我们报告了一名意识不清的患者，需要进行计算机断层血管造影以辅助诊断，而胫骨IO是唯一能够承受计算机断层碘化造影剂负荷压力的可行通路。胫骨IO通路成功用于为一名因心血管不稳定而处于危急状态的意识不清患者注射碘化造影剂，以评估大面积肺栓塞。
结论
肺动脉显影，表明通过胫骨IO装置可以完成高质量的CT血管造影。
