摘　　要：目的比较直型留置针注射与传统静脉直接注射对锝99m-喷替酸盐注射液(^(99m)Tc-DTPA)肾动态显像“弹丸”注射成功率的影响,以及两种“弹丸”注射法的灌注曲线形态和人均成本差异,探讨一次性直型留置针的临床应用可行性。方法选取2019年4月至2020年10月于中国医学科学院肿瘤医院深圳医院行^(99m)Tc-DTPA肾动态显像检查肾小球滤过率(GFR)的128例肿瘤患者,根据入院时间先后分为对照组(2019年4-11月)与观察组(2019年12月至2020年10月),每组64例。对照组采用静脉直接“弹丸”注射,观察组采用直型留置针“弹丸”注射,比较两组“弹丸”注射成功率、灌注曲线形态及检查的人均成本。结果观察组“弹丸”注射成功率高于对照组,差异有统计学意义(P<0.05)。对照组6例注射失败患者再重复做1次检查,两组峰值类型比较,差异有统计学意义(P<0.05);两组图像质量比较,差异无统计学意义(P>0.05)。观察组人均成本低于对照组,差异有统计学意义(P<0.05)。结论直型留置针提高了^(99m)Tc-DTPA肾动态显像“弹丸”注射成功率,且合格图像与传统静脉直接注射法相仿,此外,因为减少了注射失败患者的二次检查次数,人均成本低于传统静脉直接注射法。Objective The impact of straight indwelling needle injection and traditional direct intravenous injection to the projectile injection success rate of ^(99m) Tc-diethylenetriaminepentaacetic acid(^(99m) Tc-DTPA)in renal dynamic imaging and the differences of perfusion curve shape and cost per capita of the two projectile injection methods were compared to explore the clinical practicability of straight indwelling needle.Methods A total of 128 patients who received ^(99m) Tc-DTPA renal dynamic imaging examination to obtain glomerular filtration rate(GFR)in Shenzhen Hospital of Cancer Hospital,Chinese Academy of Medical Sciences from April 2019 to October 2020 were included.They were divided into a control group(from April to November in 2019)and an observation group(from December 2019 to October 2020)according to the admission time,with 64 cases in each group.The control group adopted direct intravenous projectile injection,while the observation group adopted intravenous indwelling needle projectile injection.Then the projectile injection success rate,the perfusion curve shape and the examination cost per capita were compared between the two groups.Results The projectile injection success rate of the observation group was higher than that of the control group,with statistically significant difference(P<0.05).The 6 patients in the control group who had failed injection were examined again,when the type of peak value of the two groups were compared,the difference was statistically significant(P<0.05);while there was no significant difference in image quality between the two groups(P>0.05).The per capita cost of the observation group was lower than that of the control group,with statistically significant difference(P<0.05).Conclusion The application of straight indwelling needle improved the projectile injection success rate of ^(99m) Tc-DTPA renal dynamic imaging,and the image quality was similar to that of the traditional direct intravenous injection method.Besides,resulting from reducing the second examination of f
