摘　　要：目的:了解硬膜外麻醉单次快速给药时药物的弥散性及方向性。方法:特施行硬膜外麻醉的患者随机分两组,实验组快速给予麻醉药及显影剂(30 ml/s),对照组常规给予麻醉药(附加显影剂),药物弥散性及方向由放射自显影法探测。结果:实验组麻醉平面增加约30％,阻滞确切,与对照组有显著性差异(P<0.01),并发现药物流动方向与穿刺针斜面方向有关。结论:硬膜外麻醉单次快速给药较传统方法更为有效,不良反应更少,药物流动方向与穿刺针斜面同向。Objective: To study the dispersion and direction in single rapid injection during epidural anesthesia. Methods: All patients were selected randomly when underwent epidural anesthesia,local anesthetic and tracer were injected into epidural space(30 ml/sec) .while the controlled group followed conventional procedure( added by tracer). The dispersion and direction were detected by autoradiography. Results: Rapid injection increases block plane about 30% , there is significant difference between two groups( P<10.01) . The direction minister relates to the bevel of puncture needle. Conclusions:single rapid injection during epidural anesthesia is more effectiveness untoward reaction than conventional method, the direction of which attributes to the bevel of puncture needle.
