Abstract「要約」ラット摘出心における虚血再灌流モデルで, エピネフリン併用時のハロタンの再灌流不整脈に及ぼす影響について検討した. 実験は, Langendorff法による冠灌流を行い, 左冠状動脈前下行枝を6分間結紮閉塞させ, その後, 結紮の解除によって再灌流を行った. 再灌流時に発生する心室性の再灌流不整脈については, エピネフリン単独投与時, エピネフリン・ハロタン併用は各々について, 心室細動を指標としてその発現頻度, 持続時間について比較検討した. エピネフリン単独投与群においては, 10-5mol/lで最も心室細動の発現頻度が多かった. ハロタンは, エピネフリン併用投与下の再灌流時において, 10-6, 10-5mol/lの濃度でVFの発現頻度, 持続時間に抑制効果を示した. ハロタンは, エピネフリン投与下の再灌流不整脈に対して抑制効果を持つことが示された.

AbstractUsing the isolated perfused rat heart, we have investigated the influence of halothane on the reperfusion-induced arrhythmias when epinephrinne is given simultaneously. Isolated rat hearts (n=108) were subjected to regional ischemia (occlusion of left anterior descending coronary artery for 6 minutes) and reperfusion (3 minutes). The incidence and the duration of ventricular fibrillation (VF) which arrised at the reperfusion period were studied as parameters of reperfusion-induced arrhythmias. When epinephrine was administered individually, the incidence of VF and the duration of VF increased in the concentration of 10-7 to 10-5 mol/l. But the concomitant use of 2MAC of halothane with epinephrine caused the reduction of both the incidence and the duration of reperfusion-induced VF compared with those when the same doses of epinephrine were given independently. The results of the present study indicate that epinephrine enhances the reperfusioninduced arrhythmias, but that halothane can inhibit reperfusion-induced arrythmias, but that halothane can inhibit reperfusion-induced arrhythmias even in the presence of epinephrine .
