    Abstract:
    We evaluated the right ventricular function in pre- and post-operative esophageal cancer patients who had no complications after surgery by measurement of cardiopulmonary hemodynamics, right ventricular ejection fraction (RVEF) and right ventricular end-diastolic volume index (RVEDVI) using Swan-Ganz catheter and the thermodilution technique. The measurement of RVEF, RVEDVI and other cardiopulmonary hemodynamics were performed from the preoperative day to the 3rd postoperative day. The values of RVEF were stable about 40% from preoperative day to 3rd. RVEDVI was varied at 93.6 +/- 26.3 ml/m2 (preoperative day), 83.6 +/- 15.0 ml/m2 (after surgery), 70.2 +/- 10.6 mg/m2 (morning of the 1st POD), 95.6 +/- 19.4 ml/m2 (evening of the 1st POD), 103.2 +/- 17.9 m/lm2 (morning of the 2nd POD), 1108.3 +/- 14.2 ml/m2 (evening of the 2nd POD) and 112.4 +/- 31.0 ml/m2 (morning of the 3rd POD). The values of RVEDVI on the morning of the 1st POD were statistically lower than those at other times (p < 0.05). The values of RVEDVI were not correlated with mean pulmonary arterial pressure and pulmonary arteriolar resistance which were the afterload of the right ventricle. These data suggest that the right ventricular function of the patients who underwent esophagectomy with no complication does not change and that the changes of RVEDVI are influenced by the preload of the right ventricle.
