Objectives

Narrative objectives1

Ovarian malignancy surgery is a highly invasive procedure with a high transfusion rate. On the other hand, as transfusion has been reported to worsen the prognosis of cancer, systemic management to reduce blood loss needs to be considered. The aim of this study is to investigate whether intraoperative ventilatory management in ovarian cancer surgery, mainly by intervening with end-expiratory positive pressure (PEEP), can reduce blood loss.

Interventions/Control_1

Low-pressure ventilation and low venous pressure interventions are continued from the start of surgery until the end of surgery.
The intervention group is managed with zero PEEP and TV 6 ml/kg, and preferentially with norepinephrine and no artificial colloidal fluid for pressure boosting purposes.

Interventions/Control_2

In the control group, PEEP of 5 cm H2O or more is added, TV 8 ml/kg is managed according to usual practice, and there are no restrictions on infusion management or use of vasopressor drugs.
