| Abstract | 「I. 緒言」従来左心系に比較し右心系の血行動態の評価は, その複雑な幾何学的形態より心血管造影法や超音波法では困難な面もあったが, この点RIによる方法は有利である. Kr-81mは短半減期13秒で, かつ肺胞より気道系に99%以上排出されるため, 左心系にはほとんど到達せず, 右心系の動態を観察するのに適当と思われる. 最近優れた81Rb-81mKr generatorが供給可能となり反復投与が可能となった. われわれはかかるKr-81mの性質を利用しKr-81mの急速また持続注入によって右心機能評価を臨床的に検討してきたので, その術式を含め報告する. 今回は, 特にKr-81mとnuclear cardiac single probe(single probe)を用いbedsideで右室駆出率(right ventricular ejection fraction:RVEF)を測定する方法の妥当性を検討した. |

| Abstract | [Summary]We develop the new method of monitoring right ventricular (RV) ejection fraction by single probe and Kr-81m. Kr-81m is eliminated almost entirely by the lung without reaching the left ventricle. This makes possible monitoring RV ejection fraction without left heart activity and with low background activity. Kr-81m was injected serially as a bolus (2-3 ml) of 5 % glucose solution eluting a rubidium-krypton generator. RV ejection fraction was calculated from the first pass time-activity curve after correcting for background. RV ejection fraction by omniscope showed a good agreement with camera-RV ejection fraction And simultaneous display of RV time-activity curve with ECG and phonocardiogram was done. The effect of sublingual nitroglycerin on RV ejection fraction by omniscope was also monitored. This new method is potentially useful in the coronary care unit and intensive care unit, where a rapid estimation of RV ejection fraction is needed. |
