Comparison of pressure controlled ventilation with volume controlled ventilation mode in patients undergoing laparoscopic gynaecologic surgery - A randomized control study

• This study is randomized single blinded parallel group study which compares the effects of volume controlled ventilation with pressure controlled ventilation in patients undergoing laparoscopic gynaecologic surgeries.

Laparoscopy has evolved from a limited procedure to a versatile surgical tool for various gynecologic and non-gynecologic indications. However, it can impact respiratory function due to decreased functional residual capacity and increased airway pressure. Modern respirators enable mechanical ventilation in various modes, including pressure-controlled ventilation (PCV) and volume-controlled ventilation (VCV). PCV offers faster tidal volume delivery and diffused gas distribution, potentially resulting in lower peak airway pressure and reduced risk of barotrauma. Despite these advantages, PCV is rarely used in laparoscopic gynecologic surgery, and the choice between VCV and PCV is often based on personal preference rather than clear guidelines. This study aims to compare the effects of these ventilation modes on respiratory mechanics and hemodynamic parameters in patients undergoing laparoscopic procedures and will be helpful in determining the optimal mode of ventilation in patients undergoing laparoscopic gynaecologic surgeries.
