腰麻注药速度及部位对肠回纳术麻醉的影响

Spinal Injection Speed and Location Back to the Influence of Intestinal Sodium Anesthesia

目的分析腰麻不同注药速度及部位对麻醉的影响。方法 150例ASAⅠ-Ⅱ级回结肠造瘘术后肠回纳患者,按注药速度10、15、20 s随机均分为A、B、C三组,每组50例;各组再按注药部位L2-3、L3-4不同均分为两亚组,各亚组25例。观察各组麻醉效果和不良反应。结果腰麻注射速度和部位不同,麻醉效果和不良反应随之而变（P〈0.05）。结论肠回纳术患者,以L2-3穿刺15 s注入0.5%左布比卡因2 m L安全优效,可控性好。

Objective Analysis of the impact of spinal anesthesia with differentinjection velocity and position on anesthesia. Methods 150 cases ofASAⅠ-Ⅱ grade to colostomy patients after returning, the injection rate of 10, 15, 20 s were randomly divided into A, B, C three groups, each group had 50cases; group L2.3, according to the injection site L3-4 was divided into two subgroups, each subgroup of 25 cases. To observe the anesthetic effects and adverse reactions. Results Spinal injection velocity and position of different, anesthesia effect and adverse reaction of change（P〈0.05）. Conclusion Intestinal returning patients, injection of 0.5% levobupivacaine 2 mL security superiority to L2-3 puncture 15 s, good controllability.
