切口局部浸润镇痛在半髋关节置换术后早期康复训练中的效果

目的 评价右美托咪定联合罗哌卡因切口局部浸润镇痛在半髋关节置换术后早期康复训练中的效果.方法 2019年1月至2020年12月老年股骨颈骨折患者60例,均接受半髋置换术,随机分为观察组和对照组.观察组采用罗哌卡因联合右美托咪定切口局部浸润镇痛,对照组不作特殊处理.视觉模拟评分法(VAS)评价术后6 h(T_(1))、12 h(T_(2))、24 h(T_(3))、48 h(T4)早期康复训练时的疼痛程度,心电监护并计算心率收缩压乘积(RPP).结果 T_(1)、T_(2)、T_(3)时观察组VAS评分和RPP与对照组比较明显降低,差异有统计学意义(P<0.05).T4时两组VAS评分及RPP差异无统计学意义(P>0.05).结论 右美托咪定联合罗哌卡因切口局部浸润镇痛,可减轻老年患者半髋置换术后24 h早期康复训练时疼痛程度,降低心肌耗氧量.

Objective To evaluate the effect of local infiltration analgesia through dexmedetomidine combined with ropivacaine incision in early rehabilitation training after hemiarthroplasty.Methods Sixty elderly patients with femoral neck fracture were selected from the department of Orthopedics of our hospital from January 2019 to December 2020.All paticnts received hemi hip replacement,and were randomly divided into study group and control group.In study group,ropivacaine combined with dexmedetomidine was injected as local anesthetic.The control group was not treated specially.Visual analogue scale(VAS)was used to evaluate the pain degree at 6 h(T_(1)),12 h(T_(2)),24 h(T_(3))and 48 h(T4)of early rehabilitation training after surgery.ECG monitoring was performed and heart rate pressure product(RPP)was calculated.Results VAS score and RPP at T_(1),T_(2) and T_(3) in the study group was all significantly lower than those in the control group,with statistical significance(P<0.05).There were no significant differences in VAS score and RPP between the two groups at T(P>0.05).Conclusion Dexmedetomidine combined with ropivacaine incision local infiltration analgesia can reduce the pain degree and myocardial oxygen consumption in the 24 h early rehabilitation training after hemiarthroplasty in elderly patients.
