概括

无屏蔽RADPAD显著减少模拟过程中的散射辐射. 当与常规相结合时,它为外科医生提供了卓越的保护,尤其是头部和手臂.

科学领域:

医学物理医学物理
外科手术的安全性
辐射保护辐射保护

背景情况:

使用光镜的手术程序使医疗保健专业人员暴露在散射辐射中.
传统的屏蔽 (LATS) 提供了重要的保护,但在覆盖所有关键区域方面存在局限性.
需要新的屏蔽解决方案来提高外科医生的安全性,而不会增加重量负担.

研究的目的:

评估无辐射屏蔽RADPAD在模拟皮肤穿透性瘤切除 (PCNL) 过程中减少散射辐射的有效性.
为了比较RADPAD与传统的围和甲状腺屏蔽 (LATS) 的保护能力.
评估RADPAD与LATS结合的额外好处,以提供全面的外科医生保护.

主要方法:

模拟PCNL使用放射性幻影和人形外科医生.
在七个关键的外科医生位置使用实时剂量计测量辐射剂量 (μSv).
屏蔽策略的比较:LATS单独,RADPAD单独和LATS与RADPAD,与基线 (没有屏蔽) 相比.

主要成果:

仅靠LATS就能在屏蔽区域减少95%以上的伤害,但无法保护头部,前臂和腿部.
单独使用RADPAD可显著减少大多数部位的辐射,除了腿部.
将LATS与RADPAD相结合提供了最大的辐射减少,明显优于LATS单独用于头部,骨盆和前臂.

结论:

拉德帕德 (RADPAD) 是一种有效的无屏蔽,可以增强外科医生对散射辐射的保护.
将RADPAD与传统LATS相结合,可以在不增加重量的情况下为头部和手臂提供更好的保护.
可能需要进一步的研究来解决PCNL手术期间腿部的辐射保护问题.

关键词:

光镜是指光镜.通过皮肤进行nephrolithotomy.暴露于辐射的辐射暴露.辐射保护辐射保护手术窗是指外科的窗.尿病是一种尿病.

Personal Protective Equipment

Personal Protective Equipment

Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current

An applied magnetic field causes the electrons present in the molecule to circulate, setting up a local diamagnetic current within the molecule. The local diamagnetic current arising from circulating sigma-bonding electrons induces a magnetic field, Blocal that opposes the applied magnetic field, B0. The effective magnetic field experienced by these nuclei is given by the difference between the applied and local magnetic fields in a phenomenon called local diamagnetic shielding. Essentially,...
