七氟醚预处理对体外循环心内直视手术患者围术期
心肌保护和全身抗炎作用的开题报告
【摘要】
目的:探讨七氟醚预处理对体外循环心内直视手术患者围术期心肌
保护和全身抗炎作用的影响。
方法:随机选择100例体外循环心内直视手术患者,分为七氟醚组
和对照组。对照组使用常规麻醉方法,七氟醚组在常规麻醉前15分钟使
用3%七氟醚维持5分钟,停止3分钟,再维持5分钟,共进行3次。
比较两组围术期心肌酶谱的变化和全身炎症因子的水平。
结果:七氟醚组围手术CK-MB、cTnI水平明显低于对照组;术后
12小时,七氟醚组hs-CRP、IL-6、TNF-α水平低于对照组。七氟醚组术
后并发症发生率低于对照组。
结论:七氟醚预处理可显著降低体外循环心内直视手术患者围术
心肌损伤和全身炎症反应,具有潜在的心肌保护和全身抗炎作用。
