The study objective was to examine the effect of the Bleeper Sv radiation monitoring device on operator and patient radiation exposure during cardiac catheterization. The Bleeper Sv device provides real-time operator dose reporting through auditory feedback. Device feedback enables the operator to take protective measures, such as using radiation only when necessary, repositioning the camera, stepping farther away from the source, or adjusting the lead shielding.\u003C\/p\u003E\n         \u003Cp id=\u0022p-4\u0022\u003EThe study included patients undergoing clinically indicated coronary angiography or percutaneous coronary intervention (PCI). A total of 505 patients were randomized to the Bleeper Sv (n = 253) or to the control group (n = 252). The primary end point was operator radiation exposure. Secondary end points were patient radiation exposure, fluoroscopy time, and contrast volume.\u003C\/p\u003E\n         \u003Cp id=\u0022p-5\u0022\u003ESimilar proportions of patients in both groups received diagnostic, PCI, and diagnostic + PCI procedures.

The second operator radiation exposure in the Bleeper Sv group was reduced versus control for diagnostic procedures (0.4 vs 0.7 mrem; p \u0026lt; .001), PCI (0.4 vs 0.6 mrem; p = .197), and both (0.5 vs 0.07 mrem; p \u0026lt; .001), for a 29% relative reduction in overall radiation exposure.\u003C\/p\u003E\n         \u003Cp id=\u0022p-7\u0022\u003EThere were no significant differences between the Bleeper Sv and control groups in patient air kinetic energy released per unit mass (kerma) for diagnostic procedures (p = .189), PCI (p = .631), or both (p = .153). Nor were significant differences observed between the Bleeper Sv and control groups in patient dose area product radiation dose for diagnostic procedures (p = .269), PCI (p = .511), or both (p = .125).

Additionally, the trial was not adequately powered for differences in patient radiation exposure and did not include a formal protocol for reducing radiation exposure apart from Bleeper Sv use. Dr. Christopoulos concluded that use of the Bleeper Sv device during cardiac catheterization resulted in a 29% to 36% decrease in operator radiation exposure.\u003C\/p\u003E\n      \u003C\/div\u003E\u003Cul class=\u0022copyright-statement\u0022\u003E\u003Cli class=\u0022fn\u0022 id=\u0022copyright-statement-1\u0022\u003E\u00a9 2014 MD Conference Express\u00ae\u003C\/li\u003E\u003C\/ul\u003E\u003Cspan class=\u0022highwire-journal-article-marker-end\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Cspan id=\u0022related-urls\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Ca href=\u0022http:\/\/mdc.sagepub.com\/content\/14\/13\/12.1.abstract\u0022 class=\u0022hw-link hw-link-article-abstract\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView Summary\u003C\/a\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n  \n  \u003C\/div\u003E\n\u003C\/div\u003E\n  \u003C\/div\u003E\n\u003C\/div\u003E\n\u003C\/div\u003E\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_openurl.js?nzoyy1\u0022\u003E\u003C\/script\u003E\n\u003C\/body\u003E\u003C\/html\u003E"}
