Abstract:
Objective To investigate the radiation doses in different areas around the operation table during intervention procedure and to study the effect of X-ray protection equipments.Methods A total of 37 procedures(12 diagnostic cardiac angiographies and 25 percutaneous coronary intervention therapy) were investigated.The detection of X-ray was carried out in 2 separate groups.The first group included the operators,assistants and nurses.There were 6 detecting points on each person resulting in a total of 18 detecting points.The second group consisted of 10 detecting points on different areas of the patients and the protecting lead shields around.The measurement of X-ray doses was performed by the specialist from the radiation protection agency.Results The doses of X-ray was directly proportional to the duration of exposure.The X-ray doses varied among the 28 detecting points.The highest amount of radiation were detected on the left arm of the operator and on the left axilla and the back of the patients.Above 90% of radiation could be protected by lead shields and lead clothes.Conclusion Lead protective products available at precent are efficient in protecting radiation exposure during cardiovascular intervention procedures.More attention still need to be paid to certain highly exposed areas.
