Official Title: Impact of Pleth Variability Index-Guided Acute Normovolemic Hemodilution on Intraoperative Fluid Management and Postoperative Complications in Cardiac Surgery

Brief Summary: Acute normovolemic hemodilution (ANH) is a widely used blood conservation strategy in cardiac surgery aimed at reducing intraoperative blood loss and the need for allogeneic blood transfusion.However, inadequate or excessive fluid replacement during ANH may lead to hemodynamic instability and other complications.The Pleth Variability Index (PVI) is a noninvasive dynamic parameter that can predict fluid responsiveness and guide goal-directed fluid therapy during surgery.This study aims to evaluate whether…
