Goal Directed Therapy Versus Standard Care in Lung Resection Surgery (GDT-thorax Study).

Goal Directed Therapy Versus Standard Care in Lung Resection Surgery, a Randomized, Controlled Trial (GDT-thorax Study).

The primary aim of this study is to quantify and compare the hemodynamic control of cardiac index in patients who receive either goal-directed therapy or standard hemodynamic management in lung resection surgery

The investigators hypothesize that the percentage of the intraoperative time in which the cardiac index is equal or superior to 2.2 l/min/m2 is higher in goal directed therapy

Inclusion Criteria:

• Adults patients ( 18 years old)
• Written informed consent
• Elective lung resection surgery (open or thoracoscopic lung lobectomy)

Exclusion Criteria:

• Severe obesity
• Moderate to severe aortic insufficiency
• Renal failure requiring hemodialysis
• Left ventricle ejection fraction less than 35 %
• Urgent surgery
