Transfemoral Transcatheter Aortic Valve Implantation (TAVI) has become a standard therapy for patients with aortic valve stenosis. Fluoroscopic imaging is essential for TAVI with the anesthesiologist's workplace close to patient's head side. While the use of lead-caps has been shown to be useful for interventional cardiologists, data are lacking for anesthesiologists.
A protective cap with a 0.35 lead-equivalent was worn on 15 working days by one anesthesiologist. Six detectors (three outside, three inside) were analyzed to determine the reduction of radiation. Literature search was conducted between April and October 2018.
In the observational period, 32 TAVI procedures were conducted. A maximum radiation dose of 0.55 mSv was detected by the dosimeters at the outside of the cap. The dosimeters inside the cap, in contrast, displayed a constant radiation dose of 0.08 mSv.
The anesthesiologist's head is exposed to significant radiation during TAVI and it can be protected by wearing a lead-cap.
经股动脉主动脉瓣置换术（TAVI）已成为主动脉瓣狭窄患者的标准治疗方法。在 TAVI 中，需要进行透视成像，麻醉师的工作场所靠近患者头部。虽然已经证明铅帽对于介入心脏病学家很有用，但对于麻醉师的数据却缺乏。
一名麻醉师在 15 个工作日内佩戴了一个带有 0.35 铅当量的防护帽。分析了六个探测器（三个在外部，三个在内部），以确定辐射的减少量。文献检索在 2018 年 4 月至 10 月之间进行。
在观察期间，进行了 32 例 TAVI 手术。帽子外部的剂量计检测到最大辐射剂量为 0.55 mSv。相比之下，帽子内部的剂量计显示出恒定的 0.08 mSv 辐射剂量。
在 TAVI 过程中，麻醉师的头部会受到大量辐射，通过佩戴铅帽可以对其进行保护。
