摘要
目的探讨基于超声、神经刺激仪联合引导下右美托咪定、甲磺酸罗哌卡因联合麻醉方案进行臂丛神经阻滞的效果。方法方便选取2019年1月—2020年12月于该院接受手术治疗的患者120例,根据抛硬币结果划分观察组(正面,60例)与对照组(背面,60例),对照组用药单纯为甲磺酸罗哌卡因,观察组用药为右美托咪定、甲磺酸罗哌卡因复合,比较两组患者麻醉情况,监测患者手术期间(入室时间-T0、麻醉后10 min-T1、开始手术-T2、手术30 min-T3、手术结束-T4)血压、心率指标变化,统计不良反应总发生率。结果观察组患者感觉、运动阻滞起效时间均短于对照组,感觉、运动、镇痛维持时间长于对照组,差异有统计学意义(P<0.05)。两组患者T0、T3、T4时间血压、心率指标对比差异无统计学意义(P>0.05);观察组患者T1、T2时间平均动脉压(74.25±4.29)mmHg、(75.15±3.89)mmHg、心率(72.31±4.46)次/min、(75.71±4.22)次/min指标明显低于对照组,差异有统计学意义(t=6.136、7.917、7.045、4.364,P<0.05)。两组患者不良反应总发生率比较,差异无统计学意义(P>0.05)。结论超声联合神经刺激仪引导臂丛神经阻滞麻醉可选用右美托咪定、甲磺酸罗哌卡因复合用药方案,具有良好麻醉及镇痛效果,提倡推广。
Objective To investigate the effect of brachial plexus block based on ultrasound,nerve stimulator combined with guidance of dexmedetomidine,ropivacaine mesylate combined with anesthesia.Methods From January 2019 to December 2020,120 patients who received surgical treatment in the hospital was conveniently selected as research target.According to the results of coin tossing,the observation group(heads,60 cases)and the control group(tails,60 cases)were divided.The control group was given ropivacaine mesylate alone,while the observation group was given the combination of dexmedetomidine and ropivacaine mesylate.The anesthesia conditions of the two groups of patients were compared.The changes of blood pressure and heart rate indicators were monitored during the operation(T0-10 minutes after anesthesia,T1-T2-30 minutes,T3 and T4-after the operation),and the total incidence of adverse reactions was counted.Results The onset time of sensory and motor block in the observation group was shorter than that in the control group,and the maintenance time of sensory,motor and analgesia was longer than that in the control group,the difference was statistically significant(P<0.05).There was no statistically significant difference in blood pressure and heart rate at T0,T3,and T4 between the two groups(P>0.05).The mean arterial pressure(74.25±4.29)mmHg,(75.15±3.89)mmHg,heart rate(72.31±4.46)times/min and(75.71±4.22)times/min in the observation group were significantly lower than those in the control group,the difference was statistically significant(t=6.136,7.917,7.045,4.364,P<0.05).In addition,there was no statistically significant difference in the total incidence of adverse reactions between the two groups(P>0.05).Conclusion Ultrasound combined with nerve stimulator-guided brachial plexus block anesthesia can choose the combined drug regimen of dexmedetomidine and ropivacaine mesylate.It has good anesthesia and analgesic effects and is recommended for promotion.
