分析不同浓度罗哌卡因用于超声引导下肌间沟臂丛神经阻滞的麻醉效果

Analysis of the anesthesia effects of different concentrations of ropivacaine for ultrasound-guided intermuscular groove brachial plexus block

目的分析不同浓度罗哌卡因用于超声引导下肌间沟臂丛神经阻滞的麻醉效果。方法60例行上肢手术患者,以乱数表法分为参照组和研究组,各30例。研究组给予中等浓度罗哌卡因麻醉,参照组给予低等浓度罗哌卡因麻醉。比较两组术后苏醒时间、镇痛维持时间、麻醉起效时间。结果研究组术后苏醒时间(8.63±1.34)h、镇痛维持时间(7.47±1.05)h长于参照组的(6.86±2.18)、(5.57±1.08)h,麻醉起效时间(0.45±0.16)h短于参照组的(0.77±0.12)h,差异有统计学意义(P<0.05)。结论行中等浓度罗哌卡因麻醉取得了更为理想手术麻醉效果,不同浓度罗哌卡因麻醉在临床上均有一定的价值,但是在一定范围内的浓度越高,患者麻醉阻滞时间越长,麻醉的起效时间越短,患者镇痛维持时间更长,有更好的麻醉效果。

Objective To analyze the anesthesia effects of different concentrations of ropivacaine for ultrasound-guided intermuscular groove brachial plexus block.Methods A total of 60 patients undergoing upper limb surgery were divided into reference group and research group by random numerical table,with 30 cases in each group.The research group was anesthetized with medium concentration of ropivacaine,and the reference group was anesthetized with low concentration of ropivacaine anesthesia.The postoperative recovery time,analgesia maintenance time,and anesthesia onset time were compared between the two groups.Results The postoperative recovery time(8.63±1.34)h and analgesia maintenance time(7.47±1.05)h of the research group were longer than(6.86±2.18)and(5.57±1.08)h of the reference group,and the anesthesia onset time(0.45±0.16)h was shorter than(0.77±0.12)h of the reference group.All the differences were statistically significant(P<0.05).Conclusion Medium-concentration of ropivacaine has achieved a more ideal surgical anesthesia effect.Different concentrations of ropivacaine anesthesia are clinically valuable,but the higher the concentration in a certain range,the longer the patient’s anesthetic block time,the shorter the onset of anesthesia,the longer the patient’s maintenance time,and the better the anesthetic effect.
