| Abstract | 「要旨」手術時の麻酔管理における心拍出量及び関連する循環諸量を得ることは有用である. 今回は超音波ドプラ法により心拍出量のモニタリングを行い, エンフルレン/笑気麻酔下における胸部硬膜外麻酔の循環動態に及ぼす変化を検討した. エンフルレン/笑気麻酔に硬膜外麻酔を加えると血圧は低下したが, 心拍出量は維持されていた. 経食道的超音波ドプラ法による測定では心拍出量を非侵襲的, 連続的に測定することが可能であり, 臨床的に有用なモニタリング手段であると結論を得た. |

| Abstract | Esophageal Doppler ultrasonography is a relatively noninvasive method of cardiac output determination, and it significantly correlates with thermodilution cardiac output. In this study, we evaluated the hemodynamic effects of thoracic epidural anesthesia with epinephrine-containing lidocaine under enflurane/nitrous oxide anesthesia in 9 patients (mean age：51.6 year old) scheduled for elective surgery with an available esophageal Doppler cardiac output monitoring device L-3000(R), (Lawrence Medical Systems, U.S.A.) Thoracic epidural anesthesia produced a decrease in blood pressure, a slight increase in cardiac index and significant decrease in systemic vascular resitance. These results are accor dance with preitous reports. Our results indicate that esoqhageal Doppler method is an usefu1 modality to evaluate hemodynamic effects of throacic epidurel anesthesia and that this can provide us more imformation on hemodynamic state of patients in anesthesia than standard monitoring of blood pressure and ECG alone. In summary, we conclude that esophageal Doppler ultrasonography is a nonivasive method that allows continuous monitoring of cardiac output during anesthesia and it may improve patient's care in anesthesia. |
