摘要
目的 探讨右美托咪定复合罗哌卡因收肌管阻滞在全膝关节置换术后镇痛效果。方法 选取该院2018年1月—2020年1月收治的60例全膝关节置换术患者作为研究对象,按照简单随机化法分为对照组(n=30,予以罗哌卡因)和观察组(n=30,在对照组的基础上予以右美托咪定),观察两组患者镇痛效果和镇痛药追加次数、血流动力学及不良反应的发生情况。结果 观察组患者爆发痛镇痛后VAS评分(2.64±0.82)分低于对照组、镇痛药追加次数(1.00±0.12)次少于对照组,差异有统计学意义(t=7.333、4.782,P<0.05);治疗后,观察组血流动力学(每搏输出量、心排血量、心脏指数)水平高于对照组,差异有统计学意义(P<0.05);观察组不良反应发生率低于对照组,但差异无统计学意义(P>0.05)。结论 全膝关节置换术患者应用右美托咪定复合罗哌卡因收肌管阻滞,镇痛效果较好,药物追加次数少、可维持血流动力学稳定,不良反应发生较少。
Objective To investigate the analgesic effect of dexmedetomidine combined with ropivacaine adductor canal block af-ter total knee arthroplasty. Methods 60 patients with total knee arthroplasty who were treated in the hospital from January 2018to January 2020 were selected as the research subjects and divided into the control group(n=30, given ropivacaine) and the observation group(n=30, dexmedetomidine was given on the basis of the control group), the analgesic effect, the number of additional analgesics, hemodynamics and the occurrence of adverse reactions were observed in the two groups. Results The VAS score(2.64±0.82)points of the patients in the observation group was lower than the control group, and the number of additional analgesics(1.00±0.12)points was less than that of the control group, the difference was statistically significant(t=7.333, 4.782,P<0.05);after treatment, the hemodynamic(stroke volume, cardiac output, cardiac index) level of the observation group was higher than that of the control group, the difference was statistically significant(P<0.05);the incidence of adverse reactions in the observation group was lower than that of the control group, but the difference was not statistically significant(P>0.05). Conclusion Dexmedetomidine combined with ropivacaine for adductor canal block in patients undergoing total knee arthroplasty has better analgesic effect, fewer drug additions, stable hemodynamics, and fewer adverse reactions.
