Body position may predict fluid needs during keyhole hysterectomy

This study looks at how a simple monitor called the Pleth Variability Index (PVI) changes during laparoscopic-assisted vaginal hysterectomy. Researchers will track PVI at six key moments when the patient's body position changes, such as tilting the head down or raising the legs. The goal is to identify which factors—like body mass index or abdominal pressure—best predict a significant PVI shift, which could help guide fluid management during surgery. Fifty adult women scheduled for this procedure will take part.
