目的探讨静脉留置针在核素显像中的应用价值。方法选择2012年10月-2013年4月行单光子发射计算机断层成像术全身骨显像和肾动态显像检查的患者120例,将其随机分为静脉留置针组(留置针组)和传统钢针组(对照组),每组60例。分别观察两组患者一次性静脉穿刺成功率、显像剂推注渗漏发生率、注射器内显像剂残留剂量、注射人员接触放射性药物时间等。结果留置针组一次性穿刺成功率与对照组相近(P>0.05);在药物推注过程中,留置针组均未发生渗漏现象,而对照组的37例全身骨显像患者则发生4例显像剂渗漏,23例肾动态显像患者发生3例显像剂渗漏,但两组比较差异均无统计学意义(P>0.05);而留置针组显像剂推注过程中注射器内残留剂量低于对照组,注射人员接触放射性药物时间亦低于对照组(P<0.05)。结论用静脉留置针进行静脉穿刺能够有效避免放射性显像剂渗漏,减少注射器中放射性显像剂的残留剂量,可以提高动态扫描一次性成功率及诊断准确性和工作效率;同时减少注射人员放射性接触时间,达到优化防护。
Objective To investigate the value of venous indwelling needle in radionuclide imaging. Methods A total of 120 patients underwent single photon emission computed tomography (BMA) and renal dynamic imaging from October 2012 to April 2013 were randomly divided into venous indwelling needle group (indwelling needle group) and traditional Needle group (control group), 60 cases in each group. The success rate of one-time venipuncture, the incidence of imaging bolus leakage, the residual dose of imaging agent in the syringe and the time of injecting human exposure to radiopharmaceuticals were observed respectively. Results The success rate of one-time puncture in indwelling needle group was similar to that in control group (P> 0.05). During the bolus injection, no leakage occurred in the indwelling needle group, while in the control group, 37 patients with whole body bone imaging developed 4 3 cases of renal dynamic imaging in patients with imaging leakage occurred in 3 cases, but there was no significant difference between the two groups (P> 0.05); while indwelling needle group imaging agent during the bolus The residual dose in the syringe was lower than that in the control group, and the time of injecting radiopharmaceuticals in the injecting group was also lower than that of the control group (P <0.05). Conclusion Intravenous catheterization of venipuncture can effectively prevent the leakage of radioactive imaging agent and reduce the residual dose of radioactive imaging agent in the syringe, which can improve the success rate of one-time dynamic scanning and the diagnostic accuracy and working efficiency; at the same time, reduce the radioactive Contact time, to optimize the protection.
