    Abstract:
    Anaesthesiologists are increasingly involved in nonoperating room anaesthesia (NORA) for fluoroscopic procedures. However, the radiation exposure of medical staff differs among NORA settings. Therefore, we aimed to investigate the radiation environment generated by fluoroscopic endoscopic retrograde cholangiopancreatography (ERCP) and the radiation exposure of anaesthesiologists. The dose area product (DAP), radiation entrance dose (RED), and fluoroscopy time (FT) according to the procedures and monthly cumulative radiation exposure were analysed at two sites (neck and wrist) from 363 procedures in 316 patients performed within 3 months. The total RED and DAP were 43643.1 mGy and 13681.1 Gy cm2, respectively. DAP and RED (r = 0.924) were strongly correlated and DAP and FT (r = 0.701) and RED and FT (r = 0.749) were moderately correlated. The radiation environment per procedure varied widely, DAP and RED per FT were the highest during stent insertion with esophagogastroduodenoscopy. Monthly cumulative deep dose equivalents at the wrist and neck ranged between 0.31-1.27 mSv and 0.33-0.59 mSv, respectively, but they were related to jaw thrust manipulation (r = 0.997, P = 0.047) and not to the radiation environment. The anaesthesiologists may be exposed to high dose of radiation in the ERCP room, which depends on the volume of procedures performed and perhaps the anaesthesiologists' practice patterns.
