Abstract | 麻酔患者10名を対象として手術侵襲のない条件下でNTGの持続静脈内投与(1μg/kg・min)による循環動態の変化を調べ, NTGの循環動態, 血小板機能への作用がプロスタグランディン合成阻害剤であるインドメサシンの投与により影響を受けるか否かを検討した. 循環動態の変化は, 投与開始後5分で著明で, 15分以降の循環動態の変動は緩除であった. この変化はNTGの血清濃度の推移と平行していた. NTG投与による循環動態の変化はインドメサシン投与群, インドメサシン非投与群でほぼ同様であった. またNTG投与による血小板機能にも抑制効果を認めなかった. このことから, NTGの末梢血管拡張作用にプロスタサイクリンが関与している可能性は少ないことが結論された. |

Abstract | The hemodynamic effects of intravenous infusion of Nitroglycerin(NTG, 1μg/ml・min) were investigated in ten patients under condition of no surgical stimulation, and the hypothesis that NTG exerts its effects through stimulation of prostaglandin synthesis was tested. The marked change of hemodynamic parameters was observed at five minutes after the beginning of the infusion. After 15 minutes there were no significant hemodynamic changes. These hemodynamic changes seemed to related to the plasma NTG levels. Pretreatment with indomethacin(50mg) failed to inhibit the hemodynamic changes by NTG infusion. Platelet aggregation and adhesion were not affected by NTG infusion. These results suggest that NTG does not induce its effects in vivo by stimulation of prostaglandin synthesis. |
