摘要
目的:探讨肾上腺素在阴茎根部阻滞麻醉中的作用及其安全性。方法:分别以1ml和5ml注射器,7号针头进行水平位和垂直位的肾上腺素滴注实验。用1ml注射器,在2%利多卡因5ml中垂直滴入一滴1‰盐酸肾上腺素,将其浓度控制在1:500000。A组和B组分别于2点和10点45°进针行阴茎根部阻滞后,行袖套法包皮环切术或传统包皮环切术。结果:使用加入肾上腺素的2%利多卡因行阴茎根部阻滞麻醉的A组患者术中出血(15±3)ml,明显少于B组(27±5)ml(P<0.05),而且麻醉时间由40min延长至90min。结论:1ml注射器滴液时的标准差较小,可以有效地控制麻药中肾上腺素的浓度以保证其安全性。采用加入1:500000肾上腺素的2%利多卡因行阴茎根部阻滞,可以明显延长麻醉时间,提高麻醉效果,减少包皮环切术的术中出血量,因而可取得良好的临床效果。
Objective To evaluate the effect and safety of adrenaline in penile root block. Methods The experiment was took to count how many drops of lml adrenaline dripped by lml and 5ml injector with 7^# needle individually in horizontal and vertical position. The concentration of adrenaline is controlled in 1：500 000 if one drop of 1%o adrenaline is added in 5ml 2%lidocaine by lml injector with 7^# needle in vertical position. After the dorsal penile nerve was blocked in 2＇and 10＇clock in two groups, sleeve circumcision or traditional circumcision was operated. Results The amount of intraoperative hemorrhage was （15±3）ml in group A and （27±5）ml in group B （P less than 0.05） and the time of anesthesia is prolonged from 40 minutes to 90 minutes. Conclusions The standard deviation of drop experiment of 1ml injector with 7^# needle in vertical position is small enough to control the concentration of adrenaline steadily to assure the safety of adrenaline. The time of anesthesia was prolonged and the amount of intraoperative hemorrhage was reduced in circumcision by penile root block with 2%lidocaine and 1：500 000 adrenaline.
