Intraoperative Electrical Impedance Tomography in Obese Patients Undergoing Robotic Assisted Radical Prostatectomy.

Optimization of Intraoperative Ventilation Guided by Electrical Impedance Tomography in Combination With Oxygen Saturation by Pulse Oximetry (SpO2) Versus SpO2 Alone in Obese Patients Undergoing Robotic Assisted Radical Prostatectomy: Prospective Randomized Trial

The primary objective of our study will be verify a possible improvement in arterial oxygenation in the obese patient undergoing robotic-assisted radical prostatectomy if the ventilation will be guided by electrical impedance tomography rather than peripheral saturation alone.

Inclusion Criteria:

• Patients scheduled for laparoscopic radical prostatectomy
• BMI ≥ 30 kg/m2

Exclusion Criteria:

• surgery duration < 2 hours
• history of lung diseases
