This is a prospective cohort study designed to assess intra-abdominal blood volume and hemodynamic status by measuring the diameter of the inferior vena cava (IVC) using 3D and Doppler ultrasound within 24 hours after gynecological surgery. The study will examine the association between these ultrasound findings and postoperative outcomes, including hemoglobin drop, need for blood transfusion, pain, infection, and length of hospitalization. Approximately 250 women undergoing laparotomy, laparoscopy, or vaginal surgery at Holy Family Hospital will be enrolled. The study also aimed to define postoperative normograms for fluid volume and IVC parameters and to evaluate whether ultrasound-guided decision-making could improve postoperative care and reduce unnecessary interventions.
