Pleth Variability Index and Fluid Management During Surgery

Is Pleth Variability Index Able to Guide Fluid Management During Surgery?

Pleth Variability Index (PVI) seems to be an ideal parameter to guide fluid management: dynamic parameter and non-invasive. PVI could guide fluid management during surgery and optimization of the plethysmographic-derived parameter could improve hemodynamics of the patients.

Inclusion Criteria:

• Major abdominal surgery

Exclusion Criteria:

• Refusal or inability to understand the protocol
• Arrythmia
• <18 years
• Contraindication to normal mechanical ventilation
