Hemodynamic (MAP) Stability

This study will investigate the impact of using an automated fluid management system on intraoperative fluid therapy in patients undergoing colorectal surgery. The aim is to evaluate whether automated guidance can optimize hemodynamic stability and reduce the incidence of arterial hypotension,

The goal of this clinical trial is to learn if using artificial intelligence to guide intravenous fluid therapy during major cancer surgery can help keep blood pressure more stable compared with usual care in adult patients undergoing major cancer surgery. The main questions it aims to answer are: * Does artificial intelligence-guided fluid therapy reduce hypotensive events during surgery? * Does this approach improve recovery and reduce complications after major cancer surgery? Researchers will compare artificial intelligence-guided fluid therapy with standard fluid management to see if the artificial intelligence-guided approach provides better support during surgery. Participants will: * Undergo major cancer surgery under general anesthesia * Receive either artificial intelligence-guided fluid management or standard fluid management during surgery * Be monitored during and after surgery as part of routine clinical care * Be followed after surgery to assess recovery and possible complications

intraoperative hemodynamic optimization will be based on the percentage of variation of the parameters
