Continuous Monitoring of Hemoglobin and Plethysmography Vari
A large French study has shown that monitoring both hemoglobin (SpHb) and plethysmography variability index (PVI) as part of a vascular filling algorithm allows for optimal transfusion among surgical patients, thereby reducing mortality. The researchers noted that inclusion of such noninvasive devices may significantly affect patient outcomes in the future, particularly among patients undergoing serious, more invasive surgeries.

“We know that anemia and inadequate volume filling are two important factors in morbidity and mortality after anesthesia,” said Nathalie Nathan, MD, the head of the Department of Anesthesiology at Centre Hospitalier Universitaire de Limoges, in Limoges, France....
