摘要
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 application value of the intravenous indwelling needle in radionuclide imaging examination. Methods A total of 120 patients underwent single photon emission computed tomography for bone and kidney dynamic imaging between October 2012 and April 2013 were randomly divided into group injected by venous indwelling needle （observagtion group） and group injected by traditional steel needle （control group）, with 60 cases in each. We calculated the one-time success rate of venipuncture, the leakage rate of intravenous injection, residual radioactive dosage within the syringe and average exposure time of medical staff to radionuclide in the two groups of patients. Results The one-time success rate of venipuncture in observation group was similar to that in the control group （P 〉 0.05）. During the injection, no leakage was found in observation group, while 4 leakage in 37 patients underwent bone imaging and 3 leakage in 23 patients underwent kidney dynamic imaging in the control group were found; there was no significant difference between the two groups （P 〉 0.05）. The residual radioactive dosage within the syringe in observation group was lower than that in the control group, and the exposure time of medical staff to radionuclide in observation group was also lower than that in the control group （P 〈 0.01）. Conclusions Intravenous indwelling needle for venous puncture can avoid leakage of radioactive imaging agent, reduce the residual radiological dosage within the syrings, increase the one-time puncture success rate and imaging resolution of dynamic scan, and improve the diagnostic accuracy and work efficiency effectively. Besides, the intravenous indwelling needle technique can reduce average exposure time of medical staff to radionuclide, acheaving the goal of optimized protection.
