目的探讨心血管介入诊断与治疗时患者的受照剂量、剂量分布及其对外周血角的影响。方法将热释光剂量计放置于接受心血管介入诊断或治疗术的患者的甲状腺、眼晶体、左胸、下膜部及下肢等部位,以测定各部位受照剂量;同时于术前及介入术后一天分别检查患者的外周血象。结果心血管介入术患者的吸收剂量以左胸部最高,甲状腺次之,然后依次为眼晶体、下腹部及下肢。其外周血象未见明显变化。结论心血管介入术中应加强对患者胸部、甲状腺及晶状体的辐射防护,且尽量减少其暴露时间。
Objective To investigate the dose, dose distribution and influence on peripheral blood angle of patients during the diagnosis and treatment of cardiovascular intervention. Methods The thermoluminescence dosimeter was placed in the thyroid, the lens of the eye, the left chest, the inferior diaphragm and the lower limbs of patients undergoing cardiovascular interventional diagnosis or treatment to determine the dose of each part. At the same time, One day after surgery, the patient’s peripheral blood was examined. Results In patients undergoing cardiovascular intervention, the absorbed dose was highest in the left chest, followed by the thyroid, followed by ocular crystals, lower abdomen and lower extremities. No significant changes in peripheral blood. Conclusions Radiation protection of the chest, thyroid and lens in patients with cardiovascular intervention should be strengthened and the exposure time should be minimized.
