Operative Hemodynamic Optimization Using the Plethysmographic Variability Index During Orthopedic Surgery

Operative Hemodynamic Optimization Using the Plethysmographic Variability Index During Orthopedic Surgery : a Multicentric Prospective Randomized Controlled Study

The purpose of this study is to determine whether an operative hemodynamic optimization using the plethysmographic variability index during orthopedic surgery could decrease the length of hospital stay and the postoperative morbidity.
