Effectiveness of Finger and Forehead Plethysmographic Variability Index Monitoring in Pediatric Patients

In pediatric surgical patients, the sensitivity of forehead and finger PVI monitoring was similar for the prediction of fluid responsiveness, whereas the specificity of forehead monitoring was higher. The use of forehead PVI probes in the fluid management of these patients seemed to be appropriate because cephalic region was not affected by low perfusion states.
