1、舒芬太尼在心肌缺血再灌注損傷中的心肌保護作用楊凱1藍竹2鐘敏2廖敏2肖建斌2(通訊作者)(1廣州中醫(yī)藥大學第二臨床醫(yī)學院在讀研究生廣東廣州510000)(2廣州中醫(yī)藥大學第二附屬醫(yī)院麻醉科廣東廣州510000)【摘要】目的:探討舒芬太尼在心肌缺血再灌注損傷中心肌保護效應的作用。方法:24只健康雄性SD大鼠(200?250g)隨機分為4組,假手術(Sham)組,缺血再灌注(I/R)組,I/R+舒芬太尼組,Sham+舒芬太尼組。Sham組:只開胸但不結扎冠狀動脈,靜脈注射等量生理鹽水;I/R組:開胸造MIRI模型(缺血30min,再灌注120min)注射等量生理鹽水;I/R+S
2、組:缺血前泵注舒芬太尼lμg/kg,栗注5min,停止5min,重復3次,總量共3μg/kg的預處理方式;Sham+S組:不結扎冠狀動脈,相同方式注射舒芬太尼3μg/kg;再灌注120min后于腹主動脈抽取血液2ml,然后取心肌標木。血液標木檢測CK-MB、LDH心肌酶。結果:四組雄性大鼠HR差異無統(tǒng)計學意義,I/R組與I/R+S組相比心肌酶(CK-MB值)從2538.9U/L下降到1577.6U/L,差異有統(tǒng)計學意義(P<0.05)。結論:舒芬太尼在心肌缺血再灌注損傷中只有心肌保護作用。【關鍵詞】心肌缺血再灌注損傷;心肌預處理;舒芬太尼【中圖分類號
