April 22, 2026 updated by: Saif Eldeen Gamal Khalaf, Assiut University
Effect of Pressure-Controlled Volume Guaranteed Versus Volume-Controlled Ventilation Modes on Hemodynamic Outcomes and Respiratory Mechanics During Laparoscopic Abdominal Cancer Surgeries With Exaggerated Trendelenberg Postion : A Randomized Controlled Trial
The primary outcome is to compare the hemodynamic outcomes ( e.g SV , CO and CI ) using The ICON of two different modes of ventilation ( VCV and PC-VG ) during laparoscopic abdominal cancer surgeries with exaggerated trendelenburg position.
And the secondary outcomes is to compare the respiratory effects ( e.g atelectasis development , plateau pressure(Pplat) , peak inspiratory pressure(PIP) , dyn. compliance and postoperative inflammatory indicators e.g CRP and WBCs ) of two different modes of ventilation ( VCV and PC-VG ) during laparoscopic abdominal cancer surgeries with exaggerated trendelenburg position.

Intervention / Treatment |
|---|---|

Experimental: Volume controlled ventilation ( VCV )
|
electrical cardiometry estimates cardiac parameters by measuring changes in thoracic electrical bioimpedance during the cardiac cycle.
The ICON, using four electrocardiogram (ECG) electrodes, estimates the maximum rate of change of impedance to peak aortic blood acceleration based on the principle that red blood cells change from random orientation during diastole (high impedance) to an aligned state during systole (low impedance).
This device estimates CO, cardiac index (CI), stroke volume (SV), systemic vascular resistance (SVR), and a variety of other cardiac parameters ... Lung ultrasonography (LUS) in patients who are under anesthesia and scheduled for surgery can detect intraoperative atelectasis, and the LUS score is correlated with perioperative oxygenation impairment
