So sánh tác dụng ức chế vận động, cảm giác và ảnh hưởng trên tuần hoàn của ropivacain 0,1% và bupivacain 0,1% trong giảm đau ngoài màng cứng sau phẫu thuật khớp háng trên người cao tuổi

Abstract

Objective: To compare the effects on mobilization, sensory and cardiovascular in patient controlled epidural analgesia by 0.1% ropivacaine or 0.1% bupivacaine after hip surgery in the elderly. Subject and method: A comparative randomized clinical intervention study. 104 patients ≥ 60 years of age, indicated for hip surgery, had no contraindications for epidural anesthesia. 52 patients in group R used ropivacaine 0.1% and 52 patients group B used bupivacaine 0.1% and both group added fentanyl 1mcg/ml. Result: Both groups had a good analgesic effect, VAS scores at rest or exercise were lower than 4. The Bromage score M₂ of group B was 13.5% higher than that of group R (p<0.05). There was no difference of the mean blood pressure or heart rate between both groups (p>0.05). Conclusion: The effects of patient controlled epidural analgesia with bupivacaine 0.1% or ropivacaine 0.1% were good for elderly after hip surgery. The Bromage score of group B higher than group R. There was no difference of the mean blood pressure or heart rate between both groups.
