| Abstract | 「要旨」開胸術における連続心拍出量測定装置による心拍出量値(CCO)は, 体位変換及び開胸に伴う手術操作が加わるため測定値に誤差が生じると考えられる. 我々は, 体位変換時と開胸前後・分離換気時の連続心拍出量測定装置によるCCOと冷却水注入法による心拍出量値(BCO)の測定を行い比較検討した. CCOとBCOの相関は開胸時に最も良好(r=0.92 p<0.001)で開胸時には不良(r=0.36 p=0.30)であった. 開胸術におけるCCOのモニタリングは手術操作および時間的差異による変動が大きく循環動態の評価には注意が必要であると思われた. |

| Abstract | Continuos thermodilution cardiac output measurement (CCO) has been widely used in cardiac surgery and the intensive care unit. There have been few studies on the accuracy and reliability of CCO during thoracic surgery. We compared CCO and bolus thermodilution cardiac output measurements (BCO) in thoracic surgery, using a linear regression analysis and the limits of agreement. Twenty-two patients requiring pulmonary lobectomy were anesthetized by combined propofol-fentanyl with epidural anesthesia. The correlation between CCO and BCO was highest (r=0.92, y±0.99x +0.62, p<0.001: independent lung, r=0.92, y=0.88x + 0.21, p<0.01: dependent lung), with high accuracy at the end of surgery. The correlation between CCO and BCO was lowest (r=0.36, y=0.44x + 2.33, p=0.30: independent lung, r=0.71, y=1.2x - 0.37, p=0.02: dependent lung), with low accuracy during thoracotomy. These data showed that CCO was affected by several factors, such as intraoperative manipulation of the lung and time that elapsed from cardiac output calculation during thoracptomy. It was concluded that the evaluation of hemodynamics with CCO is stll limited in thoracic surgery and that further refinement is needed in the design of CCO device. |
