Optimal fluid therapy for thoracic surgery
Intraoperative fluid optimization is important for improving the prognosis after thoracic surgery (1,2). Several prior studies have demonstrated that excessive intravenous fluid intake may be linked to an increased risk of pulmonary complications following these operations (3-5). Therefore, a restrictive fluid therapy strategy that aims to achieve a negative fluid balance is currently the preferred technique for achieving a good prognosis after thoracic surgery (2,6). Additionally, and despite known adverse effects such as renal injury and coagulation impairment, colloids including hydroxyethyl starch are often used to reduce the total intravenous fluids administered during thoracic operations (6,7).
