七氟烷与丙泊酚麻醉对老年高血压患者围手术期心肌损伤的影响比较
Comparison of the influence of sevoflurane and propofol on cardiac damage of surgery patients with hypertension
目的 比较七氟烷与丙泊酚麻醉对老年高血压患者围手术期心肌损伤的影响.方法 将45例老年高血压非心脏手术患者按照麻醉方式分为七氟烷组22例与丙泊酚组23例,分别观察其手术前后心电图ST段变化以及肌酸激酶同工酶、肌红蛋白、肌钙蛋白等心肌坏死标志物变化情况.结果 麻醉诱导后24h,所有患者均有一定程度的心肌损伤;与七氟烷组相比,丙泊酚组麻醉诱导后24h肌酸激酶同工酶、肌红蛋白及肌钙蛋白水平显著升高(t=2.771、0.681、0.557,均P<0.05),心电图ST段显著压低[分别为(-1.96±0.06)mV、(-1.45±0.04)mV](P <0.05).结论 老年高血压患者围手术期伴有心肌损伤,与丙泊酚相比,吸入麻醉剂七氟烷对心肌损伤影响较轻.
更多Objective To compare the effect of sevoflurane and propofol in elderly surgery patients towards cardiac damage.Methods 45 elderly patients with hypertension were divided into Sevoflurane group and Propofol group,which were observed changes of their ECG ST-segment,Mb,CK-MB,cTnI.Results 24 hours after induction of anesthesia,cardiac damage could be observed;Compared with Sevoflurane group,levels of CK-MB,Mb and cTnI increased significantly 24 hours after induction of anesthesia(t =2.771,0.681,0.557,all P < 0.05),ST-segment significantly depressed at the same time[(-1.96±0.06)mV,(-1.45±0.04)mV](P <0.05).Conclusion Elderly patients with hypertension show cardiac damage during pevi-operative stage;Compared with propofol,sevoflurane shows lighter damage to cardiac muscle.
