| Abstract | 「要旨」小児における湿気管内ドップラー法による心拍出量の測定の精度を調べる目的で, 小児手術患者15例において心拍出量を経気管内ドップラー法(TTD), 心エコー法(EC)の両法で同時に測定した. 両法の間の相関係数は0.93で有意の相関関係が成り立ち(p<0.001), 回帰直線はTTD=0.83EC+0.12であった. また, 両法の間の誤差範囲は-32%から28%であった. 小児における経気管内ドップラー法による心拍出量の測定は, その限界と技術に習熟すれば臨床使用上有用であると思われる. |

| Abstract | In order to evaluate the accuracy of cardiac output (CO) measured by transtracheal doppler (TTD) in pediatric patients, intraoperative measurement of CO by TTD was compared with that by echocardiograph (EC). CO was measured simultaneously with both methods in 15 pediatric patients under general anesthesia. The correlation coefficient of TTFCO to ECCO was 0.93 (p<0.001) and linear regression yielded following equation TTDCO=0.83ECCO+0.12. The average of the difference between log-transformed values made with the two methods was -0.05, with the standard deviation 0.08. The limitation of agreement was -0.21 to 0.11. The antilog-transformed values of the limitation of agreement was 0.62 to 1.28. These data indicate that the relationship between values measured by two methods is strong and the erro of TTDCO was -38% to 28% compared with ECCO. We conclude that TTD is a useful monitoring during pediatric patients under general anesthesia. |
