不同药物浓度的罗哌卡因神经阻滞效果观察

Observation on different effects of different drug concentrations of ropivacaine in nerve block

目的:探究不同药物浓度的罗哌卡因神经阻滞产生的不同效果.方法:2017年5月-2019年5月收治上肢手术患者140例,随机分为两组,各70例.观察组给予浓度为0.5%罗哌卡因治疗;对照组给予浓度为0.25%罗哌卡因治疗.比较两组神经阻滞时间、术后止痛时间及阻滞成功率.结果:两组神经阻滞时间比较,差异无统计学意义(P>0.05);观察组术后止痛时间长于对照组,神经阻滞成功率高于对照组,差异均有统计学意义(P<0.05).结论:不同浓度罗哌卡因神经阻滞能够获得不同治疗效果,罗哌卡因在安全范围内浓度越高越可以获得良好效果.

Objective:To explore the different effects of different concentrations of ropivacaine in nerve block.Methods:From May 2017 to May 2019,140 patients with upper limb surgery were enrolled,they were randomly divided into two groups with 70 cases in each group.The observation group was treated with 0.5%ropivacaine and the control group was treated with 0.25%ropivacaine.The time of nerve block,the time of postoperative pain relief and the success rate of block were compared.Results:The nerve block time between the two groups was compared,the difference was not statistically significant(P>0.05);The time of postoperative pain relief in the observation group was longer than in the control group,the success rate of nerve block was higher than in the control group,the differences were statistically significant(P<0.05).Conclusion:Different concentrations of ropivacaine in nerve block can achieve different therapeutic effects.The higher the concentration of ropivacaine in the safe range,the better the effect can be obtained.
