[Intraoperative fluid infusion and blood transfusion in patients of esophageal cancer].

While patients with esophageal cancer are operated, a large quantity of non-functional extracelluler fluid (ECF) are appeared. Mediastinum, intestines, visceral vessels, wound of thoracotomy and laparotomy, etc, become so called "third space", then much water, Na are shifted and restored there. Moreover, plenty of water are evaporated from operated fields and lymph issues are active. A long time ago, intraoperative fluid infusion was little, but recently more fluid (Hartmann solution) are infused (8 approximately 10/ml/kg/hr). Intraoperative blood transfusion is often done because blood tends to lose. But it sometimes had serious side effects, example for GVHD (graft-versus-host disease), infections. In order to prevent from thease, autotransfusion and irradiation to transfused blood are recommended.
