摘要
目的探讨右美托咪定在上肢手术患者术后连续臂丛神经阻滞镇痛中的应用效果。方法选取2018年5月至2019年12月在本院进行手术治疗的单侧上肢骨折患者62例,随机分为对照组和观察组,每组31例。对照组采用罗哌卡因镇痛,观察组在对照组基础上联合右美托咪定镇痛。两组患者均接受臂丛神经阻滞麻醉术,术毕患者清醒后自控臂丛神经阻滞镇痛。比较两组术后4、8、12、24、48 h时视觉模拟评分量表(VAS)评分,术后24、36和48 h患侧肢体运动时NRS评分,不良反应情况及术后48 h镇痛效果的满意度。结果术后4、8、12、24、48 h,观察组VAS评分均低于对照组(P<0.05)。术后24、36和48 h,观察组患侧肢体运动时NRS评分均低于对照组(P<0.05)。术后,两组不良反应发生率比较差异无统计学意义。观察组满意度高于对照组,差异有统计学意义(P<0.05)。结论右美托咪定联合罗哌卡因在上肢手术后连续臂丛神经阻滞镇痛中效果显著,术后镇痛时间长,患者满意度高。
Objective To investigate the effect of dexmedetomidine in continuous brachial plexus block analgesia after upper limb surgery.Methods 62 patients with unilateral upper limb fractures who underwent surgical treatment in our hospital from May 2018 to December 2019 were randomly divided into control group and observation group,with 31 cases in each group.The control group was treated with ropivacaine for analgesia,and the observation group was combined with dexmedetomidine for analgesia on the basis of the control group.Both groups of patients received brachial plexus block anesthesia.After the operation,the patients were awake and self-controlled brachial plexus block analgesia.The visual analogue scale(VAS)scores at 4,8,12,24,and 48 hours after the operation,the NRS scores during the movement of the affected limb at 24,36,and 48 hours after the operation,the adverse reactions and satisfaction with analgesic effect the 48 hours after the operation were compared between the two groups.Results The VAS scores of the observation group were lower than those of the control group at 4,8,12,24,and 48 hours after operation(P<0.05).The NRS scores of the affected limbs in the observation group were lower than those in the control group at 24,36,and 48 hours after operation(P<0.05).There was no statistically significant difference in the incidence of adverse reactions between the two groups.The satisfaction degree of the observation group was higher than that of the control group,the difference was statistically significant(P<0.05).Conclusion Dexmedetomidine combined with ropivacaine has significant effect on continuous brachial plexus block analgesia after upper limb surgery.The postoperative analgesia time is long and patient satisfaction is high.
