Abstract
Programmable variable pressure valves were introduced in the 1980s, providing a non-invasive solution to post-operative alterations of the valve opening pressure to address problems of under or overdrainage. Since their increased use in the treatment of hydrocephalus, there have been case reports of unintentional alterations of the valve opening pressure following exposure to magnetic fields in everyday environments, from televisions to rollercoasters. Here we describe two cases of patients' programmable valves being altered following audiology assessments. We subsequently discuss some of the available research on the safety of these valves in various magnetic field strengths, alongside interim and updated recommendations made by the British Society of Audiologists with regards to testing of children with programmable shunts in place.
可编程变压阀于 20 世纪 80 年代问世，为术后改变瓣膜开放压力以解决引流不足或引流过度问题提供了一种非侵入性解决方案。自从可调节变压阀越来越多地用于治疗脑积水以来，有病例报告称，在暴露于从电视机到过山车等日常环境的磁场后，瓣膜开启压力会发生无意改变。在此，我们描述了两例患者的可编程瓣膜在听力评估后被改变的病例。随后，我们将结合英国听力学家协会（British Society of Audiologists）就儿童可编程分流术测试提出的临时和最新建议，讨论有关这些瓣膜在不同磁场强度下安全性的一些现有研究。
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
