Positive end-expiratory pressure ventilation, Optic nerve sheath diameter
Brief summary
The investigators aim to investigate the effects of positive end-expiratory pressure ventilation on intracranial pressure assessed by sonographic optic nerve sheath diameter in patients undergoing robot-assisted laparoscopic prostatectomy.
Detailed description
Effects of positive end-expiratory pressure ventilation on intracranial pressure have not been evaluated in patients undergoing laparoscopic surgery. We aim to investigate the effects of positive end-expiratory pressure ventilation on intracranial pressure assessed by sonographic optic nerve sheath diameter in patients undergoing robot-assisted laparoscopic prostatectomy.
Interventions
Mechanical ventilation with PEEP 8 cmH2O
