两种弹丸式注射方法在肾检查对比的分析

目的研究弹丸注射的方法，提高弹丸的注射成功率。方法分别选择符合条件的病人48例，经临床诊断为慢性肾功能不全、慢性肾功能不全伴高血压、尿毒症病人，先采取用头皮针连接有0．9％NS（盐水）注射器5ml穿刺静脉，穿刺静脉成功试行弹丸注射0．9％NS（盐水），试行成功再接肾显像剂弹丸注射。结果经过两组病人弹丸注射的比较，观察组的弹丸注射成功率为100％，对照组弹丸注射成功率为94％。结论观察组的弹丸注射方法与对照组比较，观察组的注射方法能保证弹丸注射显像剂的成功，使当天的检查完成，具有社会效益，值得推广应用。

Two tiny injections method in renal MRI

Objective To study tiny injection for raising its success rate. Methods 48 patients corresponding to the selective criteria were diagnosed with of chronic renal insufficiency, chronic renal insufficiency uremia and hypertension. Scalp needle was connected with a 5 ml 0.9% NS （ saline ） syringe vein puncture, puncture vein successfully piloted projectile injection 0.9%NS （ saline ）, then renal imaging agent tiny injection. Results The successful rate of tiny injection was 100% in the observation group and 94% in the control group. Conclusions The injection method of the observation group can ensure the success of the injection of imaging agent, so that the check is complete on the same day. Methods in the observation group has social benefit, can be popularized clinically.
