Impact of Using an Hemodynamic Monitoring System on Anesthetic Consumption During Abdominal Surgery

Impact of Using an Hemodynamic Monitoring System on Anesthetic Consumption During Abdominal Surgery

In this study investigators will study the association between the use of an hemodynamic monitoring system and the anesthetic consumption in patients following major abdominal surgery. Investigators will randomise patients for a control group and an intervention group. Patients belonging to intervention group will be monitored with a non-invasively continue system (Acumen IQ cuff sensor), while the control group will be monitored with a non-invasive intermittent pressure system. The total amount of mL of Sevoflurane will be registered in both groups and the difference will be considered as the aim of our study
