| Abstract | 「要旨」経食道心エコー法を用いて心臓手術中の冠血流速評価を試みた. 弁置換等の非冠動脈手術症例7人(以下非冠動脈群)と冠動脈バイパスグラフト手術症例9人(以下冠動脈群)に分類して, イソフルラン濃度を0, 1, 2%と変化させたときの左冠動脈主幹部LMTの冠血流速を測定した. 血行動態値は, イソフルラン0%のときに比べて, 1%および2%のときの両群の血圧および2%のときの冠動脈群の全身血管抵抗が有意に低下した. 冠血流速は, イソフルラン濃度上昇に伴い, 非冠動脈群で上昇する傾向にあった. 群内比較では冠動脈群の拡張期で0%と2%値(0.76±0.20 VS 1.18±0.29 m・sec-1)のみ有意差があった. 群間比較では有意差はなかったがイソフルラン各濃度において冠動脈群は非冠動脈群と比べ拡張期は速く, 収縮期は遅い傾向にあった. |

| Abstract | Coronary artery (left main trunc) blood flow velocity (CBFV) changes were measured with transesophageal echocardiography in response to inhaled isoflurane at the concentrations of 0%, 1% and 2%, in 7 non-coronary cardiac surgery patients (non coronary group) and in 9 coronary bypass graft surgery patients (coronary goup). Anesthesia was maintained with high dose fentanyl, diazepam and pancuronium, and isoflurane was additionally inhaled during CBFV measurements. Systemic blood pressure decreased significantly in both groups and systemic vascular resistance index decreased significantly at 2 % isoflurane inhalation in the coronary group. CBFV changes in the non coronary group in response to inhaled isoflurane were not significant. Both systolic and diastolic CBFV increased in the non coronary group as the isoflurane concentration increased, however, no significance was observed. In coronary group, 2 % isoflurane inhalation significantly increased diastolic CBFV compared to the non inhaled patients (0.76±0.20 vs 1.18±0.29 m/sec). Although no significanct difference in CBFV was seen between both groups, CBFV in the coronary group was faster at diastolic state and slower at systolic state than those of non coronary group.
