For expansion of the extravascular space, secretion of antidiuretic hormone and increment of vascular permeability, a large quantity of non-functional extracellular fluid is accumulated in an extravascular space from all over the operation. Extracellular fluid returns from an extravascular space to blood vessels in refilling stage, and decrement of a pulmonary vascular bed after pneumoresection make it easy to cause pulmonary edema and tachyarrhythmia. Therefore volume of postoperative infusion is apt to be limited after pneumoresection. However, the fluid management that extremely imbalanced in dry side increases the risk of arrhythmia, myocardial infarction and cerebral infarction. It is important to perform reasonable fluid therapy without excess and deficiency postoperatively while observing amount of urine, specific gravity of urine, heart rate, blood pressure, volume of chest drainage and central venous pressure. We have few opportunity to consider about nutritional management after pneumoresection so that ingestion is started for an early postoperative period. But, the grave case that ingestion cannot start for an early postoperative period should start total parenteral nutrition or enteral feeding. In that case, the enteral feeding which is more physiological than intravenous nutrition is recommended.
