How should we decide the optimum intraoperative fluid and colloid usage in pulmonary resection?

Lung cancer is the leading cause of cancer death throughout the world and pulmonary resection remains a major surgical procedure for the cure of localized non-small cell lung cancer. Respiratory complications are still the major cause of mortality and morbidity after lung resection. Pneumonia and acute respiratory distress syndrome (ARDS) are responsible for the great part of respiratory-related deaths after lung resection (1).
