摘要
目的探究小剂量不同浓度罗哌卡因麻醉在老年膝髋关节置换中的效果。方法 120例择期行人工膝髋关节置换术患者,采用随机数字表法分为麻醉1组、麻醉2组及麻醉3组,各40例。麻醉1组、麻醉2组及麻醉3组分别给予浓度为0.15%、0.25%及0.50%的3 ml罗哌卡因穿刺麻醉。记录并比较三组患者的感觉阻滞起效时间、平面固定时间、平面消退时间、运动阻滞起效时间、运动阻滞恢复时间。结果麻醉1组的平面消退时间、运动阻滞恢复时间显著短于麻醉2组和麻醉3组,而运动阻滞起效时间显著长于麻醉2组和麻醉3组;麻醉2组的平面消退时间(74.66±7.13)min及运动阻滞恢复时间(82.49±8.52)min显著短于麻醉3组的(94.37±9.25)、(109.63±10.57)min,而运动阻滞起效时间(9.49±0.93)min长于麻醉3组的(7.16±0.77)min,差异具有统计学意义(P<0.05)。三组感觉阻滞起效时间和平面固定时间比较差异无统计学意义(P>0.05)。结论 3 ml 0.25%浓度的罗哌卡因麻醉时虽然运动阻滞起效时间长,但其平面消退时间及运动阻滞恢复时间短,且平面固定时间相对较高浓度小剂量罗哌卡因麻醉无明显区别,该麻醉方式更加符合老年人生理情况,值得应用与推广。
Objective To investigate the efficacy of low dose Ropivacaine with different concentrations in elderly patients undergoing knee and hip joint replacement. Methods A total of 120 patients with artificial knee and hip joint replacement were divided into anesthesia group 1, anesthesia group 2 and anesthesia group 3, 40 cases in each group. Anesthesia group 1, anesthesia group 2 and anesthesia group 3 were given 3 ml 0.15%, 0.25% and 0.50% concentration Ropivacaine puncture anesthesia respectively. The onset time of sensory block, planar fixation time, planar regression time, onset time of motor block, recovery time of motor block in the three groups were recorded and compared. Results The planar regression time and recovery time of motor block in the anesthesia group 1 were significantly shorter than those in the anesthesia group 2 and anesthesia group 3, the onset time of motor block was significantly longer than those in the anesthesia group 2 and anesthesia group 3, at the same time, the planar regression time and recovery time of motor block in the anesthesia group 2 were（74.66±7.13） min and（82.49±8.52） min repectively, which were significantly shorter than（94.37±9.25） min and（109.63±10.57） min in the anesthesia group 3, the onset time of motor block was（9.49±0.93） min, which was significantly longer than（7.16±0.77） min in the anesthesia group 3, the differences were statistically significant in the planar regression time, recovery time of motor block and the onset time of motor block among the three groups（P0.05）. There were no significant differences in the onset time of sensory block and planar fixation time among the three groups（P0.05）. Conclusion Although 3 ml 0.25% concentration Ropivacaine anesthesia has a longer onset time of motor block, but its planar regression time and recovery time of motor block are short, there is no significant difference in the plane fixation time on anesthesia with relatively high concentration of low dose Ropivacaine. This anesthetic method is more consistent with the physiology condition of the elderly people and worthy of application and promotion.
