Summary

Intraoperative hemodynamic management is important, since even mild variations in circulatory volume can be extremely damaging for patients.

Minimally invasive hemodynamic monitoring are not always available or cost-effective, therefore management of fluids is challenging for anesthesiologists.

This study aims to assess if, after performance of a lung recruitment maneuver (LRM), standard parameter's variation differs between hypovolemic and normovolemic patients.

Patients' volemic state will be assessed with the Vigileo system. Standard monitoring values (heart rate, invasive blood pressure and saturation) will be registered before and after LRMs.

A fluid challenge will be performed and the above mentioned parameters will be recorded again, after a second LRM.

The study is a prospective observational study.

Conditions

  • Hypovolemia

Interventions

PROCEDURE

Vigileo monitoring during lung recruitment maneuver

Standard monitoring parameters, invasive blood pressure and hemodynamic values (SVV and CO, through Vigileo device) will be monitored. With the patient in a supine position and as SVV reaches a value of 12-15%, a LRM is performed, consisting in the application of 30 cm H2O continuous positive airway pressure for 30 seconds. The alterations in the above mentioned parameters will be registered before and after the maneuver. The same procedure will be performed after a 8 ml/kg crystalloids fluid challenge, as soon as SVV reaches the value of 10%.
