Comparison of Volume Controlled Ventilation and Autoflow-volume Controlled Ventilation in Robot-assisted Laparoscopic Radical Prostatectomy With Steep Trendelenburg Position and Pneumoperitoneum

The steep trendelenburg position and pneumoperitoneum during laparoscopic surgery have the potential to cause an adverse effects on respiratory mechanics and gas exchange. Autoflow-volume controlled ventilation may improve lung compliance and reduce airway peak pressure. Therefore, the aim of this study is to evaluate whether Autoflow-volume controlled ventilation improves gas exchange and respiratory mechanics in patients undergoing robot-assisted laparoscopic radical prostatectomy.

Inclusion Criteria:

1. Adult male patients scheduled for elective robot-assisted laparoscopic radical prostatectomy undergoing general anesthesia

Exclusion Criteria:

1. chronic obstructive respiratory diseases
2. heart failure
3. body mass index (BMI >30 kg/m2)
