Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Mechanical ventilation mode:
PCV is an alternative mode of ventilation to VCV that is widely used in patients with elevated intraabdominal pressure and it has been shown to improve arterial oxygenation and decrease the peak airway pressure because of its decelerating inspiratory flow.

Mechanical ventilation will be administered continuously from induction of anesthesia until extubation. In the pressure-controlled group, the peak airway pressure not exceeding 35 cmH2O will be set to provide a tidal volume of 8 ml/kg, with and I:E ratio of 1:1,5. The respiratory rate will be adjusted to obtain an end-tidal CO2 of 35-40 cmH2O to be started with a respiratory rate of 12/min.

Treatment: Devices
Comparator / control treatment
VCV is considered as a control
Mechanical ventilation will be administered continuously from induction of anesthesia until extubation.
In the volume controlled group, the ventilation will be started with a tidal volume of 8 ml/kg and the initial tidal volume will be increased by 1 mL/kg every 5 minutes until 12 mL/kg. Respiratory rate will initially be set to 12/min with an I:E ratio of 1:1,5 and will be increased by 2/min every 5 min till 20/min to maintain an end-tidal CO2 between 35-40 mmHg.

Summary
Brief summary
The aim of this stydy is to compare the effects of volume-controlled and pressure-controlled ventilation on cardiac output changes in patients undergoing robotic assisted gynecologic surgery in steep Trendelenburg position.
Hypothesis: PCV may be a more effective method for maintaining more stable haemodynamics.
