Abstract

OBJECTIVE: To investigate whether the pleth variability index (PVI), derived noninvasively from a pulse oximeter probe, would predict fluid responsiveness in patients undergoing noncardiac surgeries. DESIGN: A clinical, prospective, observational study. SETTING: Operating room of a tertiary care hospital. PARTICIPANTS: Twenty-nine adult patients undergoing a range of noncardiac surgeries, requiring general anesthesia, tracheal intubation, and mechanical ventilation. INTERVENTIONS: Intravenous volume expansion with 500 mL of colloid following induction of general anesthesia and after a period of hemodynamic stability before the start of surgery. MEASUREMENTS AND MAIN RESULTS: Baseline values ..
