The utilization of spinal cord stimulation (SCS) to treat intractable pain has increased substantially in recent years. Integral to this therapy, the fluoroscope assists with requisite mapping protocols during trialing procedures to identify topographical dermatomal representations of spinal segments, and its use demands measurements of radiation exposure. However, such data is not found in the literature.
The aim of this study was to report on radiation exposure during percutaneous SCS trialing procedures.
An observational study.
A non-university out-patient Interventional Pain Management practice in the United States.
Fluoroscopy time from 110 SCS trialing procedures performed in a non-university, outpatient setting was studied retrospectively. Summary statistics were reported for all procedures collectively, as well as for lead arrangement and location. The interventional spine team carried out all procedural cases with the same mobile C-arm fluoroscopy system. Incident air kerma was evaluated by simplistic modeling.
Mean total fluoroscopy time was 133.4 s with a standard deviation of 84.8 s, and the mean percentage of time allocated to pulsed fluoroscopy was 31.9%. Fluoroscopy time for the most common lead arrangement/location, neural canal dual leads/low-thoracic (n=87), ranged from 28.5 s to 387.4 s. Incident air kerma was 1.8-43.7 mGy.
A preliminary report with a sample size of 110.
Various lead placement options are available to the spinal interventionalist to treat pain with SCS. Our data set provides first steps to obtain benchmark reference estimates on fluoroscopy times and radiation exposure during SCS trialing procedures/spinal segment mapping. Fluoroscopy times for such interventions may be considerable when compared to more commonly performed pain medicine procedures; however, skin injury is improbable.
近年来，脊髓刺激（SCS）治疗难治性疼痛的应用显著增加。这种治疗的重要组成部分是透视仪，它在试验过程中协助必要的绘图协议，以确定脊髓节段的地形皮节代表，并且其使用需要测量辐射暴露。然而，文献中没有这样的数据。
本研究旨在报告经皮 SCS 试验过程中的辐射暴露情况。
观察性研究。
美国非大学门诊介入疼痛管理实践。
回顾性研究了在非大学门诊环境中进行的 110 次 SCS 试验程序的透视时间。所有程序的汇总统计数据均有报告，包括导联排列和位置。介入脊柱团队使用相同的移动 C 臂透视系统进行所有程序病例。通过简化模型评估入射空气比释动能。
平均总透视时间为 133.4 秒，标准差为 84.8 秒，脉冲透视时间的平均百分比为 31.9%。最常见导联排列/位置（n=87）的神经管双导联/低胸导联的透视时间范围为 28.5 秒至 387.4 秒。入射空气比释动能为 1.8-43.7 mGy。
初步报告，样本量为 110。
脊髓介入治疗师有多种导联放置选择可用于治疗 SCS 疼痛。我们的数据组提供了初步的基准参考估计，用于在 SCS 试验程序/脊髓节段映射期间获得透视时间和辐射暴露的数据。与更常见的疼痛医学程序相比，此类干预的透视时间可能相当长；然而，皮肤损伤不太可能发生。
