Exploration of safety evaluation and optimization of improved bullet injection in renal dynamic examination
改良弹丸式注射在肾动态检查中的安全性评估与优化探究

摘要

目的 观察分析改良弹丸式注射在肾动态检查中的安全性评估的临床效果和应用价值。方法 将2024年1月-7月所有在我科行肾动态显像+肾小球滤过率（GFP）测定的患者作为研究对象，随机数字分为对照、实验两个小组。分别实施生理盐水接上头皮针后用直接注射方式，改良式注射。收集分析注射效果。结果 相比对照组，实验组患者腹主动脉显影时间更短（P＜0.05）；两组患者腹主动脉显影后肾显影时间、穿刺点渗漏率没有显著差异（P＞0.05）。结论 两种注射方式提高了肾动态显像“弹丸”注射成功率。改良弹丸式注射可以更快显示出腹主动脉，且注射失败患者的二次检查次数减少，人均成本低于传统静脉直接注射法。有较高应用价值。

Abstract

Objective Observation and analysis of the clinical efficacy and application value of the safety evaluation of improved pellet injection in renal dynamic examination.
Methods All patients who underwent renal dynamic imaging and glomerular filtration rate (GFP) measurement in our department from January to July 2024 were selected as the study subjects and randomly divided into two groups: control group and experimental group. Perform direct injection of physiological saline and scalp needle separately, using an improved injection method. Collect and analyze injection effects.
Results Compared with the control group, the experimental group had a shorter abdominal aorta visualization time (P < 0.05); there were no significant differences between the two groups in terms of renal visualization time after abdominal aorta visualization and puncture point leakage rate (P > 0.05).
Conclusion   Two injection methods improved the success rate of "bullet" injection in renal dynamic imaging. Improved bullet injection can display the abdominal aorta faster, reduce the number of secondary examinations for patients with injection failure, and lower the per capita cost compared to traditional intravenous direct injection method. Has high application value.
